Hi. having some trouble with cmyk photos printed on a polybag mailer. Photos came out very dark, anything dark or black has become an extreme dark mass, lacking all mid tones and details. Also having color shifts in medium tone shadows on an aqua object, almost like a gain in yellow only, shadows dirty. Using an international printer that has provided no clear specs for the imaging.
Who has printed photos on plastic polybag mailers? Have you found good image settings? Printer wants an .eps file so our logo is sharp over these photos. Thanks
