To avoid miss registration, use a low-heat UV lamp (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
Uncut: 0.5 mm or less
Cut: 2 to 4 mm
Horizontal perforations
Uncut: 0.8 to 1.0 mm
Cut: 2 to 3mm
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.
