The difference between printing and screen printing
Printing through a silicone rubber cast steel intaglio printing head graphic (or sensitive adhesive gravure) on transfer printing onto substrates, can be used for a variety of flat or molded printing, such as glass, plastic, metal products, watches and electronic, optical products. Its main feature is available for irregular shaped convex surface printing. These print using other printing methods are difficult can not even complete, but can be easily accomplished using the pad, and to achieve multi-color fine print. This apparatus, equipment and surface printing small products, it is ideal for printing.
    Printing and screen printing has many similarities, such as wide adaptability of substrates; a wide range of inks, printing inks and screen printing ink basically universal; can easily be done by replacing the fixtures and different plates printing and other products. So, in many occasions pad printing and screen printing as a pair of twin sisters intimate, special printing technology jointly play an important role. Because of this, many experts regard the pad printing classified to the field of screen printing, pad printing without subdivision specialized technical and research institutions. However, printing and screen printing characteristics and use of technology still have some differences. First, from the point of view of the ink transfer process, printing and screen printing has significant difference; printing machine and a network printer is not the same structure; product range and screen printing printing technology adaptation is also very different. From the objective point of view, the difference between printing and screen printing is much greater than the similarities between them, but the reason they are tied together accustomed to, even more important reason is the printing and screen printing are faced with a common The market, in this common market, is inseparable from the printing screen printing. Stripped from the screen printing industry, printing more difficult, but also no need, but to understand printing technology can not only by screen printing industry eyes to look at it.
To sum up, printing features are:
(1) suitable for flexographic printing, resilient silicone rubber printing head other than the plane of the complex shape of the substrate two, three curved and irregular surfaces, etc. can be printed;
(2) can print finer illustrations, generally of 0.05 mm thin printing;
(3) Printing stable and sustainable, even after prolonged printing, the printing accuracy will not change;
(4) eliminating the drying step, continuous multi-color printing;
(5) The wide range of substrates available in plastic, metal, glass, ceramics, leather, and other materials, products, bakelite any uneven surfaces accurately printing monochrome, color and color graphic, but also for soft contact printing , but also for print in soft goods (such as fruit, pastries, eggs, etc.) as well as the fragile fragile items (such as ceramics, glass products, etc.);
Easy to learn and reliable (6) printing process operation, no special esoteric techniques.
Silk screen process after the ink through the screen mesh drain portion printed on the substrate, the rest of the screen mesh is clogged, the ink through, however. This formed part of the more gaps in the substrate. When printing ink down on the screen, in the absence of external force ink does not leak through the mesh themselves to the substrate, and when the blade at a certain pressure and tilt angle scraping ink, it will be transferred through the network version to the underlying substrate in order to achieve a copy image.
Screen has the following characteristics:
1, the substrate wide: As the plate using a screen made of soft and elastic, so the substrate, whether flat or curved, hard or soft, big or small can be printed. In addition, because of the small screen can also be printed on the fragile pressure deformable substrates.
2, ink thickness and hiding power: screen printing ink thickness, unmatched by other printing methods. As covered with white background below, the use of ordinary printing method requires India 3-4 times at the same site, and can be implemented with just one screen. Screen printing ink thickness of 20 microns up to 100 microns thick film printing special, thinnest and 6 microns. So printing ink thickness and large adjustable range.
3, strong three-dimensional sense: Since the ink layer thickness, so results when copying prints and painting imitation is very realistic, much more than its color offset printing; but in the fine print pattern of reproduction are subject to certain restrictions.
4, the light is good: later transferred to light pigments and fluorescent pigments in the ink, print pattern can permanently maintain luster without the air temperature and sunlight, even glow in the night. Therefore, silk screen products suitable for outdoor advertising, signs and so on.
5, the ink rather broadly applicable: water-based, oil-based, solvent-based, etc., can be used even slurry, paste, powder, so the printing ink printed material referred to.
6, large format: the printing area, the general offset printing, letterpress and other methods due to the limitations of mechanical equipment and far less than the screen. Most large format printing has reached 3M * 4M even bigger.

7, the plate has a greater scalability: Feature screen material determines the plate will have greater flexibility. When used in high-volume printing, easily stretched plate will affect the replication of results.
