A processing solution is used to provide flexographic relief printing plates. This solution includes diisopropylbenzene, and one or more organic co-solvents, at least one of which is an aliphatic dibasic acid ester. The processing solution may also include one or more alcohols as co-solvents.

Flexographic processing solution and method of use

A processing solution (or developer) has been designed for use to washout non-polymerized photopolymer compositions to prepare flexographic printing plates having flexographic relief images. This processing solution includes one or more esters of monobasic carboxylic acids represented by one or both of Structures (I) and (II) defined herein and one or more aliphatic or aromatic alcohols.

Flexographic processing solution and use

The present invention involves a method for making a relief image. A film that includes a carrier sheet and an imageable material is used to form a mask image that is opaque to a curing radiation. In one embodiment, the mask image is formed on the carrier sheet while in another embodiment, the mask image is formed on a receptor sheet. The mask image is then transferred to a photosensitive material, such as a flexographic printing plate precursor. The resulting assembly is exposed to the curing radiation resulting in exposed and unexposed areas of the photosensitive material. The carrier sheet or the receptor sheet may be removed from the mask image either before or after exposure to the curing radiation. Finally, the photosensitive material and mask image assembly is developed with a suitable developer to form a relief image.

Method of producing a relief image for printing

The present invention concerns a multi-layer thermal imaging receptor having superior transferability and image color stability for color proofing applications where the images are generated by a laser thermal process. The present invention includes a first support coated by at least, in order, a heat sensitive releasable transfer layer coated, an interfacial bonding layer and an image receiving layer of the present invention adapted to adhere to a second support when heated. The interfacial bonding layer is adapted to enhance adhesion between the heat sensitive releasable transfer layer and the image receiving layer. The present invention further provides a method of making a multi-layer thermal imaging receptor and a method of imaging using the receptor.

This invention is a surface modifying element comprising a photosensitive layer on one side of a carrier substrate. The photosensitive layer comprises a photosensitive binder material and particulates. The invention is also a method of using the surface modifying element to create a receiver having imagewise variation in glossiness.
