- To avoid set-off, use UV printing.
- To avoid miss registration, use a low-heat lamp
(water-cooled or infrared-reduction type).
- When selecting a UV offset ink, consult with
the ink manufacturer and perform a test-print
before making your final selection.
- When using offset printing, use as little water
in press dampening as possible.
- To avoid miss registration, set the tension
at the lowest possible level (less than 20 kg/m).
If the tension is too high, the sprocket-hole
pitch will not match, causing problems at the
collector.
- When printing on a carbon form, pay careful
attention to the drying temperature to avoid stretching
or shrinking of the YUPO®.
- For perforated sheets, pay particular attention
to the spacing of the blades.
| Vertical perforations |

- When the tearing area of a perforated sheet
is close the edge, the paper may tear easily.
- The spiral method is ideal for folding delivered
paper. When using thin YUPO®, adjust
the timing beforehand.
