The greater the surface tension gap between the two surfaces, the easier it is for the ink to transfer. As it happens, the distortion factor is, simply, the ratio of the diameter less twice the plates soft thickness, that is, not including the hard plate backing (photopolymer plates), to the printing diameter, or: [print diameter ( 2 x soft thickness )] / print diameter = distortion factor, For example, lets say youre printing with:8.000 repeat cylinders and 0.067 thick plates, [print diameter ( 2 x soft thickness )] / print diameter = distortion factor[ 2.5465 ( 0.124 ) ] / 2.5465 =distortion factor 2.4225 / 2.5465 =0.9513 = 95.13%. Plate surface tension. Photopolymer plates production by Flexo24 v.2 software. Although it may seem that the tape is simply there to stick the plate to the printing cylinder, the increased demands from the flexo printing process, such as higher running speeds, faster changeovers and cost reduction, mean that the importance of this component cannot be overlooked.
