What is inkjet printing and what are the applications?

Inkjet printing technology is a kind of digital printing technology, the principle of which is to use the computer to control the nozzle to carry out precise inkjet on the fabric, through different color combinations, spray beam printing sequences and different color mixing methods to achieve the dyeing of the fabric hand color, so as to achieve the effect of printing.

Specifically, inkjet printing machines spray ink onto textiles through a printhead, and the ink color and pattern are controlled by a computer. The number of printheads in inkjet printing machines is usually hundreds, and the ink is sprayed with high precision and speed, which can print very complex patterns and colors.

The advantage of inkjet printing technology is that it can achieve short printing cycles, low-cost potatoes, high precision, multi-variety and small batch production, and can also print complex colors and patterns, which is very suitable for personalized and customized production. In addition, inkjet printing is also environmentally friendly, non-toxic, harmless and other characteristics, and has no pollution to the environment and human health.

Inkjet printing is a common digital printing technology that uses inkjet heads to spray colored ink onto various substrates such as clothes, paper, and plastic films to form printed content such as images and text. Inkjet printing technology has been widely used in various printing industries, including clothing printing, advertising, Mingchang home decoration, electronic product printing and other fields.

The principle of inkjet printing technology is very simple, mainly including the following steps:

Digital image processing hall: First, the image that needs to be printed is acquired and processed using equipment such as a computer or digital camera, usually including image, color correction, resolution adjustment, and other operations to obtain the final printed document.

Ink jetting: The prepared ink is loaded into the inkjet head, and the ink is sprayed out by pressure, the inkjet head usually has many small holes, each small hole corresponds to a tiny electronic device, which can be quickly switched on and off to control the direction and amount of ink jet.

Inkjet control: During the inkjet process, the computer will send instructions to the inkjet head to control the switching time, inkjet volume and other parameters of each inkjet head, so as to get the desired image effect.

Ink curing: The ejected ink is sprayed directly on the substrate and usually takes a certain amount of time to dry and cure to guarantee image quality and durability.

It should be noted that the inks, printheads, control systems, etc. used by different types of inkjet printing equipment are different, but their basic printing principles are similar.

In general, inkjet printing technology has the advantages of low cost, high production efficiency, wide range of application, and good printing effect, and has gradually become one of the important technologies in the digital printing industry.

Hello, the paste is used for printing, and the ink is used for printing, and the substances that carry dyes or pigments are different. The usual carrier of the slurry is water-based, and the usual carrier of the ink is oil-based. Because the substrate is different, the printing is usually on textiles, and the printing is usually on paper, so the flow and fixation requirements of the paste or ink are different.

This is mine, thank you and have a great day.

Inkjet ink, like chemical products such as paint, contain toxic ingredients such as benzene and methanol, and once such chemical raw materials are absorbed by the human body, it is difficult to excrete them from the body. Therefore, the work of dealing with this kind of products is also a special work, and the most important thing to pay attention to in this kind of working environment is good ventilation performance and perfect protection measures. Working in such an environment all year round, if there is no perfect protective measures and a firm sense of protection, there will be big problems.

In addition to the difference in production cost, whether the manufacturer has a rigorous inspection of the ink and whether the testing equipment is perfect, will also affect the quality of the ink.

Generally, large European manufacturers can provide a "Material Safety Data Sheet MSDS", which in addition to analyzing the composition of the ink, will also display the safety standards, including a "risk phrase" crisis index, which will indicate the degree of impact of the ink on the human body and the matters to be paid attention to, but if it is found that there is 2-ethoxyethyl acetate in the MSDS, its "risk phrase" It's R60-61, which shows that it's very toxic.

R60 - long-term inhalation in pregnant women can cause miscarriage; R61 – Affects male reproductive function. This information is important to the user as it tells you whether the ink you choose will affect your health and safety. Before choosing an ink, it's important to understand their composition before making the right choice.

The basic ways of printing are:

1. Direct printing.

The method of printing various colors of floral patterns directly on the fabric is direct printing, and this printing process is the simplest and most common one of several printing methods.

Second, discharge printing.

On the dyed fabric, a slurry containing a reducing agent or oxidizing agent is printed to destroy the ground color and partially expose the white ground or colored pattern.

3. Anti-beam printing.

The printing process of printing the ground color paste to prevent the ground dye from dyeing or developing color on the fabric first, and then dyeing to obtain the color ground flower cloth.

Fourth, paint printing.

Paint printing is direct printing with paint, a process often called dry printing.

The fabric itself has a certain impact on the effect of inkjet printing, and it is necessary to get the ideal spray.

For the ink printing effect, the fabric must meet the following requirements:

The surface of the fabric must be smooth and clean, and it is best to be singeed.

The fabric must have good hydrophilicity.

Inkjet printing should be bleached and desized, but not soft.

The whiteness of the fabric should be good.

The texture and organizational structure of the fabric should be adapted to the printed **. The code is also defeated.

The case is printed on fabrics with different yarn thicknesses, densities and textures, and the printing effect is done.

There is a big difference.

There are many kinds of digital inkjet printing machines.

Fast starting, no limit to color, no limit to pattern, no limit to quantity.
