Preparation method for compounded thermal transfer ribbon

Abstract

The invention discloses a preparation method for a compounded thermal transfer ribbon. The compounded thermal transfer ribbon comprises a ribbon base, wherein one surface of the ribbon base is coated with an ink layer; the other surface of the ribbon base is coated with a heat-resistant coating; a bonding material, a coloring agent, a filling material and an auxiliary are fully mixed and dispersed, so that an ink layer coating solution is obtained; the front surface of the ribbon base is coated with the ink layer coating solution through a coating machine; the back surface of the ribbon base is coated with the raw materials of the heat-resistant coating through the coating machine; the surface, to which the heat-resistant coating is attached, is in contact with a printing head; the ink layer is in contact with a label; and during operation, the printing head generates heat, and the ink layer is molten and stamped onto the strip-shaped or card-shaped label through the heat-resistant coating, so that clear characters and images are formed. Compared with the prior art, the compounded thermal transfer ribbon has higher scratch resistance, durability and solvent resistance, and in addition, can be well applied to strip-shaped or card-shaped labels with small areas, and the printing temperature is low by adopting the compounded thermal transfer ribbon disclosed by the invention, so that equipment is protected effectively.

Description

technical field [0001] The invention belongs to the technical field of preparation methods of thermal transfer ribbons, and in particular relates to a preparation method of composite thermal transfer ribbons. Background technique [0002] Thermal transfer ribbon is a necessary consumable material for thermal transfer printing, and it is also the core material that determines the quality of thermal transfer printing. Thermal transfer ribbon transfers the ink layer on the ribbon to the plastic through heat and pressure. It is a kind of printing consumables on materials such as paper, composite film, etc. It uses temperature and pressure to dissolve the ink on the ribbon, and then hot stamps the ink on the label. It is suitable for printing identification and marking information such as production date, batch number, and weight. , can achieve clear printing of characters, and the printed handwriting has the characteristics of clear, firm, scratch-resistant, and cooking-resistan...

Problems solved by technology

However, the wax-based thermal transfer ribbons in the prior art have poor scratch resistance and durability, and also have disadvantages such as poor solvent resistance and insufficient printing clarity, and cannot be well realized in ribbons or card shapes.
