International Classification:

G03F 7/00
G03F 7/26
G03C 1/00

US Classification:

430306, 4302811

Abstract:

A pattern of ink is printed on a substrate, such as corrugated paperboard with a relief printing form made from a photosensitive element. An in-situ mask is formed for the photosensitive element, the element is exposed to actinic radiation through the in-situ mask in an environment having an inert gas and a concentration of oxygen between 190,000 and 100 ppm, and the exposed element is treated to form the relief printing form having a pattern of printing areas. Printing is accomplished by securing the relief printing form to a print press, applying the ink to the printing areas on the printing form, and contacting the ink from the printing areas to the substrate to transfer the pattern of ink onto the substrate.

US Classification:

430306

Abstract:

A relief printing form is prepared from a photosensitive element in an environment having controlled oxygen concentration during exposure to actinic radiation. An in situ mask is formed on a photosensitive element, the element is exposed to actinic radiation through the in-situ mask in an environment having an inert gas and a concentration of oxygen between 190,000 and 100 ppm, and the exposed element is treated to form the relief printing form having a pattern of raised surface areas.

International Classification:

G03C001/76

US Classification:

430/204000

Abstract:

A photosensitive element for use as a flexographic printing plate comprises a support, an elastomeric photopolymerizable layer having a surface opposite the support that defines a plane, and a matted layer disposed above the surface of the photopolymerizable layer comprising a polymeric binder and at least one matting agent which is capable of forming depressions from the plane into the photopolymerizable layer. Also described is a process for preparing such a photosensitive element and a process for preparing a flexographic printing plate from the photosensitive element.
