Thermal Transfer Ribbon structure
Thermal Transfer Ribbons as a printed material The structure from the surface is composed of three parts, namely the surface material, adhesive and the end of paper. Selection of the surface material of the Thermal Transfer Ribbon must be based on the use of the Thermal Transfer Ribbon environment and treatment.
Then the Thermal Transfer Ribbon surface material, is a positive acceptance of printed graphics, the back of the adhesive and eventually applied to the paste on the material. Facing to be able to adapt to printing and printing, with good ink, and have enough strength to accept a variety of processing, such as die cutting, waste, slitting, drilling and labeling.
In general, all flexible materials can be used as a Thermal Transfer Ribbon of fabric, such as commonly used paper, film, composite foil, all kinds of textiles, thin metal and rubber and so on. The type of surface material depends on the final application and the printing process.
Tape structure from the surface point of view is composed of three parts, namely, surface materials, adhesives and the end of paper, but from the manufacturing process and ensure the quality of the point of view, the Thermal Transfer Ribbon consists of seven parts.
1, surface coating
Used to change the surface properties of the surface material. Such as improving the surface tension, changing the color, increasing the protective layer, etc., to better accept the ink and easy to print, to prevent dirt, increase ink adhesion and prevent the purpose of printing graphics off. Surface coating is mainly used for non-absorbent materials, such as aluminum foil, aluminum paper and various types of film materials. Surface coating strength determines whether the printing will produce a lot of paper powder, but also determine the printing quality of the important indicators.
2, surface material
That is, the surface material, is a positive acceptance of printed text, the back to accept the adhesive and eventually applied to the material on the paste. In general, all flexible materials can be used as a Thermal Transfer Ribbon of fabric, such as commonly used paper, film, composite foil, all kinds of textiles, thin metal and rubber and so on. The type of surface material depends on the final application and the printing process. Facing to be able to adapt to printing and printing, with good ink, and have enough strength to accept a variety of processing, such as die cutting, waste, slitting, drilling and labeling. Surface surface gloss and color consistency, density uniformity of some indicators determine the uniformity of the Thermal Transfer Ribbon ink, but also determines the same batch of Thermal Transfer Ribbon printing products of color.
3, the bottom of the coating
Its surface coating with the same, but is coated on the back of the surface material, the main purpose of the bottom layer is:
(1) to protect the surface material, to prevent the adhesive penetration.
(2) increase the opacity of the fabric;
(3) increase the adhesion between the adhesive and the same material;
(4) to prevent the plastic surface material in the plasticizer penetrate into the adhesive, affecting its adhesive performance, resulting in reduced adhesion of the Thermal Transfer Ribbon, Thermal Transfer Ribbon off.
The adhesive is a medium between the Thermal Transfer Ribbon material and the bonding substrate. According to its characteristics can be divided into permanent and removable two. It has a variety of recipes, suitable for different face materials and different occasions. Adhesive is the most important component of Thermal Transfer Ribbon technology, is the key to the application of Thermal Transfer Ribbon technology.
5, from the type coating (coated silicon layer)
That is, in the bottom of the paper coated with silicone oil layer, coated with silicone oil can make the end of the paper surface tension is very low, very smooth surface, the role is to prevent the adhesive bonding at the end of paper.
6, at the end of paper
The role of the end of the paper is to accept the release agent to protect the back of the adhesive material, support the surface material, so that it can die cutting, waste and labeling on the labeling machine. As with the surface material, the uniformity and strength indication of the thickness of the base paper are not only related to the printing performance, but also to determine the uniformity of die cutting and the important index of the velocity and the edge of the paper.
