Digital Printing Device Technology

Digital technology from MIMAKI

In the process of digital ink jet printing, the direct printing process can also be called the proofing process. The process can be described as follows: from the customer's sample to the pattern design to the sizing of the fabric, to the drying of the flat surface to the digital printing to the post-processing, That is steaming, washing and fixing. Pattern design is the pattern preparation stage. There are two forms in this stage. One is the design draft. Designers can create and modify designs, patterns, colors, etc. by various design softwares. The second is the customer's sample. Through a variety of digitizers, such as scanners, digital cameras and other patterns will be input into the computer, after computer color separation for editing. The purpose of the sizing of the fabric is: A. To prevent the fuel from being sprayed onto the surface of the cotton knitted fabric, so as to obtain a clear pattern. B, promote the dye in the hot and humid state and fiber combination, to obtain a certain color depth and color fastness. C, sizing can effectively solve the knitted fabric printing accuracy. The configuration of the sizing slurry of the fabric is similar to that of the traditional slurry, and can be proportioned according to the actual conditions of each printing plant. As for the sizing method, in order to ensure that the surface of the cotton knitted fabric is free of slack and wrinkles, a flat squeegee printing method should be adopted as far as possible, which controls the sizing amount on the fabric by adjusting the squeegee pressure and the angle of the squeegee. When printing, the pattern should be sprayed on the side of the sizing of the fabric, which can improve the fineness and vividness of the pattern. In the printing stage, cotton knitted fabrics generally use TX2-1600S, which can be sprayed. If printed on a softer, more easily deformable fabric and need to be better conveyed by the crawler, the TX3 machine is more suitable. The post-processing stages include steaming, washing and drying. Washed ears listened to the drying process to wash your ears with cold water first, then wash with warm water, then soaping (soap 1g/1), then warm wash, and then cold water wash, and finally drying.

In the entire process, the key to proofing is color toning. In general, the use of color cards to control the color of cotton knit digital inkjet printing patterns is a simple, intuitive, and effective method. Color cards commonly used in digital inkjet printing include RGB color cards, CMYK color cards, LAB color cards, and PANTONE color cards. Compare the customer's sample color with the color card, find the same or similar color code in the color card, record the corresponding value or number, and input the color value in the graphic software to adjust the image color. The second key is to simulate the production of large samples. Since computer printing is not limited by color, millions of colors can be printed, and almost natural colors can be reproduced on textiles. But taking into account the actual production process behind the restrictions, generally we consider the next process in the production of samples, especially the printing of some high-precision moiré watercolor patterns, first of all through the computer color processing technology to simulate the traditional printing of the color number.

The workflow of digital printing is basically unchanged, and different digital printing machines may bring different printing effects and work efficiency. Here, I recommend the outstanding performance of the digital printing machine of MIMAKI series.

First, TX2-1600 digital printing machine

TX2-1600 digital printing machine's main performance characteristics include: 1. New and improved platen design: When high-speed output, it can effectively flatten all kinds of fabrics, and the spray head will not touch the fabric. 2. High efficiency and high quality of digital printing: Samples can be provided in the shortest time. And can print a full-color high-quality color pattern (traditional printing can not be made). 3, advanced ink cartridge design: TX2-1600 uses two 8-color configuration, can choose two different inks at the same time, the color field and wider application. 4. Automatic cloth collecting device: It can fix the reel to prevent the cloth from being misaligned. The cloth maintains the straight-line path during the conveying process and improves the output quality and efficiency. 5 Fabric offset correction device: The fabric is offset due to unevenness on both sides of the fabric. This device automatically corrects the fabric framer immediately to keep the fabric roll straight. 6, IEEE1394 interface FireWire transmission: IEEE1394 interface FireWire transmission up to 400MB/sec.

Second, TX3-1600 digital printing machine

Based on the TX&TX2, the following improvements have been made, and the following unique features: 1. Unique ink-jet technology: The use of micro-piezoelectric variable ink droplets (using three ink droplets at the same time) inkjet technology, greatly improved the image The accuracy and quality. The highest precision up to 1440dpi. 2, TX3-1600 unique nozzle automatic detection system: MIMAKI's self-developed nozzle detection system, to achieve the equipment to eliminate disconnection and other faults, so as to achieve, long time, batch of automated production. 3, the use of 1000CC large-capacity ink cartridges: can achieve long unattended continuous output. 4. There are two levels of ink supply system: the ink supply system first draws ink from two sets of ink cartridges to the common sub ink chamber, and then the sub ink chamber supplies ink bags and nozzles, thus ensuring that the machine can perform high speed for a long time. Printout. 5, the unique feeding device: TX3-1600 belt conveyor feeding system, flexible fiber can also stabilize the print output. A unique sensor is designed at the seam of the belt to eliminate the errors caused by the belt seams through software control. 6, has a complete set of matching dyes: The current MIMAKITX3-1600 can be used with four stable and reliable digital printing dyes. Reactive dyes used in cotton printing include acid dyes for silk printing, disperse dyes for chemical fiber, and newly introduced coatings that do not require pre-treatment or post-treatment. 7. Dual ink supply can be used at the same time: two different inks can be used on the same machine, eliminating the cumbersome operation and risk of ink replacement when printing different fabrics. 8, high-speed output: the highest speed per hour up to more than 50 square meters. 9. The specially designed belt clips for the conveyor belt prevent the possibility of fabric deviation.

Third, the GP series platform inkjet printing machine - clothing digital printing machine

GPSeries is a platform digital printing machine developed by MIMAKI (Japan), which can be used on T-shirts, garments, fabrics, clothing and other flat surfaces. It uses “water-based dyes” and paints to spray directly on fabrics without pre-treatment. After proper heating (iron or heat conveyor belt) cures, it will prevent fading and water. On the basis of this, the D model has added the discharge function, which can print colorful patterns on dark clothes, thus greatly increasing the application range of the GP series, making digital printing a major breakthrough in replacing traditional screen printing. Once confirmed MIMAKI's king style in printing technology. Its main features are:

1. Dye-stained paint (coating), direct printing: adopts double-colored advanced dyeing dyes, can be directly printed on T-shirts/garment and other diversified individual products, without sizing, drying and other pre-processing, only need to do pressure after printing. Hot or dry.

2. Intelligent thermostatic heater: With smart thermostatic heater, the adhesion of ink on the fabric can be enhanced, and the temperature can be set separately according to the fabric.

3. High-precision sensor: There are newly designed sensors on both sides of the printing platform, which can automatically detect the thickness of the fabric effectively, achieving high-quality printing effects, effectively preventing the phenomenon of “squeezing nozzles” and prolonging the life of the nozzles. .

4. Innovative panel design: Innovative and versatile panel design, easy to learn, allowing you to use more handy.

5. High-quality printing effect: The use of micro-piezoelectric variable-drop inkjet technology has greatly improved the accuracy and quality of the image. The output resolution can reach 720720 dpi, which can quickly solve the production of multiple products and small batches.
