Non-impact transfer printing method and device therefor

Abstract

The invention discloses a non-plate transfer printing method and an apparatus therefor. The apparatus comprises: a non-plate transfer paper with a PVC plastic paper on its base layer, a pattern layer above the PVC plastic paper and sequentially provided with a resin type releasing agent, an anti-solvent transparent ink, a full-color image, a white ink, and a print hot transfer glue; a press transfer machine to provide vacuum, pressurizing and a thermostatic environment with a temperature of 75~120 centigrade, wherein the press transfer machine has a special plastic material mould turning jig to hold and fix a transferred object, the non-plate transfer paper is disposed above the transferred object and coated with a silica gel layer evenly to fix the surface force bearing, so that the non-plate transfer paper can evenly reach to the vertical corners to perform transfer printing. The invention can obtain a pattern with high solution without damnifying a notebook computer casing, and can perform transfer printing at low temperature.

Description

technical field [0001] The present invention relates to a transfer printing device, in particular to a plateless transfer printing method and its device, which are applied to transfer high-resolution patterns to the casing of a notebook computer, showing a unique personal style. Background technique [0002] In the past, the exterior of a product, such as a computer case, such as the case of a laptop computer, has been decorated with a graphic design that forms a three-dimensional space on the case of the computer itself. These designs can be printed or dyed. In the past, it was difficult to transfer or dye images directly on plastic items, such as acrylonitrile-butadiene-styrene (ABS) product casings. The temperature required for transferring the image and dyeing it onto such a surface is so high that the shells themselves will melt, so there will be errors in the color, and the resolution cannot be overcome due to the temperature relationship, thus making the color patter...

Problems solved by technology

In the past, it was difficult to transfer or dye images directly on plastic items, such as acrylonitrile-butadiene-styrene (ABS) product casings

The temperature required for transferring the image and dyeing it onto such a surface is so high that the shells themselves will melt, so there will be errors in the color, and the resolution cannot be overcome due to the temperature relationship, thus making the color pattern Unable to copy the surface appearance of ABS products

Due to the traditional printing on uneven plastic surfaces, the heat-resistant thermal transfer printing technology has matured, but it will cause obstacles when applied to materials that are not resistant to high temperatures, resulting in color difference and blurring of printing, but as long as the temperature is slightly increased, it will change. Causes damage to the surface of the transferred object
