Basic introduction to Retractable Banner printing technology
Similarly, induction thermal Retractable Banner inkjet technology (thermal Retractable Banner inkjet technology) is the use of a thin-film resistor, is less than 0.5% in your ink-jet ink heated, forming a bubble. The bubbles at an extremely fast speed (less than 10 microseconds) extension, forcing the ink from the nozzle spray. Bubble continues to grow the number of microseconds, it went back on the resistor.
When bubble dies, the ink nozzles will retract. Then surface tension creates suction, pull new inks added in ink-jet area. Induction thermal Retractable Banner inkjet technology, that is, by circulating the technical procedures of such a consolidated schema. Piezoelectric Retractable Banner inkjet technology, the ink is one and induction thermal Retractable Banner inkjet technology similar to the nozzle of the spray, but the ink drop formation is made by narrowing the area to ink-jet formation.
Narrowing of the emitting region, is imposed through the exhaust area within one or more voltage to control of piezoelectric plate. Because the ink can undergo chemical changes at high temperature, stable nature, so making the color authenticity would be subject to a certain degree of influence; the other hand because the ink through the bubbles exhaled by, bad grasp the direction and volume of ink particles size, printing lines, uneven edges easier, a certain degree of affecting print quality, this is it's shortcomings. Micro Piezo print head technology is the use of Crystal when pressurized discharge characteristics.
State at room temperature stable ink-jet out. It has characteristics of the ink control ability, easy to implement 1440dpi print quality with high accuracy, and no heating when the micro piezoelectric Retractable Banner inkjet, ink would not have occurred because the heated chemical changes, it greatly reduces the requirements for ink. At present, Epson, Canon, HP, representatives of three companies produced liquid Retractable Banners inkjet printers market
Ink-jet printer Mainstream products.
Retractable Banner inkjet printers when you print an image, requires a series of complex procedures. When fast swept across the paper when the printer nozzle, countless nozzle above it will spray out a myriad of small ink droplets, thus composed of pixels in an image. Printer head, and typically have 48 or more than 48 independent nozzle spraying a variety of different colors of ink.
Such as Epson Stylus Photo 1270 48 nozzles that can squirt, respectively 5 different colors: cyan, magenta, yellow, light blue green and pink and purple, and there are also emit black ink 48 nozzles. In General, the more nozzles, print more quickly. Dripping ink of different colors in the same context, the formation of different complex color. With a microscope can see yellow and blue-violet ink as well as into local green, so we can think so: the base color is covered in ink-jet printed layer formation.
By observing the simple four-way color ink jet work, we can easily understand how Trade Show Retractable Banner printers work: 0 to 4 on each pixel on which the ink drop coverage. As shown in the following figure, different combinations can produce more than 10 different colors. Some printers can also be through a combination of color, such as "blue-green, and black" or "red-purple, yellow, and black" combinations, resulting in 16 different colors.
