Conventional silk printing of non-woven fabrics

some holes of the silk printing plate can pass through the ink and miss printing to the substrate; The holes in the rest of the printing plate are blocked and cannot pass through the ink to form a blank on the substrate. Take the silk as the support, tighten the silk on the frame, and then apply photosensitive glue on it to form a photosensitive plate film. Check whether the grounding device is normal, and then close the positive plate to the plate film for printing. After exposure Development: the parts on the printing plate that do not need to be inked are exposed to light to form a solidified film, which seals the holes and does not penetrate the ink during printing. On the printing plate, it is necessary to briefly describe the materials that can be detected by the friction and wear tester. The holes of the inked parts are not closed, and the ink penetrates during printing, forming black marks on the substrate

non woven bag silk printing features:

1 It is not limited by the size and shape of the substrate. Generally, printing can only be carried out on the plane, while silk screen printing can not only print on the plane, but also on special shaped objects and concave and convex surfaces, but also print all kinds of super large advertising paintings, vertical curtains and curtains

2. The layout is soft and the impression is small. Silk screen printing plate is soft and elastic with small printing pressure, so it can not only print on soft substrates such as paper and textiles, but also on glass that is easy to be damaged under pressure Printing on ceramic vessels

3. Thick ink layer, strong coverage. The ink thickness of silk printing can reach 30 ~ 100 m. therefore, the covering power of the ink is particularly strong, and it can be printed in pure white on all black paper

the ink layer of silk printing is thick, and the graphics and texts printed have a strong three-dimensional sense, which is incomparable with other printing methods

4. Suitable for all types of inks. The wide range of inks used in silk screen printing has gone beyond the definition of ordinary inks. In fact, some are slurry, plastic, paint, adhesive type or solid powder. Therefore, sometimes silk screen printing inks are collectively referred to as printing materials

5. Strong light resistance. In a broad sense, the classification of ink should be divided according to the type of printing plate, that is, relief ink, lithographic ink, gravure ink and filter ink. However, such classification is too principled to express all the reality. In recent years, due to the continuous increase of ink varieties and the continuous emergence of new designs and colors, it has limitations to classify only by edition type.
