I have a brochure which I'm trying to print it has a few shades of purple and grey.

At one printing center, Digital Printing, the colors came out completely wrong as blues instead of purples and very dark gray. I tried a different center and the purple came out kinda pinkish but the gray comes out as yellow.

Originally the file was CMYK but I changed it to RGB later and saved it as PDF which was later used for printing.

Edit: I don't really know the type of the printer but maybe I'll try saving it as CMYK and print it again and see how it turns out

  • Are the printers RGB or CMYK??? Sending RGB data to a CMYk printer may be an issue. And color calibration at the "print center" (which you can't control) is also an issue. – Scott Sep 17 '18 at 17:30

Call the printer company and ask what Color Profile (ICC colour profile) they use in their printers. If they answer "we don't use any color profile", change to another printing center because this is a copy store, not a printing company.

If they are really professionals, you can get two answers:

  • A Standard color profile: in this case go to Menu Edit > Assign Profile and choose the standard profile used in your country.
  • A Custom color profile: ask your printer to send you this profile and save it into your OS's Profiles Folder. For Mac users:

    HD > Users > Your User > Library > ColorSync > Profiles

    Maybe be you should restart Illustrator to see it in the list and then assign this profile to your document.

Readjust the colors of your document according to the new profile if necessary. Save it and send it to print.

Remember if your monitor is not properly calibrated, the colors that you see on your screen may differ and quite a lot of those that will appear in printing. The first step before everything is to well calibrate your monitor according to the type of work you usually do.

    This last paragraph about calibration is very important. But the screen is less important than the printed final. If the OP is really having trouble matching colors between systems, then a good last-ditch effort is to make a document of only color swatches, have a proof made by the print-provider, pick the color swatches that match closest to the ideal, and then set those colors in a document used specifically for the printing. Basically a homebrew swatchbook – Yorik Sep 18 '18 at 14:29
