How are pad printing, screen printing and transfer printing distinguished?

the principle of pad printing is that the pattern to be printed is first made into a gravure by using a photographic plate-making method, and then transferred to the printed object through a special silicon offset printing head, and special ink can be prepared according to the different materials of the products to ensure the quality. The process of pad printing machine is divided into the following four points: 1. The ink is evenly covered on the steel plate by the brush. 2. Scrape the excess ink with an ink scraper. 3. The printing head descends to the steel plate to pick up the ink in the pattern. 4. The printing head shifts and descends until the product covers the pattern. The pad printing machine is suitable for industries such as plastics, toys, glass, metal, electronics, sporting goods, stationery, optics, IC packaging, etc. Scope of application of pad printing machine: printing ruler, pen, ball, doll's eyes, watches, cameras, housings of hair dryers, ceramics, medical instruments, rackets, audio tapes, electronic parts, IC, CPU, DRAM, computer housings, keys, decorative signs, mobile phone housings, etc.

The so-called screen printing is to carve a screen printing plate and then print it. It's very simple. PE EMBOSS means to carve a copper mold first, and if the pattern is one color, pour the rubber material in and then come out. If it is multi-color, it's a little troublesome.

There are four types of printing: plane printing, convex printing, concave printing and screen printing.

Among these four types, printed paper is the most common one for plane printing;

to put it simply, convex printing and concave printing are both used;

and screen printing contains the most extensive and can print most of the substrates of the first three, and it is also the most common. Although you don't know much about it, look around, such as letters on the keyboard, words on the display, patterns on T-shirts, pictures and texts on containers, etc., all printed by screen printing.

screen printing is actually screen printing. Simple screen printing is to stretch a screen (very honey) on a frame, then apply photosensitive glue, then laser output the pictures and texts to be printed with sulfuric acid paper, put them under the screen and print them with an exposure lamp (for a few minutes), and finally use blisters, so that the parts that need to be printed will have no photosensitive glue, while other parts that don't need to be printed still have photosensitive glue, that is, This method is hand-printed. If you master it, print some simple things, such as umbrellas, T-shirts, printed calendars, cylindrical containers, flat metal, etc. If you don't have silk screen printing there, you can develop the market. The cost of a screen printing plate is only a few dollars (because it can be reused), while the printing price can be determined according to the market. Generally, printing a thing is several cents or several dollars, depending on the price of the substrate.

what is thermal transfer printing? It is a special printing method that prints any photos such as portraits and landscapes on color inkjet paper with thermal transfer ink, and then heats them to a certain temperature within a few minutes by thermal transfer equipment, so as to transfer the color of the images on the paper to materials such as porcelain cups, porcelain plates, glass, metals, plastics and clothes realistically. Its main feature is that the transferred image is bright in color and rich in layers, which will not fall off, crack and fade, and is suitable for small batch production. It can be used in personalized product making, prepress printing, advertising sign production, clothing hot stamping and other related industries.
