• Remove the self-adhesive supporting foam from the protective paper and affix the
3 mm wide supporting foam circumferentially
(at the trim-off area) to the base blanket (Fig. 4). Should there not be left any space
free of colour it is possible to glue on perforation lines instead of supporting foam.
The supporting foam ist used to keep the print sheet true to register in the free
areas on the impression cylinder.
TIP:
With some paper grades resp. by longitudinal and diagonal unwinding there are vari-
ous pressure conditions in the printing machine. Patching the traverse processing rules
(parallel to the cylinder axle) is recommended in order to compensate for the differ-
ences in pressure. Here we recommend using CITO TAPE in the thicknesses 0.03 mm/
blue or 0.05 mm/red.
Simply stick a patching tape onto the back side of the grid sheet at the appropriate
positions (Fig. 5).
