● Go to the front panel and press , then Substrate handling options > Extra bottom margin and Extra top margin. Set both margins to 100 mm. If that is not enough, try higher values. ● Increase the vacuum level in steps of 10 mmH2O. Do not exceed the following limits: 20 mmH2O for banners, 45 mmH2O for vinyl, and 60 mmH2O for other substrate families. Consider reducing the vacuum percentage at the front of the print zone for thin substrates. ● Increase the number of passes. ● Make sure that the substrate is stored in the same room in which the printer is located. ● Try using the substrate edge holders. The substrate is deformed or wrinkled If your substrate is deformed or wrinkled by the curing process, change the temperature settings before printing the next job, and advance the substrate, using the Move substrate option in the front panel's Substrate menu, so that the next job will be printed on undamaged substrate. If the problem appears only at the beginning of the print, try the following suggestions. ● Go to the front panel and press , then Substrate handling options > Extra bottom margin and Extra top margin.

The substrate has shrunk or expanded During the printing process, some substrates may shrink, while others may expand. If this happens, the dimensions of the print will not be correct. As a general rule, you can expect the following percentages of shrinkage: ● Banner: less than 2% ● Self-adhesive vinyl: less than 0.5% ● Backlit: less than 0.5% ● Paper: less than 0.5% ● PP & PE synthetics: less than 1% The framing problem may be solved by printing a sample and adjusting the size of the image in the RIP. You may reuse this value for all your future prints with the same substrate, although special care must be taken when using banners, as the shrinkage may vary up to 1% depending on the amount of ink used in the print. You can expect the following variations from one print to another: ● Banner: less than 0.3% ● Self-adhesive vinyl: less than 0.1% ● Backlit: less than 0.05% ENWW The substrate is deformed or wrinkled 67

The substrate has shrunk or expanded
During the printing process, some substrates may shrink, while others may expand. If this happens, the
dimensions of the print will not be correct.
As a general rule, you can expect the following percentages of shrinkage:
●
Banner: less than 2%
●
Self-adhesive vinyl: less than 0.5%
●
Backlit: less than 0.5%
●
Paper: less than 0.5%
●
PP & PE synthetics: less than 1%
The framing problem may be solved by printing a sample and adjusting the size of the image in the RIP. You
may reuse this value for all your future prints with the same substrate, although special care must be taken
when using banners, as the shrinkage may vary up to 1% depending on the amount of ink used in the print.
You can expect the following variations from one print to another:
