Considerable work has been done over the past years by Weavexx Corp. t
o investigate the influence of for ming fabric structures on the quali
ty of the final print. The conclusion formed from this extensive work
is that during the formation of a sheet of paper on a forming fabric s
tructure, density differences are forced to occur. These density diffe
rences are increased during pressing, drying and calendering to the po
int that when a uniform layer of ink is applied to the surface of the
sheet of paper, the ink will penetrate at varying rates depending on t
he density of the sheet at the: point of contact. This variation in pe
netration will result in variations of gloss, offsetting and strike-th
rough to name but a few.
