JPH01299100A - Plate with embossed expression of character or pattern - Google Patents

Abstract

PURPOSE:To obtain a projected expression of clear desired characters or patterns on a plate through a simple and speedy operation, by baking an ink on the surfaces of characters or patterns provided in a projected form by a photopolymer plate making process, thereby expressing the characters or patterns. CONSTITUTION:A known photopolymer plate making process is applied to a photosensitive hardenable resin layer 3 by irradiating with light through a negative film or the like, and an ink 2 is baked thereon, whereby clear characters or patterns 1 are expressed and adhered to a substrate, resulting an expression on a plate. By only performing the photopolymer plate making process comprising the steps of taking a picture of the desired characters or patterns to form the negative film and irradiating the photosensitive hardenable resin layer with light through the negative film, a photo-crosslinking reaction is also effected with the result of satisfactory hardening in a short time, and the characters or patterns are easily provided in a projected form. This effect, together with the brightness of the ink, makes it possible to easily obtain a plate or the like comprising clear characters, patterns or the like expressed on a substrate.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a plate on which characters and patterns are expressed in a protruding manner. Specifically, after the characters and patterns are expressed by photosensitive resin letterpress processing, ink is applied. This relates to a plate with a single character and pattern printed on it to clearly express it.

[Conventional technology]

BACKGROUND ART Conventionally, in order to obtain a plate on which a desired character or pattern is expressed in a protruding manner on a metal plate, the plate is produced by forming the character or pattern in a protruding manner by methods such as engraving, etching, or pasting.

[Problem to be solved by the invention]

However, as is well known, the above-mentioned conventional method.

All of them involved problems that were expensive because they required advanced technology and a lot of effort.

The present invention has been made in view of the above-mentioned problems of the conventional technology, and its purpose is to easily and quickly produce a plate that clearly expresses desired characters and patterns. This is what we are trying to provide.

[Means to solve the problem]

In order to achieve the above object, the plate in which characters and patterns are prominently expressed in the present invention is produced by applying a photosensitive resin letterpress treatment to the surface of the photosensitive cured resin layer.

A desired character or pattern is formed on a single protuberance, and ink is baked onto the surface of the protrusion to clearly express the character or pattern, and a photosensitive resin layer is attached to the substrate.

[For production]

The photosensitive cured resin layer is exposed to light through a negative film, etc. and subjected to a known photosensitive resin letterpress process, and the ink is baked on to create clear letters and patterns, which are then attached to a substrate to be printed on the plate. Ru.

〔Example〕

Examples will be described with reference to the drawings.

In FIGS. 1 and 2, l is the photosensitive cured resin layer 3 [for example, APR% manufactured by Asahi Kasei Corporation or D
ycril or BASF's Nyloprint
etc.] is irradiated with light through a negative film and subjected to a known photosensitive resin letterpress process using wax, Shuaud liquid, etc., and letters and patterns are printed with protruding letters and patterns formed by protruding depressions. 2 is ink baked on the surface of the protruding characters and pattern 1. 4 is a substrate attached to the lower surface of the photosensitive cured resin layer 3 via an adhesive 5. The substrate 4 is preferably a metal plate, but may be made of ceramic,
It can also be made from wood boards. Furthermore, when ink 2 is an ultraviolet curable ink that is baked, letters and patterns with even better glitter can be obtained.

〔Effect of the invention〕

Since the present invention is configured as described above.

This produces the following effects.

All you have to do is copy the desired characters and patterns onto a photograph, make a negative film, expose the photosensitive hardened resin layer to light, and perform the known photosensitive resin letterpress process. A photocrosslinking reaction will also occur and the film will be fully cured in a short period of time. It is easy to form protruding letters and patterns, and combined with the brightness of the ink, it is easy to obtain plates with clear letters and patterns on the substrate, so it is a good idea to attach it to a key chain, etc. This invention is most suitable for convenient car license plates, ornaments, reproductions of miniature chairs, etc.
