Braille printing technology

Abstract

The invention relates to a braille printing technology, comprising the following steps: professional braille typesetting, that is, the automation of letter input, compilation, typesetting, inspection, collation and even output of the braille in the publishing process is realized through the professional braille and the Chinese characters comparison compilation and typesetting system provided by the Chinese braille computer system; film outputting - the laser typesetting machine is used for putting out the braille symbol in the graphic form; silk screen forme curing - the tension is controlled within 0.8-1.1 (N / cm), the adopted mesh number is 40-60 meshes / centimeters, extrusion coating is 12-16 layers with a 0.2 - 0.5mm thickness; preparing printing ink with uv varnish material and thickener; page making up and adjusting; oil layer extrusion coating; infrared heating and leveling; ultraviolet uv solidifying. The braille printing technology is rapid in print speed, good in printed letters and adhesion of patterns, colorless and transparent, press resistant, wear resistant, low in cost, etc. The braille can be directly printed on reading matters with letters. The double-side printing can be performed and the printing quality is not affected. The ideal braille printing effect can be acquired. The printing can be performed on the ordinary printing materials. The printing carrier of the braille is widened.

Description

technical field [0001] The invention relates to a printing process. In particular, it relates to a braille printing process that can be printed on common substrates and expands the printing of braille on various carriers. Background technique [0002] At present, in Braille printing, Braille printing technologies include: mechanical dotting method, foam ink embossing printing method, dispensing method, and screen printing method. [0003] But there are following deficiencies and problems in the above-mentioned printing technology: [0004] Mechanical dotting method, this kind of printing must use special paper, which is costly; it forms protrusions on the surface of the paper, and ordinary text cannot be added; it cannot be pressed during use; double-sided printing is not possible; the production efficiency is low, and it is easy to wear.

AI Technical Summary

Problems solved by technology

[0004] Mechanical dotting method, this kind of printing must use special paper, which is costly; it forms protrusions on the surface of the paper, and ordinary text cannot be added; it cannot be pressed heavily during use; double-sided printing is not possible; the production efficiency is low and it is easy to wear

[0005] Foaming ink uplift printing method, after printing, the ink needs to be foamed at high temperature, the ink becomes cloudy after foaming, and the text or pattern under the ink cannot be seen clearly; it cannot be pressed heavily during use; the printing time is long; double-sided printing is not possible

[0006] Dispensing method, this printing must use special equipment - dispensing machine, the printing speed is relatively slow, not suitable for mass printing production; this equipment has been initially developed, and there is no mature production equipment in the market at present
