Diecutting/creasing/perforation result
Problem
Possible cause
Solution
Impression of the rule base on the print-
ing substrate
Maximum printing substrate thickness
exceeded
Correct the printing substrate
(see page 55)
Impression of the creasing channel on the
printing substrate
Maximum printing substrate thickness
exceeded
Correct the printing substrate
(see page 55)
Transfer sheet padding not removed
Poor tearing of the perforation rules
Movement direction not considered in the

Please observe the recommendations
when selecting RSP perforation rules
(see page 53)
Diecutting is mirror-inverted
Base blanket not mounted laterally
reversed
Mount base blanket laterally reversed
(see page 36)
Unwinding of the diecutting form does
not fit
Reduction of the base blanket not con-
sidered
Do not compensate dimensions of the
print sheet by packing the base blanket
(see page 36)
Crease cuts off
Creasing rule R1 used in spite of same
diecutting/perforation
Use creasing rule R2 (see page 36)
No diecutting/creasing/perforating on the
beginning of the sheet
Processing start within approx. 13 mm
from the front edge of the sheet
Processing start not possible until approx.
13 mm from the front edge of the sheet
(see page 36)
Incorrect cross rule diecutting/creasing/
perforating
Different pressure conditions
Adjust crosswise processing rules
(see page 37)
Processing rules move around
Circumferential supporting foam forgot-
ten
Use supporting foam (see page 37)
Diecutting result uneven and base blan-
ket agitates
Base blanket not tightened with sufficient
torque
Correct the tension on the base blanket
(see page 41)
Diecutting form wears out quickly
Incorrect printing impression
