Talking about the quality of inkjet printers

The quality of inkjet printing should be the primary factor in the selection of a printer. However, different users should first consider the following quality assessment factors when selecting such printers:

(1) The inkjet printing method belongs to monochromatic dithering output analog grayscale, and its quality mainly depends on various parameters such as the resolution, grayscale, color gradation, saturation and color temperature of the printer in black and white text and color image output. In theory, the higher the resolution, the better the print quality. Such as Lexmark Z52 color and black resolution up to 2400 × 1200dpi, with support for sRGB color space, full support for Microsoft Windows and office applications such as color matching, using ICM or Corlor Sync color management capabilities, can make printers, monitors, The color space of scanners, digital cameras, and other devices is completely matched.

(b) The quality of the printer can be determined through the comparison of printer ink performance. In addition to increasing the print resolution, the user can also increase the number of ink colors, reduce the size of the ink droplets, and use advanced algorithm software to control drop placement and improve ink quality. Ink performance and the use of special printing paper and other ways to achieve, inkjet printer high-quality output is a system engineering that requires a comprehensive improvement in hardware and software performance.

The more color types of ink, the more colorful the original manuscript is. Everyone knows that low-end inkjets are three- or four-color printers and medium-to-high-end printers are six-color (or even more) printers. Like paintbrushes, the more types, the more colorful they can display. Many printers currently support four-color printing, and the Lexmark Z52 supports photo-grade six-color printing (yellow, magenta, cyan, black, light magenta, light blue), which will make the print effect comparable to the photo.

Of course, there is another factor that is the quality of your manuscript. There is an original manuscript with vivid colors and rich layers. It is the premise of obtaining perfect output results. If the originals that need to be output are overkill, then how can the back-end equipment be improved and the results be even better? Microscopic.

Recently, many manufacturers have introduced a variety of advanced technologies to improve print quality. The Lexmark Lexmark's excimer laser-printing printhead technology combines the ink jet nozzle with the ink-to-nozzle pressurization chamber, breaking through the traditional technique of splicing the nozzle with the pressurized chamber. Now the diameter of the nozzle is only 1 Micron's precision treatment process is as fine as one-sixtieth of a hair. The precise nozzle can effectively reduce the ink droplets that are ejected, making the printing effect more clear and delicate. Lexmark Lexmark has also developed a special black dye that can be used instead of liquid dyes to keep the very small carbon particles in the ink suspended by a dispersant so that it will not be deposited by gravity and therefore has excellent water resistance. . Proofs printed with this type of ink will remain clear even if they are soaked in water for a week.
