My art work is in the CMYK color mode and everything is plopped into a single layer so I can print as color separations in a gray scale. This is all good except for one issue. Screen printing requires registration marks to align (register) the different screens (colors CMYK). Every color channel will be printed in black ink for the film positive. The intensity of the black on the film will depend on the percentage of the C, M, Y, or K in the makeup of any particular color. The registration marks are always black so there is no issue with the black channel. I need them very black (not half tone) coming out of every channel.
The registration marks were created with the custom shape tool. I will probably have to change the registration marks color before printing each channel. Change it to very cyan – print the cyan channel. Change it to magenta before printing the magenta channel, etc. This way the reg marks will be very black on the film positive. Maybe there is an easier way; I don’t know
I simply cannot get the custom shape to change color without affecting other parts of the artwork. Thank you for any assistance.
