Herma Self-adhesive Materials has conducted extensive tests with a Trojan2 digital printing machine. According to the company, this inkjet printer with water based-ink produced excellent results not only with HERMAinkjet materials but also with standard self-adhesive materials from Herma. This potentially opens up new possibilities for label printers, especially for the production of small print runs.

The Trojan2 is an inkjet printer with Memjet printheads, and it produces labels with excellent printing quality even with standard self-adhesive materials from Herma that do not feature a special surface coating. According to Herma, these results have been confirmed by extensive tests performed at Dortschy, the Trojan sales partner for Germany and Austria. Previously, inkjet printers with water-based ink required a special primer for better ink absorption. “Our products HERMAwhite (601) and HERMAlaser sheet (135) can immediately absorb the ink. The print image is excellent and the ink dries immediately,” explains Wolfgang Klein, who works in Herma’s technical service team.

“This opens up great potentials for experienced label printers, as well as newcomers in this field,” adds Frank Ackermann, in charge of technical sales at Dortschy. “Combined with these materials, the Trojan2 is an ideal solution, especially for economically printing small and very small runs. Customers who wish to see these advantages for themselves are welcome to visit our demo center in Bielefeld and see the Trojan2 machine in operation.”

Additionally, Herma tested three materials that are specifically designed for inkjet printers on the Trojan2: the papers HERMAinkprint gloss (211) and HERMAinkprint matt (137), and the film HERMA PE inkjet (811). They proved to be suitable for this digital printer, especially with fine lines and screen vignettes. It also deliver great results on other standard inkjet printers with both sheet-fed and web printing. This range is also extremely suitable for Memjet technology which, with its static, page-wide printhead, combines the advantages of an inkjet printer with those of a page printer. Even at speeds of over 300 millimetres per second, images, codes, and identification symbols can be printed clearly and distortion-free combined with the right Herma self-adhesive material.
