Abstract
The invention relates to a form for the rotary machine printing, coating or imprinting of web-shaped materials and a method of producing the form wherein at a carrier having a cylindrical surface area an elastomer layer is attached which after curing at the outer circumference thereof is machined and engaged to result in a cylindrical shape. Furthermore the invention is characterized in that the elastomer layer is formed of a hot cure single-constituent or two-constituent silicone polymer.
Claims27
A method of manufacturing and using a form for flexographic printing, the method comprising the following steps:
- providing a carrier having a cylindrical outer surface;
- coating the cylindrical outer surface of the carrier with an elastomer layer comprising a hot cure material, the hot cure material being at least one of a one-component and a two-component silicone polymer;
- applying heat to the elastomer layer;
- curing the outer surface of the elastomer layer through said application of heat;
- machining the outer surface of the elastomer layer;
- engraving the outer surface of the elastomer layer;
- and
- using the resulting form in a flexographic printing process.
A method of manufacturing and using a form for flexographic printing, the method comprising the following steps:
- providing a carrier having a cylindrical outer surface;
- coating the cylindrical outer surface of the carrier with an elastomer layer comprising a hot cure material when the elastomer is in a liquid state, the hot cure material being at least one of a one-component and a two-component silicone polymer;
- applying heat to the elastomer layer as the elastomer layer is coated onto the carrier;
- curing the outer surface of the elastomer layer through said application of heat;
- machining the outer surface of the elastomer layer;
- engraving the outer surface of the elastomer layer;
- and
- using the resulting form in a flexographic printing process.
