Digital printing process
Entering May immediately, summer is coming soon. All kinds of sweaters and T-shirts are about to fill our vision. How did these stamps come from? In addition to being curious by outsiders, people who may just be entering the digital printing industry will also be curious. Indeed, the process and operation of digital printing machines are often one of the most worrying issues for users. Then let's take a look at the digital printing process.
The technology of printing sweaters and T-shirts by digital printing machines is actually very simple. It is mainly divided into four steps: picture processing, pre-spraying treatment liquid, direct textile printing, and color fixing. However, these four steps seem to be simple, but there are still some tricks. If you can't grasp the essentials, either the printed results are not satisfactory, or it is easy to wash off the color.
1. Picture processing
If you want to print a better effect, the picture must be good. The impurities in the picture must be cleaned. The color blocks that are easy to produce color differences should be fine-tuned in the picture processing software (you can find a professional to operate) to ensure the picture quality. This can also make the basic preparation for printing effect that you want.
2. Pre-spraying treatment liquid
Before the clothes made of pure cotton are fixed to the printing machine platform, they need to be pre-treated. The pre-treatment liquid for light-colored cotton fabrics and the pre-treatment liquid for dark cotton fabrics are different. The pre-treatment liquid of light-colored fabric is mainly used to increase the vividness of the pattern; the pre-treatment liquid of dark-colored cotton fabric is used to chemically react with the white ink used for priming, so that the white ink can be firmly absorbed in the dark pure on cotton cloth. The processing tools are diversified, you can use professional spray coating equipment, you can also use electric spray cans. In the process of spraying the processing liquid, it must be sprayed evenly to ensure that the processing liquid is sufficient. The uneven or insufficient amount of printing will not be good, and it is easy to wash off, and excessive spraying is easy to cause waste. Some brands of pre-processing liquid are expensive, and if they cause waste, the cost of spraying a garment may sometimes exceed that of white ink.
3.Direct textile printing
The printing process is relatively much simpler. During the operation of the printing machine, ensure the stability of it and do not touch the data cable and power cable at will. Choosing a suitable printing machine can help you reach the designated position in one step.
Fedar digital printing machine is easy to operate and intelligently designed. It not only has excellent printing effect, but also is simple to use. Fedar’s new product FD6198E-3200 this year has been upgraded in technology and more humanized in design. The EPS3200 printhead (Epson 4720 printhead) is printed more finely and has better printing effect.
The product from the digital printing machine is actually only a semi-finished product. Only after fixing the color can the pattern not fall off. Fixing color also has certain tricks, too high temperature is easy to cause damage to the cloth, too low temperature, color fastness is not enough, too long time is easy to cause damage to the cloth, too short time, pattern will be washed away. Therefore, it is necessary to accurately grasp the fixing time and temperature in order to achieve the best printing effect.
