How to implement digital transfer technology for decorative printing

After Shanghai Printing Co. understands the digital transfer method, it should consider where to apply them. If you are using a system based on traditional surface printing agents (conventional inks, toners, wax tapes, etc.), Shanghai printing is mainly limited to the transfer process of light-colored garments, in addition to adhesive printing with the aid of polyester. Cloth transfer paper can be completed. However, choosing a digital printing company for transfer printing is enough to satisfy the order of receiving a single piece of clothing using a conventional printing device or a short version of a printing company's clothing order, and this brings a lot of order advertising printing.

The use of sublimation and printing in Shanghai is a way to expand the range of substrates. Printers Condé and Xpres can provide complete thermal sublimation printing transfer printing solutions in Shanghai, including digital presses, software, inks, printing presses, heat transfer machines and a wide variety of sublimation images for digital printing. Transferred polyester or polyester coated products. Screen printing These products cover mouse pads, dials, decorative sheets, printing labels (inscription) cards, key pendants, photo frames, business cards printed glass or ceramic cups, coasters and more. The disc printing mug is one of the popular packaging and printing products for thermal sublimation transfer imaging products.

Manufacturers do not necessarily need to purchase pre-coated materials for textile printing. Some products, such as Condé's Liquid Stone color printing coating solution, allow the coating of non-porous materials to adapt its Shanghai business card printing to the dye-sublimation transfer process. The coating is based on water-based Shanghai packaging designed liquid polyester, using oil brush, roller or sponge.
In textile non-carbon copy paper products, chemical fiber T-shirts, sportswear, pillowcases, towels and similar scratch cards do not require special coating for sublimation transfer. However, the purified fiber clothing is not very comfortable to print when enveloped. Relatively speaking, customers prefer cotton digital printing or blended garments.

In the early days of digital transfer in the dye-sublimation poster design, the only way to print cotton products using the thermal sublimation imaging method was to print the dye-sublimation ink on polyester-coated transfer paper. Shanghai Advertising Design Co., Ltd Paper is printed and the flag is then designed to transfer the image with the coating to the garment. The only sample design difference between thermal sublimation and traditional imaging methods relying on transfer paper coating for transfer is that, during the thermal transfer process, the dye-sublimation ink is absorbed by the disc onto the coating, not the coating and clothing. Between surface printing plants. Despite the differences, the two transfer results give people a feeling of dull printing and similar decals.

This has led garment factories to work on glass printing to develop a thermal sublimation transfer method that does not require a transfer paper coating to make cotton garments more comfortable. Three years ago, Hanes' corporate flyer designed to introduce soft L-shaped ink apparel. It is a series of T-shirts and other apparel products made with patented technology and double-sided materials. The interior of the fabric fiber envelope printing is soft cotton, and the exterior is coated with a thin layer of 100% polyester layer of Shanghai printing factory, which is suitable for dye-sublimation transfer printing, and it no longer needs special coating for Shanghai adhesive printing. .

Cost problem

Digital Transfer Technical Instruction The investment in printing differs depending on the printer and ink system purchased. The complete desktop system purchased for digital transfer begins with all equipment, inks, transfer papers, and substrates of the card manufacturer. The investment is approximately between $4,000 and $8,000. It is important to have a very strong packaging design. The poster design of high-end output devices should be selected instead of home or office equipment. The purchase of printing equipment alone requires approximately $2,000 to $6,000. If you choose a large-format business card design system, the investment in the printer is at least five times that of a digital printing desktop system based on the same technology.

The cost of consumables depends on the type of printer used in carbonless copy paper, the format, and the type of ink system used. The most direct way to estimate the cost of consumables leaflet design is to accumulate the basic cost of each item. Taking a T-shirt as an example, its consumables scratch card includes ink, transfer paper, and printing clothing. Calculated at the current market price, the material fee for printing each garment is approximately 3 to 5 dollars for advertising design, and the market price for finished products is 15 to 20 US dollars, from which manufacturers can obtain 50% to 75% of profits.

Profits from the digital printing screen printing plant The new profitable point of printing on the CD-ROM is not limited to high-value introduction of new technologies for screen printing or expansion of customer groups. Short prints and special printing needs of customers are potential opportunities for sticker printing. With the introduction of digital transfer technology, manufacturers can desktop desktop calendar can do a lot of work can not be completed in the past, to get more product brochure business opportunities.
About screen printing

Plastic products have entered the commercial market long ago. At present, the decoration of plastic products mainly adopts screen printing, and the cooperation between screen printing and plastic decoration industry has made continuous progress. As plastic processing plants continue to develop new material formulations, screen printing has been able to print on plastics with different surface textures, different hardness, and different materials. So far, screen printing has surpassed other alternative processes for plastic decoration such as flexographic printing, offset printing, pad printing, and digital printing. However, with the continuous progress of these printing processes, the plastics processing industry naturally raises the question whether screen printing can continue to occupy the dominant position in the field of plastic decoration. Of course, we expect that the demand for the plastic decoration market will continue to expand with the emergence of new plastic products. The rich and colorful handicrafts, the continuous development of industry is a good example of the main role of screen printing in the plastic decoration market. Screen printing can be regarded as a kind of universal printing, it can use a variety of inks to print on a variety of different substrates, it is this flexibility and versatility that will facilitate it in many different printing processes Take advantage of. And the most important is that it has high productivity, predictability, and consistency in printing. This article will discuss screen printing equipment, inks, screens, and process features, and look forward to some new advances in this area in order to further improve the screen printing quality. Ink does not have a printing process that can use as much ink and coating as screen printing. Other printing processes are often limited to print on plain paper, cardboard, and plastic, and the ink layer is relatively thin. The screen printing ink layer thickness can be flexibly grasped according to need, thin or thick; substrates include almost all kinds of materials: wood, textiles, metals, glass, ceramics and so on. At present, there are many types of screen printing inks, such as fluorescent inks, fragrance inks, color-changing inks, reflection inks, foaming inks, and discharge inks. Different substrates require different formulations of ink and can be selected from matt, semi-gloss, high gloss, and clear inks. In addition to printing on flat plastic materials, screen printing can also be directly printed on containers, bottles and other cylindrical objects. In addition, screen printing inks have excellent fade resistance, weather resistance and wear resistance. Rubbing.

In order to meet the environmental requirements of inks, screen-printing ink manufacturers have also invested a lot of money in research to develop many environmentally-friendly products such as UV inks, water-based UV inks, and water-based inks. At the same time, instrumental plastics that meet health standards have also been developed. Box decorative ink. Wire mesh plays a decisive role in the quality of the image or ink layer. Screen is the central link of the entire screen printing technology. At present, there are various types of screens on the market, such as metal screens and synthetic fiber screens, which are suitable for printing different products. But what is important is that screen printers or plastic decorators must have a good understanding of the variety of screens and screens for each type of print. Grasping the knowledge of the screen can avoid unnecessary interference in the printing, and can ensure the economic use of ink. The correct choice of screen has a great influence on the final printing effect. The following points should be noted when selecting the screen.

The larger the opening of the screen, the greater the ink flow through, and the thickness, flatness, ink drying, ink consumption, and hiding power of the ink layer are largely determined by the screen. The screen must be selected according to the substrate used (paper, cardboard, plastic, and the smoothness or roughness of the surface, etc.). High-precision prints require the use of screens with excellent stability, such as wire mesh or polyester mesh. The right choice of screen to use directly affects the cost of the product. Compared with other printing processes, the screen printing ink layer is relatively thick, and it can also flexibly control the ink layer thickness according to the requirements of the substrate.

For example, most images are printed with a dry ink film thickness of 5-7 UM, and can be increased to 100 UM when needed. This is very important in electronic printing such as circuit boards and film openings. It is clear why people often say that screen printing not only represents the printing process but also coating technology. At present, the application of screen printing technology is becoming more and more extensive. At the same time, the doors of many new industrial fields are open at all times, creating more opportunities for screen printing. Printing format; Printing size can range from a few centimeters to several meters. In super-large-format advertising printing, the substrate can be not only vinyl paper but also hard plastic. Special effects and shapes Screen printing is economical for both long-lived and short-lived jobs, while offset printing and flexo printing are only cost-effective for medium-to-long live printing. Digital printing is only short. It is only worthwhile for the live version and the Chinese version to be printed. Compared with screen printing, there is a great deal of flexibility. Durability. Tests of chemical resistance and weather resistance have shown that screen printing inks have a longer life than other printing inks. This is very important for the printing of traffic signs, sports equipment (skids, etc.) because these prints are To withstand the challenges of harsh weather conditions.

The following will introduce some of the latest advances in screen printing technology. Screen printing has now entered a higher stage of control, becoming a predictable, repeatable process. Meet Predictability Requirements In the prepress and printing process, the focus is mainly on how to increase efficiency and achieve consistent printing results. In order to be able to operate successfully under a variety of conditions, the key is to develop a reasonable work routine, simple steps, and testing of intermediate results. Only in this way, those semi-skilled operators can fully understand every working procedure and remedy mistakes in a timely and systematic manner. Simplify the prepress program Most screen printers use flat printing methods. To improve the quality of printing, the work procedures must be simplified, and equipment and materials must be improved. At the same time, the screen tension, screen mesh number, etc. must be systematically Testing. The positioning system positioning system is very important in the prepress program, which can ensure the accurate positioning of the image on the screen. The positioning mark can be directly marked on the printing plate or the film, or it can be automatically used on the printing machine by using the prepositioning system. The screen is accurately positioned to ensure greater accuracy and can be replaced in a very short time. The screen mesh is the core carrier of the printing plate. The prepared plate will pass the ink under the pressure of the squeegee. The mesh is transferred to the substrate. During operation, it is very important that the screen maintain a high and stable tension. A new generation of high-strength polyester screens can meet this quality requirement, higher screen tensions than in the past, longer retention times, more precise printing, and higher print rates. Photosensitive resin plate. For super large-format printing, resin plates with high photosensitivity have been developed, and these advances are beneficial to the production of standard stencil emulsions. The coated plate can be stored for a longer period of time. The pre-coated screen version (PCF) has also been developed and can be used for circuit board printing and CD/DVD printing, which can reduce a large number of manual operations, improve printing quality, and reduce production costs. Pre-coated screens can be automatically stretched and glued and quickly exposed. Excellent printing performance Most screen printing can be combined with high-speed production lines, and its production speed is limited by many factors, including the drying box's traffic, the substrate's automatic feed speed and so on. usually
