Printing paper: important factors affecting the printing effect (top)

Subdivided printing paper type

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:

Needle printer paper: continuous format printing paper, multilayer pressure sensitive printing paper, high-speed printing paper, color ticket paper, computer typed wax paper and so on.

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) and so on.

Paper for laser printers: transparent/single-lens laser film, neodymium tube laser photolithography, semiconductor red laser photolithography, infrared laser photolithography, laser printing film, laser offset printing, and high-sensitivity PS.

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.

"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.
