The printing ink layer adhesion rickety, can be divided into three types: the wear resistance is not imprinted staggered; the sun is strongly resist not molecularly imprinted rickety, chemical resistance, not enough imprinted rickety.

1, because of strong surface printing, printing ink layer absorbing substancespenetrate into the capillary structure over printing, resulting in insufficient materialcoating printing ink layer, to protect its links, and then brush to wipe the imprintedpowdering phenomenon.

2, as the semi-finished products, post processing, such as pasting box machine,polishing machine, the face of the opportunities, due to the presence of friction,design printing ink layer, wipe off phenomenon.

3, because the ink layer of sun light or ultraviolet light, in a process environment,prone to fading.

4, because of the printing ink layer chemical resistance and deficiency, imprintingdiscoloration or not firm. When the acid, alkali, salt, soap, oil, printing and packaging of alcohols and chemical exposure, it is easy to present the phenomenon of fading.
