Testimonial
"We have been in the photo-engraving business over three years. Used wet-plates for two years, and your process-plates for the last year on half-tone work. Each lot seemed uniform with the others and worked well. Have not had a wet-plate bath in the place, even for line work (or half-tone either), for over a year, and have turned out just as good half-tone work as can be done, so our customers say. It is as good as we could ever get with wet plates."—H.... Eng. Co., per G.C.A.
