Compatibility

  • Useable on most large format Ink Jet printers using latex inks.
  • Useable on most large format Ink Jet printers using UV curing ink systems.

Handling

  • SI 438 should be printed with stretchable UV-curable inks. We don’t recommend standard UV-curable inks since the colour layer could possibly crack after printing or during further processing.
  • It is necessary to set the UV-curing correctly in order to avoid a deformation of the film due to the heat generated by the UV-lamp.
  • UV inks absorb water in a wet state due to the system. The print surface swells and is mechanically unstable during this time. After the ink layer has dried, however, the surface is hard and scratch-resistant again. UV inks also require a certain post-curing time after printing. The printed film surface may therefore only be loaded after 24 hours at the earliest. Due to the risk of blocking, this must be observed especially when printing from roll to roll.
  • High air humidity during the printing process may lead to banding in the printing direction and to striations in the printed image caused by the transport or by the press rolls.

  • Note for Latex-Inks: To avoid the effect of rewetting (oil film on the print surface due to defective anchorage of ink) it is necessary to establish the optimal drying parameter. This can be done by means of print tests before production print. Rewetting can appear several days after printing when the drying condtions are defective. The rewetting can also be dependent on the given ambient conditions and the composition and consistence of the printing theme. When creating a media profile, this circumstance must be expressly taken into consideration.

Storage

  • Shelf life: 1 year after delivery
  • After printing the remaining roll must be removed from the plotter and stored in its closed original packing in a cool and dry environment.
