Document Summary

In any printing process, it is the purpose of the ink to impart the information by producing an image on a substrate. A traditional definition of an ink is a combination of pigment/dye, binder precursor and/or film former and/or curable monomer r and solvent, assembled in such a way as to produce a near homogenous composition. The method of drying for these types of inks is by evaporation of the solvent from the ink film. Uv drying technology: advantage is that they dry extremely rapidly on exposure to uv radiation, undergo no drying prior to and during printing, and release no volatile organic compounds into the air. In- line presses: each print unit following the next in a line: can run either sheeted material or reels, popular set-up in the packaging market. Central impression (ci) presses: each unit distributed around one central impression cylinder, tend to be web fed, take us less floor space than in-line presses.
