A kind of resin ribbon and thermal transfer printing structure

Abstract

The invention belongs to the technical field of carbon ribbon printing, and specifically relates to a carbon ribbon, which includes a tape base, and the two sides of the tape base are respectively covered with a back coating layer and a transfer layer, and the transfer layer includes sols covered sequentially from the tape base to the outside layer, protective layer and carbon powder coating; the sol layer is prepared by mass ratio of the following components: EEA-2615, 60 parts; tackifying resin, 30 parts; AMS resin, 3 parts; SBS, 5 parts; polymerization Wax, 3 parts; the sol layer is bonded between the tape base and the protective layer by thermal processing at a temperature higher than 120°C; the melting point of the sol layer is 120°C-130°C. The resin ribbon described in the present invention can be used in a wide range. Under the action of the print head that can heat up to 130°C, the set sol layer is covered under the printed content during the printing process. protection, so that the printing effect can better adapt to the harsh environment and prolong the duration of the printing effect.

Description

technical field [0001] The invention belongs to the technical field of carbon ribbon printing, and in particular relates to a resin carbon ribbon and a thermal transfer printing structure. Background technique [0002] A barcode printer is a dedicated printer. The biggest difference between barcode printers and ordinary printers is that the printing of barcode printers is based on heat, and the printing is completed with carbon ribbon as the printing medium (or directly using thermal paper). The biggest advantage of this printing method compared to ordinary printing methods The advantage is that it can achieve continuous high-speed printing without supervision. The content it prints is generally the brand logo, serial number logo, packaging logo, bar code logo, envelope label, clothing tag, etc. of the enterprise. The carbon ribbon (ribbon) is the carrier of the toner used for printing. At present, the structure of the carbon ribbon on the market is the same, that is, it i...

AI Technical Summary

Problems solved by technology

Today, more and more printing carriers are appearing, and the traditional toner coating is difficult to guarantee the printing effect and its service life. Therefore, many people have changed the formula of toner coating to ensure that the toner coating It can adapt to different printing carriers and has better display effect

However, simply changing the formula of the toner coating can solve the symptoms but not the root cause. In terms of the current printing effect of the carbon ribbon, it is still prone to the problem that the toner transfer fastness is not high and the color is easy to fade.
