Production of offset thermal transfer paper and transfer method thereof

Abstract

The invention discloses production of offset thermal transfer paper and a transfer method thereof. The method for producing the offset thermal transfer paper comprises the following steps: designing a transfer pattern; separating colors of the pattern by a computer so as to produce each color separating film after color separation; exposing and printing down by each color separating film; producing a color separating printed backplane; and assembling the printed backplane on an offset printer, and separately overprinting the pattern on thermal transfer paper for printing by transfer ink to produce the offset thermal transfer paper. The method for transferring a metal plane sheet comprises the following steps: removing impurities on the metal surface to be transferred, and coating paint on the surface; attaching the surface of the offset thermal transfer paper printed with the transfer ink to the metal surface with a paint film; heating the metal surface to a temperature of between 190 and 200 DEG C by a flat-bed press; pressing the offset thermal transfer paper and the paint film to ensure that the offset thermal transfer paper and the surface of the paint film are attached closely; and peeling off the transfer paper to complete transfer of the pattern after heating and pressing for 33 to 40 seconds. The method for transferring on fabrics is similar to that of on the metal sheet, but paint is not painted.

Description

technical field [0001] The present invention relates to transfer technology, more specifically to the production of offset heat transfer paper and its transfer method. Background technique [0002] Thermal transfer printing is to use special thermal transfer ink to print the pattern on the thermal transfer paper for printing, and then transfer the pattern to the product through temperature and pressure. At present, the production method of thermal transfer paper is: first select or design the required transfer pattern, and use the computer to separate the pattern; then pass the color-separated pattern through the electric engraving machine, and engrave the intaglio or letterpress of the transfer pattern on the plate roller ; Apply transfer printing ink on the version roller, and overprint the pattern color separation on the thermal transfer paper for printing, which is the thermal transfer paper. When transferring, stick the patterned side of the thermal transfer paper on t...

Problems solved by technology

Due to the use of electro-engraving plate making on this kind of thermal transfer paper, the printed pattern is rough and not delicate, the layering is poor, and the engraving time is long
