I am having issues with printed colors not matching what I see on screen. I am using corel x4, epson WF1100 and JPSS transfer paper. So far things have been going fairly well, colors haven't been an exact match, but close although a little dull, also some yellow left on paper after peeling. Today I tried to print a pink and brown vector pattern and the pink is purple and the brown is black. I read a few posts on adjusting the contrast and CMYK values but don't know 'where' to change these values at. If someone could point me in the right direction or offer any other tips I would greatly appreciate it.
