These coatings are characterized by the type of reaction they undergo upon exposure to UV light: A well known example of a photopolymer coating is Kodak Photo Resist (KPR), a photo cross-linking polymer, which is used in image carrier preparation for all major printing processes as well as in the preparation of printed circuit boards. Join the world's largest stamp collecting organization | Exclusive benefits! Image carriers produced by this method are used in lithography, gravure, and screen printing. Conversely, offset plate costs are minor from $1,500 to $2,500 when amortized across the complete press run, allowing you to make the most of versioning for different list segments. Why are projects moving away from offset? Traditionally, rough layouts and paste-ups were composed by hand using: The text used in the paste-up was typeset and printed mechanically. The bichromate of choice is ammonium bichromate, with potassium bichromate used in special processes such as collotype. Whether you choose a gloss, silk or matt finish is mostly down to your personal preference, although gloss paper will produce the most vibrant color reproduction. Thanks, Graeme.
