摘要:
Disclosed are a printing plate and a mirror thereof, the printing plate including: printing portions for transferring an immersed solution, the printing portions being formed flat and arranged at regular intervals on one side of an upper part of the printing plate; and non-printing portions corresponding to a remaining area other than the printing portions, the non-printing portions being formed with at least two concavities and convexities respectively and arranged at regular intervals on the other side of the upper part of the printing plate.

Disclosed is an environment friendly waterless offset plate. The waterless offset plate is formed by: coating a base coating on a surface of a metal plate substrate not subject to electrolytic graining and/or anodic oxidation treatment but subject to oil-removal solution immersion, coating a diazonaphthoquinone light-sensitive adhesive layer on a surface of the base coating, coating an ink-repulsive layer on a surface of the diazonaphthoquinone light-sensitive adhesive layer, and further covering a polymer protective film on a surface of the ink-repulsive layer. The waterless offset plate has a good printability, and has a pressrun up to 10 to 30 thousand copies.
摘要:
A printing member such as a printing cylinder includes an at least partly metal cylinder, or a sleeve to be mounted on a mandrel rotating about its axis. The printing member comprises a body having a thickness. With the printing member there is associated an activatable signaling device that is connectable to a recording device that is arranged to store data related to at least one characteristic of the printing member or to the use of the printing member. The activatable signaling device can include a transponder such as an RFID.
摘要:
The invention concerns a printing plate in the form of a roller and a method for obtaining same. Said method consists in producing on a first layer, at least a photopolymer film and in coiling said layers on themselves to form a roller. The invention is applicable in flexographic or typographic printing.
摘要:
A lithographic printing plate substrate is conditioned for imaging in a printer engine by an edge protector adhered along at least one edge of the plate substrate, the edge protector being of a flexible material, being coextensive with the edge, having face portions adhered to portions of the opposite faces adjacent the edge, and having an edge portion overlying the edge.
摘要:
A ceramic layer comprising aluminum oxide and a silicate compound is applied to a substrate of a printing plate, with the silicate compound acting as a binder to ensure adhesion of the ceramic layer to the substrate.
摘要:
This application provides an alignment film transfer printing plate including a substrate, a first dot arranged on the substrate, and a plurality of second dots arranged around the first dot. A height of each of the second dots in a direction perpendicular to a surface of the substrate is less than or equal to a height of the first dot in the direction perpendicular to the surface of the substrate, a blocking portion is formed on an end of the first dot away from the substrate, and an area of an end surface of each of the second dots away from the substrate is less than an area of an end surface of the blocking portion away from the substrate.
摘要:
An ink image is formed on the side of a gauze of a screen master by discharging ink by an ink discharge apparatus, and collected visible rays or infrared rays are irradiated onto the ink image to heat the ink. Then, a thermoplastic resin film is perforated to form a plate making image corresponding to the ink image. The minute ink drops discharged from the ink discharge apparatus are held inside minute opening portions (pixels) of fibers configuring the gauze, and are put on the thermoplastic synthetic resin film bent by gravity. Thermosensitive perforation is carried out in this state, and thus a high-definition plate making image corresponding to the image configured using the ink drops in units of pixels can be obtained.
摘要:
A system and method of preparing a flexoplate so it is suitable for the printing of high resolution patterns. The method includes controlling the curing conditions of the flexoplate, thereby controlling the properties of said flexoplate such as floor thickness, pattern cross-sectional geometry, repeatability of printed features during the printing process, and durability of the flexoplate during the printing process.
摘要:
Disclosed is a resin composition for laser engraving, comprising (Component A) an oligomer or polymer having a (meth)acryloyloxy group in the molecule, (Component B) an ethylenically unsaturated compound, (Component C) a compound having in the molecule at least one type selected from the group consisting of a mercapto group, a primary amino group, and a secondary amino group and at least one type of hydrolyzable silyl group and/or silanol group, and (Component D) a thermopolymerization initiator.
