Need Info on RGB to CMYK

Hi,
I am new to Illustrator (CS5) and not fully comfortable with RGB vs CMYK.  For instance, I created a logo for use on the web using Document Color Mode: RGB where my background color in RGB is 0, 0, 130.  When I create a Print document using Document Color Mode: CMYK and copy the logo into the print document, it converts that background color to CMYK (C:100, M:98, Y:16 K:18) where the RGB is now (44, 45, 111).
Is there a way to get a closer match to the original RGB color 0, 0, 130?  When the specifications for the print advertisement says images must be in CMYK,  I hope I am accomplishing this by using the Print Document Color Mode of CMYK vs RGB?  I feel somewhat ignorant on utilizing the RGB vs CMYK color modes and if anyone can give me a tip on what techniques they use to get a closer match of colors for RGB to CMYK or vice versa, I would love to hear it.
Thank you,
Keith

Keith,
First, be aware that you have posted to the Photoshop forum, not the Illustrator forum. The general concepts of color and color management are the same across the spectrum of digital imaging. However, its implementation is slightly different from application to application, so you may also want to post your question to the Illlustrator forum.
[EDIT: Brain fart on my part... This is the color management forum, NOT the Photoshop forum, so you are in the right place! (I spend most of my time in the Photoshop forum; I lost track of where I was...)]
That said, you're running up against a general concept: color gamut.
The color you've spec'd in your RGB file (0/0/130 - and we'll assume for now that it's in the sRGB color space) is outside the gamut of every CMYK color space. That means that the RGB color you see can not be reproduced using a mix of the four CMYK process colors (cyan, magenta, yellow, black). When converting to CMYK, the software picks the closest color that is within the gamut of the CMYK space, hence the color shift.
When you're designing for CMYK, it's best to work in soft-proof mode which allows you to see a pretty close approximation of what your colors will look like in the final color output space - in your case, CMYK.
In Photoshop, to turn on soft-proof, go to View > Proof Setup> Custom... and choose the CMYK output space that matches the press conditions you are designing for.
There are books written about this, but hopefully this short answer points you in the right direction.

    Yes, it will be a problem. Convert the images in Photoshop using the printer's color profiles or a standard CMYK profile.

  • 'greyscale' RGB image, need to convert to specific CMYK black...  how?

    Hi,
    I have an image provided in RGB, but visually it's greyscale, except for some red areas on certain clothing. I need to convert it to CMYK, and I want all the black areas to be 40/30/20/100, and the grey values should be percentages of this mix. The red should be visually unaltered. Im using CS3 btw.
    Is there a way to quickly do this? I can convert to a generic CMYK value then tweak the curves of each channel, but it will affect the red. I could make a selection to exclude the red, but i feel there must be a way for me to define my black, and convert, and for my wishes to be granted automagically.
    I tried redefining my default black in the foreground/background swatches, but that had no effect on the subsequent conversion.
    Also, I'm trying to avoid profiles as my brain is foggy in that area...
    Thank you,
    Simon Gregory

    Without seeing the image, it might be a shot in the dark, but what about creating a new CYMK document, of the same size as the RGB one. Add a layer filled with the 40/30/20/100 black.
    Go to the RGB image, In the Channels panel, drag the red channel to the new channel icon. Drag this new channel to the CYMK channel panel. Add a layer mask to the 40/30... layer. go back to the channels panel, and target only the copied channel, copy it, target the layer mask channel, paste. Target the Layer mask, invert it.
    Now, select and bring the red part from the RGB image, and you should be good to go...

  • RGB or CMYK colour formatting for iPhoto Albums printing.

    Hi.
    I'm putting my first iPhoto Album together. Info given from Apple about what colour format to use for your photos, says to use RGB. While this is corrcet for digital monitors and screens. Mass printing uses CMYK. Any images supplied to a printers in RGB will colour shift when printed in CMYK. No matter what a printer tells you, these colour shifts can be very noticable. I'm an Advertsing Art Director and I've seen the shift that happens.
    I will be checking/colour correting all photos submitted to the iPhoto Album with Adobe Photoshop. And many will very probably undergo some corrections. Be it through levels, curves, hue/saturation, etc. Nothing to anything near an excessive level, but enough to make obvious improvements.
    So I will then be faced with the choice of whether to save the images out in RGB or CMYK.
    Can someone with some technique knowledge, from the iPhoto team, tell me/reasure me why RGB has been specified? And if CMYK wouldn't actually be a preferable colour format to supply in, considering you'll be printing them in CMYK.
    Many Thanks, Jim.

    You're absolutely correct. I was referring to notes make a number of years ago in regards to iPhoto 5  and that RGB was recommended for both books and prints. 
    I was confusing CMYK with Grayscale with Dot Gain 20% profile when stating iPhoto didn't support it which it didn't fully support until iPhoto 9.
    In fact I just ran a test with iPhoto 6, 7 and 8 with a CMYK AND GrayScale files with the following results:
    iPhoto 6 (06): wouldn't import CMYK but did GrayScale.  The grayscale file would only display as a black thumbnail and negative full image.  If the DotGain 20% profile was stipped from it the iamge would dispaly normally.
    iPhoto 7 (08): wouldn't import CMYK but did GrayScale.  The grayscale file would only display as a black thumbnail and negative full image.  If the DotGain 20% profile was stipped from it the iamge would dispaly normally.
    iPhoto 8 (09): neither file would import which is surprising:
    iPhoto 9.2.3 (11):  both imported and viewed normally.
    iPhoto 9.4 (11):  both imported and viewed normally.
    In Oct, 2007 I got an email from Apple support with the following:
    Also as iphoto makes a pdf of the book and then uploads it to keep the size down, it doesn't matter if the pics are RGB or CMYK as a pdf is a closed file. But since it is going through prinergy it has an RGB checker so this most be switched off. It is how the software in prinergy handle's it that causes the washed out affect as it takes the Red Green Blue colours and tries to convert to Cyan Magenta Yellow Black. Now the colour spectrum in printing between rgb and cmyk is quite different looking at a colour wheel will show you. The best way i can describe it is if you have a pantone book which has spot on one side and process on the other you can see a colour difference. Or if you use quark open up the colours and again switch between process and spot.
    BUT ONLY CONVERT PICS TO CMYK IF YOU ONLY INTEND TO ORDER BOOKS. IF YOU INTEND TO ORDER PRINTS IT WILL NEED TO BE RGB.
    Here's how i see it:
    1. Apple doesn't want 2 different versions of the pics floating about as running CMYK through a photomachine (as prints you would order in the high street) will not print correctly.
    2. RGb's going through a CMYK press using prinergy will attempt to convert and produce the washed out effect, or yellowing effect BUT will still print.
    So it will use the 2nd option as it will still produce prints normally and books with a slightly washed out effect. Now to most people in the high street, who will notice a difference?
    I have just received my latest book saved as CMYK pics in tiff format and no washed out effect. What i will say is The quality if still not as good as a print. Now we use a docucolour 5252 at work and the colour quality is better. I wonder how often the machine is calibrated and what colour curve it is set to?
    However, I am unable to import a CMYK file in any iPhoto version until iPhoto 9. Go figure.
    Thanks for the feedback.  Hadn't addressed this particular subject in quite a long time.

  • Calendar images: RGB or CMYK? TIFF or JPEG?

    Why am I not finding this info anywhere? Prior to making a calendar and/or book, I'm going to edit my images in Photoshop, then save them out, but want to know in advance the ideal size (300 dpi at final size? At what line screen are the books/calendars printed?). Am I saving in CMYK as you would for regular 4 colour printing? Or do they need to be RGB? What format? TIFF files, again, as you would for normal 4-colour sheetfed offset printing, or JPEGs? Answers to these questions as a link on one of the myriad help pages would be nice.
    Thanks.

    Why am I not finding this info anywhere? Prior to making a calendar and/or book, I'm going to edit my images in Photoshop, then save them out, but want to know in advance the ideal size (300 dpi at final size?
    dpi has no mening for a digital photo - See The Myth of DPI for additional information. - you want to save at the full pixel size that you have for maximum quality
    At what line screen are the books/calendars printed?).
    It is not a printing press but a digital printer - the higher quality you have the better the print - any print that will print below 180 dpi gives you a warning
    Am I saving in CMYK as you would for regular 4 colour printing?
    No - iPhoto ONLY works with RBG images
    Or do they need to be RGB?
    Yes
    What format? TIFF files, again, as you would for normal 4-colour sheetfed offset printing, or JPEGs?
    Your choice - most people use JPEG to reduce disk storage - TIFF is fine too

  • Choosing profiles for forced RGB to CMYK color conversion

    When a mixed RGB/CMYK PDF is opened in Illustrator CS6, Illustrator forces a conversion to one color space or the other. See this screenshot: http://imgur.com/sK8iEdn
    I assume this is a limitation of Illustrator and there's no way to keep both color spaces. Under that assumption, Is it possible to choose the profiles used for the conversion from RGB to CMYK? Can Illustrator be made to use the RGB and CMYK profiles defined in its Color Settings to make this conversion?

    I did some experiments with Illustrator CS6 and the MacBeth RGB test chart and verified my results with Photoshop CS6. I discovered Illustrator is (mostly) doing what it should be doing, within a 1% error (probably rounding) on the output CMYK values. Here's a summary, in case anyone else needs this info:
    Assuming the source file's elements are all untagged, when a mixed RGB/CMYK PDF is opened in Illustrator and CMYK mode is
    chosen, Illustrator will use the profiles and rendering intent defined in
    Color Settings to make the color conversions from RGB to CMYK. Thus, we
    have control over the profiles used for this conversion.
    If the RGB elements in the PDF file have embedded ICC profiles,
    Illustrator will use the embedded ICC profile instead of the RGB profile
    defined in Color Settings. This ONLY happens, however, if the PDF file
    also includes the correct CMYK output intent profile.
    If the PDF doesn't contain a CMYK output intent, Illustrator will fall
    back on the Color Settings RGB profile for RGB->CMYK conversion. I believe it
    would be more correct for Illustrator to use the embedded RGB profile and
    the CMYK profile defined in Color Settings, but that's not how it seems to work.
    If the PDF contains the incorrect CMYK output intent, Illustrator will
    ignore the Color Settings and respect the embedded RGB and CMYK profiles
    for the conversion, as might be expected.

  • How can I convert Pdf from RGB to CMYK, keeping font color 100% K while working in Illustrator?

    How can I convert Pdf from RGB to CMYK, keeping font color 100% K while working in Illustrator?
    When I try to open the document in Illustrator and I convert to CMYK the black font converts to rich black, but to set up for Offset printintg I need the text to be only in Black (100%K).
    The original source of the document is a Microsoft Word file, I have converted the Word file to Pdf in order to setup for OFfset Printing.
    Thanks

    I have tried that way, but the downside is that the fonts are set in gray not in a 100%K, also I have to deal with other fonts that are composites and meant to stay Full Color. I could select text by text and convert to gray but, its a 64 page document and I wouldn't want to make a expensive mistake.

  • Rgb to cmyk

    Is there a way to change the color makeup of ads from rgb to cmyk? I was not the creator of these ads for my newspaper but the printer needs me to change them and get rid of the built black. So, I guess I just need to change the black to pure black.

    switch to CMYK color, add a Selective Color adjustment layer and change the Blacks

  • Rgb to cmyk turns white brown

    Hi Guys
    In previous versions - changing from RGB to CMYK or vice versa would change the colours slightly but ever since CC when I change one to the other my white
    goes brown and there is a yellow tone to the image.
    Has anyone else experienced this - it's not slight either see image. I haven't adjusted anything - the original CMYK is on the left and
    when I make it RGB - it goes brown.
    Has anyone else had this issue?

    I'd try a new display profile first. Recalibrate, or if you don't have a calibrator use sRGB (or Adobe RGB if your display is wide gamut).
    Everything in Photoshop passes through the display profile. If there's a problem with the profile it can happen that one conversion goes bad but not another.
    On Windows a common cause for this is bogus manufacturer profiles pushed through Windows Update. Mac isn't as susceptible to this, but there you have an added complication called ColorSync (which is where the actual profile conversions are done). So if a new profile doesn't fix it, you probably need someone with Mac OS X expertise.

    The image I posted in my post, was your "after" image CORRECTED by me as explained in that post:
    "Converting it to sRGB and setting the black and white points via a quick Auto Levels adjustment, brings about an improvement."
    In other words, I downloaded your "after" image, opened in Photoshop, went to the Edit menu and used Convert To Profile to convert it to the sRGB color space, then I ran and Auto Levels adjustment.  That's how I fixed your mess.

    Geebus Chrysler!  No, that is indeed not just "primitive" but totally wrong.  Go to the CONVERT TO PROFILE menu item in the Edit menu in Photoshop, and from that menu select the specific CMYK profile you want (or your printer requests).  Be careful to select CONVERT TO PROFILE, do not under any circumstances choose "Assign Profile"!  Converting to the appropriate CMYK profile will also automatically change the image mode to CMYK mode.

    Apple Custard, it's obvious that you have no clue as to what Color Management is, and teaching you Color Management step by step here exceeds the scope of what can be accomplished in a forum.  A good place to start reading up on it is here:
    http://www.gballard.net/psd/cmstheory.html 
    In a nutshell:  Your Monitor profile should be the file resulting from your calibrating and profiling your monitor with a hardware calibrator puck.  Calibrate and profile your monitor regularly and often.  Your monitor profile thus will be device-dependent, specific to your monitor.
    Your working space, on the other hand, should be a device-independent profile, such as Adobe RGB or sRGB.  It should NEVER, ever be your monitor profile.
    Your target profile when printing should be device-dependent and specific to the combination of ink, paper and printer model you'll be using.  For the web, create a copy of your image file and convert it to sRGB, then save it as a JPEG as needed.
    Good luck!

  • RGB to CMYK (channels) with PixelConduit plugin

    As I'm unable to submit a user tip yet, I thought I'd share my solution here for anyone looking to simulate CMYK channels in Motion/FCPX.
    PROBLEM
    For some reason you want to convert your RGB source clip to extract individual CMYK (Cyan, Mangenta, Yellow, blacK) channels. For example you'd want to simulate the printing process of a book on a printing press.
    SOLUTION
    Use a free FCPX/Motion 5 plugin caled PixelConduit, a node-based visual effects design system. Install the plugin before launching Motion.
    To extract CMYK channels, I used a (linear) RGB to CMYK formula:
    Black   = Math.min( 1 - Red, 1 - Green, 1 - Blue )
    Cyan    = ( ( 1 - Red )   - Black ) / ( 1 - Black )
    Magenta = ( ( 1 - Green ) - Black ) / ( 1 - Black )
    Yellow  = ( ( 1 - Blue )  - Black ) / ( 1 - Black )
    and translated it to PixelConduit's nodes.
    Clone your source clip four times. Call the clones 'Cyan', 'Magenta', 'Yellow' and 'Black'. Navigate to Library > Filters > Conduit Effect System, choose Conduit and apply it to each clone layer. In Inspector, click 'Show Conduit Editor' and assemble the following node tree for each layer:
    K (black) layer:
    C (cyan), M (magenta) and Y (yellow) layers are identical except the first channel selection:
    So, for M and Y layers change the 'Separate RGBA' node to output the green and blue channel respectively. You can copy/paste the whole node tree between intances of the filter so you don't have to create everything again from scratch.
    You should now have four layers outputting a simulation of C, M, Y and K channel in greyscale. If you'd like to present these channels in colour you'd need to add Colorize filter to each clone layer:
    And finally, if you use Multiply Blend Mode for each clone layer group you'll get a pretty close colour composition to the original source clip! By fine-tuning colour values in Colorize filters and/or tone curves in Conduit you could probably get a perfect conversion.
    Colour values used in Colorize filter:
    Remap White To:
    1, 1, 1 (all)
    Remap Black To:
    0, 0.61, 0.89 (cyan)
    1, 0, 0.5 (magenta)
    1, 0.95, 0 (yellow)
    0, 0, 0 (black)
    That's it! Hope it can help anyone :^)

  • RGB to CMYK to commercial printer

    We are using CS2 InDesign and Photoshop 7 on a PC. I am putting together two
    large books. One insert section of the first book has color photos. I have
    to prepare these color photos for a printer located in China. They want all
    images to be CMYK .tiff.
    I have an assortment of about 100 images from various sources around the
    world, there are .tif, .jpg. .bmp, and .psd. All of them appear to be RGB.
    There are images with: 1) no color profile, 2) sRGB IE60966-2.1, and Adobe
    RGB 1998. Do all images need to have the same RGB color profile before
    converting to CMYK?
    I have been converting all of these to .tif (and using a single dpi/pixel
    resolution for
    all images).
    Do I just select/save as color mode CMYK? Or are there special
    settings/profiles I need to know about. Is there anything special for China?
    The printer's English is not that clear . I was hoping that someone in this
    group would be familiar with RGB to CMYK conversion.
    Also, it appears that the final PDF pages (with embedded Tiff images) will
    be very large. The first complete book for this project (there are two
    books) looks like it will be about 20GB. The second book looks like it could
    be 12GB. Both books together equal about 1,000 pages and have about 1,000
    images. 90% of the images are grayscale. What are the current technologies
    for sending large projects like this to a printer?
    Thanks
    ps, the Photoshop group suggested that I write to this group.

    Tech....
    In the conversions, are you referring to conversions of B&W or color images? I'll assume color for the moment.
    Assuming your monitor is properly calibrated, and assuming you are viewing your color images on your monitor, your conversions should keep "in gamut" colors the same. You will, however, probably see some loss of dynamic range, color, and saturation as you enter CMYK. If the color and dynamic range of the original is all within the destination CMYK gamut, you should see very little, if any, shift. The sad fact is that CMYK on press has limited dynamic range and color, especially compared to a bright monitor. This is generally true, though CMYK can print some colors that lie outside the typical monitor's gamut.
    If you have a brightly colored original in RGB mode, then you should experiment with both perceptual and relative colorimetric rendering to see which one looks best. This is an image by image thing. Relative colorimetric will reproduce all "in gamut colors" as accurately as possible, then will take out of gamut colors and bring them to the closest printable color. This can cause loss of detail and 'piling up of colors' as you near the boundaries of the image's color gamut in the destination CMYK space. Perceptual scales ALL colors and preserves the relationships between colors, which sacrifices color accuracy and saturation, but sometimes looks more natural, especially if there are a LOT of out of gamut colors. Pick whichever ones looks best overall.
    Then, once in CMYK, make minor curves adjustments to tweak if for CMYK. Just be careful not to push it too far, especially in the deep shadows, since you may push beyond the ink limit of the press. For example, if you convert to US Web Coated SWOP v2, the ink limits are set at 300 total. If you drastically darken the shadow areas, you could end up with an ink limit of 320, 330, 350, etc. Knowing the ink limit of the press will help you stay within those limits. Final tweaking in CMYK is usually a good thing.
    How did you determine that the images were dull with too much magenta? Did you print a proof on a calibrated printer, or is this just your screen display? Or is this from a printed image off the press? I have a well calibrated monitor and accurate custom profiles for my inkjet. If I am sending a job to a press that supposedly prints to US Web Coated SWOP, I can proof that file on my inkjet and get a very good match. We need more information to know exactly what you are doing and how you are assessing your images.
    Normally, I do the conversion in Photoshop, using the rendering intent that looks best. Then I tweak the image in CMYK to get it looking its best. I usually have the press profile, but sometimes work with a standard profile if no custom profile is available. I leave the image tagged with my conversion profile. Then, I usually place these images into InDesign, with the profile intact (color management turned on in InDesign). I right click on the placed image to be sure that the profile and rendering intent are set to what I want. Then, I can either supply the InDesign file to the printer, or convert to PDF (leave color unchanged) and make sure that all profiles are included. InDesign should export each image to the PDF properly, along with profile and intent. I have never sent to job to press using Photoshop...only InDesign or Illustrator.
    BTW, rendering intent is only used when getting an image from one color space to another, such as a conversion from RGB to CMYK. You do that, choosing the one that looks the best. Once it is in the destination CMYK space, rendering intent is no longer needed, since all the colors and tones have already been remapped into the final space. Rendering intent is just used to help us handle those out of gamut colors.
    Hope this helps.

  • How to make a script to convert RGB to CMYK as black 100%?

    Hi guy
    my customer sent me a book (144 pages) for print but all of them are RGB and Tiff, she scan them. there are on the page some texts and pictures. The text are R=30 G=30 B=30.I think if I can make a script I will do it very soon to black 100%, but unfortunately I dont know anything to make script 
    anybody can help me ?anybody can make it for me ?

    We need to know some more information.
    1. The book consists of 144 pages, and each page is in fact an RGB image in TIFF format.
        Correct?
        That means, the text is already rasterized, but with low resolution (no more than 300ppi).
        A very bad starting point, in my humble opinion. For offset printing this is not acceptable.
    2. Is the printing process offset printing or by digital printing?
    Nevertheless we may think about a conversion of these images into CMYK K-only (one plate
    per page) . 
    a) Increase contrast until R=G=B=0 for text.
    b) Convert each image into Grayscale, using a so-called Black-Ink-Profile, for instance
        Black-Ink-ISOCoated-v2-eci (can be explained later)
    c) Make empty CMYK image, here for  ISOCoated-v2-eci, and paste the Grayscale into the
        K-channel. All further handling happens as CMYK file for the process ISOCoated-v2-eci.

    All this can be done by an action (I hope so...).
    Much better would be a new start by InDesign with typographical text (K-only vector instead of raster)
    with images in RGB or CMYK, taking into account the intended process.
    Note: Photoshop can deliver vector text, if exported as PDF.

  • Is the win 8 driver for the printer photosmart D7360 rgb or CMYK?

    Hi,
    I will be using Lightroom 4.2 (under win 8 64) and will have the monitor and  printer  (HP Photosmart D7360) calibrated by a colormunki photo.  
     When the printer profile is generated by colormunki, depening on the  actual printer driver, they will be either a RGB or CMYK profile.  Apparently, LR 4.2 will only show printer profiles to use if the driver of the printer is RGB .  So if it was CMYK, I wouldn't be able to use the profile for printing in LR.
    Can anyone please tell me if this printer driver is RGB or CMYK?!
    Any help will be greatly appreciated!
    Regards,
    This question was solved.

    The driver expects RGB data.  The actual color inks in the printer use CMYK but that is handled by the driver, the applications need to send RGB data to the driver.
