Color inkjet printing digital color printing machine is an UV flatbed printer economical, efficient output device, inkjet printers are familiar with many users. Especially with the rapid development of digital color printing technology to produce their own digital photos concept has gradually by the majority of consumers accepted, widely used in various industries. That in the end is what makes inkjet printers can output beautifully bright pattern? Print quality difference between the different models is how to cause it? Explore these issues, it is necessary to parse Digital Caiyin nozzle print accuracy with nozzle relationship.

Print accuracy is in fact not universal flatbed printer basis of technical indicators. In the process of the development of digital color printing machine, printing precision has been a technical indicators of user concern, manufacturers also focus on publicity in this regard. Indeed, 360dpi, 600dpi, 720dpi, 1200dpi, 1440dpi, 2880dpi led to the highest 5760dpi, the rise of the printing precision print quality is increasingly perfect. However, simple dpi digital print quality can not explain the most fundamental problem. The Dpi represent to be able to print the
number of dots per inch, and if we do not consider the problem of overlap between the dots, this description dpi digital infinitely improved print quality does not improve, or even decline. Therefore, to effectively enhance the values ​​of dpi, must be small enough ink dots on the premise that a sufficiently small droplet size. Only in the case of ink droplets are sufficiently small, the realization of a higher printing accuracy is real, to be able to improve the final print quality of play.

In addition, we know that similar, inkjet printers and display equipment, printing equipment, through a combination of limited pigment arranged to show the world's thousands of colors, such permutations are not random, by precision calculations obtained . Since it is calculated, there must be an assumption that all dots are arranged in accordance with certain rules on paper (or other medium), and the shape of each dot is basically consistent, predictable. If with paper position of the ink droplets can not be precisely controlled, or the formation of an ink dot is too irregular, or when forming ink dots connected with the location around unforeseen splash "satellite" drops (some traditional thermal bubble-jet ink printers often have this problem), then the calculation of the high level of accuracy can only be alone make up on this basis to achieve higher print accuracy (dpi) and can not really improve the final print quality.

Therefore, to reduce the drop volume, precise control of ink droplet with paper position and shape of the dots, to reduce the splashes of ink droplets became inkjet printer manufacturers in improving the print quality is important to overcome technical problems. In this regard, EPSON is one of the most successful manufacturers.

EPSON distinctive micro piezoelectric nozzle technology, the piezoelectric device is controlled by the electric pulse signal, the formation of the corresponding size of the pressure of the ink, so that a corresponding volume of ink droplets ejected from the nozzle. Compared with the traditional thermal bubble type nozzle technology, since the precise adjustments easier telecommunications number control, more precise control of droplet size.EPSON many models minimum drop volume several times reached 4 picoliter individual models reached a record
3 picoliters, reportedly new 1pl new products is also possible in the near future launched. It is these industry-leading indicators to ensure the the EPSON product can achieve true high-precision printing.

Droplet control, Micro Piezo some innate special advantages. We know that, due to the tiny ink droplets of ink nozzles is very fine, much finer than a human hair. So subtle local nozzle ink surface tension of the liquid level is very impressive, general ink droplets irregular shape, ink droplets splashing problem largely are the liquid surface tension at play. The conventional thermal-bubble type nozzle is localized heating of the ink, the bubble generation, the bubbles burst, so that the ink ejected from the nozzle. In this way to overcome the above problem approaches less. Micro Piezo by piezoelectric chip control, first ink droplets pull back, outward Tuishe out, like an arrow, rounded dots emitted. This is the hot bubble nozzle absolutely not achieve. Rely on the push and pull the two directions of movement, the piezoelectric micro nozzle can achieve the unique liquid level control technique, and minimizes the impact of liquid surface tension on the drop shape, is not formed splash, but also makes the ink droplet stable jet direction, a more precise location of the dots with paper.

It is because of these technical features, the EPSON Micro Piezo print head to print dots arranged in order and shape a unified, and there is no excess splashing dots, so that the final printed product color accuracy and bright, level of detail, expressive pole strong.

Micro Piezo inkjet technology, eco solvent printer there are some other features, such as the ability to accurately achieve intelligent ink droplets transform function. Another point to note is that many factors affect the printing precision: print speed, of course there will be different levels of accuracy; different types of nozzles frequency will vary; the print algorithm differences; whether application smart drops transform ; paper speed.
