Pad printing through the role of the rubber head will be inscribed on the design of sheet metal is transferred to the workpiece, similar to the daily work of sealed by glue head pressure will design printing to printing, screen printing is the pressures to the stencil printing ink from the screen mesh to infiltrate products, form a pattern.
There is no limit to the pad printing on the product shape, flat, surface, surface waves, as long as is where the rubber head deformation can be reached all can printing ink is easy to dry.To increase output and reduce labor costs.The corresponding profits for the enterprise.Screen printing products printing and surface smooth, flat surface or surface.High printing quality.
Pad printing machine can be on a single machine is used for up to six tinted, one-time printed products, and lower cost, suitable for general investment screen printing machine factory also can do multi-color overprint, but price of multi-color overprint of screen printing machine is very high, not suitable for general factory investment, manual catwalk one-time multi-color overprint covers an area of big, artificial.Ink is not easy to do.
2. The characteristics of screen printing and pad printing
Pad printing ink layer thinner, can be in any surface printing color, showing very good color expressive force and printing adaptability, commonly known as the universal printing, any objects are available on printing printing screen printing ink layer thickness, print out the patterns of the stereo sense is strong, with the hand can touch the AoTuGan, suitable for high-end products on the surface of printing, color expressive force is very good, more trouble multi-color overprint, on the surface of the product requirements are rules of flat or curved surface, there are certain limits of printing limitations
Sum up, the characteristics of the pad printing mainly include:
(1) suitable for special printing, can be in as long as the glue on the side of the flat surface of the product can print head can touch place.
(2) can print the detailed graphic, general can printing fine line 0.05 mm;
(3) printing and stable, even if long time printing, the printing accuracy will not change;
(4) get rid of the drying process, can be continuous multi-color printing;
(5), gives a wide range, can be in plastic, metal, glass, ceramics, leather, stationery, toys, computer components, automobile interiors, etc all kinds of material products is concave and convex surface accurately for monochrome, double color and color graphic printing, you can also print fragile fragile items (such as ceramic, glass products, etc.) on a printing;
(6) pad printing process and easy operation.
Screen printing technology is part of the ink through the screen mesh after printing on substrates, the rest of the screen mesh of blocked, ink penetration.This part of the form blank on the substrates.When printing ink on the screen, in the absence of external force under the action of ink through the mesh themselves leaking into the substrates, and when the scraping board at a certain pressure and Angle motion ink, it is transferred to the following through the screen mesh to achieve image printing on substrates.
Screen printing has the following features:
1, wide substrates: because the plate is made of silk, which is soft and elastic, so the substrates for flat or curved surface, hard or soft, big or small can be printed.In addition, screen printing because of low pressure can also be printed in fragile substrates.
2, the ink layer thickness and covering power is strong, screen printing ink layer thick, pad printing effect is unattainable.Such as covered with a white background, below using common printing method is needed in the same three to four times, and as long as screen printing can be done at a time.Screen printing ink layer thickness generally 20 microns, special thick film printing up to 100 microns, the thinnest there are 6 microns.
3, strong stereo feeling, because the ink layer thick, so the generic print and copy the effect of the painting is very lifelike, its colour is considerably more than offset printing;But on the fine texture of the printing, the printing effect.
4, good light fastness, a pigment mixed with light and fluorescent pigment in the ink, the print pattern can be permanently maintained and not suffer indignities moderate the influence of the sun, even can glow at night.Therefore, screen printing products suitable for outdoor advertising, signs, etc.DVD, plastic products, toys, stationery, metal, ceramics, wood, glass, solar panels to do high precision printing.
5, large format: in printing area, because general pad printing is not nearly as limited by mechanical equipment and screen printing.Screen printing the maximum width has reach 1 m even more in the future.
