Digital printing refers to the printing of expected patterns and colors on textiles through digital technology. Digital printing is used for printing proofing and small batch production, both convenient and cost saving, which mainly saves the process and cost of plate making and network making. The key practical techniques for proofing and production of digital printing are color, graphics and color fastness. The expression of pattern can be achieved through color separation and design software. Color can be achieved through screen display, color card toning, color measurement, experience toning and other methods.
1. Screen display. To adjust the color of an image by adjusting the color displayed on the screen, usually by selecting or adjusting the color on the screen through the color menu. This method is very useful when matching colors or starting to mix colors. It is a common method used by designers. However, because the hair color principle of fluorescent screen is different from the hair color principle of dyes on fabrics, the colors displayed on the screen cannot be fully expressed by dyes on fabrics, and the subtle differences between the colors displayed by dyes cannot be clearly displayed on the screen. Therefore, this is a general method of color mixing, and cannot be used as an exact color mixing.
2. Color card toning method. Adjust colors by comparing the colors in the color card.
3. Color measurement. With the help of color measuring instrument, the target color block is measured, and the color measurement results are input into the computer, and then the color is printed. This method USES instruments to determine color and thus excludes many human and environmental factors.
4. Empirical toning method. The speed of its toning process, the accuracy of the results completely depends on this need operators in the daily work of continuous analysis, accumulation.
Digital printing technology and traditional printing technology are two completely different printing mechanism, digital printing machine proofing has become the mainstream production mode in the western printing industry. At present, more than 90% of the printing enterprises in Europe have adopted digital printing machine for proofing. These enterprises generally believe that digital printing machine has rapid response, low cost and good consistency of proofing effect. Digital printing machine has become an indispensable tool for the printing industry in Europe.
Heat transfer machine is the general name of the printing machine using heat transfer printing technology, heat transfer printing machine includes plane hot stamping machine, high pressure hot stamping machine, shaking hot stamping machine, cup machine, pan machine, cap machine, drum machine and other heat transfer printing machine. The range that can print is very wide, include planar hot stamping already, also include cup, dish, cap these curved surface hot stamping, heat transfer is a new technology, domestic just just entered right track.
1. Beautiful pictures, with ordinary hot stamping machine, heat transfer machine can be completed.
2. Color pattern once forming, no need to register color.
3. Simple operation, exquisite printing and low production cost.
4. Small loss of products, high added value, strong decorative technology.
5. High covering power and strong adhesion.
6. Meet the green printing standards, no environmental pollution.
Thermal transfer press can be divided according to the type of machine. Heat transfer machine is generally divided into: hot stamping machine, high pressure hot stamping machine, shaking hot stamping machine, baking cup machine, baking pan machine, baking cap machine, drum transfer machine these categories.
1785 began to create the use of printing equipment, the first component of the roller printing machine. Drum printing machine is a kind of thermal transfer printing machinery equipment, according to the diameter of the drum is different from different varieties and prices.
Flat screen printing machine printing plate is a flat screen version, flat screen printing machine with both guide and board. The guide tape flat screen printing machine is called the guide tape printing machine, which is suitable for printing large areas of water pulp in clothing cutting pieces, but not for printing glue pulp.
Flag printing machine first for the advertising industry flag cloth do digital printing, its application field is very wide, flag machine operation is brief, the machine printing cost is low, computer fool operation, is the comparison of commonly used printing equipment!
In the production process of printing, the garment digital printing machine will more or less have some failures, resulting in the damage of printing products, and even the loss of the company. For example, apparel digital printing machine printing will appear horizontal stripes. Horizontal stripes refer to the different colors and shades on the printed product patterns, resulting in the failure of lines. The fault of horizontal stripes can be solved by finding out the “disease” of horizontal stripes.
Ink problem. Use the ink of pass quality as far as possible, use inferior ink to often can appear to print breakdown, the most important is still can damage shower head, a shower head tens of thousands of pieces, broken did not have. It is recommended to use the imported Korean Inktec heat transfer ink.
Step size problem. Refers to the slow delivery of the medium, resulting in each step is covered by the ink. After passing through multiple passes, the stripes appear uniform, and the stripes are darker than elsewhere. At this time, we can set the step size parameters of each machine to adjust through the operation interface or software.
Transportation. The transportation problem is actually the medium transmission system. For example, if the ribbon of the straight jet printing machine is not uniform, the folded ink can not be sprayed on, and eventually horizontal stripes appear.
Of course, the fault that appears horizontal stripe is not only these 3, still have other reason be caused by. Therefore, when doing printing, our garment digital printing machine needs a lot of observation, to stop the fault immediately, to avoid more fault, and then to remove the fault cause and find a solution.
Heat transfer printing is a new printing and dyeing technology which is emerging in the world in recent years. First, use advanced printing techniques to dye special prints (waterborne or oily), print all the necessary patterns on special paper to make transfer printing paper with various patterns, and then on heat transfer printing machine. The transfer printing paper printed on the side of the printed pattern and the printed fabric, through the heat and pressure, using the paper dye sublimation, transfer to the printed fabric, in the printed fabric to form the required patterns. Thermal transfer printing machine is more and more popular nowadays, and its three advantages cannot be separated.
It does not require plate making, printing, repeated color steps, screen printing and heat transfer methods required by various types of tools, materials. Using a printer, you only need to prepare an ordinary computer. One operator can operate the printing operation completely independently, save manpower and material resources, and the way is simple, instant desirable. The experience requirement to operator is low, want to know simple picture processing software to be ok only.
It can be printed not only on tough crystal, stone, metal, glass and other materials, but also on soft leather, cloth, cotton and other materials. It can be printed on inorganic materials, or on organic materials with complex composition and variety. With more and better compatibility for materials, the use of the vertix printer avoids the problems of screen printing, water transfer material selection, as well as the damage of heat transfer to other organic materials such as leather, cloth and cotton. It caters to diversified market demands and can provide more comprehensive production services for users.
Printer is no longer the traditional printing mode and method, is no longer a simple manual operation of the past and printing craft, with high technical content of computer generated, and the combination of automatic control technology for the better, can be very precise on the printing area and position, to avoid the manual printing house in the position of the deviation problem. As it is a one-off multicolor printing, there will be no matching problem. These advantages can also be combined with engraving and etching in a very effective way, such as printing beautiful images in the engraving area, or precise etching after printing, making good breakthroughs in the engraving industry.
