Talking about the function and identification of powder spraying in offset printing

Powder spraying is an indispensable process in the modern high-speed multi-color Offset Printing process.

The main function of powder spraying is to prevent the back of the printed matter from being dirty and improve the printing quality and efficiency. The powder spraying is made of pure natural plants and refined by modern science. The powder particles are spherical, crystal clear, and the surface is smooth (particle size 10 ~ 25μm). Special surface treatment of micro-particles, excellent dispersibility and fluidity, prevent reverse printing, no hardening, no clogging, not only give full play to anti-sticking and anti-static effects, but also do not affect the printing effect and the transparency of the film, but also have excellent Water resistance, no clumping with temperature and humidity; improve the four main technical indicators of ink (drying performance, transfer performance, drying speed, post-printing suitability) as the premise to improve the quality of printing and ensure the post-printing process Smoothly. It can make the ink dry quickly, the powder is thoroughly fused, and the anti-backprint effect is particularly prominent. It can more perfectly express the exquisiteness of high-end product printing, making the subsequent processing (such as peritoneum, glazing, etc.) more perfect; suitable for various printing materials And powder spraying device.

Among them, the printing powder spraying is an indispensable tool in offset printing, and its main function is to prevent the printed matter from sticking to the back of the printing process and accelerate drying. Good Powder Spray particles are smooth, excellent in assimilation with ink, and evenly distributed after spraying, which is of great help to improve printing quality and printing efficiency! Widely used; except for color printing, this product can be used for film, rubber, nylon, composite. The powder particles are spherical; the surface is smooth; the particle size is 10 ~ 25μm (mesh number is 300 ~ 450); the powder particles are uniform; the fluidity and spreadability are excellent; the assimilation with the ink and the lipophilicity are particularly good. It can be completely and evenly distributed on the surface of the printed product, so that the printing quality can be well guaranteed.

Containing mixed solvent,ultrafine abrasive sand,strong decontamination (scratch, dirty, dirty stain and various oxide). Improve the non-image area doesn`t sense grease, form good hydrophilic film. While removing the ink, improve the image area sense grease. Various plate (Ps Plate, CPT plate, aluminium plate, zinc plate, etc) can be use.
