What are the characteristics and advantages of digital printing(part -2)?
1、 Different references
A. Digital printing: with the continuous development of computer technology, digital printing is a kind of high-tech product which integrates machinery, computer and electronic information technology.
B. Garment printing: it's a garment making process. Dye the fabric into a single color and print the pattern on the fabric.
2、 The principle is different
A. Digital printing: the pattern is input into the computer in digital form, edited and processed by the computer printing color separation and draft drawing system (CAD), and then the special dye is directly sprayed onto the textiles by the micro piezoelectric ink jet nozzle controlled by the computer to form the required pattern.
B. Clothing printing: according to the sublimation characteristics of some disperse dyes, the transfer paper printed with pattern pattern is closely contacted with the fabric. Under the condition of controlling a certain temperature, pressure and time, the dye is transferred from the printing paper to the fabric, and enters into the interior of the fabric through diffusion, so as to achieve the purpose of coloring.
3、 Different advantages
A. Digital printing: the dye solution is directly put into the special box and sprayed on the fabric according to the demand, which is neither wasted nor polluted by waste water. It eliminates the discharge of dyeing liquor from the printing machine washing in the sizing room, so as to achieve no pollution in the printing process. The film is also omitted. Material consumption of wire mesh, silver cylinder, etc.
B. Garment printing: the base color of the fabric is white or mostly white, and the printed pattern looks lighter from the back than from the front.
