PDF ERROR! ICC Based color space contains/ alternate key

Can somebody help me?
When I put in Rip (Agfa Apogee X) a pdf I receive the follow error: ICC Based color space contains/ alternate key.
I don t know where is the problem? There Is a problem with pdf? or it is a problem in my Rip? how can I solve this?

That's pretty odd, because (techncnically) an ICCBased color space must contain an Alternate key, so why complain about it? It certainly seems specific to your RIP, so I would check with Agfa what it means and whether it is a check you can turn off, or if an update is available.

Early and late binding workflows in ICC based color management

Hi all!
I'm a graphic design student at Reading Uni in the UK, and I'm writing my BA dissertation on early and late binding workflows in ICC based color management for print production. I'm intending to write to a graphic designer audience from a designer's point of view. Please do comment here if you have anything to say on this topic, or you can point me to the right direction. I'm also looking for studios where I could conduct my case studies who employ early, medium or late binding workflows.
Thank you.

Will your paper have a title like "Color Management is Fun and Easy" or "The Fiasco of Color Management"?
Notice that in the past week you and I are the only posts on this forum! This is the Color Management forum on Adobe's website. Shouldn't it be really busy?
It appears, that even after nearly ten years I can't remember when color management first began to appear in prepress software), the industry has not embraced color management.
The promise of color management since I can remember was that we could make color documents and not need to know how they would be printed. In other words a late binding workflow; that latest possible, just before making the plates or screens or engravings, etc. After forty hours of reading on the net and testing I am almost positive this is impossible if Illustrator is in the workflow.
Illustrator documents must be either RGB or CMYK not both. So if there are any colors that need to be preserved as CMYK (like 100 K black) you must work in CMYK meaning a mid binding color management workflow. The only thing I can think of is to find, or make, the widest gamut CMYK profile so that the fewest colors are hacked off.
But really how can this all be so messed up? What good reason could Adobe have for doing this? (I can think of several but they all contridict themselves.)
I preped some files the other day that were going to a printer I wasn't familiar with; one of the premium houses here in my area. I called them and asked how they wanted the files sent to them. I was hoping they had profiles for me or would spec some kind of PDF/x document that they would handle. No they wanted the source files and when I asked do you want the images in RGB then said, "No." So I asked which profile did they want me to use to convert to CMYK and the answer was, "What do you mean?" I said which CMYK do you want? The answer was, "The one everybody uses." I used SWOP and sighed.
IF I'M WRONG I would love to hear about it.
Good luck

ICC working color space for the System?

(I posted this in another area but I did not get any replies, so I'm trying here)
Hey, any color management pros out there...
What is the ICC color space of the OS itself? Is it the calibrated monitor profile I'm using?
For example, let's say I'm working in an app. that doesn't use any color management. By default is that color space the app is using by default the ICC profile of the calibrated monitor profile?
I'm specifically wondering in regards to rendering in 3d applications, such as, Lightwave, Strata3d, etc. These apps. don't save ICC profiles with the final rendered files. Are these files essentially in the Monitor space then? This is my guess, and has proven to be so in my tests, but I want to hear what other people think/know...
thanks!
Jeff

What is the ICC color space of the OS itself? Is it
the calibrated monitor profile I'm using?
As Ned said, the OS doesn't have an ICC profile. Profiles describe the properties of image input or output devices. They tell which colour an output device will display when sent a certain RGB value, or which RGB value an input device will return when it sees a certain colour.
Colour space and profile are basically synonymous, a colour space is the range of colours a device can produce or see, as described by its ICC profile.
For example, let's say I'm working in an app. that
doesn't use any color management. By default is that
color space the app is using by default the ICC
profile of the calibrated monitor profile?
No, if the app doesn't use colour management it is oblivious to colour profiles. It will simply throw the RGB values at the output device as they are.
I'm specifically wondering in regards to rendering in
3d applications, such as, Lightwave, Strata3d, etc.
Don't know these two, so can't comment.
These apps. don't save ICC profiles with the final
rendered files. Are these files essentially in the
Monitor space then?
Strictly speaking, no. You will get whatever the monitor or printer make of the RGB values. However, most apps produce/expect RGB values that look reasonably correct on sRGB monitors, for historical reasons. Hence, even on systems without colour management (or when using apps that aren't CM aware) you can calibrate your monitor to mimick sRGB behaviour (using the on-screen menu) and get reasonable results. Most good CRT monitors come pretty close to sRGB out of the box.

Separation color space - get alternate color (function of type 0)

Hello,
I'm trying to retrieve the alternate color value of a spot color which has a function of type 0. Actually I just want to retrieve the result of the function when the tint is 1.0.
How can I do that?
Thanks in advance,
Joe

Right Leonard.
The function is PDApplyFunction().
Thanks,
Joe

PDF in CMYK color space?

I'm working on the most recent version of Pages from iWork 2008 running on the most recent version of Leopard, and I have to create a PDF in the CMYK color space for publication, but I do not have Acrobat Distiller.
Is it possible to create a CMYK PDF with ColorSync filters? I have tried using the "Generate PDF-X/3" filter, with "Generic CMYK" as the target profile and transparency flattening, but the printer still says that my PDF is in the RGB color space. If not, is there any other way to create a CMYK PDF from Pages or to convert a RGB PDF or PostScript file to CMYK using ColorSync Utility? Are there any alternatives without purchasing Adobe Acrobat? What about if I first convert images to the CMYK color space before importing them to Pages?
I have seen similar questions posted elsewhere, but I can't find a straight answer anywhere.

1. Obtain the ICC profile from the printer for his output device.
Correct. Either the shop printing condition or an ISO 12647 printing condition to which the shop can configure and calibrate the printing condition it is selling you. If the latter, you can get default ICC printer profiles for standard printing conditions at www.eci.org.
2. Create a filter in ColorSync Utility for generating PDF/X-3 documents with the ICC profile as the output intent (besides flattening the transparency and applying an appropriate resolution).
Correct.
3. Print to PDF in Pages.
Incorrect.
Your PDF/X-3 filter will become available in the system dialog for File > Print > Save as PDF. In saving as PDF you pick your PDF/X-3 filter as the template for the save process.
4. Use ColorSync Utility to modify the resulting PDF with the filter I created in ColorSync Utility.
(or 3-4. Print directly to PDF through the filter from Pages)
Your second step to combine 3 and 4 is correct, your first step 4 to save to disk and then postprocess in the ColorSync utility is incorrect.
5. Send this PDF/X-3 to the printer.
Correct.
It seems that no hard conversion from RGB to CMYK should be necessary if I take these steps, is that correct?
Correct.
If I send the printer a PDF in the RGB color space, should it cause problems for him to convert the PDF himself to the color space of his output device?
No.
You create three channel RGB images in the RGB colourant data model (it's just a model, it is not a colour space which a size and a shape of the gamut).
You save your colourants to disk in TIFF or PDF format with the ICC profile for the capture colour space (e.g. the ICC profile for your specific scanner with a Kodak EktaChrome IT8) or correction colour space (e.g. Joseph Holmes' RGB working space for EktaChrome). This ICC profile is the _colour space_ that you can view in the ColorSync Utility as a specific size and shape of gamut. The colour space determines what colours the colourants in your TIFF or PDF image should reproduce on different colour devices.
You now have a pagination with photographic objects in three component RGB, and you know what colours those colourants are supposed to reproduce. You then include the production profile for the printing condition. Your source profiles must match to this destination profile in the matching session, so all your photographs get converted to the SAME ink limit, the SAME graybalance and so forth. This unifies the inking behaviour and the colour formation for your printing.
If you imagine that in your pagination you place photographs which are manually converted into four component CMYK using a different ink limit, a different graybalance and so forth then you have not unified your inking behavour and colour formation for the printing process. This is IDIOTIC because the only way to correct in this case is to change the calibration of the individual inking zones on the offset press - increasing or decreasing the cyan, magenta, yellow or black for that zone.
It used to be that lithography on the press was the only way to work. This was in the days of EPS and EPS DCS, and before that in the days of photographic printing masters pasted together manually piece by piece to make the printing planes. Nobody in their right mind works that way today.

What color space as base in a brand guide?

What color space forms the base of a color brand guide? How do you start in terms of color spesifications? When I look at most guides it seems that Pantone is always the base, then CMYK, then RGB and Hex? Is RGB and Hex always gonna be a dithered version of the CMYK values or is it best practise to hand pick each one to make them look as close to the CMYK as possible? Is Pantone always mentioned first in the list because that's where the designer started?
Also, is best practise to mimmick the CMYK and Pantone colors so that the RGB and hex values look like them? Seems to me that most brand guides / visual manuals are made firstly for print, then they add the screen based color spaces.
In the enclosed example I also observe that the complete values are not always listed, in many cases the Y and K is missing in the CMYK values, does that mean it doesn't contain any black, or is it simply meaning zero? It rarerly occurs with the other color spaces.

For web, email and screen in general it should always be sRGB. Then you can be fairly certain that it will display correctly (more or less) in any scenario. sRGB wil also work for print (inkjet), it's just that many colors that can be printed are out of sRGB gamut, so it's a restriction that doesn't need to be there. sRGB is a small color space that can't reproduce very saturated colors - they're just clipped. So it's better to start with a larger space like Adobe RGB or even ProPhoto.
For editing purposes you want a large color space simply to have headroom and not hit the wall at every move. The final destination may well be a smaller space, like a printer profile. The software then converts to that destination profile as it goes to the printer. You can soft proof to the printer profile to get an impression of how the final result will look.
You can print directly from InDesign, but the typical InDesign workflow is to export a finished PDF. That is where you specify a final destination profile for the whole document, whether a certain CMYK profile for offset press, or an RGB profile for screen. So you have your master InDesign file, and output PDFs for each destination. The InDesign file can contain placed RGB images in any color space, while text and graphic elements are CMYK. Then everything is converted in one go at export.
You should always go through the PDF Export dialog carefully. Use the presets, but don't automatically accept defaults. For specific purposes, ask here or in the InDesign forum, where they deal with this all the time.
For screen, under "Output" use convert to destination, sRGB, include profile. Under "Compression", things aren't as obvious as they used to be (downsample to 96 or 100 ppi), because of the new retina displays that can benefit from a higher resolution. I hold my judgement on this one.

InDesign exporting to PDF - .eps and .ai color issue

I've been reviewing a lot of help forums and have played with a lot of solutions and can't seem to fix this one.
With no updates or changes to my usual settings I've noticed an issue with my company logo when I export to PDF from InDesign CS6. Once I open the PDF all images and color spaces look fine, but the logo is muted, as if I set the opacity to 60-70% before exporting.
It happens with both EPS and AI files. It does NOT happen when I place the logo as a JPEG, but I need transparency and quality on these PDFs. Don't say PNG please, same issue with quality.
I don't understand how it changed when I changed nothing.
Any guidance would be appreciated, and I know I couldn't have possiblty provide a complete set of variables, so let me know wheat else would be helpful.

Thanks for both your responses. It appears that everythign in the original logo file and InDesign file are accurately set up. I've explored any back corners to see if something is off, but it all reads the same space/model/mode.
I've inserted an exported image to show the issue. The file formats from top to bottom is: AI, EPS, JPEG, PNG
Any other ideas?

Image in PDF error - Expected end of color space

Hi friends,
I am displaying a PDF file in an webdynpro application. The contents are coming from the output of a RFC. The pdf file contains an image. While I am running the Webdynpro application the image is not coming. An error popup <b>"Expected end of color space"</b> is generated. But the texts of pdf file is coming properly.
Please help.
With regards,

Error "Expected end of color space" when opening converted OTF - PDF.

Hi experts,
I need help. I'm converting from otf to pdf and it works fine. However when i tried putting a bitmap 256 color to the smartform and generate pdf with CONVERT_OTF FM the pdf result in an error "Expected end of color space" when opening the document and it goes blank.
Can anyone tell why ?
Thanks,
Felix

Hi Peter,
I can open it with another acrobat version. However, the image is not displayed. Do you know why?
Thanks

"Unsupported Color Space" error trying to open b/w PDF in PS

This glitch has occured periodically in every version of PS I've ever used. I'm sick of getting it. Let me emphasize" I'm working with a b/w all-text image scanned into a PDF using the "text" setting on my scanner. In past attempts with Adobe tech support to get this fixed, it ends up having something to do with a glitch in PS programming, which gets fixed after an hour and a half of being treated like an airhead by the support tech and finally going into the secret settings area of PS and fixing it.

I did some tests on that image (Color Space: Indexed Device Gray) in Acrobat Pro.
If you want to open it in PhotoShop you could convert the whole PDF to RGB.
There is a Single Fix Up in the Preflight section of Acrobat Pro for this.
See screen shot of Acrobat Pro 9 here (in X or XI this feature is also available):
After using that fix up and saving the PDF to a new name, the TouchUp Object tool can use PhotoShop to open the image as an Indexed 8Bit Channel image in PhotoShop.
You can now convert to Grayscale in PhotoShop if you want…

What's the word on this? I am still having the same issue. This is very problematic for many pdfs on many websites! Can someone from Adobe please answer this???

Invalid Color Space error after update Reader to 9.3.3

After updating Adobe Reader to 9.3.3 I run into the Invalid Color Space error when trying to open a PDF file created with CorelDraw 12 in the format PDF/X-1A. This format needed by a printing office to print the file. The strange thing is that Reader opens older PDF files exported from CorelDraw in thsi format normally without the error message.
It happens only with PDF exports made after the Reader update. CorelDraw settings are as previously used.
Exports in other formats, other than PDF/x-1, X-1A and X-3 open normally. How to solve this??

any suggestions?

New ICC v4 sRGB Color Space May Prevent Clipping Converting From ProPhoto RGB

Just discovered and tried out this new sRGB color space downloaded from this page:
http://www.color.org/srgbprofiles.xalter
Here's a cropped demo with histograms of a raw image I've been working on in ProPhotoRGB in ACR 3.7 and CS2:
http://www.flickr.com/photos/26078880@N02/2874068887/sizes/o/
Please disregard the PRMG name in the demo. I got confused as to which was which on that site and thought that this version of sRGB was a PRMG=(Perceptual Reference Medium Gamut) profile. It's called sRGB_v4_ICC_preference.icc.
Note the different color shifts using the Perceptual intent and unchecking Black Point Compensation=(BPC). Neat little features embedded in this profile, but not sure about how it renders certain colors close to clipping in the shadows. That site doesn't recommend mixed use of ICC v4 with v2 color spaces and output device profiles but I did it anyway just to see what it does.
Who knows this may be the equivalent of handing scissors to children, but I'm just one of those curious children and thought I'ld share anyway.

I'll try to respond to a few items above.
The digital values in a Pro Photo RGB file should generally be the same as for a ROMM RGB file. The exception is that all possible Pro Photo RGB values are "legal" but not all ROMM RGB values are "legal." ISO 22028-2 restricts the legal ROMM values to those with PCS LAB values between 0 and 100 L* and -128 to +128 a* and b*.
There is no enforcement if you use the illegal values in a ROMM file but as some of these values do not represent possible colors this is not advisable. I think it is good practice to try to stay mostly inside the ICC v4 PRM gamut with Pro Photo/ROMM images. You can check this using the gamut warning profile on the ICC site.
If you have a Pro Photo RGB image you should just assign the ROMM profile to it. Converting to ROMM RGB should not change anything in the ideal sense but there is the possibility to introduce rounding errors and mismatch black points.
The main difference between the Pro Photo RGB profile and the ROMM RGB profile is the former includes black scaling to zero (as is common with v2 color space and display profiles) and the latter does not (as is required with v4 profiles).
In the duck picture, the reason for the difference is the ROMM profile black is at L*=3 so this is where the lowest blacks land when converting MRC to v2 sRGB (which has the sRGB blacks scaled to L*=0). In this case leaving BPC off is analogous to turning on "Simulate Black Ink" in Photoshop Proof Setup.
All the ACR color space choices are v2 profiles with black scaling. If you want a v4 profile embedded you have to assign it (if you have a corresponding v4 profile) or convert to it.
Both the sRGB and PRM gamuts fit within the ROMM RGB legal encoding range, but if you use a v2 profile with black scaling you should always turn on BPC when combining with a v4 profile. Otherwise the v4 profile will think the v2 profile represents a device with an infinite dynamic range. When BPC is on the Color Engine scales the black point of the source profile to the black point of the destination profile.
The sRGB gamut extends outside the PRM gamut in some places, and the PRM gamut extends outside the sRGB gamut in other places. If you convert using a colorimetric intent in either direction some of the gamut will be clipped. The purpose of the sRGB v4 perceptual transforms is to minimize clipping in both directions.
I can't do this justice here but basically scene-referred images are encodings of the scene colors and output-referred images are encodings of the picture colors on some medium for which the picture colors have been optimized. You can make a scene-referred image by setting the ACR sliders (except the white balance sliders) to zero and the curves tab to linear. You make an output-referred image when you adjust the sliders to non-zero values to make a nice picture as viewed on some medium. For example you might adjust the sliders differently to get the best results printing colorimetrically on glossy photo paper vs. on plain office paper.
Often an important part of the transform to output-referred includes a midtone contrast and saturation boost. While there will likely be some highlight and may be some shadow compression, it is misleading to think of this transform only as a compression to some output medium dynamic range. In some cases the output medium dynamic range is larger than that of the scene.
Usually the transform to output-referred is more complicated than a simple gamma function.
Regardless of the image state (scene-referred or output-referred) the sRGB, Adobe RGB, or Pro Photo RGB nonlinearities will be applied to create the image data that you open into Photoshop.
We are working in the ICC to prepare more information for posting on this topic.

Why Invalid Color Space Error?

Hi Everyone,
I am receiving numerous "invalid color space" errors when viewing PDF files in Acrobat Reader (v 11.0.10) on Windows 8, but have not received similar messages when using Acrobat Reader (v 11.0.10) on Mac OSX 10.9.5. I will outline our environment and workflow below.
The PDF file is created via the export of an InDesign CC 2014 document. No errors show up on the preflight panel, and no warnings show up upon export. The file can be opened fine in the Mac environment with both Acrobat Pro 11.0.10 and Acrobat Reader 11.0.10. I can navigate through pages, print, and add comments in both applications.
When this same file is opened on Windows 8 it initially loads, navigates pages, and will allow a few comments to be inserted before showing an "invalid color space" error. If the error occurs during commenting, the comment will disappear, and I am no longer able to scroll through any other pages since the error reappears.
I would think that if it was file corruption the problems would be on both Mac and Windows. Any suggestions would be extremely helpful as all of my searches point to a non-Adobe product (as either the document source or PDF generator) as the culprit with this error.
Thank you!

(2) Doubleclick the msicuu2.exe file and follow the prompts to install the Windows Installer CleanUp utility. (If you're on a Windows Vista or Windows 7 system and you get a Code 800A0046 error message when doubleclicking the msicuu2.exe file, try instead right-clicking on the msicuu2.exe file and selecting "Run as administrator".)
(3) In your Start menu click All Programs and then click Windows Install Clean Up. The Windows Installer CleanUp utility window appears, listing software that is currently installed on your computer.
(4) In the list of programs that appears in CleanUp, select any iTunes entries and click "Remove", as per the following screenshot:
(5) Quit out of CleanUp, restart the PC and try another iTunes install. Does it go through properly this time?
