Solventbased, UV-curable and Latex Inks


Crystal clear polyester film with highly transparent ink receiving layer and a super clear removable solvent based adhesive. Suitable for labels, posters, displays or as backlit applied directly on light diffusion boards. SIGUV can used for glass decoration and shop window graphic advertising - showcases and display cases look like "direct print".

Application note:
Glass has a tendency to absorb heat when it is exposed to solar radiation. In insulating glass panes that are specially covered with dark areas in whole or in part, glass breakage may result due to thermal stresses with extreme temperature fluctuations. We therefore recommend to cover only max. 25% of the glass size and to avoid dark areas of colour with high colour saturation if possible.

UV-Inks / curing:
SIGUV 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.
Furthermore 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.

Latex-Inks / Drying:
Before printing it is absolutely necessary to check that the correct drying temperature has been set by carrying out a trial print. Too high drying temperatures can lead to a deformation of the film which can later cause further problems while processing.
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.
Residual moisture which is contained in latex inks after printing must be fully dried before further processing. For this reason it is necessary to take long enough drying times into account. The drying time of the printed media depends very much on the quantity of ink amount. When printing the film in a roll-to-roll process, the printed strip must be unrolled and laid flat as soon as soon as possible until final drying. Residual moisture due to insufficient drying times can lead to blocking during transport in rolled-up form. During lamination such residues can negatively impact the quality of the finished product (flatness, shrinkage behaviour, anchorage, etc...).

In order to avoid denting the film laminate during transport we basically recommend to wind up the finished printings on paperboard cores with minimum diameters of 76mm.

For an optimal transparency on glass we recommend a wet mounting of SIGUV. Before mounting the glass must be clean and free of dirt, grease or other residues. If applied onto curved surfaces please be aware that label lift off can occur especially if the radius is tight. It is up to the user to test for there own suitability/application, due to the wide variety of surfaces, applications & desired results.
During mounting the glass should have a temperature of at least 15°C. As mounting help we recommend water mixed with some washing-up liquid or the use of a transfer liquid such as “Splash” from Marabu printing inks. For the mounting humidify the glass and the SIGUV adhesive uniformly and apply the printed
film with the adhesive side on the glass. Then remove carefully the water with a squeegee from the middle to the edges and absorb it with a clean cotton cloth or some soft paper. The water must be completely removed to avoid the formation of bubbles due to a rest of humidity.

Removal from Background:
The removal of the mounted film from the background is facilitated by heating it up with a hair dryer or hot-air gun. For this the film must be detached slowly and steady in an acute angle. Residue-free removable up to 6 months indoor and outdoor use adhered vertically to glass surfaces in accordance with DIN EN ISO 4892-3.


  • 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.
