Problems solved by technology

The flexographic plate processed by this method has seam problems during printing, and it is impossible to print continuous and seamless patterns, resulting in great printing limitations
At the same time, since the printing should avoid the seam of the plate roller, some patterns need to avoid the seam when arranging some patterns, which will cause waste of raw materials

Abstract

The invention discloses a seamless flexible plate making technology. The seamless flexible plate making technology comprises 1, coating a flitch plate sleeve roller as a base roller with black rubber and carrying out processing through a grinding machine to obtain a rubber layer with thickness of 7-10mm, 2, preparing a carving file according to requirements and inputting the carving file into carving software of a carving machine, 3, inputting actual sizes of the rubber roller into the carving machine, introducing the carving file and carrying out pattern graving on the rubber roller, and 4, preparing a seamless flexible printing plate according to characteristics of diameter error automatic scaling and automatic circumferential joint through the laser carving machine. The seamless flexible plate making technology solves flexible plate joint problems and improves printing adaptability.

Description

technical field [0001] The invention relates to printing technology, in particular to a manufacturing process of a seamless flexographic plate. Background technique [0002] Flexo printing is a form of direct printing, called flexo printing due to the use of elastic, raised image plates. The existing common flexographic plate is manufactured in the flat plate type, and the finished flexographic plate is a silicone plate with a thickness of about 3mm. The customer needs to use double-sided adhesive tape to stick the silicone plate on the plate sleeve roller for use. The flexographic plate processed by this method has seam problems during printing, and it is impossible to print continuous and seamless patterns, resulting in great printing limitations. At the same time, since printing should avoid the seams of the plate rollers, it is necessary to avoid the seams when arranging some patterns, which causes waste of raw materials. Contents of the invention [0003] The object...
