I'm facing a perplexing problem while exporting a vector graphic (a logo) from illustrator. The document colour profile is CMYK and I'm attempting to export high resolution JPG/TIFF files for print in CMYK. While doing so, I'm noticing the colour values shift a bit. The colour I want my logo to have is the following: Actual colour values

But the output in JPG provides different values when the colour is picked in Photoshop:

JPG Output colour values

I have no idea why this shift is happening. I've also tried to change the profile to "Don't colour manage this document" from the default "Working CMYK: U.S. Web coated (SWOP) v2" in illustrator. But that doesn't seem to have helped either. What am I doing wrong?!

Thanks in advance!

    Why do you need to export a raster format if the destination is print?

  • Also realize the eyedropper in Photoshop can average pixels in a 3x3 or 5x5 area if it's set to do so -- which I believe is the default.

  • Hi @Scott , So the client intends to use the logo in business stationary like presentations, which he prints as handouts for clients. The colour discrepancy is most visible here as it appears a lot brighter.

  • That doesn't really answer the why question. :) Is your client going to have things commercially printed or merely use the office printer? if using the office printer, is it a color laser printer with a postscript level 3 RIP or merely an inkjet printer? Is he going to print from Microsoft software? Microsoft software has no clue what CMYK is. If using an inkjet printer you should give him an RGB file. Inkjets expect to see RGB. They don't understand CMYK unless there's a postscript level 3 RIP, which most inkjets do not have. in other words,. your client may be better served by RGB.

  • And if using MS software.. an RGB PNG file may be optimum. Unless the logo is a perfect rectangle, the transparency possible with the PNG format will be exceptionally useful to the client. If the client is going to print things with a commercial printer, they should use the vector file, not an exported raster image. Basically, I can think of no use cases where a CMYK JPG or TIFF of a logo are actually worthwhile if a vector file exists.
