A kind of varnish forming coating transfer printing process

Abstract

The invention relates to a gloss oil forming and coating transfer-printing device. The gloss oil forming and coating transfer-printing device comprises an impressing roller, a printing plate roller, a coating roller, a first coating ink scraping device, a forming transfer-printing roller and a second coating ink scraping device, wherein the printing plate roller and the forming transfer-printing roller are sequentially arranged on the periphery of the impressing roller in a satellite mode; the impressing roller is provided with a working semicircular arc and an intermittent semicircular arc, the radius of the intermittent semicircular arc is smaller than that of the working semicircular arc, and holding teeth are installed at one connection position of the working semicircular arc and the intermittent semicircular arc; the forming transfer-printing roller is made of a transparent material, and a built-in UV curing device is arranged in the forming transfer-printing roller. By the adoption of the transfer-printing device and process, a transparent optical refraction, diffraction and reflection medium with a preset thickness and a preset shape can be obtained accurately on printing stock, and in cooperation with a prefabricated printing stock base drawing, various imaging effects with optical properties are achieved.

Description

Technical field: [0001] The invention relates to the technical field of printing equipment and technology, in particular to a varnish forming coating transfer device and its transfer technology. Background technique: [0002] Rotary printing press (rotary printing press), the printing plate support body and the transfer body are both cylindrical, and are used as a printing machine for rotary motion when the printing process is completed. Existing printing equipment and printing technology generally cannot transfer optical imaging media (especially for optical media of specific thickness and specific shape), so that the visual effect of the substrate is single, and the predetermined optical effect and texture effect cannot be achieved. Invention content: [0003] The object of the present invention is to overcome the shortcomings of existing equipment and processes, and provide a varnish forming coating transfer device and its transfer process. [0004] The technical solut...
