Convert to RGB Color Mode (Windows XP/CS4)

It appears I have to change an image from indexed color mode to RGB mode. Can someone please tell me how to do that? Thanks!

Image > Mode > …
But if a photograph is "Indexed Color" it is likely not very good quality and you might want to try getting the proper source material.

My illustrator CS6 crashes when i try to open an AI file with RGB color mode

My illustrator CS6 crashes when i try to open an AI file with RGB color mode. I worked on this file yesterday and changed it to RGB mode. Today i tried to open the file again but illustrator won't open it and crashes. It does work when i want to open a file with CMYK color mode.
Anyone know how to fix this ?

Have you tried trashing the prefs?

Is it possible to export png use RGB color mode

hi,guys.
I use the following code to export the png , now is it possible to export png use RGB color mode?
Or is it possible to set it when export it
var pngOpts = new ExportOptionsSaveForWeb;
                            pngOpts.format = SaveDocumentType.PNG;
                            pngOpts.PNG8 = false;
                            pngOpts.transparency = true;
                            pngOpts.interlaced = false;
                            pngOpts.quality = 80;
                doc.exportDocument(saveFile, ExportType.SAVEFORWEB, pngOpts);

I use the following and do get png24-files.
////// function to png //////
function savePNG (myDocument, docPath, basename, theSuffix) {
// weboptions;
var webOptions = new ExportOptionsSaveForWeb();
webOptions.format = SaveDocumentType.PNG;
webOptions.PNG8 = false;
webOptions.transparency = true;
webOptions.interlaced = 0;
webOptions.includeProfile = false;
webOptions.optimized = true;
myDocument.exportDocument(new File(docPath+"/"+basename+theSuffix+".png"), ExportType.SAVEFORWEB, webOptions);

Convert 2 RGB colors to CMYK in AI CS5

Hi,
I created a logo in RGB and now I need to have business cards printed and the file has to be in CMYK. If I change the color mode to CMYK, the colors fade of course and don't match the RGB colors. I only have two colors in the logo:
#CCFFFF
R = 204
G = 255
B = 255
#0000CC
R = 0
B = 0
G = 204
The printer told me to use a CMYK color pantone guide book. I am using AI CS5 and was able to locate the Pantone guidebooks that come with the program. However, I am unsure which Pantone guide I am supposed to use since there are several. What would be the best way for me to recreate the logo in CMYK mode keeping in mind that I want the two colors to match the RGB colors listed above? I just googled CCFFFF and discovered that in CMYK it is 20,0,0,0 and # 0000CC = CMYK 100,100, 0, 20). The color doesn't match exactly in AI, but I am assuming that this is the exact match for the printers? Please correct me if I am wrong.
Any assistance is greatly appreciated.
Thanks!

You're working backwards, typically colors would be chosen from the Pantone Spot Color guides and then converted to CMYK and finally RGB for web work. It appears you've got a very light Blue ( 20% C ) and a very dark Purple ( 100%C, 100%M, 20%K ). The closest Pantone to the light Blue is 628C ( 19C, 6Y ); and 662 ( 100C, 72M, 18K ) for the Purple ( these are older PMS numbers; not the "+" series ). I'm showing you these numbers so that you'll have an idea of their relationship to Spot colors. You have not mentioned what type of paper these cards will be printed on...coated or uncoated. That makes a big difference, too. Most of the time, stationery items are printed on uncoated paper using Pantone ( or other ) Spot Colors. I often see coated, glossy business cards similar to those you would buy from VistaPrint online. The danger is trying to match the coated paper color on a uncoated sheet in the future. If you are planning for coated paper, the 20% and 100-100-20 combo will be OK ( although the 100C-100M-20K is a little on the dark side...almost Black ). The dark Purple is a little troublesome because it may look good on the monitor, but you might not like the printed version ( too dark ). If I were you I'd venture into a local print shop and ask to see their Spot Color guide for the paper you plan on using. It's best to use your visual sense this way and then apply the CMYK equivalents in your file. Good luck.

Which color mode in psd cs4 is best to use for 2-color project, grayscale or cmyk?

The project is a photo montage. It was 4-color, now must become 2 colors.
So I've changed each of the original 4-color photos (jpg and eps) into separate psd files (as grayscale/duotone/montage-and assigned it One pantone color)
In a new psd "montage" file, I plan to place each photo on its own layer, adjust tints, transparency, etc, to create one new montage/flattened.
I'm not sure which color mode is best when setting up this new file, CMYK or grayscale?
Once the PS doc is done, the job will be saved as a PDF for 2-color printing.
I want to insure the 2 pantone colors separate properly at press.
any advise how how to best achieve this?

Yes it is possible in InDesign. You will have to judge whether you feel more proficient in doing something new in Photoshop or in InDesign.
If you restrict this to being done in Photoshop, you just need to change the color mode to duotone and export the PDF file with the 'high quality print' profile or similar. Some other PDF settings may convert your duotone to a regular CMYK or RGB image.

Consistent RGB Color Values with Photoshop CS4: An Impossibility??

What I want is very simple: I want the Photoshop files I am working on and the rendered PNGs in my browser to have the same color values. I don't care if my web images look the same color on other screens or anything like that. All I want is for the screenshots of PNGs my web browser to match the color values I have used in Photoshop. I've had it up to here with color shiftsthis did not used to be an issue in CS3.
Moreover, if I save a file on my Mac, and a color value is, say, #cf4640, I want someone who opens the file on a Windows box to get the same color value for that pixel. Ditto for the images I have saved for the webI want the RGB values to be consistent. This does not seem like too much to ask, does it?
Right now, I have turned all color management policies set to Off, working spaces are all set to Generics, and documents are set to "Don't Color Manage"my Windows colleagues also have these same settings. This used to work as expected in CS3we all got the same color values on the same files, and colors didn't shift when viewed in a browser.
Once again, I don't care if the colors *look* the same from platform to platform or screen to screen. I just want consistent RGB values.
Color management has never caused me anything but headachesleave my colors alone, Photoshop! I really really wish there was a "Work Like Photoshop 4" setting for color management.
Does anyone have any ideas how I might solve my problems?
Thanks very much.
Oh, and, incidentally, I was originally thinking of calling Adobe about this; how foolish of me. I looked into it, and can I just say how fantastic it is that you have to pay extra money for actual first-party tech support on a $700 piece of software?

The sounds/language analogy isn't really relevant to this problem, because it suggests transforming between two entirely different media. One medium: the medium of sound information, to another entirely different medium: the medium of thoughts and meanings. That's something that simply can't be done without an intermediate translation. That's not the case with color transforms in the RGB space, where it's just a matter of taking RGB values and pushing them through a matrix to produce other RGB values. That's the process that messes everyone up and creates all the confusing color output, and frankly it's an unnecessary process. Your assertion that the values in a source image have no meaning without an associated profile isn't entirely true. What if those source values were simply pushed directly though to the display? After all, a display simply renders 8 bits of R, 8 bits of G, and 8 bits of B for each pixel.
I think the original poster has some very valid concerns. Sometimes we just want to set some color values, and know that everybody's display, on every platform, will render those color values the same way. As he said, they may not look identical to the eye, but the values going through that DVI cable will be setting that pixel to the same 24-bit value no matter what. That's how things would be if there were no such thing as color management. That's how things used to be long ago, and in many ways the world of color was far more predictable and less confusing back then.
Here's my vision for a perfect world: color management doesn't exist in the RGB space. None. No such thing. Source RGB values in images get pushed right through to the display. The onus is on the display manufacturers to produce hardware that renders those values as consistently as possible. In the world of print, sure- color management is incredibly useful. But if only we could go back in time and keep color profiles out of our RGB, I believe we'd be much better off today.

Automatically convert from RGB to CMYK color mode

I have over 900 barcodes provided in EPS format. When I open them in illustrator, they are coming in as an RGB color space file. I need them gray scale solid black in CMYK color mode. I can batch using actions to convert the artwork using "Edit Colors > Convert to Grayscale". However, the document color mode remains RGB. It appears, even after using "Convert to Grayscale", that the RGB color mode goofs up the placed .ai file in InDesign, treating it as RGB and seeing it as a mix of CMYK rather than the 100% black only it needs to be for proper sharp printing.
The actions pallet doesn't record converting the document color mode. Is there a way to automate that file conversion so they are all saved as CMYK rather than RGB, or am I stuck opening each of the 900+ files manually?

While recording the action, from the popup menu in the Actions Panel choose Insert Menu Item, then from the main menu choose File > Document Color Mode > CMYK color.

Illustrator CS2 Start up - Convert color mode dialog box

Using Illustrator CS2, on opening, the usual loading prescreen appears, after which a dialog box appears showing the following text
"Convert Color Mode"
"The document contains objects using both CMYK and RGB color modes. Illustrator allow only one color mode per document. Which color mode would you like to use? (RGB and CMYK appear as option boxes)"
This dialog box appears every time I open Illustrator, even though I'm not actually opening a document.
I've tried adjusting the Color Settings (Edit> Color Settings) but this hasn't affected the dialog box appearing.
I've checked all the usual sources of help but can't identify any cures.
I want to be able to change this so the dialog box no longer appears as it tends to "hide" behind all the other applications I have open at the time and can be difficult to get to, meaning opening Illustrator is a 5 minute battle.
Any ideas?
Thanks

You haven't messed with the startup .ai files have you?
You might try deleting the ai prefs file (see FAQ), though that might be a reach in this case.

Illustrator CC: Changing Document Color Mode + Edit Colors

Let's say I'm going to export a PNG.
If I switch the Document Color Mode from CMYK to RGB, IS IT THEN NECESSARY to also Edit/Edit Colors/Convert to RGB, if I'm just going to select each element and assign specific RGB values anyway?
In other words, is simply switching the Document Color Mode to RGB sufficient before manually assigning specific RGB values?
I'm thinking Edit/Edit Colors/Convert to RGB or CMYK is just relying on Illustrator's best judgment. Am I correct?

Color management needs to be set up in a way that it works as you want it to. Don't turn it off.
BTW: actually you can't turn it off. It is so deeply integrated in modern software that it will always work somehow.
Have all the numbers you set up in your colors be transferred correctly into the PNGs? Then don't worry.
When converting your document from CMYK to RGB all color values get converted: object colors as well as swatches. No need to use the Edit colors function.
When using File > convert to RGB resp CMYK document color mode, Illustrator applies the rules you have set up in Edit > color settings. That is: the profiles, the conversion engine, the intent.
Change one of the settings and you get different colors.
If you need to use specific RGB values, first convert the document color mode, then set up the color swatches and apply them to the objects.

Why is illustrator converting to RGB when I don't want it to?

I am trying to use artboards to save several versions of a logo (8 different versions). I was hoping to have all 8 versions in one document in both RGB and CMYK (so essentially 16 artboards). I'm gathering this is not possible because when I convert one logo to RGB then all of my other logos convert automatically to CMYK (except PMS versions, they remain accurate.)
I moved on and made 3 different documents, one for PMS, one for RGB, one for CMYK.
I started with the CMYK doc in CMYK Color Mode and converted my PMS colors to CMYK. No problem.
I did a Save As, set to RGB Color Mode, and started changing my colors over to RGB based on the conversion from the PMS.
At this point my CMYK Color Mode, separately saved file, converts all of its logos to RGB.
Is this a glitch or am doing something horribly wrong? I'm not at all new to illustrator, though I am relatively new to CS6. I thought artboards were going to be a Godsend for versioning logos but it seems I've wasted far more time trying to do it this way.
Can anybody help?

I did try that first. However, I've long since moved on from that. I'm talking I convert it in a file and it changes in a file that isn't even open. See below...
I moved on and made 3 different documents (files), one for PMS, one for RGB, one for CMYK.
I started with the CMYK doc in CMYK Color Mode and converted my PMS colors to CMYK. No problem.
I did a Save As, set to RGB Color Mode, and started changing my colors over to RGB based on the conversion from the PMS.
At this point my CMYK Color Mode, separately saved file, converts all of its logos to RGB.
Furthermore, to be sure. I took my PMS document and made two new documents using the Save As (both directly from my PMS only document.) I closed all of the documents and converted them individually. I opened RGB first, set it to RGB color mode and converted from PMS to RGB. No problem. Did the same for the CMYK, except when I said "Recolor Artwork" instead of coloring to CMYK it colored to RGB so I used the swatch pallete which worked. Closed the document. Reopened all 3 documents. My RGB document has now converted itself to CMYK. It's like they're all linked together. Change one, change all.
I even made a test document with a CMYK circle in it, saved as into a new document. Closed the test doc, converted the circle to RGB. Reopened the test doc and the circle is RGB. I am totally baffled. I've also tried AI files instead of EPS, same thing.

Eyedropper tool wrong rgb color

I've placed an rgb image and on top of that a vector square which I wanna give the same color as the bright green one in the rgb image. So I used the eyedropper tool on that bright green color. But as you can see it give a more dull greenish color. The document is in rgb mode. I would expect this more when I was working in cmyk but I ain't. Why isn't the eyedropper tool picking the bright green color? The image is in rgb, illustrator is in rgb, in photoshop I can see the bright green color in the rgb image. So why isn't illustrator using this bright green color with it's eyedropper tool?
Edit: Turns out the eyedropper tool only works correctly (while illustrator is in rgb color mode and the image placed is also in rgb), when the image placed is embedded and not just linked. After I dragged the image on the page and go to Links to have the image embedded and then use the eyedropper tool, I get the exact same color. Seems a bit odd that it won't work the same way when the image is linked?

The eyedropper only works accuratelyon vector objects. Shift eyedropper is misleading as the color chanegs but never has been accurate on bitmaps in Illustrator. Shift eyedropper does not pick up the pixel value, but what is being sent to the monitor going through conversions for color mgmt, color modes, etc. Open the image in photoshop and use the eyedropper set to 1 pixel.

Printing RGB colors - Conversion to CMYK?

Hi,
I have been working for a little while in converting my old RGB colors to CMYK printer friendly colors.
However, I carefully choosed my printing friendly CMYK colors to be as close as possible to the RGB colors but the prints are dull !
On the other hand, when I print my file withj RGB colors using the PDF Distiller tagged with Adobe1998 profile and send the file to the printer, colors look smarter !
It means that the CMYK colors I picked myself are not good enough anf the Color Managment in Adobe PDF or Illustrator are better than me ! As follows:
- In Illustrator -> Print -> Color Management tab -> Color Handling: Let Illustrator determine colors
- in Acrobat Reader -> Print -> Color Management tab of the plotter: Application managed colors
Both ouput similar quality prints, and better than my own CMYK colors !
Are the Application Color Management engines in Illustrator and in Adobe Reader similar in their conversion?
How can I find out which are the CMYK colors printed when the application (Reader or Illustrator) manages colors, from my initial RGB colors? I would like to use them directly in my document...
Thanks

Hi,
Thanks for your response. I put these color issues on hold because I had no time to search more on that recently...
However, I have still lots of questions about color conversion!
When I said "carefully choose" CMYK colors, it means CMYK colors printable and which look similar to my old RGB colors on-screen. But of course, screen is not enough!
What I noticed is that when I print my old RGB colors (not in printer color space), Adobe Reader or Illustrator were able to make good conversion to CMYK for printing.
Now, I would like to find out to which CMYK color codes Adobe Reader or Illustrator converted my RGB colors? Then, I would be able to use these CMYK color codes directly in my application...
Is there any way to find out that?
Cheers

Is the CMYK color mode available in Photoshop Elements 12?

In taking a photography course I was introduced to color printing modes in Photoshop CS6 which includes CMYK as one of the modes. I am currently using Photoshop Elements 11 which is limited to the RGB color mode. Does Elements 12 offer CMYK?

No, this is one of the areas where Adobe is determined to keep a difference between PSE and full Photoshop. No version of PSE has CMYK support and it's unlikely to come in a future version, either, I'm afraid.

Convert document color mode to Pantone/Spot

I have a document in which i have 2 layers, each layer contains shapes. one layer is supposed to be Pantone 293, the other layer is Pantone 296. right now, the colors are in RGB. I saved as is, then saved as PDF and the printer whom im sending this to, said the PDF printed out in 4 plates (CMYK) and i need only 2 plates, hence, i need the document to be in a spot color mode. How can i do this? How do i convert the colors i used in the shapes now to spot colors in CS3 version?

First I recommend changing the document to CMYK mode.
Here is the traditional fix: Window: Swatch Libraries: Color Books: Then select a Pantone Solid library. Show the Find field and type in your numbers. Double click the color chip to add it to your Swatch panel.
In the Swatch panel: Add Used Colors. To replace the global colors you are using currently, click on the Pantone swatch first, then the current swatch and select "Merge Swatches."
If you have lots of different shades of colors, you will have to create tints of the two spot colors.
Check your results using Window: Separations Preview to make certain you don't have CMYK being used. If your document is RGB, you will not be able to utilize Separations Preview (that's why I suggested the mode change)
You can also use Edit: Edit Colors: Recolor Artwork to make global color changes. But this is a somewhat complex dialog and takes getting used to. I recommend familiarizing yourself with this tool before using it in live production.

Why does my Bridge read RGB or B&W for the Color Mode on a file, when in Illustrator I have set it to CMYK?

I'm kind of stumped and this has been a question of mine for some time. I did some further digging on it, and did find that what it's reading is the Photoshop Color Mode XMP data, which is odd since the files were never in Photoshop, and were created in Illustrator. Is there a way to remove this info? How do I fix it?

Probably can be chalked up to one of Illustrators mysterious color issues.
Therefor it might be best to drop this question in the AI forum itself. I know to less of AI but just tried a bit with a new document, you can't convert to a new color profile like used to in PS, only select CMYK or RGB and assign a profile but that is not the same as converting.
Also in color settings it says by default to preserve numbers in stead of the profile itself.
And yes, mysteries are common at Adobe, although being one company one doubts often if they are even aware of the existence of Bridge and even other applications in the suites. Not even all file types of Adobe seem to be fully supported in Bridge…
