What are the color mixing methods of digital printing machine?

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.

The following mainly introduces four kinds of digital printing machine toning method, for your reference.

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.

How to solve the transfer printing problem of natural fibers?

Because transfer printing has many advantages and the products produced are also of great commercial value, it has developed rapidly since it was put into production in the 1960s. However, because it is only suitable for synthetic fibers with clear glass transition temperature, its development is hindered and can not be applied to natural fibers. How to solve the transfer printing problem of natural fibers has become a hot research topic at home and abroad.

So far, the main solutions are as follows:

1) Grafting denaturation, such as acetylation, benzoylation, etc. This allows the fibers to accept disperse dyes.

2) Surface polymerization. This method is to polymerize macromolecule materials on the surface of fabrics, so as to accept disperse dyes like synthetic fibers, such as polyester method, styrene method and so on.

3) Fiber expansion. Expansion phenomena in amorphous region of heated polyester fibers were simulated and disperse dye gas was admitted. However, the fastness is insufficient due to the lack of fixation with fibers. So this method can only be used in conjunction with other methods of fixing dyes. Polyethylene glycol (200 molecular weight) is generally used for fiber extrusion. It is not only an extruder for cotton fibers, but also a solvent for disperse dyes.

The common feature of the above methods is that natural fibre fabrics must be pretreated before transfer printing, which increases the production process and cost. More importantly, in order to clean the remaining non-functional materials on fabrics, it is necessary to wash and dry them. In this way, it is impossible to eliminate wastewater discharge and increase the consumption of heating energy, which makes it difficult to get rid of the heavy burden of traditional printing and dyeing production.

This natural fiber transfer printing method does not retain the characteristics of synthetic fiber transfer printing method, and is difficult to be accepted by manufacturers. Some methods still leave harmful substances such as formaldehyde on fabrics, which do not meet the requirements of environmental protection. In addition, after printing, many fabrics migrate over time, resulting in blurred patterns. Therefore, although this method has been applied, it is not ideal. Others use spraying pretreatment liquid on the part of natural fiber clothing and printing after drying.

What is the main reason for the failure of each part of rotary printing machine?

Today to detail the main reasons for the failure of various parts of the rotary printing machine.

The open ground (bottom). The pattern on the printed fabric is partially exposed to the ground color. Causes: low wool efficiency, thick size, too fast speed, low pressure, too shallow overshading. If the shaft core is bent, it will cause color difference between left, middle and right.

Knife blade. Forming a single or multiple colored line on the surface of the fabric. The main reason is that the scraper has a small gap (the blade has not been polished for a long time, the surface of the cylinder is rough, etc.) or some impurities (fluff, undissolved substance in the color paste, etc.), which leads to the color paste on the cylinder not being scraped clean.

Jump cut. The horizontal band left on the fabric by the shimmer of the cylinder which is not scraped by the flashing of the blade. The main reason may be that the blade is installed too low, causing the blade to flash or the hammer pressure is insufficient, of course, the sleeve is installed improperly and the gear bite is tightened can also cause the jump knife.

Dragging. Drag a small part of the same or different color of the non-pattern under the pattern. The reason may be that 1. The blade is installed too high 2. The fabric cannot be absorbed in an instant due to the thick color paste, and 3 sleeves are not arranged reasonably in the pattern. Generally can use to adjust knife Angle, color paste thickness and add knife to solve.

Splash. A splash of color from the blade landed on the fabric. If the scraper is installed too low, the speed is too fast, the slurry is too thin, and the cylinder is horizontal, this defect is easy to occur. If the problem cannot be solved through adjustment, a piece of cloth can be put on the top of the cylinder to keep out. In addition, if there is a sand hole on the cylinder, the resulting color points are made in a regular circle, different from spatter.

What kind of fabric material is suitable for digital printing?

In digital printing, the large number of printhead ensures high quality pattern design and fast production speed. However, some fabrics are not available for digital printing because the shower head is too close to the fabric. For example, there are some out-of-wire fabrics that come in contact with the sprinkler and cause damage.

Textile digital printing technology can be used for woven and knitted fabrics. Below, I detail which materials are suitable for digital printing.

cotton

Cotton is a natural fiber, especially in the fashion industry, which is widely used in clothing for its high moisture resistance, comfort and durability. Using the textile digital printing machine, you can print on the cotton cloth. In order to achieve as high quality as possible, most digital printing machines use reactive ink because this type of ink provides the highest washing fastness for printing on cotton cloth.

viscose

Another natural fiber widely used in the fashion industry is viscose. It is feasible to print on adhesive with digital printing machine. Like printing on cotton, printing on viscose with reactive ink can achieve the best effect.

wool

It is feasible to print on wool fabric using digital printing machine, but it depends on the type of wool fabric used. If you want to print on “hairy” wool, that means there is a lot of fluff on the surface, so the sprinkler head must be as far away from the fabric as possible. The diameter of the wool yarn is five times that of the nozzle in the nozzle, so it will seriously damage the nozzle.

silk

Another natural fiber for textile digital printing is silk. Silk can be printed with reactive ink (better colour fastness) or acidic ink (wider colour range).

Polyamide lycra

Polyamide lycra is a fabric mainly used in swimwear. Can use digital printing machine on polyamide lycra printing, preferably using acid ink. Using acidic ink, you can get the highest color brightness, the best washing fastness and salt water resistance, chlorine-resistant bleaching fastness.

polyester

Polyester has become an increasingly popular fabric in fashion over the past few years. However, the disperse ink most commonly used in polyester printing works well for high-speed digital printing machines.

Blended fabric

Blended fabric refers to two different types of fabric, which is a challenge for digital printing machines. In textile digital printing, a device can only use one type of ink. Since each material requires a different type of ink, as a printing company, you must use ink suitable for the main material of the fabric. This also means that the ink will not be colored on another material, resulting in a lighter, white color.

Generally, textile digital printing machine can deal with 70-30% proportion of blended fabrics. For example, 70 per cent cotton and 30 per cent polyester blends can be printed with reactive ink. However, for 60 to 40 percent of blended fabrics, the use of digital printing will have limitations in terms of color depth.

What is the coating characteristic of the thermal transfer printing machine?

In the international market, thermal transfer printing technology has always been one of the high-end technologies in the printing industry and occupies a very important position in the high-end printing market. With the annual growth of China’s GDP and the improvement of people’s income and living standards, people have more and more demands for personalized printing technology talents. Turning high-end technology into small investment projects will give our investors a new direction of investment — a personalized “gold mine” market with a potential market of 100 million yuan.

What is the coating characteristic of the thermal transfer printing machine?

Personalization. Has the unique decoration effect. Applicable to any material, compatibility and its wide range.

Meet special needs. Digital cameras can take any photo and download any clear patterns can be produced to meet the different needs of consumers.

The pattern is clear. The picture is fine, realistic, colorful, and the picture is soft and layered.

Pictures can be big or small. As small as a printer can print any tiny graphics and text, as large as a printer can print any spliced pattern.

Environmental protection and durability. The paint is heated and sublimated to permeate the interior of the wall, then solidified, so the pattern is durable and environmentally friendly.

Widely used. The design can be made on any flat plate or flat plate bending products with high temperature resistance above 190 degrees. It is widely used in work and home decoration.

Simple construction, not affected by the season. Regardless of spring, summer, autumn and winter, thermal transfer paint can be applied 365 days a year. Construction does not require professional technical personnel, that is, learning.

Low cost. Traditionally, a painter painted a 2-meter by 5-meter mural, because of time and labor, high price, often tens of thousands, hundreds of thousands, resulting in consumer demand. Objectively, it limited the popularity of the murals industry. And heat transfer printing coating, as a result of simple, efficient, time – saving, labor, so low cost.

So heat transfer process applied to a variety of product surfaces. We can design and produce heat transfer film according to customer’s requirement. Heat transfer printing process is widely used in plastics, cosmetics, toys, electrical appliances, building materials, gifts, food packaging, stationery and other industries.

In the future, the manufacturer of thermal transfer printing machine equipment will be a severe challenge, which will not only face the personalized choice of customers, but also the quality of market printing products. Printing machine maintenance, achieve steady improvement.

What causes horizontal stripes to appear when the garment digital printing machine prints?

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.

There are several kinds of fault of horizontal stripes: transportation problem, ink problem, step problem and so on.

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.
