Printing paper has a great impact on print quality, especially when using high-resolution inkjet printers, the difference between special paper and plain paper is more obvious. High-resolution printing paper specially produced by inkjet printer manufacturers, the fiber is fine and firm, which can effectively suppress the phenomenon of ink bleed. The color of the paper is white and the reflectivity is high, which can fully utilize the advantages of high resolution of the printer.
With the in-depth development of computer applications, as the most common information recording medium, the demand for printing paper has also risen rapidly. There are many types of printing paper on the market today, and the common ones are:
Paper for stylus printer: continuous format printing paper, multi-layer printing paper, high speed printing paper, color ticket paper, computer-specific stencil paper, etc.
Paper for inkjet printers: opaque inkjet paper, translucent inkjet paper (engineering copying), transparent inkjet film, coated inkjet paper, inkjet special canvas, special heavy inkjet paper, instant transparent inkjet film (adhesive sticky notes), color advertising inkjet paper, translucent light box film, inkjet special paper, glossy special paper, ultra-white coated fabric paper (grain paper, wood grain paper), standard inkjet paper, back Spray film (for light box advertising), etc.;
Paper for laser printer: transparent / single-hair laser film, xenon tube laser photo film, semiconductor red laser photo film, infrared laser photo film, laser printing film, laser offset printing plate, high-sensitivity PS plate, etc.;
Other types of paper: self-adhesive paper for electronic cutting plotter, electrostatic recording paper (high surface impedance), electrostatic drawing paper, electrocautery recording paper, high-speed drawing ink, etc. Thermal wax paper (thermal paper), thermal recording paper (high sensitivity, low sensitivity), etc.
At present, in addition to ordinary ordinary printing paper, special papers for most modern office machines in the domestic market such as: inkjet paper, glossy paper, optical drawings, transparent film, high-width film, light box sheet, fiber paper, transfer medium They are also dependent on imports.
Printing paper has a great impact on print quality, especially when using high-resolution inkjet printers, the difference between special paper and plain paper is more obvious. High-resolution printing paper specially produced by inkjet printer manufacturers, the fiber is fine and firm, which can effectively suppress the phenomenon of ink bleed. The color of the paper is white and the reflectivity is high, which can fully utilize the advantages of high resolution of the printer. Special papers are also attached to special ink beads for excellent printing results. Like the ink optimization solution in Canon ink cartridges, a dense protective layer can be formed on the special paper surface before the ink is ejected, so that the ink can adhere firmly to the film, and it will not flow around to ensure the printing effect. Long-lasting as new. Epson uses quick-drying ink that dries before the ink penetrates and chemically reacts with the special printing paper to create brilliant colors. Here we focus on the situation of inkjet paper.
First, "photo printing technology"
Before talking about printing paper, let's first briefly talk about several "photo printing technologies" that are currently used in the field of inkjet printing. The so-called "photo printing technology" refers to the color image printed by modern high-end color inkjet printers, such as photos, simply speaking, the print output resolution is between 1200dpi and 1440dpi, and uses a variety of advanced technologies and special printing paper. The color image of the output. Color inkjet printers with photo-quality output are top-of-the-line technology that meets the demanding color printing requirements of professional design or publishing companies. The advantages of high-quality inkjet printers with photo quality output are: high print quality, low noise, and high quality color output at a lower cost. The disadvantages are: slower printing speed, higher consumables, and smaller print volume. It is mainly used in professional color printing users, small offices, etc., where the printing volume is small and the printing speed is not high, and low-cost true color printout is realized.
Now "photo printing technology" mainly includes HP's Fulfill technology, Canon's ink drop adjustment, seven-color ink and four-color control technology, Epson's micro-piezoelectric, six-color printing technology, fast-drying ink, fine image half-color adjustment and In the so-called "perfect imaging system" (PPIS) composed of photo quality printing paper technology, photo quality printing paper is placed in an important position.
In addition to inkjet technology, drivers, and high-quality inks, high-quality paper must be available to form a complete "photo printing technology" system. PhotoQualityPaper, one of the four key technologies of PPIS, has a transparent adhesive layer on the surface to fix the ink, fixing the ink of different colors, and the reflection density and hue performance of the ink on the paper. It will be better than normal glossy paper. Make image performance perfect, even beyond traditional photos.
Second, the secret of printing paper
I often hear people complain that I have a high-resolution color inkjet printer, but the printed images are always not ideal. What exactly is this matter about?
Sometimes, the color inkjet printer does not print well. If the throwing operation is not correct, the driver adjustment is not accurate, and so on, the most likely reason is that the paper is not properly selected. As the saying goes: Good horses are equipped with good saddles. In order to maximize the potential of high-resolution color inkjet printers, various manufacturers have developed corresponding high-quality papers. [next]
In order to prevent the penetration of ink on the paper, on the one hand, the performance of the ink is improved, and on the other hand, the quality of the paper is improved. The ink improvement scheme adopted by Canon's BC-62 and other ink cartridges is one of the most thorough solutions. In this type of ink cartridge, a special ink optimization solution is added. Before the ink droplets are ejected, a film is formed on the paper by the ink optimizing liquid, and then ordinary ink droplets are ejected and adhered tightly to the film. Because of the protection of the film, no ink smearing occurs on the paper. In addition, this solution has also achieved unexpected benefits: because of the protective film, not only the printing effect on ordinary paper is greatly improved, but also the printing proof can realize the waterproof function. Epson has developed a quick-drying ink that penetrates quickly into the paper fibers and works with special inkjet paper to suppress the spread of ink droplets. Lexmark has developed other technologies and developed waterproof inks and paper. The research on paper by various manufacturers is very thorough and closer. The texture of each inkjet printing paper is very fine, it is not easy to smear ink, and it is whiter and brighter than ordinary paper.
The outstanding performance of color inkjet printers is related to advanced technology on the one hand, and the consumables, especially the performance and quality of print media, on the other hand. The same printer will display very different prints due to the use of different print media. effect. In general, the print media produced by each printer manufacturer is the most compatible with its own ink and printing technology, which can fully utilize the power of the printer. The user selects the print media produced by the printer manufacturer, which is the most economical in terms of ensuring print quality, performance of the printer, and risk of shopping. In addition, different media should be selected according to different printing requirements when printing. The difference in whiteness, fineness and water absorption of various papers will have a great influence on the output effect. Therefore, when selecting the printing medium, it should be specific. Specific analysis of the problem.
Today's printing media mainly consists of film and paper. The most common application for paper is paper-based printing media. Here are some of the most common print media:
(1) Photo quality inkjet paper, which is a high-resolution professional paper, ideal for image printing. The thickness of this paper is slightly thicker than that of plain paper, and it is relatively white. Selecting this side to print commercial reports, color texts, charts and various commercial statistical charts for lectures is very effective.
(2) 360dpi inkjet paper, designed for home users.
This inkjet paper is suitable for printing a variety of pictures and texts, and the printed colors are vivid and the writing is clear and beautiful.
(3) Photo quality inkjet cards, which are available in A6, 5" x 8" and 10" x 8" sizes, suitable for printing homemade postcards, greeting cards, invitations, etc. Can also be used to output a variety of electronic photos.
In addition to the above three common printing media, due to the diversified development of inkjet printer applications, printing media is also increasingly updated. Currently, the most popular inkjet printing media are photo paper, happy stickers, inkjet paper, and T-shirts. Transfer paper, inkjet transparencies and banner headline paper. The texture of the photo paper is the same as the photo that is usually washed. The media can be used as photo-printing technology to achieve the same realistic effect as the photo, and can provide four sizes from the normal photo size to the A3+, suitable for all levels of user photo printing. Need; Happy Miao Miao is a unique printing medium, users can use the more than 300 kinds of colorful background frames provided by the printer supporting software to superimpose the photos to create the most imaginative match. Miao Miao stickers; ink-jet cloth paper is a medium of A2 format three meters long with oil painting printing effect, suitable for printing a variety of large-scale photos, art design pictures; users can use T-shirt transfer paper to make their own unique style T-shirts, the effect is quite good; inkjet transparent film can provide perfect projection effect, suitable for projection, conference and advertising, the image is vivid and realistic, can print 360dpi; banner headline paper can be printed with 360dpi, 720dpi or 1440dpi, suitable for Print banners for various events.
At present, the brands of ordinary printing papers in China mainly include: “Flagship”, “Gao Le”, “Xerox”, “Dadong” and “Shuanglong”. HP, Canon, EPSON and other printer manufacturers have a full range of photo quality glossy paper photo quality glossy film, photo quality inkjet paper, inkjet transparencies, photo paper, photo quality stickers, T-shirt transfer paper Wait for paper to choose from.
Recently, Japan Olympus Optical Industry Co., Ltd. has also developed a paper that will sound, and a special scanning pen can be used to read the fine bar code printed on the paper, and the sound can be heard. The new system uses a 8.4-mm fine dot barcode to record sound, printed on paper such as books and brochures, and can be heard from headphones or speakers after reading with a scanning pen. About 15 seconds of sound can be recorded. For example, the pronunciation code of English words and example sentences printed on the language textbook can hear the pronunciation of single words and example sentences. In addition, the animal figure prints the pronunciation code of the animal's voice, and you can hear the real voice of the animal.
Since the raw materials of high-grade paper are mainly wood pulp, and pollution is inevitably generated in the process of producing paper, with the development of network and communication technology, the new "paperless green office" method is currently in the world. Rise, but in the foreseeable future, ordinary paper is still the most important medium for recording and transmitting information.
