Ink knowledge small encyclopedia big exposure! Reveal the secret weapons of the printing industry!

Ink is a key material in the printing industry, which is transmitted to the printing material through the printing press to form graphic printing. The role of ink is not only to transmit patterns and text, but also to enhance water resistance, UV protection, increase color saturation and other functions. Here will reveal some basic knowledge about ink and some secret weapons.

First of all, we need to understand the composition of the ink. Inks are usually composed of pigments, resins, solvents and auxiliaries. Pigments are the color basis of the ink, resins are curing agents, solvents are used to dilute the ink and make it easy to print, additives are used to enhance ink properties and printing effects. Different ink types have different formulations to suit different printing needs.

The main categories of inks include offset inks, gravure inks, letterpress inks and screen inks. Offset printing ink is a widely used type of ink that is transferred to the printing material through the blanket of the printing press. Gravure ink is suitable for gravure printing machines, and the excess ink is scraped off the gravure template by a scraper, leaving only the ink of the pattern part. Letterpress inks are suitable for letterpress printing and transfer the ink to the printing material through the raised pattern on the printing template. Screen ink is suitable for screen printing, and the ink is transferred to the printing material through the holes in the screen.

Next, we will introduce some ink secret weapons. First, the ink can adjust its color and luster. By adjusting the type and proportion of pigments, the ink can show different colors and effects. For example, metallic pigments can give the ink a metallic texture, and reflective pigments can increase gloss. Secondly, the ink can add some special effects, such as light-emitting ink, color-changing ink and scented ink. Luminous inks can fluoresce in a dark environment, color-changing inks can change color with temperature changes, and scented inks can emit a variety of fragrances.

In addition, the ink can also be applied to some special printing needs. For example, anti-counterfeiting ink can increase the anti-counterfeiting of the product, concave and convex ink can increase the texture of the print, and anti-pollution ink can prevent the print from being polluted. These special inks play a key role in protecting product safety and improving print quality.

Finally, there are some environmentally friendly inks worth paying attention to. With increasing environmental awareness, many printing companies are starting to use low volatile organic solvents (VOC) and renewable materials to produce inks to reduce their environmental impact. These environmentally friendly inks play a positive role in reducing the emission of harmful substances and the sustainable use of resources.

In summary, ink is the secret weapon of the printing industry. It provides rich color, texture and function to prints by adjusting formulations and adding special effects. In the context of increasing environmental awareness, the development and application of environmentally friendly inks has also become an important trend in the printing industry. By understanding the composition and classification of inks, we can better understand the secret weapons of the printing industry and provide more possibilities for the design and production of printed matter.
