Why Illustrator CS6 convert CMYK to RGB when I do "Add to switches" in Color menu?

1. Open Color menu and work with color in CMYK.
2. Do "Add to switches" (or "Создать новый образец" in Russian)
3. See that new color was added like RGB not like CMYK.
4. When I open parameters it show me HSB options.
5. I switch it to CMYK and push OK
6. Nothing cange - RGB in name and HSB in options.
Look like it's error.

I found what change it to normal way, but logicaly it's should not be a reason for autoconvert colors. If I choose CMYK and want add CMYK color it should be CMYK (in name minimum) and not RGB.
File->Documents Colors->CMYK(should be, but RGB was)
Right now options open like CMYK, not HSB. But if I want color in RGB it added like CMYK. Options like in CMYK, not HSB, again. Still look like error.

How to convert CMYK to RGB programmatically.

Hi,
I have a CMYK colorspace in indesign, i want to convert that as RGB color space, I got some codes, but I am getting incorrect data.
Some of the codes which I tried are given below
        double cyan = 35.0;
        double magenta = 29.0;
        double yellow = 0.0;
        double black = 16.0;
        cyan = Math.min(255, cyan + black); //black is from K
        magenta = Math.min(255, magenta + black);
        yellow = Math.min(255, yellow + black);
        l_res[0] = 255 - cyan;
        l_res[1] = 255 - magenta;
        l_res[2] = 255 - yellow;
@Override
    public float[] toRGB(float[] p_colorvalue) {
        float[] l_res = {0,0,0};
        if (p_colorvalue.length >= 4)
            float l_black = (float)1.0 - p_colorvalue[3];
            l_res[0] = l_black * ((float)1.0 - p_colorvalue[0]);
            l_res[1] = l_black * ((float)1.0 - p_colorvalue[1]);
            l_res[2] = l_black * ((float)1.0 - p_colorvalue[2]);
        return (l_res);
The values are C=35, M = 29, Y = 0, K = 16 in CMYK color space and the correct RGB values are R = 142, G = 148, B = 186.
In adobe indesign, using swatches we can change the mode to CMYK or to RGB.
But I want to do that programmatically, Can I get any algorithm to convert CMYK to RGB which will give the correct RGB values.
And one more question, if the alpha value for RGB is 1 then what will be the alpha value for CMYK?
Can anyone help me to solve these issues... Thanks in advance.

All you have to do is loop thru the swatches and change the space to RGB. Below is an AppleScript, but it shouldn't be too difficult to come up with the equivalent JavaScript. Your document's assigned RGB space will determine what RGB space the CMYK converts to, so if you are looking for sRGB, then Edit>Assign Profiles...>Assign Profile: sRGB
tell application "Adobe InDesign CS3"
tell document 1
repeat with a from 1 to count of every swatch
try
set space of color a to RGB
end try
end repeat
display dialog "All swatches have been converted to RGB color"
end tell
end tell

Why do Adobe Color CC and Indesign CC not convert CMYK to RGB the same?

I recently used Adobe Color CC to create a color theme that will be used for both print and web. I created the theme with approved CMYK values with the intent of saving the .ASE file to be imported into other CC apps. Corresponding RGB, Hex, Lab and HSB values are automatically created. Of course, we are using CMYK for print and RGB for web
A coworker had separately created the same exact CMYK theme in InDesign CC, and created RGB values from the same exact CMYK values I had used in Adobe Color.
The InDesign RGB values are quite different from the Adobe Color values.
Anyone know why the values are not the same, and moreover, which CMYK to RGB conversion values may be relied upon for accuracy?
EDIT: I guess the real question should be, What are the color management settings built-in to Adobe Color CC, and can they be duplicated in desktop Adobe CC applications?
Thanks very much

It's working for me (Web, PS, AE, ID, FL; not available in the Color Themes panel in Ai). Please click the triangle next to the color space to expand and view more data.

Convert CMYK to RGB for MS Word?

Greetings! I've designed a logo for a client using Illustrator CS6. There is the 4-color version in CMYK .eps as well as 1-color, 2-color, and KO versions. Everything looks and acts as it should and will no doubt be perfect for offset printing (my main area of experience). However, once delivered to the client they were anxious to put them into use and immediately dropped the 4-color version into a word document and made a pdf for email distribution. When I received it I had to groan, the colors had shifted to the obscene.
My guess is that what the client needs is a set of the logos that are converted to RGB. I'm also thinking that since the logos might be re-sized for various uses, keeping the art in the .eps format (as opposed to a raster format) makes sense. Is that true?
And,
Is there an easy way to convert the original CMYK eps files to RGB within Illustrator?
I'm wide open to suggestions for best practices regarding artwork for use in MS Office applications.
Thanks!
Tim

Since you're already familiar with a print workflow, your profiles are probably correct for this conversion. The only caveat would be how Word deals with color. I don't use Word, so I have no idea about that. Best practice would be to learn how your client is going to use the files you supply, and test each application.

How do you Convert CMYK to RGB

I have a project that I need to convert all of the AI files from CMYK to RGB. This use to be very simple back-in-the-day by just choosing Filter > Convert to RGB. I know about Document Color Mode and Convert to RGB.
When I select all of the objects and choose RGB under Document Color Mode, I still see CMYK plates when I preflight the PDF. Depending on what the Document Color Mode is set on, I either have Convert to RGB grayed out or always available. The resulting file show up as CMYK in both Quark and ID along with CMYK plates when I preflight the PDF.
What am I missing here?

Can you be more specific? Which option are you interested in?

Convert cmyk to rgb in acrobat 7

Good morning,
I have a question about converting color spaces using Acrobat 7 Professional and Pitstop Pro.
I have some CMYK PDFs used for magazine printing that I need to convert to a 144 DPI RGB version for a digital edition.
I know most folks are concerned with RGB to CMYK but I need to do it in reverse...
If I do a Convert Color in Acrobat CMYK to RGB it looks a lot better than if I do it using an Action List command to Convert to RGB in Pitstop.
The Pitstop ones look almost posterized, way darker with significant color shifts
I would have thought Pitstop would use the Acrobat color engine to do the transformation to RGB but it seeems it knid of does it's own thing.
I do have sRGB selected in my Color Management Prefs in Acrobat.
It would be nice to make this RGB second version PDF with Pitstop and Distiller on our server so it runs more automated, less manual intervention...
thanks for any advice you have,
Pat

I think I stumbled across the solution... there are separate Color Management Preference controls for Pitstop.
I selected sRGB instead of the Enfocus Default RGB.

Illustrator CS6 crashes ,on my mac, when I use the gradient tool. Any help out there?

My illustrator cs6 crashes when I use the gradient tool. I'm using a mac with mac os 10.9.3.
This driving me mad... any help out there?

mr.roo,
The following is a general list of things you may try when the issue is not in a specific file (you may have tried/done some of them already); 1) and 2) are the easy ones for temporary strangenesses, and 3) and 4) are specifically aimed at possibly corrupt preferences); 5) is a list in itself, and 6) is the last resort.
1) Close down Illy and open again;
2) Restart the computer (you may do that up to 3 times);
3) Close down Illy and press Ctrl+Alt+Shift/Cmd+Option+Shift during startup (easy but irreversible);
4) Move the folder (follow the link with that name) with Illy closed (more tedious but also more thorough and reversible);
5) Look through and try out the relevant among the Other options (follow the link with that name, Item 7) is a list of usual suspects among other applications that may disturb and confuse Illy, Item 15) applies to CC, CS6, and maybe CS5);
Even more seriously, you may:
6) Uninstall, run the Cleaner Tool (if you have CS3/CS4/CS5/CS6/CC), and reinstall.

When I open Add-ons, from the Tools menu, I get an unresponsive script error: file:///C:/Program%20Files/Mozilla%20Firefox/components/nsExtensionManager.js:623.

When I try to click on Add-ons, from the Tools menu, I get this error message of an unresponsive script: file:///C:/Program%20Files/Mozilla%20Firefox/components/nsExtensionManager.js:623. This is to say the least about the unresponsive script errors at other times. However, at all times, it won't go away - even by clicking on the 'stop script' option; even with checking the 'don't ask again' option. I've cleared the cookies and history as best I could, but it appears that there is some sort of conflict. How can I resolve this? Kevin: [email protected] Thank you.

This is typically caused by a problem with the Personas Plus 1.6 add-on and it conflicting with the Google toolbar.
Try disabling the Personas Plus add-on. To do this open the add-ons manager by selecting the Tools menu, then Add-ons. In the list of installed extensions click on Personas Plus, then click on either disable or uninstall.
If you can not access the add-ons manager, follow the instructions in the [[safe mode]] article to start Firefox in safe mode. You should then be able to disable or uninstall Personas Plus. You can find more information on this procedure in the [[Troubleshooting extensions and themes]] article.

Illustrator CS6 - Converting to a 1 Colour Job

I currently use Illustrator CS3 to process an SVG file into an EPS file via a particular method - I'm having a problem duplicating the results using CS6 and suspect it is to do with the Pantone + issue. If anyone could shed any light on this I would be most grateful. Here's the thing:
The SVG vector file originates from custom online-based code. The vector in question has maximum and minimum ink density information coded into it and these change from job to job. The SVG opens up as an RGB vector in Illustrator with numerous shades of grey as different colours. To convert this to a 1 colour job and regain the desired ink density information in CS3 I do this:
Select all. Edit / Edit colours / Recolour with Preset / 1 colour job. Then I choose the Pantone Solid Coated library. In this dialogue box I select 'Tint' as the mode for the colour adjustment sliders, and input the maximum ink density information for the file. I then click OK and hey presto, the vector is now a single spot colour with the ink density information faithfully correct as per the data input to make the original SVG file, created online. For example, if the max and min ink density info was 30% and 10%, the vector file now has exactly that.
(At this stage it doesn't matter what spot colour it is, just that it is 1 spot colour and the info is correct).
Problem is with CS6, when I input 30% and click OK, the resulting vector has a maximum of 100% and a minimum of 40% - nothing like what I've asked of it. The only difference I can see is that CS6 uses Pantone +, and CS3 Pantone. I've already tried adding the old Pantone solid coated.acb file into CS6 Presets and accessing that library, but still the same problem. Why is it doing this? What am I missing?
For now I'll stick with CS3, but any insight or clarification would be a great help. Many thanks.

Try contacting Pantone.com/support and asking this question there. I am sorry, but I have no answers for you. I'd also try contacting adobe.com/support and ask them the same question. I find it troubling that so many users are having workflow setbacks using CS6. Let me know if you get an answer, I'm interested to learn why adobe has created such a nightmare.

How does PDF convert CMYK to RGB?

Hi
I want to know the formula that PDF uses to convert DeviceCMYK to DeviceRGB values. It seems that Photoshop and PDF uses the same forula, where the other Programs use the "normal" formula, which can be found on the internet and some online RGB to CMYK calculators.
Where can I get this formula?

As recommended in the PDF Standard (ISO 32000), all color conversion is done using ICC-based color conversion. The "red book" algorithms are clearly marked as deprecated in ISO 32000-1.

Converting cmyk to rgb

I have about 200 .psd files with a customized CMYK profile (used for press) that I have covert to Adobe RGB (1998). Amazon recommends this for Look Inside, because CMYK fails when they OCR the PDFs.
The only way I know to do this is one .psd at a time. Is there a way to streamline this in Bridge or PS other than using keystroke shortcuts (which I alrady do)?
Thanks in advamce.
Toni

Outstanding. Thank you so much! Ninty files done in a flash, 150 to go. Now if I could just get something simialr to work on my 300+ Illustator files!
Cheers,

Applescript ObjC convert CMYK to RGB

I've got a routine that gets the color from a color well. Trouble is, it's sometimes in CMYK instead of RGB, which I need.
I've tried all sorts of things, but constantly get the error...

Illustrator CS6 : Some layers are missing when exporting files

Hello all,
I'm trying to export my project for use in Adobe Director 11, and I'm encountering a problem with the export feature that I believe to be a legit bug, and seeing from the amount of threads related with my problem, I believe some other people have encountered it too. I provided some pics for an easier explanation.
So.. firstly, the image below is the screenshot of my project in AI, combination of paths, mask and pictures.
Next I'm trying to export it to PNG without artboard & use transparent background. Notice that the export preview still shows the image that I expect as the export result.
Below is the exported image.
As you can see, some part of the project is 'missing' in the exported files. The problem still occurred no matter I exported it to png, jpg, even psd. Changing the export resolution and anti-aliasing setting doesn't help.
I've encountered the same problem with different project for at least 5 times in like the last 8 months, and I find that each time I encountered the problem, it can only be temporary fixed by some specific procedures and sometimes each problem won't work with the same workaround. For example, one time I can properly export the project after I copy & paste the 'missing' layers and delete the original layers, in other time I have to select the 'missing' layers, move it a little and then move them back to its first location in order to export it properly. I also find that copying the entire layer that I want to export to a new document works a few times. I can't remember some other solutions I have tried that works, but if these solutions doesn't work anymore, I have to find another and it's pretty confusing since it happen to be 'random'.
Since I believe that this happen to be a program bug, I would love if one of those Adobe guy read this post and direct the problem directly to the AI team or something so it can be fixed in the next updates. Until then, anyone ever experienced the problem? What did you guys do to 'fix' the problem?
Many thanks for people who help me here.
P.S. As I'm writing the last part, exporting my current project to PNG with transparent background seems to be working properly after I tried to export to PNG with white as the background color, I dunno why, but it works now. I still want to know other workarounds to 'fix' the problem though, that could be helpful for other people out there.

The first thing I was going to ask was if you saved as PDF earlier, but then I noticed you specifically said not in your first post. I have lost two layered high res images in the last couple of months due to getting mixed up after exporting to PDF for print. I still don't know how it happened, but I have to assume user error.
I also note you are using CS6 which has the JDI features, so saving as a JPG would not have flaterened the layers. I almost never use TIFF as it feels better to use PSD as it is the native format, and it limits the opertunity to mess up. So I am not being very helpful. If you absolutely didn't save out as JPG or PFD or similar, then you have to start thinking bug, but I have never heard of this happening outside of user error.
[EDIT] Whoops. Overlap. I called for my breakfast half way through typing my answer. Glad you got it fixed

Why is CS6 converting my files to DICOM files? Won't let me save as jpeg. Where do I change this?

Raw files open into ACR without a hitch, but when saving from PS, each file is 'saved as' a .dcm file - even when I choose jpeg in the format area. Anyone know where to change this default? thanks!!!

It's ALWAYS happened in prior releases that you cannot mix plug-ins from one version of Photoshop with another without unpleasant consequences. You need to get your story straight.
All you need to do is isolate the third-party plug-ins you want to use into their OWN separate folder, THEN you can use the Extra Plug-ins Folder settings to make each version of Photoshop aware of them.
And take heart - you'll notice that Photoshop CS6 has moved all ITS plug-ins out of the plug-ins folder to some other place. When you upgrade to Photoshop CS7, if you haven't heeded my advice you won't have this problem anyway.
