• 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 grid sheet
or the direct fit flexible die (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 are-
as on the impression cylinder. Additional supporting foam to reduce the tensile load-
ing on the grid sheet and the direct fit flexible die.
Tip:
With some paper grades resp. by longitudinal and diagonal unwinding there are various
pressure conditions in the printing machine. Patching the traverse processing rules (parallel
to the cylinder axle) is recommended in order to compensate for the differences in pres-
sure. Here we recommend using CITO TAPE in the thicknesses 0.03 mm/blue or 0.05 mm/
red (Fig. 5).
Simply stick a patching tape or the underside of the direct fit flexible die onto the back side
of the grid sheet at the appropriate positions.
In a similar way, RSP flexible dies or RSP direct fit flexible dies can be adjusted for height
during production or, as with processing lines, makeready can be carried out on the reverse.
