I just finished my first 4 color process print on paper using Speedball process colors. The registration is tight. All colors are printing perfect and consistent. We are used to printing 4 color process on shirts where we can print wet on wet C,M,Y, and then K.
On paper we tried this order, drying between colors, and it all leaned yellow with orange and an army green in the color bars. We also tried Y,C,M, and then K. The color bars look pretty close to being on-point, but the photo seems to be heavy in the reds.
My best guess is that the correct order for these inks would be Y, M, C, and then K. Can someone confirm this, so I can stop running fancy tests for my personal satisfaction, and get back to work on client orders?
