With the diversification of cup styles, more and more people also began to pursue personalized cups, Before, we have also analyzed that Different types of cups have their Pros and Cons. and it is precisely because of the various printing needs, cup manufacturers also launched a variety of different printing processes. cup manufacturers will choose a more appropriate printing process according to the needs of customers. Today, let us take a closer look at several printing processes that cup manufacturers must know.

Silk Screen Printing

The most normal and simple print is for silk screen printing. It refers to the use of the screen as a plate base, and through photographic plate making method, made with the graphic screen printing plate. Screen printing consists of five elements: screen plate, scraper, ink, printing table, and substrate. Use screen printing plate text part of the mesh through ink, the nontext part of the mesh can not be printed through the basic principle of ink. Printing in the screen printing plate into one end of the ink, with the scraper screen printing plate on the ink part of a certain pressure, at the same time toward the screen printing plate at a uniform speed, ink in the movement of the scraper from the mesh of the text part of the extrusion onto the substrate.

The advantage of this printing process is that simple and cheap, both can be used for plastic, stainless steel, glass materials. The disadvantage is that the fastness is poor compared to other prints, and it can be easily scratched off by sharp objects. In addition, its printing limitations are relatively large, only suitable for printing no more than three three-color prints, and there can be no overlap between each color.

Although screen printing is not as advanced as other printing methods, it has a long history and exquisite craftsmanship, and because of its higher profit margins, most cup manufacturers use this printing method.

Heat Transfer

Second I would like to introduce heat transfer, this technology way of printing and transfer printing film processing divides into two parts, printing film using network printing resolution (300 dpi), will design printed on the thin-film surface in advance, printing the design level of rich, colorful, go, small chromatism, good reproducibility, can meet the requirements of design patterns is an effect, and is suitable for mass production. So most cup manufacturers will choose this method to mass-produce cups.

Transfer printing process through a heat transfer machine processing (heating pressure) transfer film on the exquisite pattern transfer on the surface of the product, forming ink layer and product surface dissolved into one, realistic and beautiful, greatly improve the grade of the product. But because of the high technical content of the process, many materials have to be imported.

Heat transfer printing is suitable for printing with more colors and more complex compositions. He needs plate making before production, so the cup manufacturers will charge an extra plate fee, so the price of thermal transfer printing will be higher than ordinary screen printing. But whether in color or printing fastness, heat transfer printing can make buyers very satisfied.

Electroplate

Is using the principle of electrolytic plating on some metal surface on a thin layer of other metal or alloy plating process, is the use of electrolytic action made of metal or other materials adhered on the surface of the parts of a layer of metal film technique to prevent metal oxidation (rust), improve the wear resistance and electric conductivity, reflective resistance, corrosion resistance, copper sulfate, etc.) and create beautifully, etc. Many coins are also electroplated.

Electroplating is only suitable for stainless steel materials, it will let the surface of the glass become shiny. Moreover, there is no color limitation in electroplating. Customers can customize the electroplating color according to their preferences, and they can choose a solid color or gradient color.

Many cup manufacturers will choose this way to help customers do some OEM personalized customization.

Ceramic Decal

Ceramic decal is one of the most widely used decorative techniques in modern ceramics. Sub-glaze decals and underglaze decals, etc. Glaze decals have film decals, water decals, and glue decals. Underglaze decals are printed on decal paper only pattern outline line, and then artificial color after printing; Also have one-time affix line color, say to take water decal. Decal paper has paper and plastic film two kinds, with the paper must go through uncovering paper, washing and other processes, after the development of film paper, it does not need to uncovering paper and other processes and facilitate mechanization, continuous operation.

Application scope and characteristics of silk screen ceramic decal paper:

1) Ceramic decal paper is mainly used for the decoration of patterns and colors of ceramic vessels, replacing the hand-painted and color spraying process used in the past.

2) Screen printing ceramic decal paper resolution up to 40-50 lines /CM.

3) After the silk screen printing ink pattern on the ceramic decal paper is pasted on the ceramic vessels, it needs to be fired at 700-800℃ or 1100-1350℃ to attach firmly, and the color depends on the variety of color agent in the ceramic.

4) Ceramic decal paper is the carrier of ceramic ink, which is divided into ceramic glaze pasted paper and ceramic underglaze decal paper. The types of decal paper are different because of their composition.

5) Because of the strong covering power and poor transparency of ceramic ink, it is not possible to use the principle of three primary colors for printing at present, and the dot printing method is non-overprint side by side special color ink dot printing.

6) Glaze paste printing ink for high-temperature solvent ink;

Underglaze decal printing ink for high-temperature water-based ink.

The most common printing method of cups in the production of cups by cup manufacturers is as above. If you have more questions, you can click the consultation next to it, and we will answer you at any time.
