The ink-jet printer to print from the resolution of 360dpi, 600dpi, 720dpi, 1200dpi, 1440dpi to the present maximum of 4800dpi, print accuracy of the continuous drive to enhance the print quality of an increasingly perfect. Dpi represents every inch in the number of ink to print, if we do not consider the Mexican point of overlap between the issues, described the figures dpi can upgrade to an unlimited, but this time it will not improve the print quality, or even decline. Therefore, in order to effectively enhance the value of the dpi, must be small enough ink spots on the premise, that is small enough to drop the volume. Only a small drop enough, in order to achieve higher precision printing, to improve the quality of the final print to play a real role. On
said that it is necessary to drop the size of the print head. Print is the first ink-jet printer's core technology, the application of the current classification of the main heat into the bubble-Wei piezoelectric print head and print head. In the normal concentration of coloring, when the ink-jet or slightly less than 1, the human eye can not see the Mexican point. The lower the concentration of color, the more it is not easy to form found in the ink, it reduces the Keli Gan, the eye looks of the Mexican people than their actual size smaller. So far, almost all products have reached 5 or slightly drop control technology, able to basically meet the people's day-to-day photo printing needs, if we can do 3 or slightly below, then the accuracy of the output will be better. From the overall effect, if the printer can meet the 4800 × 2400dpi and do 3 or slightly below the drop control, then the effect of printing photos at this time do not lose Caikuo in digital technology. However, the decision
In addition to the print quality of printing technology and also paper, ink has a great deal.
In short, the original manufacturer's printer technology. Ink and paper technology has its own technology compatible with the characteristics of different brands of supplies on the compatibility is not good. As a result, the purchase of ink-jet printers need to buy the whole set of supplies, because with digital print Museum is the pursuit of results.
Caikuo Caikuo into digital and film Caikuo. However, the two different imaging principle. Film
Caikuo machine works. Si-lan (optical sensor is, there are three groups of red-green-blue) through the film color temperature reaction, Caikuo through the automatic processing machine plate color, exposure time will be fed back to yellow green electrical goods (filter) and the shutter. Chuan is the lens through photographic paper (based on the principle of photo paper) after a trough of medicine (Color drift and the drying lake) = into a phase.
digital Caikuo and its largest point difference is more than a digital computer part of the Slide and treatment system. Caikuo film and the latter part of the same machine.
Caikuo digital prints from digital imaging equipment (exposure) Technically, there are three: CRT (cathode ray tube), LCD (liquid crystal), LASER (laser) of the three.
from the purchase price on, the ink-jet printing and level Caikuo is not a product. If it is not a professional image, only the pursuit of print speed and the general effect of Penda sufficient to meet demand.
