Export PNG in CMYK vs. RGB. Changing colors.

Short version: Using Illustrator CC. I correctly exported a PNG logo in RGB (sent to client), but the new PNG logo looks much different than the old PNG logo that was exported incorrectly in CMYK (sent to client long ago).
Client wants to know why the NEW PNG logo looks so different than the EPS logo and the OLD PNG logo (all starting with the same Pantone color).
Longer version:
I recently sent logos to my client in different formats.
ai, eps, eps CMYK, pdf, and png
Prior to creating the PNG version in Illustrator CC,
I changed Illustrator's color mode to RGB, then converted my Pantone colors to RGB (specific values per the Pantone book), then exported as PNG.
This created a much different blue than the CMYK eps version.
Someone else on the client side is working with my files and questioning why the blues look so different. The Pantone eps vs. the RGB version.
Problem:
In the past, the PNGs had been created incorrectly--They had been exported in CMYK mode without converting anything to RGB and they matched much closer to the EPS version.
Now they are asking why there is such a big difference.
I did the process correctly, I'm not sure how to answer this. Why do they look so different?

So if I just leave the Document Color Mode as CMYK, leaving with the logo set in it's specific Pantone colors, and then Export/PNG, that will covert my CMYK colors to RGB for me. Seems almost too easy. Just go File/Export/PNG, but okay.
And while that may give me a better perceptual match, here's the other side of the issue.
They've given me and their web company specific RGB values for their logo. These are based on the Pantone book, and likely different than the conversion Illustrator will do.
The idea being, they want the website and logo to be the exact same blue. And they are based on the values they gave, but they look different than the original Pantone. Brighter and more vibrant. I'm dealing with another member of the client team, trying to use Illustrator on her end for smaller tasks, and she wants to know why the rgb PNG logo (which I entered in manual values for based on the Pantone book), is so different than the Pantone eps file. In the past, when I just exported as a straight PNG without tinkering, the perceptual match was there. Now it isn't. How can I explain this?

Printer Requested Exporting Document in CMYK, with one other color so he could color correct to his printers. How do I do this?

I have a client that was originally going with a metallic Pantone color and last minute decided to change their mind to cut costs. So after talking to the printer (because the conversion color is way off) he requested that I export the document in 5 color processing. He wants CMYK + the color that would originally have been the metallic pantone so he can go in and grab that one color and color correct as needed on his printer. Can someone please let me know how I export CMYK + one color which will also be in CMYK.
Thanks!

Incase anyone comes across this same issue, you can create a new swatch as a "Spot Color" even though it is CMYK and it will export as CMYK + 1 other color. Hope this helps anyone else who comes across it.

RGB Logo uses Overlay transparency... need in CMYK for print but color changes in overlay

I am working with a logo someone else created in RGB using the Overlay transparency. When I convert it to CMYK just one area seems to "change color".
I tried inserting both versions here - but it isn't working too well. Basically, in the image below the outline of the "scales" appears darker in the CMYK version for printing. Any ideas on how I can adjust it to print in the same vibrant color the RGB is showing?

fill in info RGB is light (like on your screen) and adds more light when mixed, CMYK are pigments and adds more color or multiplies, when mixed

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);

Getting darkened/ washed out colors when exporting png from illustrator

Hey everyone I'm trying to figure out a remedy for this, I am getting darkened less saturated colors when exporting a logo png from illustrator, jpeg's looke fine, even when copying this logo into indesign and exporting the colors look fine there as well. I think it has something to do with the icc profile being embeded in jpegs but not pngs, but I'm not sure. My illustrator document is set to display blacks accurately, document color mode is set to RGB, assign profile is set to working RGB: sRGB, and under color settings working space is sRGB and cymk is U.S. Web Coated SWOP v2, color management policys off for RGB and conversion options Adobe ACE (all under the color settings options). I've also tried to create a new file for web and copy and pasted my logo and tried to export that way and it didn't do anything. Any jpeg will look fine, the png even in save for web will look fine until I export or preview. My only current remedy for png at this point is to export it as is, then open it in Mac's Preview and turn up the saturation. Any help would be appreciated, I'm also using Illustrator CC and am on mac 10.7.5, thanks.

Any other solutions? I notice if I open the AI file in photoshop and export the png from there with "embed icc profile" checked then I get the same colors that I see while in illustrator, and when I export jpegs from illustrator, but exporting pngs from illustrator always changes the color/ makes the colors look duller.

Export to PDF changes colors

I have a longstanding problem that I hoped would have been fixed but has not. I had this in prior versions of Keynote and in prior OS's. I am now using Leopard and Keynote in iWork 08. All software is latest version.
I use a bright green font and various other bright colors in keynote. When I export to PDF many (not all) of the colors are noticeably muted and washed out. It is particularly noticeable in the bright green (called "spring" in the crayon pallete in keynote). Other colors change tint substantially.
The overall effect is to go from a vibrant presentation to something that looks very dull. I am referring here to colors as they appear on the screen (printing is a whole other issue). If I put the PDF version next to the keynote version on my large Apple LCD display, they look completely different.
This is not just a subtle effect. It is very noticeable color change.
Today I gave a presentation using Acrobat Connect and noticed the screen capture seemed to also have a color problem, and the presentation appeared on the remote screen with the same color changes as if it had been turned into PDF.
Presumably there is something very different about the way Apple and Adobe handle colors. Is there some setting I need to adjust or is this a bug? It seems like a pretty big issue to me.
Any help greatly appreciated.

As pdfs are normaly calibrated for printig, they mostly use CMYK. CMYK cannot show all colors you monitor can do, especially deep greens or blues. But they look the same when printed, so if you change the calibration of the pdf to some RGB profile, it may look like in keynote, but not anymore the same when printed.
Good theory, but I think it is wrong. When Mac OS X produced PDF files, it keeps the colour space of the original pictures. CMYK stays CMYK and RGB stays RGB. (You can see this using preflight in Adobe Acrobat, if you have that application.) The important thing is that the file, regardless of colour space, should have a good colour profile, and Mac OS X does it best to do that too.
But apart from that, I have no idea what could be wrong in the case described above.

Change swatches from CMYK to RGB

Okay so I've just realised that my documents are CMYK and have changed the settings to RGB (File > Document color mode > RGB and from the colour fly out menu) although I notice that when I hover my mouse over the colors in the swatches panel that it shows me the CMYK values.
Could someone please assist me with this as I'm not sure why this is happening.
Thanks in advance

to change color definitions--from the 'color' menu select the flyout menu in the upper right corner (indicated in attached pics) and change from cmyk to rgb

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

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.

AI CS3 Color Palette CMYK: I manually change C, and MYK values automatically change. WHY?

As I was searching the Adobe forums and Google for a resolution to this problem, the problem STOPPED. I am absolutely baffled, because I didn't change anything! Still curious to know what was going on:
I'm creating color swatches to print on a high-quality printer (digital process) so I have about 200 color blocks on a page.
I have been manually entering CMYK builds in different ranges, for example:
32/0/68/0
32/0/70/0
32/0/74/0
So that I can print them out and match the color, like a Pantone swatchbook, only in CMYK full-color/process printing.
After doing this for a few days, all of a sudden I went to change a square of color to a different color. I changed the CYAN value to something else (by typing a number in via my keyboard, rather than the slider), and when I tabbed to the MAGENTA field, all the other values automatically changed to drastically different numbers.
I tried manually changing the MAGENTA, and it would alter the CY&K. I tried manually changing the YELLOW, and it would alter the CM&K. In fact, it would not allow me to type in the exact build I wanted to. Strangely though, I was able to drag the sliders and that didn't alter the other values.
I have no idea why this happened, or how it resolved itself. I had even quit out of Illustrator and re-opened the document and the problem persisted.
Does anyone know about a setting - maybe I indavertently pressed a keyboard command without realizing it?
I'm working in:
Adobe Illustrator CS3, .AI file in CMYK color settings with Proof Colors turned ON (and "Simulate Paper Color" turned ON)
Color Settings: U.S. Web Coated SWOP v.2 (and "Preserve CMYK Numbers" box checked)
MacBook Pro Core i7
Mac OSX 10.6.3 (Snow Leopard, I think)

If you do a variety as you describe it does require some work and diligence.
You should set up two different color settings and if you use the bridge change them globally throughout the suite through the bridge.
Edit>Creative Suites Color Settings
One setting for Web and Print (Press) and the other for Photograhy and Print (Press)
The CMYK should be the same in both either Adobe RGB 1998 or Adobe Pro Photo RGB or Color Match RGB.
Then select the one for the type of project you are working for for print it could be either on since you would work in cmyk.
For web the web setting of course which should be sRGB. You have to make different copies of the files for web then for print as the color has to be adjusted for each.
And use the right one for each as well. You should check the profile each image as well and make them match for each type of document, it is not just good enough to have your settings correct does little good if an embedded profile is a mismatch, you want to do the adjustment your self and do any adjustments required.
In other words color management is work.

How to change color profile of exported photos in iPhoto

Hi
Please help. I want to change color profile of exported photos in iPhoto. The iPhoto in my macbook air with mac OS X Yosemite always exports photos in Adobe RGB 1998. How can I make it export photos in sRGB color profile?
Thanks

You can assign a color profile with Preview.

Photos cmyk or rgb color

Do photos prepared with photoshop (windows) to be assembled with indesign cs5.5 and to be printed in a magazine: must they all be placed all cmyk color?

Save them as PSD or PDF in Photoshop, Import images in RGB with color profile.
If the printer needs CMYK you should convert them on export to PDF, better is to do it later.
Results of converting in Photoshop or InDesign are exactly the very same. But importing RGB in InDesign gives you much more flexibility. In Photoshop you can turn on the CMYK preview, even if you work in RGB, you can even see the different plates.

Years ago, Pantone made a product called ColorWeb Pro that
had software and also a fan of ink samples and Pantone's
recommendations for CMYK and RGB (Web) values that would be the
best representation for each ink. For the Web, they'd researched
the ink colors and tried to account for variations in graphics
card, monitor, and printer hardware. Because of that variation,
there's really no hard and fast conversion you can use. (Plus, the
RGB colors that are best for the Web won't be the same as the CMYK
colors that are best for print.)
Pantone has a number of current products for color matching.
You might be better off contacting them and getting advice on what
product would work best for you.
Pantone Web site
For a metallic color, you might want to use a subtle gradient
to simulate a reflective effect, though.
Good luck!

CMYK to RGB color conversion?

Hi,
I have to convert CMYK color array in the RGB color space and vice versa.
I am using the following code;-
UID colorUID = iDrawing->GetColorUID(kFalse);
UIDRef colourUIDRef(iDrawing->GetDataBase(), colorUID);
InterfacePtr<IColorData> colorData(colourUIDRef, UseDefaultIID());
char
strColor[16]={0};

    ColorArray rgbColor = Utils<IUIColorUtils>()->GetRGBColorValue(m_DB, colorUID);
    sprintf(strColor,
"#%.2x%.2x%.2x", ToInt32(rgbColor[0] * 255), ToInt32(rgbColor[1] * 255), ToInt32(rgbColor[2] * 255));
else
    ErrorCode errStatus = GetRGBColorStr(colourUIDRef, strColor);
ErrorCode GetRGBColorStr(UIDRef colourUIDRef,
char* strColor){
    ErrorCode status = kFailure;
    do
          I
nterfacePtr<IColorData> colorData(colourUIDRef, UseDefaultIID());          IDataBase* m_DB = colourUIDRef.GetDataBase();
// If color sapce is other then RGB then get the colour array
    ColorArray colourArray = colorData->GetColorData();
    // If the colour space is CMYK then convert it to RGB
    if(colorData->GetColorSpace() == ICMSProfile::kSourceTypeBuiltInCMYK)    {
          IDocument* document = Utils<ILayoutUIUtils>()->GetFrontDocument();
          ColorArray rgbColor = Utils<IColorSystemUtils>()->ColorTransform( document, colourArray, ICMSProfile::kSourceTypeBuiltInCMYK,ICMSProfile::kSourceTypeBuiltInRGB);
     sprintf(strColor,

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.

JPEG changing color during export to Word

When I export my file into Word, one of my jpegs changes color dramatically. From a gold hue to bright purple. Does anyone know why this might happen (no other colors in the file are changing) and how to prevent it?J

Are you sure that it is a .jpeg? This happens when the colorspace of the file is not defined or is alterred by the receiving System/Software. Usually .jpegs are OK but other formats may have different colorspaces that the PC System is not reading or reading incorrectly.
If it is not a .jpeg it maybe in a format with indexed colors, indexed in a low bit setting that is again being misread by Windows.
You could try opening and resaving the particular file in Apple's Preview.app to jpeg which should apply some colorspace at least a default one and may correct the problem.
