Screen printing number tips

In the daily life, there will be many businesses that print numbers. In view of the special nature of screen printing, it is not possible to use numbers to code numbers, and it is only possible to adopt various simple methods to suit local conditions.

For example: screen printing key card, which uses 1mm transparent plexiglass, flash silver spray paint on the back, back engraving with a mechanical engraving machine, then spray paint method, double-sided production, with two sides in the middle glue, due to large quantities, small writing , Three sets of colors, plus small numbers, if you insist on the use of engraving machine production is undoubtedly time-consuming, and the defective goods, the use of screen printing method can solve most of the problems, can be easily printed on the number of problems, one is not possible for each number For one edition, the second is the problem of aligning the numbers. Although it is unsuitable to control the number of the engraving machine during the cutting process, it is also very troublesome to register and then engrave after printing. At this time, the transparency of the organic glass can be used. Perspective alignment printing.

First make a small number version, typesetting: 0000,0010,0020,0030,0040,0050,0060,0070,0080,0090 as a group, and then as 0,1,2,3,4,5,6,7, 8, 9 is a group, (the number of groups of five or six is ​​increased by the first group of 0, the vertical group of 0-9 can be), such a small version can spell tens of thousands of groups of numbers, with the manuscript or after printing On the platen, draw the upper and lower numbers of the baseline so as not to be skewed. When printing, set them in groups of 10, separate the codes, and print them in the order of numbers. The first 000 (end O is sealed with glue), 9 pieces, and the bottom is translated Ink 000, one, the same way will be large number (the first set of printed), and then overprint small numbers (mantissa), the advantage of doing so is that the serial number printing will not be confused, and will not appear dry version phenomenon, for Opaque objects are not suitable for this method. They can only be used as positioning marks according to the shape of the object, or they can be overlaid with transparencies, or they can be fixed on movable slide bars or chutes to align with printing plates. The position of the object, pinned and positioned, one card per group number, so that one (group) number is moved and one bit is locked.

The above is the method of printing the number of positive pictures. For the number of the negative figures left behind, such as the house number, the above is the number below the street name, or the content of the batch medals requires the same content, the number is exposed at the bottom and some lines are to be used as outlines, and the numbers are overprinted. , it is more difficult, because the printing must be the same color, can not have a border, do not impress the number of imprints is not practical, screen printing ink is not as thin offset printing ink, offset printing can be used, its number is not obvious at the edge of thin ink coincidence, Whether it is a translucent ink screen printing effect can not be compared, then can be used to peel off the ink or easier to remove the ink with tape, use the Zhengyang map number matching method to print the number, but it must be accurate positioning, after drying With negative graphic version (number position all exposed) can be scraped, pay attention to squeegee should not be too fast, the ink should not be too sticky, the screen should be thick, so as to print a good finished product, thoroughly dried with tape Stick the ink layer at the number to reveal the empty bottom.

For the number on the clothing, due to a large number of apparel fabrics, tooling, sportswear, T-shirts, etc. are mostly printed numbers for garments. Generally, multiple water pastes and overprinting white pastes are printed, but it is not known that the water paste fixes chemical fibers. Poor capacity, and most screen printing individual households can not be specifically formulated to meet the requirements of the water slurry, and drying after drying fixed color printing, and the use of low-cost printing of dark fabric printing white pulp, its light color after drying, coating The knot is hard to handle, and it is not resistant to washing. Although the effect of using white glue or nylon white paste is good, it is still airtight, and the effect is so good that it is overprinted twice. Therefore, some clothing that requires high heat transfer number is selected, and the effect is good. Convenient and quick, but the high price and poor washing resistance is also a problem. Only the sublimation transfer printing or dark-colored fabrics are adopted to avoid baking and discharging, and sublimation transfer paper for thermal transfer banners can also be used.
