At present, heat transfer is the most common application process in the field of digital printing. It has a short process, convenient operation, and good adaptability to fabrics. However, the penetration of the dyes of some merchants is poor, which is easy to causes the phenomenon of silk turning. The phenomenon of exposed white cores under the tension of elastic fabrics, and even the heat migration color accuracy on some sensitive fabrics are poor.
In the past few years, the market for directly (DTG) inkjet printing machines has developed steadily. The demand for DTG inkjet printed machines does not only come from the clothing silk net printing merchants seeking small-scale production and one-time processing. Those merchants who specialize in making labels, drawing, and promoting publicity materials also responded positively.
Digital printing, first pre-processing the fabric, and then letting the fabric pass at high speed through inkjet printed machines. The textile digital printing machine uses a digital printed flower type, reads the correct color information, and prints the color to the fabric. The fabric uses the tiny ink drip produced by the nozzle. The nozzle is located on the top of the fabric.
Textile digital printing materials In textile digital printing, a large number of nozzles of the printed machine ensure the printed high-quality flower design and fast production speed. However, because the nozzle is too close to the fabric, some fabrics cannot be used for digital printing.
Common problems of digital printing include: the color depth of printing is too deep and the paper cannot be dried in time, resulting in the decline of the fastness index. Therefore, under normal circumstances, the total value of CMYK (printing chromatic mode) should not exceed 280. The distance between the inkjet head and paper should be reduced as much as possible to improve clarity without affecting product quality. In addition, the dye fineness and surfactant of prepress ink will affect the stability of jet printing; It is difficult to judge whether the coating of heat transfer paper is uniform; The color difference between the front and back in spray printing leads to uneven after printing, paper rubbing and other problems.
Digital ink-jet printing technology refers to controlling the nozzle by computer micro voltage to spray ink directly onto the medium to be printed for direct printing. Digital printing technology is a high-tech product integrating machinery, computer, and electronic information technology with the continuous development of computer technology. The emergence and continuous improvement of this technology have brought a new concept to the textile printing and dyeing industry. The garment printing machine, with its advanced production principles and means, has brought an unprecedented development opportunity to textile printing and dyeing. With the increasing development of digital printing technology, the products of digital printing are becoming more and more abundant.
With the tightening of environmental protection policies, the transformation of printing and dyeing environmental protection has been significantly accelerated. Science and technology, fashion, and green are becoming the new labels of this industry. The continuous emergence of enhanced HD digital printing technology and the upgrading of professional Rip (raster image processing) software solutions have produced fabrics that meet the highest retail quality and durability standards. Therefore, digital printing has shown explosive growth in recent years, which has brought new vitality to the green development of the industry.
