Digital Printing: Equipment technology articles
Digital technology from MIMAKI Digital inkjet printing technology process, the direct printing process is called proofing process can be roughly described as follows, the flow pattern from your sample to the sizing design to fabric, then drying to digital printing to the formation After the treatment, that is steaming? washing and fixing. Graphic design is design preparation stage, the stage has two forms, namely, design draft, designers can design software through a variety of patterns? Flower? Color with random creation and modification, etc.; Second, customers like: Yes through a variety of digitizers, such as scanners? digital cameras will be input into computer design, color separation through the computer for editing. The purpose of sizing material is: A, to prevent the printing of cotton knitted fabric to penetration of surface fuels to gain a clear pattern. B, promote the dye in hot and humid condition, and fibronectin, was a certain color depth, and color fastness. C, after sizing can effectively solve the knitted fabric printing accuracy. Fabric configuration and sizing of traditional pulp slurry rather, can match the actual situation in various printing plants. Speaking of sizing methods, in order to ensure the surface of cotton knitted fabric and fold without skew, should be printed by plate scraping method, the method by adjusting the Scraper Pressure and the blade angle to control the amount of the fabric of the band Pulp. Should be sprayed in the pattern of printing and sizing in the fabric side, can improve the pattern fineness and brightness. In the printing stage, cotton knit fabrics generally use TX2-1600S, you can print, if printed on relatively soft? Easy deformation of the fabric, the need to better track delivery, then the more appropriate use of TX3 machines. Post-processing stage for the steaming process and washing and drying. Drying process of water ears ears with cold water for the first, and then warm water, then wash with soap (liquid soap 1g / 1), and then warm water, then cold water washed out, the final drying.
In the whole process, the key for the color proofing, in general, use Color Card To control cotton knit color digital printing is a simple pattern? Intuitive? Effective way. Commonly used in digital inkjet printing with RGB color card color card? CMYK color card? LAB PANTONE color cards and color cards. The customers to sample the color and color card comparison, in color and pattern color card found in the same or similar color, to record the corresponding value or number, enter the color in the graphics software to adjust the image color values. The second key is to simulate a large sample production results. Because computers are produced without color restriction, you can print one million kinds of colors, almost the color of the natural world can be in Textile Products on reproduction. However, considering the actual production process behind the restrictions, generally we have to consider when making sample after the procedure, in particular, a number of high-precision printing watercolor moire pattern, the first color separation through computer processing, simulation of traditional printing chromatic few.
Digital printing workflow is essentially the same, not the same as the digital Printing machine May bring different printing effect and efficiency. In this, I recommend to everyone MIMAKI series of digital printing machine of superior performance
1, TX2-1600 digital printing machine TX2-1600 digital printing machine Main features include a new improved plate design: high-speed output can be effectively flatten all kinds of fabrics, sprinklers will not run into cloth. 2, digital printing efficiency, and high quality: can be provided in the shortest time comp. And can print a full color high-quality color-rich designs (traditional printing can not be produced). 3, advanced Ink Pack design: TX2-1600 8-color configuration with two, which can use two different ink colors and application of a broader area. 4, automatic income distribution device: can be fixed roll, go the wrong prevent fabric, fabric to keep the process in the transmission line behavior, improve the output quality and efficiency. 5 fabrics offset correction device: the unevenness of fabric produced by feeding both sides of left and right shift, this device automatically and immediately amend rack cloth, enabling cloth roll cloth to keep going straight. 6, IEEE1394 FireWire interface to transfer: IEEE1394 FireWire interface to transfer up to 400MB/sec.
