CHAPTER 8: PRINT DRUM SECTION
Securing screw on the Squeegee-gap adjustment plate
Symptoms:
(1) If the squeegee gap is too wide, too much ink is transferred onto the inner surface of the print drum and
may result in ink leakage from the print drum. Other problems, such as the master slipping out from the
clamp plate and horizontal line images may start to rip on the master.
(2) If the squeegee gap is too narrow, not enough ink is transferred onto the inner surface of the print drum
and may cause the images on the prints to be too light or images missing from the prints due to lack of ink
on the drum surface, and more than necessary quantity of prints may have to be printed before the image
transfers completely on the paper.
