Roger Oberholzer

Roger Oberholzer Flexo Service GmbH

I am the founder, owner and managing director of Flexo Service GmbH.


Since my 15th year of life I have been working continuously in flexography, longer than half of my life! The first eight years as a flexographic printer on a wide web flexo printing machine, the following 17 years as process engineer for Gallus label printing machines.


Especially the 17 years for Gallus have deeply influenced me: In over 70 countries across all continents, I have gained valuable experience solving various printing problems, training hundreds of label printers, and advising on increasing production efficiency. 


Along with working in flexography, I successfully graduated from Polygraphic Academy HF TGZ Zurich, I am active in the Flexo Suisse association as examinations expert and was a member of FINATs Technical Committee. Since 2016 I am working as teacher for young flexographic printers at School of Design in Zurich ( 


After more than 25 years in flexography, in 2018 I founded the company Flexo Service GmbH and now work independently for the valued customers throughout the world. I like to pass on my accumulated experience to solve problems, to improve the quality and to increase the efficiency. 


I am able to support you in following areas:

Label printing / flexible packaging printing / UV inks / solvent based inks / water based inks / screen printing / coldfoil stamping / hotfoil stamping / die-cutting & matrix / reverse side printing on glue / lamination. I have practical experience on following printing machines: 

Gallus RCS / Gallus Labelmaster / Gallus EM280 / Gallus ECS340 / Gallus EMS as well as central impression machines from Windmoeller&Hoellscher and Fischer&Krecke.
