2. HP: HP is very popular in China for its high-quality products and services. It also has its own uniqueness in technology. The patented HP photo color enhancement technology has a big impact on the traditional DPI technology. On this basis, HP has developed the "Fulitu" technology (PhotoRetII) and the second Generation intelligent color enhancement technology (ColorSmartII). The second-generation color level enhancement technology enables the nozzle to emit extremely tiny ink droplets of 10PL that are impossible to see with the naked eye. It is precisely because of such small ink dots that more changes can be produced in each pixel, reflecting the Hundreds or thousands of layers of color gradient changes enable satisfactory printing effects on ordinary paper. The second-generation intelligent color enhancement technology allows users to easily print the best results on various printing media without having to bother adjusting various printing parameters. This allows users to print a single copy that contains images, charts, color text and Its convenience is better reflected in the documents with black and white text.
3. Epson: When Canon and HP were both proud of their thermal inkjet technology, Epson developed more advanced micro-piezoelectric technology, and later based on micro-piezoelectric technology Ultra-micro piezoelectric inkjet printing technology and PPIS (Perfect Imaging System) technology were also launched. Micro-piezoelectric printhead technology uses the characteristic of crystals to vibrate at a stable frequency when powered on. By changing the voltage and adjusting the frequency of crystal vibration to accurately control the size of ink droplets and the speed of ejection, the ink ejected through this technology Only 1/3 of the usual size makes the shape of the ink droplets more regular, the positioning more accurate, and the resolution is also improved. This result enables high-quality printing and high-speed printing to coexist. The advantage is that it reduces ink consumption and reduces printing costs.
4. Lexmark: Lexmark’s products are not very familiar to the majority of Chinese users. This may be related to its late entry into the Chinese market, but its international status is still very high. Yes, it is a subsidiary separated from the blue giant IBM, so it can compete with the above three companies in terms of technology and products. Lexmark's patent is excimer laser cutting print head technology, which can combine the ink ejection hole and the pressurized chamber for ink to the nozzle into one, so that the diameter of the nozzle is only one micron, so printing under this nozzle The resulting pattern is very ideal. Lexmark has also developed waterproof ink. Using this ink with a high-resolution inkjet printer, the printing effect can be completely comparable to that of laser printing equipment.
Purchasing principles The first thing to explain is that printers are the same as CPUs, hard drives, etc. They may fall behind soon after purchasing, because new technologies are emerging one after another. Use them as soon as you buy them, otherwise you might as well Don't buy it. Determine the actual use of the printer you want to buy, and choose the printer of the grade you need based on it. If it is for general use, do not buy a professional printer. If you buy the printer mainly to print black and white documents, and are concerned about the quality of the printed images If the requirements are not particularly strict, an economical color inkjet printer is your first choice; if the printer is mainly for office use, a practical color inkjet printer that takes into account quality, functionality and speed is your natural choice; if it is for office use For professional purposes such as design and proofing, only a professional color inkjet printer can meet your requirements.
Each of them has its own characteristics when it comes to the selection of print heads. Generally speaking, print heads using piezoelectric technology are better. In addition, the more nozzles on the print head, the faster the printing speed, and the finer the nozzles, the more beneficial it is. Increase printing resolution. Nowadays, most general printers use four-color ink cartridge designs. When purchasing, try to buy this type, because its performance is much higher than three-color ink cartridges.
