With the further development of computer applications, the demand for printing paper has rapidly increased as the most common information recording medium. There are many types of printing paper on the market today. Common ones are:
Paper for stylus printers: continuous format printing paper, multilayer pressure sensitive printing paper, high-speed printing paper, color ticket paper, computer-specific typing wax paper, etc.;
Paper for inkjet printers: opaque inkjet paper, translucent inkjet paper (engineering copy), transparent inkjet film, coated inkjet paper, inkjet special canvas, special heavy inkjet paper, instant transparent inkjet film (Adhesive sticky note), color inkjet ink-like paper, translucent light box film, inkjet paper, gloss special paper, ultra-white coated cloth paper (textile paper, wood grain paper), standard inkjet paper, back Spray film (lightbox advertising);
Paper for laser printers: transparent/single-lens laser film, neodymium tube laser beam, semiconductor red laser beam, infrared laser beam, laser film, laser offset, high-sensitivity PS, etc.
Other types of paper: Self-adhesive paper for electronic cutting plotters, electrostatic recording paper (high surface impedance), electrostatic drawing paper, electrosurgical recording paper, high-speed drawing ink, etc. Thermal stencil (thermal paper), thermal recording paper (high sensitivity, low sensitivity) and so on.
In addition to the general ordinary printing paper, most of the special papers used in modern office machines on the domestic market include: inkjet paper, high-gloss paper, light drawings, transparencies, high-width films, light boxes, fiber paper, and transfer media. All of them also rely on imports.
Printing paper has a great impact on print quality, especially when using a high-resolution inkjet printer. The difference between special paper and plain paper is even more pronounced. Inkjet printer manufacturers specialize in producing high-resolution printing paper with dense fibers, which can effectively inhibit the phenomenon of ink bleeding. The color of the paper is white, and the reflectance is high. The advantage of the high resolution of the printer can be fully realized. Dedicated paper is also attached to a special ink bead for excellent printing results. Like the ink optimization solution in Canon ink cartridges, a dense protective layer can be formed on the dedicated paper surface before the ink is ejected so that the ink can firmly adhere to this layer of film and will not flow around to ensure the printing effect. Long-term as new. Epson used a quick-drying ink that dried before the ink penetrated and chemically reacted with special paper to create a bright color. Here we focus on ink jet printing paper.
I. "Photo Printing Technology"
Before talking about printing paper, let us briefly talk about some of the "photo printing technologies" that are currently used in the field of inkjet printing. The so-called "photo printing technology" refers to the use of modern high-end color inkjet printers to print color images such as photos, in short, is the print output resolution between 1200dpi ~ 1 440dpi, and the use of a variety of advanced technologies and special printing paper The output color image. Color inkjet printers with photo quality output are all state-of-the-art devices that fully meet 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, more expensive consumables, and smaller print volume. It is mainly used in professional color printing users, small offices, etc., with a small amount of printing and a low printing speed, thus realizing low-cost, true color printing. Currently, "photo printing technology" mainly includes HP's Fola Technology, Canon's ink drop adjustment, seven-color ink and four-color control technology, Epson's micro-piezoelectricity, six-color printing technology, fast-drying ink, and fine image half-tone adjustment. The so-called "Perfect Image System" (PPIS) composed of photo-quality printing paper technology, etc., places photo-quality printing paper in an important position.
In addition to inkjet technology, drivers, and high-quality ink, there must be high-quality paper to form a complete "photo printing technology" system. PhotoQuality Paper, one of PIS's four key technologies, adds a layer of transparent adhesive that fixes the ink on the surface, fixing different colors of ink, and the density and color of the ink on the paper. Performance will be better than general glossy paper. Make the image performance perfect, even beyond the traditional photo.
Second, the secret of printing paper
Often hear people complain that they have a high-resolution color inkjet printer, but the printed picture is always not ideal. What exactly is this matter about?
Sometimes, color inkjet printers do not print well. If you leave out the human factors such as incorrect operation and inaccurate driver calibration, 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 corresponding to them.
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. Canon's BC-62 and other ink cartridges are one of the most thoroughly implemented solutions. In this type of ink cartridge, a special ink optimization liquid is added. Before the ink droplets are ejected, a thin film is formed on the paper by the ink optimization liquid, and then ordinary ink droplets are sprayed and tightly adhered to the film. Because of the protection of the film, ink picking does not occur on the paper. In addition, this scheme has also obtained unexpected results: Because of the protective film, not only the printing effect on ordinary paper is greatly improved, but also the printing proof sheet can achieve the waterproof function. Epson developed a quick-drying ink that can quickly penetrate the paper fibers and cooperate with special inkjet paper to suppress the spread of ink droplets. Lexmark used other technologies and developed waterproof ink and paper. The research on paper by various manufacturers is very thorough and closer. The texture of each special ink-jet printing paper is very detailed, not easy to ink, more white and bright than ordinary paper.
The outstanding performance of color inkjet printers on the one hand is related to advanced technology, and on the other hand also depends on the consumables, especially the performance and quality of the print media. The same printer will show a very different printing due to the use of different print media. effect. Under normal circumstances, the print media produced by each printer manufacturer is the most compatible with its own ink and printing technology, and can fully utilize the efficacy of the printer. The user selects the print media produced by the printer manufacturer and is the most economical measure in terms of guaranteeing the print quality, the performance of the printer, and the risk of shopping. In addition, when printing, different media should be selected according to different printing needs. Differences in the quality of various papers, such as whiteness, fineness, and water absorption, will have a great influence on the output. Therefore, when selecting the print media, it should be specific. Specific analysis of the problem.
Nowadays, there are two major types of print media, namely film and paper. The most commonly used by users is paper-based print media. Here are some of the most common print media:
(1) Photo-quality ink-jet printing paper, which is a high-resolution professional paper, is an ideal medium for image printing. The thickness of this paper is slightly thicker than plain paper, and it is relatively white. Selecting this side to print commercial reports, colored texts for lectures, charts, and various business statistics shows excellent results.
(2) 360dpi inkjet printing paper designed specifically for home users. This ink-jet printing paper is suitable for printing various pictures and texts, vivid colors and clear and beautiful handwriting.
(3) Photo Quality Inkjet Cards This pure white inkjet professional card is available in A6, 5" x 8" and 10" x 8" sizes for printing homemade postcards, greeting cards, invitations, and more. Can also be used to output various electronic photos.
In addition to the above three kinds of ordinary print media, due to the diversified development of inkjet printer applications, the print media has also been updated. Currently, the popular inkjet print media includes photo paper, papers, inkjet paper, and T-shirts. Transfer paper, inkjet transparency, banner banner paper, etc. The texture of the photo paper is the same as that of a normal photo, which can be used with the photo quality printing technology to obtain the same realistic effect as the photo, and can provide four sizes from the normal photo size to the A3+, suitable for the photo printing of all levels of users. Needs; Happy Miao stick is a unique print media, users can use the printer supporting software provides more than 300 kinds of colorful background frame and photo overlay, the most imaginative collocation, made of a very attractive personality charm Miaomiao stickers; inkjet textured paper is an A2 format three meters long media with oil painting effect, suitable for printing a variety of large photos, art design pictures; users can use T-shirts transfer paper production has its own unique style T-shirts, the effect is quite good; inkjet transparency can provide a perfect projection effect, suitable for projection, meetings and advertisements, vivid images, printable 36 0dpi; banner banner paper can be printed 360dpi, 720dpi or 1440dpi, Suitable for printing banners for various events.
At present, the domestic brands of ordinary printing paper mainly include: "flagship", "Gao Le", "Xerox", "Dadong", "Shuanglong" and so on. HP, Canon, EPSON and other printer manufacturers have a wide range of photo quality glossy paper photo quality glossy film, photo quality inkjet paper, inkjet transparency, photo paper, photo quality sticker paper, T-shirt transfer paper Paper is available for selection.
Recently, Japanâ€™s Olympus Optical Industry Co., Ltd. has also developed a sound-generating paper that can be heard using a special scanning pen to read thin barcodes printed on paper. The new system uses a 8.4 mm wide dot bar code to record sounds, print on papers such as books and pamphlets, and hear sounds from headphones or horns after scanning with a pen. Approximately fifteen seconds of sound can be recorded. For example, the pronunciation of English words and example sentences can be printed on the language textbooks, and the pronunciation of single words and example sentences can be heard. In addition, the animal map can be printed with the pronunciation code of the animal's cry, and the animal's real cry can be heard.
As the raw materials of high-grade paper are mainly wood pulp, and pollution is unavoidable in the process of producing paper, with the increasing development of network and communication technologies, the new type of â€œpaperless green officeâ€ is currently on a global scale. Rising, but in the foreseeable future, ordinary paper is still the most important medium for recording and transmitting information.
