Having major problems with this. I'm printing on white matte vinyl. Test print has no dropouts.
Blacks are good, but any shade of black that is lighter starts getting purple.
I've tried different profiles: MVCP, GEN1, GEN2, GEN3, and Heat Transfer (which gave me best result).
I've also tried pulling out all magenta from color adjustment. Here is test print. The 1st link is the original photo, and the second link is a print in GEN3 profile with all magenta pulled out. Help me!!!
