International Classification:

G03F 7/00
B41N 7/00

US Classification:

430306, 430935, 1014631

Abstract:

A method and apparatus for preparing a relief printing form from a photosensitive element that includes a photopolymerizable composition layer having an exterior surface and capable of being partially liquefied. The method includes the steps of (a) heating the exterior surface of the photopolymerizable composition layer to a temperature sufficient to cause a portion of the layer to liquefy, forming the liquefied material; and (b) removing the liquefied material; wherein the heating step is performed using vibrationally-induced frictional energy.

International Classification:

B41F 21/00

US Classification:

1014151, 1013821

Abstract:

A method and apparatus of securing and tensioning a printing form in an apparatus having a rotatable drum includes securing a first portion of the printing form to a first means for receiving that is coupled to a surface of the drum, and securing a second portion of the printing form to a second means for receiving that is disposed on a rotatable member that extends over a portion of the drum. The rotatable member is rotated so that the circumferential distance between the first receiving means and the second receiving means is about the same as a length of the printing form. A rotary torque means is coupled to the rotatable member to apply a substantially constant torque on the member and tension the printing form about the surface of the drum. The rotary torque means adjusts torque on the member which adjusts tension on the printing form.
