Flexographic printing device and a method of simultaneously printing at least two material webs having different thicknesses

A method of simultaneously printing at least two material webs having different thicknesses in a printing device, comprising:

• feeding printing ink from a printing ink chamber onto a printing roller using an anilox roller;
• moving at least two material webs having different thicknesses through a printing nip defined between the printing roller and an impression roller, the printing roller carrying on a surface thereof an image to be printed and the impression roller having a surface, to thereby print the image onto the at least two material webs;
• and
• adapting the printing device by arranging at least one of the following (I)-(III):
• I. a radial extension of the surface of the printing roller carrying the image to be printed such that it is adapted in respect to a thickness of the respective material web to be printed;
• II. the surface of the impression roller such that a radial extension along the surface of the impression roller is adapted to the thickness of the material webs to be printed;
• and
• III. a surface of the anilox roller such that a radial extension along the surface of the anilox roller is adapted to the thickness of the material web to be printed.
