NOTE
Timing of mechanical movements and actions during operation of the printing
press is critical. Operations that occur before or after they are designed to
occur will degrade performance of the press. Timing settings should be
checked and adjusted after repair or replacement of assemblies as noted in
this paragraph.
(1) Test setup. All measurements are related to same position contained in the 360 degrees that
equal one rotation of a press cylinder. The point of reference is the so called “zero position” (“0” posi-
tion) of the press; the point begin line located vertically above the center of the impression cylinder.
This position is marked by an engraved line and the letter “D” between the measuring ring and the
printing surface of the impression cylinder, D/S. Setup the printing press for measurements as
follows:
(a) Put press in impression ON.
(b) Open plate cylinder access door (D/S) (figure 2-279) and insert mounting bolt into
plate cylinder journal.
