Effect of pressure of photopolymer plate to the ground on the compression resistance of transport containers made from tri-layer corrugated board during inline flexographic printing

In the following article, an attempt was made to empirically determine an impact of technological errors on compression resistance of corrugated fiberboard transport containers during inline flexographic printing on industrial slotted – printing – gluing and folding machine. Investigation proves that the printing process has an influence on packaging resistance. It has been shown how important press photopolymer printing plates are to corrugated board adjustment by a machine operator and a correct production technology preparation. Adjusted high pressure due to male/female creasing occurred, caused resistance loss by 13%.
