Application and use
The surface of HERMAtherm top A offers an excellent quality of imprint with all conventional printing methods. Basically, suitability tests of inks should be performed prior to printing. Web temperature during curing should not exceed 50 °C in order to prevent premature imaging or discolouration. Printing speeds of up to 200 mm/s are possible in thermal direct printing.
HERMAtherm top A is phenol-free. This paper is an ideal choice for dry end use environments, such as logistics. As intensive contact with plasticizers might affect the thermal image, for applications on soft PVC films individual tests are recommended.
The pulp for this paper comes from FSC® certified forest management and other controlled sources.
