ABSTRACT:
The present invention is directed to preventing image damage caused by pressure applied to print media during a folding process, by using pressure and abrasion resistant inks only on those sections of print media that are subjected to pressures that would otherwise damage the images printed on those sections. Images on other sections of the print media are printed using less expensive or general purpose inks.
