Thousands of RGB Equations

We're laying out a book in InDesign. The client has exported thousands of equations from MathType. They look black but they're actually RGB. What's the easiest way to convert these objects to CMYK black? Can it be done using the convert colors dialog in Acrobat after the PDFx is made? If so, what settings should be used? I don't know what all the options mean.

If you're using InDesign then simply export it with a color conversion profile applied - no need to fix it later in Acrobat. For example if you have a print intent, export to PDF/X-1a and everything will convert to CMYK since that standard won't allow anything else. If you need a different PDF setup to retain interactive stuff etc., select Convert to Profile in the PDF export dialog under the Output tab, and pick something like SWOP2.

  • Fonts missing in MathType EPS equations

    Hope someone can help me!  Have an InDesign file, originally created in 2010 using CS4.  Now using CS6 to update.  Original layout had a placed Word document containing thousands of MathType equations; for some of the content the writer typed directly in the body of the Word file (x + y = z); others he used MathType to create the equations, which are now linked as EPS files in the InDesign file. 
    Our problem is some of the linked EPS files are not showing the correct font.....where the fonts should be Times New Roman italic, we are seeing Helvetica in our InDesign layout.  The preview icon next to the linked EPS image (on the left in the Links palette) is showing the correct italicized text.  When I open the problem eps files in Illustrator, the font that's supposed to be the Times New Roman Ital is getting substituted with Myriad Pro.  BUT when I open the problem EPS files to edit them in MathType 6.7, the italicized Times New Roman font appears correctly. 
    This problem is inconsistent...some MathType generated eps equations are fine and will appear right next to some that aren't (even the same equations!)   Am not getting any font error messages in InDesign; have tried turning on/off Times New Roman in Suitcase and Font Book.  Have tried deleting cached font files.
    Again, the document has thousands of equations so can't just manually open up each in AI or MathType to fix/swap fonts.  Have had some success bringing sections from original 2010 Word file into a fresh CS6 document but it's not an option to re-layout the entire document.
    Any ideas?    Am tearing my hair out!    THANKS!

    So, anyhow: you have PICT files with embedded PostScript.
    It's not super-surprising to me that they are hard to read and InDesign doesn't do what you expect.
    Also, they are malformed, or at least mutant, because their embedded raster image is in a different font their embedded PostScript.
    Preview.app can read them if you rename them to .pict first.
    It gets the fonts right.
    I am not really familiar with PICT files (aka QuickDraw Picture Comments?). I just spent far too long slogging through the legacy apple reference, Imaging With QuickDraw. Ow my head hurts.
    Ideally you want to mass convert these files to EPS (or some other reasonable format).
    I don't know how you should do that.
    Hopefully MathType can offer you a solution.
    Maybe MathType is scriptable with AppleScript (I dunno, I don't have it).
    That's about all I can do. Hopefully someone else can help you out.
    Oh, I suppose a fallback would be to script Preview.app. It can open them and save them as PDF. But unfortunately it saves them as raster images (of high resolution) and of course they are not further editable in MathType. But it is possible to script Preview.app, so you could do a bulk conversion there.
    Oh, another choice is to extract the PostScript from the PICT file by hand/magic/handwave/whatever and then doctor it so that it does work. This is actually kind of straightforward, you just replace
    currentpoint 3 -1 roll sub neg 3 1 roll sub
    1888 div 512 3 -1 roll exch div scale
    currentpoint translate 64 8 translate
    with some scale factor that works, like:
    0.1 0.1 scale
    Unfortunately, this seems to give...messed up font positioning:
    so it's probably not the way to go. (And is that x backwards???? Umm… )
    Anyhow, yeah. Happy New Year.

  • When will we get support for equations in Keynote for iOS?

    I was delighted to get an iPad a year ago, thinking that now I would not have to lug the laptop around to scientific meetings and lecture halls. But when I downloaded my carefully prepared Keynote presentation to the iPad, I learned that Keynote on the iPad does not support equations. So, back to the laptop, copy all the equations and re-insert them as uneditable PDFs.
    But that's clearly only a work-around. If I need to change anything, it's back to the laptop for editing. And for a course consisting of a dozen lectures and a total of a thousand or so equations, the only sensible option is to lug around the laptop.
    Surely (I thought) this is just an oversight that will be remedied in the next release of Keynote for iOS. But I've waited through several new releases, and still haven't seen support for equations added.
    Not only that, but many quite ordinary fonts are not available in Keynote for iOS and there seems to be no way of adding them.

  • VGA signal output type mDP-VGA adapter

    Howdy.
    Working on a way to plug our new mini (early 09) into a crusty ol' analogue tv, whose best quality input is up to 576p component. Tv manual say to plug component source (either YPbPr, YCbCr or Y B-Y R-Y) into the component input on the tv (Y Pb Pr).
    My understanding of signal types is limited, and I am looking at a VGA to component converter as my first preference option since svideo and composite are so crusty.
    Can anyone be really specific on the exact type of signal output from the miniDP-VGA adapter? As far as I know, most computers output a vga signal referred to as RGB, which SOME tvs can read via component in. Can anyone tell me if this RGB equates to any of the above signals (such that i could simply use a vga-component cable that I already possess), or if i will definitely need to get a converter box? I have plugged my older mac mini into the tv (using dvi-vga adapter supplied and then vga-component cable i purchased form some dodgy online ebayer) and had no luck.
    can anyone tell me the potential ramifications of messing around with this stuff? Can inputting incorrect signals damage any of my hardware?
    does anyone have any brilliant ideas on how to run an early 2009 mac mini into a tv via component? At this stage it is going to cost me around $200 for a decent converter box , and being a younger generation I want a solution ASAP and would prefer not to wait weeks for shipping from the States.
    It seems as though the new minis only do dvi-d, while my older one has dvi-i - this is why the dvi-video adapter is not compatible with the early 09 models. i have spoken to apple tech support several times but it seems as though they are getting their dvi types mixed up and don't understand my predicament fully, as their suggestions are not possible with dvi-d. Is there such a thing as a DVI-d to DVI-I adapter? Would it make any difference?
    Any clarification people have to offer on this one would be greatly appreciated.

    A few comments; first off, you can't damage a TV with wrong signal types, although some old TVs can be damaged from wrong timings. That's going to depend a lot on the TV's age whether it has a more modern, multi-sync type chassis or not.
    The Mini DVI output on the new mini is DVI-I. That is how it is able to support the Mini DVI to VGA Adapter that Apple sells for the new mini. But you are right it no longer supports the Mini DVI to Video Adapter. But that is an issue with drivers and has nothing to do with the mini having a DVI-I output or not. But it is definitely Mini DVI-I.
    So to connect a component converter box, you could use either the Mini DisplayPort or the Mini DVI output of the mini. I would tend to recommend the Mini DVI as being somewhat more standard. However, a Mac really wants to see something called a plug-and-display driver, which is also known as EDID, whenever it is connected to a display. So try and see if you can find a component video converter having a VGA input that has an EDID loaded into it or else the Mac will not be happy and it could all be money down the drain that would have better been spent on a new TV.
    Hopefully you will get some more specific information from someone else. Good luck.

  • 'Convert CMYK Colors to RGB' still runs havoc in 9! (Plus a PDF version problem)

    This post is to warn people about severe issues, and how to avoid them. Issues with the CMYK color setting in FM9.x have been reported here earlier, such as:
    http://forums.adobe.com/message/1237696#1237696
    http://forums.adobe.com/message/1237852#1237852
    http://forums.adobe.com/message/1237165#1237165
    However, I do not think this issue has been warned about anywhere near as much as it should have. And, as usual, Adobe is silent (they should have a big poster on their site warning about this issue! And they have even claimed that patches have "solved" the issues with CMYK).
    Just recently, while experimenting with FM9 again, I had extreme problems, which, at first, seemed totally unrelated to this CMYK setting. But after having struggled extremely hard for many many many hours, I finally found out. Now is the time to inform others:
    First a note about versions: FrameMaker 9.0p237, Acrobat Distiller 9.1, XP SP2
    It looks perfectly okay on screen in FrameMaker, exactly as in FM8. But when saved as pdf, several things are "corrupted". Examples: no kerning after the letter 'T', such as the word 'Text'. Dotted leader for a right aligned tab disappears. Some objects from the master pages, such as a logo, become enclosed in a rectangle (a border of the frame/object), but it only happens on *some* body pages, whereas other body pages using the same master page are ok!!? Equations are formatted differently from the way they should, with the wrong font for number, etcetera.
    Solutions:
    1. When 'Save as PDF...', untick 'Convert CMYK Colors to RGB' in PDF Setup. Same setting is in the file's 'Format > Document > PDF Setup...'
    A drawback with this method is that, as of Acrobat Distiller v9, it does not seem to respect the pdf version specified in the PDF job Options! I get PDF 1.6 with this method, despite my job option specifies version 1.5. (This happens also with FrameMaker 8 if Acrobat is v9.) So you *have* to optimize it in Acrobat in order to get a web friendly PDF (PDF 1.4 or 1.5).
    or
    2. Print to 'Adobe PDF'.
    In this latter case, you can set the same 'PDF Setup' settings under the button 'Setup...', EXCEPT that there is no tick box for 'Convert CMYK Colors to RGB', and it does not matter what setting you have chosen in the file's 'Format > Document > PDF Setup...', it will be RGB conversion in any case. Make sure that after you exit the setting, the tick box for 'Print to File' is NOT ticked! This method respects the pdf version specified in the PDF job Options! I get PDF 1.5, which is what my job option specifies.
    (For some reason, Acrobat/Reader does not render these two PDFs exactly the same, except in extreme magnification! Maybe it has to do with the different PDF versions of the files.)
    In either case, the solution actually solves ALL problems I listed! Despite it seems to have absolutely nothing whatsoever to do with colors! Some day in the distant future, CMYK might actually work! But, for myself, I would prefer a proper color management instead...
    Best Regards,
      /Harald

    Oops!! Not until now I discover that under 'Solutions' I happened to write 'untick' where it should be 'tick'! I.e, colors SHOULD be converted to RGB in order to circumvent the problems! I.e it runs havoc in v9 when CMYK colors are NOT converted to RGB! Don't know how I came to write the opposite, but probably I started out by describing the situation where the problems are seen rather than describing how to avoid them.
    Equally strange is that nobody corrected me, but perhaps the mistake was so obvious? (But whether you see problems or not might depend on what fonts you use. So, under certain special circumstances, CMYK might actually work without these reported problems.)
    I am also a bit surprised that others haven't reported the issue that the PDF version set in PDF job Options isn't respected when using 'Save As PDF' and Acrobat 9? (Or maybe someone has, but I have missed it.)

  • Question: Anybody know the relationship between raw temp & rgb temp?

    I am trying to normalize relative  temperature adjustments for proper application to both raw files and rgb  (e.g. tiff/jpeg).
    Presently I divide the raw temperature offset by 100 to keep from over correcting tiff/jpegs. This  works sub-optimally. - Anybody know a better formula?
    for example, at present I have: delta raw temp / 100 = delta jpeg temp. Thus if I would apply 500 degrees warmth to a raw, it would translate to 5 units of warmth to a jpeg, which is usually a little light handed, but not always - depending on starting point. Any of you geniuses know an actual formular or equation to translate incremental raw temp to incremental rgb temp?
    It doesn't have to be exact - any improvement over the simple (starting-point independent) proportionality (ratio) would help.
    Thanks in  advance,

  • RGB to CMYK without losing quality

    How can I convert a photoshop file, which is in RGB, into CMYK image mode without losing quality?
    Whenever I try to convert the image mode, it totally changes the colors making it damn ugly. I want the brochure to be printed and for that it should be in CMYK format.
    Kindly help me. Its urgent.
    Thanks in advance.
    Regards,
    Snehal Masne

    Snehal,
    A lot depends on the particular colors you're using in RGB, what sort of CMYK printer or press you're using and just how you're actually converting to CMYK. Most images print just fine in CMYK, as can be seen by the many thousands that print every day in magazines and newspapers around the world. CMYK's weakest areas are bright saturated blues, which will always print like crap because the inks just cannot print those colors. You haven't told anyone exactly why your conversions look like crap, only that they do. If you posted an example, more specific help could be given, but the bottom line is that there are always going to be some compromises going to press and you, as the designer, have to take those possibilities into account when doing your design. You can also trick the viewer's eyes into thinking the image is more saturated than it really is by intelligent use of color contrasts in images and designs. For instance, using a bright yellow, something that presses print quite well, next to the best blue you can print, will make that blue appear bluer and more saturated than it really is. Of course, if you need exact and specific color matches, you can always go to additional spot color plates using Pantone or other color inks, at an added cost in both money and complexity.
    Entire books have been written on this subject, and for good reason.

  • HP Prime issue on solving C=S/M equation

    Hi,
    I am trying to solve a simple equation C=S/M in the solver app.
    If I start from scratch I do get results with small numbers for S & M. However, when I use large figures (1,900,000/2,000,000), I receive a "Bad Guess(es)" error. The strangest thing is that if I use the emulator in my PC, I always get the right result without any issues. I have tried using other variables, clearing them all together and it always comes back to the same issue. I have also tried with Solver variables and user variables and it has no benefit
    It looks like the variables are not updated when I enter new values in the Numeric view of the Solver app. But that is too large an issue to really be it.
    Thanks in advance for any support.
    Carlos

    Never mind... I found the solution, however odd it is.
    I was trying to solve the easy equation C=S/R and occasionally obtain the Bad Guess(es) error when the numbers were large (C=1,900,000/2,000,000) for example. Once this happened, the solver would not even work with lower magnitude numbers.
    I noticed that it appeared that the variables in the equation were not updated when I keyed in the numbers in the Numeric view of the Solver app.
    If I performed the same solving process with the emulator in my PC, I had no issues whatsoever, regardless of the magnitude of the numbers.
    Then after reading that the latest firmware update provided the Digit Grouping option, I sort of imagined something could be wrong with it when large numbers were keyed in. Anyway, the emulator does not have this option set in the software and it worked, so it sort of led the way.
    I finally went to settings and selected a Digit Grouping option with no thousands separator and voila... it worked smoothly.
    I think it may be something related to how the numbers are displayed vs how they are stored in the variables that led to this issue.
    Hopefully if someone gets to this same issue, she/he would get some info about it. I also posted this in the Google group in case someone in the HP team may see it and directed so that in a future firmware it is solved.

  • Conversion formulas from RGB to CMYK

    Hi,
    I've been writing a Colour swatch tool (in excel! hell yeah!) which allows me to pick a bunch of colours, generate complimentary colours from them, blend between 2 colours in a set number of steps and a whole bunch of other cool stuff, and then output this as a photoshop or illustrator swatch file.
    As part of this tool I want to be able to covert the rgb values to cmyk. There is very little information on this on the web and what there is is fairly inaccurate.
    For example,
    RGB:50,128,128
    Converts to CMYK 61,0,0,50 (%) using the formula found at easyrgb.com (this formula is the most prevalent one on the web/web forums)
    Photoshop converts these RGB values as CMYK: 80,33,48,8 (%)
    While these two colour values are *similar* the ones generated by the easyrgb formulas are nowhere near the photoshop values.
    See? stupid useless formulas. (I am aware of the differences and overlap of the two gamuts)
    Whilst I know that the conversion done in photoshop is done using ICC templates, and that often these conversions are device dependant, there must be a more realiable way of converting from one colour space to another using good old reliable cold hard maths.
    Does anyone know what that might be? you guys at Adobe: I AM LOOKING AT YOU.
    Hope you guys can help,
    ~silvery~
    For reference I have included and commented the easyrgb formulas:
    First: RGB -> CMY
    C = 1 - ( R / 255 )
    M = 1 - ( G / 255 )
    Y = 1 - ( B / 255 )
    Second: CMY -> CMYK
    var_K = 1
    Initally sets var_K as 1, although this is dependant on variables below
    if ( C < var_K )   var_K = C
    if ( M < var_K )   var_K = M
    if ( Y < var_K )   var_K = Y
    This bit finds the smallest value from the CMY range and sets this value as var_K
    if ( var_K == 1 ) { //Black
        C = 0
        M = 0
        Y = 0
    If var_K (the value that K is calculated from) is 1, then all the CMY values are reset to 0
    else {
        C = ( C - var_K ) / ( 1 - var_K )
        M = ( M - var_K ) / ( 1 - var_K )
        Y = ( Y - var_K ) / ( 1 - var_K )
    If the value of var_K is anything other than 1 then use the smallest value from the CMY range
    K = var_K
    The value of K as filtered out from the conditions above

    Oliver,
    I'm not sure what you mean by the term 'meta' color profiles, but I'll take a stab at what I "think" you are asking.  There are some fairly widely accepted "standards" out there for both RGB and CMYK.
    In the RGB world, for example, sRGB, Adobe RGB (and to some extent, ProPhoto RGB) have a fairly wide following. These are all ICC profiles, which nail down the boundaries of the color gamut and the definitions of any tri-stimulus combination of red, green and blue. Basically, they are matrix profiles that establish the positions of the Red, Green and Blue primaries, and these positions define the outer limits, or color gamut, of the color space. sRGB is a relatively small color space, so some viewable and printable colors get clipped (sRGB is the general internet, email standard and is widely assumed for many non-color managed appplications, printers, etc). sRGB can handle a fairly wide range of colors, but does clip some colors in brightly colored originals. It has the advantage of being the most widely adopted standard, plus the steps between colors are very close together. I use sRGB for average images, most people pictures, etc. Adobe RGB spreads the primaries further apart, so it describes a wider color gamut. Because the primaries are further apart, the steps are slightly larger from one color to the next, but marginally so. I use Adobe RGB for most of my brightly colored images that will get clipped in sRGB. Adobe RGB is also generally a good choice for images that will ultimately go to a printing press or inkjet. ProPhoto RGB pushes the primaries WAY apart, so it describes a HUGE color gamut...in fact, many of the colors that can be defined in ProPhoto fall outside human vision, and certainly monitors and printers.Due to the wide spacing of steps in ProPhoto RGB, images should be worked in in 16 bit, otherwide you may see some banding and posterization if large edits are made.
    In the CMYK world, certain "standards" have been established, mainly for commercial offset printers (both web and sheetfed presses). By creating a standard, they are trying to establish the ink limit, densities, color gamut, dynamic range, gray balance, etc, of a "generic" sheet of commercial printing paper on the average well-maintained press using standard ISO inks, using good process control, mesurements, etc. By it's nature, this process has to encompass a wide cross section of presses, so it may act as a limitation on what some modern presses are capable of, but that's what standards usually do. If a good printer, with a modern press and great process control decides to sidestep the standard, they can probably extend color gamut, dynamic range, etc, but at the cost of no longer being "standardized". If commercial printers are "truly" trying to meet the standard, they will run tests, take measurements, and adjust their entire workflow so it matches the standard, within acceptable tolerances. Lots of shops "claim" to adhere to SWOP or GRACoL standards, but the majority of them don't. Standards for presses make some sense, because blending CMYK inks together (especially if they use ISO standard inks) on paper usually has a reasonably narrow range that works, though the paper makes a huge difference. (the same cannot be said for inkjets, monitors and many other processes, so they generally do not have standards). So for presses, there are standards for matte and coated papers, web presses, sheetfed presses, newsprint, etc. Each of these standards has its own ICC profile (or a family of profiles) that establishes ink limits, color gamuts, etc.
    All ICC profiles have the necessary tags and data to comply with the ICC specification. One of those requirements is a "profile connection space", which is usually L*a*b* or a variant. So, an file on your computer may be tagged as an Adobe RGB file, and if you wish to prepare it for a sheetfed press using glossy stock, you could convert the file to GRACoL2006_Coated1v2.ICC (an industry standard profile for No. 1 coated stock on a sheetfed press). Since both files have the ability to "speak Lab" a translation can be made from one color space to the other. The numbers in the Adobe RGB file will be converted to L*a*b* (the universal translator), and then the L*a*b* numbers will be converted to CMYK, specifically GRACoL2006_Coated1v2.ICC. So, now you have a file in CMYK space with new numbers. It is worth noting that RGB has only three colorants to define colors, but CMYK has four. So, while in RGB there is only one way to define a specific color, in CMYK, there are many possible combinations that can generate many colors. This adds complexity to the equation. The CMY colors are called subtractive primaries, and are opposites of RGB (additive primaries). The "K" (black ink) is added for text, line art, neutrality, extra Dmax, and because the CMY inks are not pure and don't deliver a true black all by themselves. If the inks and paper were perfect, you could theoretically get away with CMY all by themselves, except for registration issues, text, line art, etc. Also, the additional "K" ink can help reduce the total ink limit, save ink, reduce costs, and improve quality.
    Sorry for the book. This is not a simple subject, and we have only touched the surface.

    While this will work, and is a direct translation, it is hopefully
    not what you will be doing very often. This -- read local, modify,
    write local
    -- is what you might do if the code needs to update the
    user interface.
    Another translation is to take the value on a numeric wire. If the
    value of the wire is A, then drop a numeric increment node, wire
    the A wire to the left, and from the right side comes A+1. Now
    wire the value to wherever it is needed.
    This may not seem like much of a big deal, but if these literal
    translations are applied too often, the LV diagram ends up being
    lots of small read, modify, write code snippets that then need
    to be sequenced. The writes are often made to an open panel which
    needs to redraw things, and that takes thousands of times longer
    than updating the variable. Basically, too much of this leads to
    a diagram that is hard to modify, hard to debug, hard to read, etc.

  • Can you show slideshow within Lightroom 4.4 in Adobe RGB color space?

    Can you show slideshow within Lightroom 4.4 (not export out from LR) in Adobe RGB color space provided that you are using a wide gamut monitor which is capable and hardware calibrated & profiled to show such color space?
    If this is possible, what is required to do so in Windows 8 and i7-4770 & HD Graphics 4600 platform or does LR take care of it automatically?
    This is very basic question, however, I could not find a clear answer/info from LR documentation, so wish that someone can advice.

    Those settings are probably stored in a plist somewhere in ~/Library/Preferences. If you can locate the appropriate file, you should be able to copy it to all the network user folders.

  • Is there a way to open two color windows? I want to use both HSB and RGB sliders and have them side by side. If there isn't a way, how would I go about creating my own script for it?

    Here's an example of what I mean:

    I would have access to both RGB and HSB at the same time instead of constantly switching back and forth. Any input on this matter would greatly help thank you!

    Photoshop only has one Color Palette.  If you could script something  like a Color Palette with  two sets of active sliders the script would be in control till you dismissed its sliders dialog.  You would not be able to do anything but adjust the script's sliders in Photoshop while the script dialog window is being displayed.  Photoshop Scripting does not have real palette dialog type support.
    I do not know what is possible with Photoshop extensions using HTML 5 Panels.....

  • ? Selecting 2 of 3 RGB channels in to adjust in Levels

    This is a CS4 question (and let me express my ingratitude to Adobe for dropping support for an $1800 set of apps).
    In Photoshop CS4, using a G5 (non-Intel), in the Channels view panel (alongside Layers, etc), when it is displaying RGB, Red, Green,and Blue I am able to shift-click, on say, the Red and Blue channels to sleect only those two. The image still displays in full RGB. When I issue command-L (Levels) I end up with the basic Levels disalog box, and instead of it choosing by default "RGB" for adjusting, I now have "RB" and I can adjust Red and Blue together with the sliders, avoiding the green channel. I can do this in, obviously, three combinations.
    For some reason, when I try this same thing on a friend's Intel Mac with Photoshop CS4 (same!), shift-clicking the Red and Blue channels in the Channels palette chooses them but the image display now displays without the Green channel influencing the image, thus rendering it unusable for adjusting two channels at once.
    I figure that since I am using the same App version on each Mac, maybe there is a setting somewhere I cannot find, or I am forgetting a step on the way to my friend's computer.
    Q: How do I choose 2 channels in the Channels palette while still having my image display in full color, and also be able to choose those two channels for adjustment in the Levels?
    For those of you who are wondering WHY I would want to adjust 2 channels at once, here's an example: an image looks lsightly too yellow, bt ther eis no yellow channel. Yellow is full Red & Green, so, using my method, I can choose both those channels, and reduce the yellow by reduing R and G together.

    You should be able to shift click the red and blue channels, then make the rgb composite visible (make the EYE visible by clicking in that box)

  • Photoshop gives, Program Error, when attempting to use blending options in RGB

    This problem started today when i tryed to throw a drop shadow on a layer. in RGB mode.  "Program Error," appeared and would not let me access any Blending options.  Although, in cmyk mode it works perfectly fine.  Was some hotkey hit on accident or has something gone wrong?  Help!
