This is really odd. Customer sends me .ai file of a yellow heart. The file is just a transparent bitmap within the file. So I unmask, add cut line and save the file. Later when my employee printed the file the yellow turned to light cyan. Luckily I seen and noticed the color issue. I found this odd but what is even more odd is when you preview it before opening the file the heart shows it will be yellow. Then you open and you get the cyan. My only workaround I found was to import the original file and print. This is fine but if we ever reprint we will have to go through this odd process again (I added a note about it). Anyone ever seen this?
