Digital printing technology is a cutting-edge technology in the textile industry that integrates computer data processing, control, precision machinery and fine chemicals. Digital printing has the advantages of no need to make pattern (net), no color paste, rich colors, good layers, small batch production, fast delivery, water saving, less pollution, low labor intensity, etc., and caters to the contemporary people’s clothing consumption Pursuing the new market characteristics of individuation and greening, so more and more companies are paying attention to it. There are also more and more manufacturers of digital printing equipment. Equipment suitable for various textiles has appeared one after another. The required consumables, especially The development speed of printing ink is also getting faster and faster. Let’s walk into digital printing equipment and understand the characteristics of different types of digital printing equipment.
ReHow RH-1918S Digital Direct Injection Printing Machine:
Through the computer and RIP control software, the digital printing machine that directly sprays the dye (or paint) ink on the surface of the fabric to form the required pattern and color is called a digital direct-injection printing machine. The digital direct-jet printing machine can be used not only for the printing of natural fiber fabrics such as cotton, hemp, silk, wool, etc., but also for the printing of chemical fibers and their blended fabrics. The main application inks are disperse, reactive, acid dyes and coatings.
ReHow RH-1918S digital direct-injection printing machine is widely used, as long as the corresponding dye (or paint) ink is selected according to different fiber fabrics, most of the textiles that can be colored can be applied to this type of digital printing machine. However, some treatments must be done before and after printing, such as sizing (or coating pretreatment agent), steaming (or baking), washing, color fixing, finishing, etc. on the fabric.
Rehow RH-1918S Digital Paperjet Machine:
Through the computer and RIP control software, the digital printing machine that prints the dye ink on the surface of the transfer printing paper to form the required pattern color is called a digital paper jet machine. The digital paper jet machine is mainly used for transfer printing of polyester fabric, and the ink used is limited to low-temperature disperse dye ink.
Since the surface of the transfer paper is relatively flat, the pattern can be kept white without multi-pass printing, so the amount of ink per unit area of digital inkjet printing is very small, and the printing speed is much faster than that of direct inkjet printing.
REHOW RH-1918S Scanning Digital Printing Machine:
Most of the digital printing machines sold and applied on the market, whether they are digital direct-injection printing machines or digital paper-jet printing machines, are scanning digital printing machines. Its characteristic is that the nozzle moves back and forth along the weft direction of the fabric (or the width direction of the paper) to print ink on the fabric or paper.
When the scanning digital printing machine is doing back and forth printing movement, due to the slight difference in the stepping speed of the guide belt, there will often be Pass pass defective products in the weft direction of the fabric, and the pass pass of some colors is not very obvious. , some colors are very prominent, if multi-pass printing is used, it can have a certain effect on masking and eliminating the pass channel.
REHOW RH-1918S Single-Pass Digital Printing Machine:
Single-Pass digital printing machine is a fixed nozzle, and the guide belt drives the fabric (or paper) to run continuously. Under the control of computer software, the ink is printed with only 1 Pass or single pass, and a color pattern is formed on the running fabric (or paper). . The nozzles of this equipment are all fixed, which can greatly increase the printing speed.
To achieve single-pass printing, the nozzles used must not only have high precision, but also have a sufficient number of nozzles. Therefore, the Single-Pass digital printing machine is expensive. At the same time, due to the large number of nozzles, the installation accuracy of the nozzles is also very high, and a slight difference in splicing will cause the printed fabric to form a warp pass defect. The Single-Pass digital printing machine has high requirements on the flatness of the fabric surface, so it is more suitable for fabric printing on paper or plain weave.
Rehow RH-1918S Scanning Single-Pass Digital Printing Machine:
Scanning Single-Pass digital printing machine is a branch of scanning digital printing machine. Its nozzle is like a scanning digital printing machine, which moves back and forth along the weft direction of the fabric (or the width direction of the paper). However, due to the relatively high precision of the installed nozzle, digital printing can be completed with a single pass. At present, this type of digital printing machine is mostly used on high-speed digital paper machines, and there are few reports on fabrics.
Single-Pass and flat (round) screen printing combined machine:
When digital printing prints a large area of background color, there are disadvantages such as poor color saturation and reverse penetration, and it is also impossible to produce special printing fabric effects such as gold and silver powder, pearlescent, and glue. In order to produce products that combine the rich colors and multi-levels of digital printing with the rich dark colors of traditional printing and special printing, some equipment manufacturers have added several sets of flat screens or Rotary screen facility for the production of large-area saturated colors and specialty print effects. The combination of these two facilities can produce more exquisite patterns and patterns than traditional printing and digital printing.
