Cold Foil Application
SPS® TechnoScreen introduces Cold Foil in combination with Screen Printing.
Cold Foil as a technology has proven itself in combination with both offset and flexographic printing. SPS® now introduces this technology in combination with our range of SPS® STOP Cylinder Presses.
The Cold Foil Application works simple and precise. A special varnish or glue is printed using traditional screen printing technology. After printing a pre-cure by LED UV improves the adhesion of the varnish. The Cold Foil is applied by means of 2 rubberized rollers on top of a large size diameter cylinder drum. The foil remains on the printed area and the rest is stripped away. A final LED UV curing finishes the product.
The SPS® Cold Foil Unit is placed in line with an automatic SPS® STOP Cylinder Screen Printing Machine. The Cold Foil Unit starts with a fold-down transport belt segment in order to keep full unrestriced access to the screen printing machine. Sheets are transported out of the screen printing machine direct into the Cold Foil Unit. The unit activates / deactivates automatic synchronized with the printing machine. As many as 5 different rolls of foil can be loaded in the machine at the same time. The minimum roll width is about 20 cm. The unit is equipped with LED UV for pre- and post-curing. The LED is water cooled. The special effect of embossing can be achieved by printing a high build varnish on which the foil is applied. Fine details can be achieved as well as large surfaces. All depends on the printed image. The unit works within a speed range of 800 to 3.000 iph!
