How about a plateless bronzing machine?

Hot stamping process is a special printing process. The main difference between the plateless bronzing machine and the traditional bronzing machine is that it does not need plate making, and can be used for stamping paper, film, leather, cards, signs, cloth, ribbons and other materials, which is more convenient than the traditional bronzing machine. There are many stamping methods for plateless stamping machine, including sublimation method, migration method and melting method. Let's take a look at Bian Xiao. How about a plateless bronzing machine?

1, which is different from traditional bronzing machine.

No-plate bronzing machine This bronzing machine does not need to make zinc plates, typeset them on the computer and then print them. Traditional bronzing machines all need plate making. The plate-making mentioned here is to make a zinc plate, make the content that needs ironing into a template, and then print it directly. No-plate bronzing adopts computer typesetting and direct printing, which is convenient and fast.

2. Features of plateless bronzing machine

Brand-new digital flat bronzing equipment subverts the shortcomings of traditional plate-making bronzing process, such as complex and long cycle, and truly realizes instant bronzing and instant completion. It can be used for hot stamping, computer typesetting and screen output of paper, film, leather, cards, signs, cloth, ribbons and other materials. The starting point and pressure of hot stamping can be adjusted at will.

3. Scope of application of plateless bronzing machine

High-end graphic hardcover bidding, printing, business card printing, signs, images, gifts, personalized greeting cards, celebrations, Spring Festival couplets and other industries. Paper, PVC card, leather, post-it notes, cloth, coated paper, binding paper, adhesive.

What are the methods of digital plateless bronzing machine?

1, sublimation

The ink is used for bronzing and consists of disperse dye, water-soluble carrier or alcohol-soluble carrier and oil-soluble resin. It is required that the molecular weight of the disperse dye is 250-400 and the particle size is 0.2-2 microns. At the temperature of 200-230 degrees Celsius, the disperse dyes are transferred to synthetic fibers after 20-30 seconds of treatment by automatic digital plateless bronzing machine.

2. Swimming method

Firstly, the fabric was impregnated with mixed liquid for gravure printing, then it was transferred by hot pressing in wet state, so that the dye was transferred to the fabric and fixed, and finally it was steamed and washed with water.

3. Melting method

Ink is embedded in the fabric by melting and pressing the digital printer. And then the subsequent treatment is carried out according to the properties of the dye. Generally, a lot of pressure is needed, and the greater the pressure, the better the effect.

Working principle of digital plateless bronzing machine

Digital plateless bronzing machine does not need to make zinc plate, which is more convenient and can save plate making cost. The essence of hot stamping is transfer printing, that is, the process of transferring the pattern on hot stamping paper to the surface of the substrate through the action of temperature and pressure. The core technology of plateless bronzing machine is the printing head, and the hot stamping point is realized by the printing needle. Therefore, the plateless bronzing machine is actually the performance of gathering countless bronzing points, similar to the resolution of a computer screen. The smaller the hot stamping point, the smoother the text edge and the finer the hot stamping image, just like the pixels of digital photos, so the plateless bronzing machine is also called digital bronzing machine.

When digital plateless bronzing machine is used for hot stamping, the adhesive layer of bronzing paper melts and forms adhesion with the substrate surface. At the same time, the silicone resin flow in the release agent of gilding paper is separated from the carrier film, and the pictures and texts on the carrier film are transferred to the substrate. The reason why it can be transferred is that the hot melt adhesive produces cohesion when heated, while the adhesive force of the release agent disappears when heated. Hot stamping can adapt to most substrates, especially paper, plastic and wood.
