Technical prerequisites

Printing plates for flexo printing

EPDM rubber and photopolymer plates are used. In the case of photopolymer plates, the print quality isinfluenced by the fineness of the screen and the production speed. The printing plates are set by means ofcopying a film or by means of a digital imaging device and then developed. The number of dots lines perpro cm/inch also affects the printing quality. The number of lines on the anilox rollers should be 4 to 5 timeshigher than the resolution of the photopolymer plate.

Recommended Application Rates

Process Inks		Process Inks	Areas
Lines/cm	300 – 500	160 – 180	120 - 180
Lines/inch	760–1270	400 – 460	300 - 460
Pick-up volume (cm3/m2)	2 – 4	5-6	5 -10
Angle	60	60	60
Application rate g/m2	0,6 - 1,2	1,6 – 1,8	1,6 - 3,0
