Diecutting/creasing/perforation result
Problem
Impression of the rule base on the print-
ing substrate
Impression of the creasing channel on the
printing substrate
Poor tearing of the perforation rules
Diecutting is mirror-inverted
Unwinding of the diecutting form does not
fit
Crease cuts off
No diecutting/creasing/perforating on the
beginning of the sheet
Incorrect cross rule diecutting/creasing/per-
forating
Processing rules move around
Diecutting result uneven and base plate agi-
tates
Diecutting result uneven and grid sheet agi-
tates
Diecutting result uneven and RSP direct fit
flexible die agitates
Diecutting form wears out quickly
Possible cause
Maximum printing substrate thickness
exceeded
Maximum printing substrate thickness
exceeded
Transfer sheet padding not removed
Movement direction not considered in the
selection of the rule
Grid sheet not mounted laterally reversed
Reduction of the grid sheet not considered
Creasing rule R1 used in spite of same
diecutting/perforation
Processing start within approx. 13 mm from
the front edge of the sheet
Different pressure conditions
Circumferential supporting foam forgotten
Base plate not tightened with sufficient
torque
Grid sheet not tightened with sufficient
torque
RSP direct fit flexible die not tightened with
sufficient torque
Incorrect printing impression
Solution
Correct the printing substrate
Correct the printing substrate
Remove padding
Please observe the recommendations when
selecting RSP perforation rules
Mount grid sheet laterally reversed
Do not compensate dimensions of the
print sheet by packing the grid sheet!
Use creasing rule R2
Processing start not possible until approx.
13 mm from the front edge of the sheet
Adjust crosswise processing rules
Use supporting foam
Correct the tension on the base plate
Correct the tension on the grid sheet
Correct the tension on the RSP direct fit
flexible die
Correct the printing impression, if neces-
sary make-ready
