HI PAM ... THE PROOF PRINTOUTS FROM THE ART DEPARTMENT ARE MADE BY CANON DIGIAL COPY MACHINES .... DEPENDING ON THE COLOR TONERS /INKS ... AND THE SERVICE P.M. CYCLE ON THE COLOR COPIER MAKES THE PRINOUTS DARKER OR LIGHTER DORUNG RUNS .... THE OPERATOR PROBABLY DID NOT NOTICE SLIGHT VARIATION IN COLOR ETC. I USED TO OWN A KINKOS TYPE STORE. HOPE THIS HELPS ... THANKS RICH BURGEL
