[Concept] Print a printer using dye-sublimation technology. ======================== Works Sublimation technique is the use of the thermal energy of the pigment is transferred to the print medium, the gradation of each color by the change in temperature of the print head control, can have a maximum of 256-level. --------------------- The solid pigment (referred to as color volume) provided in a drum, the drum installed above there are tens of thousands of semiconductor heating element when the heating element temperature rises to a certain extent, it can be solid pigment is directly converted into the gaseous state (solid state without passing through the liquefaction process called sublimation becomes gaseous, so the printer is referred to as thermal sublimation printer), the gas is then jetted onto the print medium. --------------------- Each semiconductor heating element can be adjusted 256 temperature, and thus be able to adjust the color ratio and the degree of shading true color photo effect, achieve continuous tone. --------------------- 3, because the pigment is applied to the paper, therefore, the three primary colors merging to form a continuous gradation, much better than the ink jet printing ink droplets effect by sublimation process gas. --------------------- Single terms of print quality, color sublimation printer that is digital camera best partner, therefore, this printer is also often referred to as digital color photo printer when printing on Portrait delicate texture of the skin, especially for requirements, but also has the characteristics of long-term preservation and difficult to fade. --------------------- 5 yellow, red, blue, and this is our daily said the three primary colors of any color can be made to reconcile the three primary colors, dye-sublimation printer is through the tri-color mix to achieve a variety of colors and color depth. --------------------- 6. However, sublimation printing process, the three colors are not printed at the same time, but each use a color, into a desired color of the composition of the three print requirements. It is also for this reason, the print media in the printing process, a total of need after the printer 3 times, so that the dye-sublimation printer printing process is relatively slow, but very high quality photo printing enough to compensate for this shortcoming. --------------------- 7 Some sublimation printers in three color, as well as an attached film process. Three color special material sublimation ribbon and attach to paper to form a protective film, the film can play oxidation discoloration, waterproof, anti-fingerprint and other role. This thing is an inkjet printer can not do. --------------------- Sublimation printer ribbon is a one-time use, the ribbon generally and the print paper with supporting Offering every roll of ribbon on the yellow, red, blue three colors for a group, each print a photo on volume one Group ribbon. --------------------- So although sublimation printer can also print in low resolution, but does not reduce printing costs, only slightly improve the printing speed, it is recommended that the total print at the highest resolution. ======================== [Advantages] --------------------- 1 save a long time] Using a dye-sublimation printer output images, the printer will be coated with protective film for the image, this coating function can be described dye-sublimation printer unique function. After coating the images, photos, not only has a waterproof, anti-oxidation characteristics preservation longer than traditional inkjet photo printer output. --------------------- 2 [portable] Sublimation printers are generally small volume, a lot of products on one hand can be picked up and used, and dye-sublimation printers can be separated from the computer to work independently, there are many products and even a built-in flash memory card reader and LCD display user-friendly, dye-sublimation printer alone with the access and use of digital equipment, so can the printer with the outdoor print or field work, but is also very convenient geographical between mobile use. --------------------- 3 [noise] Sublimation printer noise is very small, and fully capable of satisfying, whether it is brought out in the office or outdoor use, does not produce noise harassment. ======================== [Disadvantage] --------------------- 1 Print speed is slow] Sublimation printer print red, yellow, and blue primary cycle, every print one color, paper should walk in the path of printing a back and forth, so the completion of a print job needs to go three times paper, the film also need plus again. Therefore, the efficiency of the dye-sublimation printer with jet printing compared to much slower, three times the speed of traditional color PHYSICOCHEMICAL almost faster than dye-sublimation printers, and dye-sublimation printers can not reduce the print resolution to improve print speed. This way so that the dye-sublimation printer is not suitable often requires the use of continuous printing, to impede it can not achieve greater development in the commercial sector. --------------------- [Print format narrower] Currently, the most common sublimation printer only has a 4 × 6 inches (A6 format) output capability, just ordinary photo size jet printing A4 or A3 size dye-sublimation printer there are still a large gap between . Slightly large format sublimation printer, not only the machine itself is expensive, and the price is also very expensive supplies, and is not suitable for mass user selection. --------------------- 3. Use environment demanding] Sublimation printer is very sensitive to dust, dust from entering the print head or the ribbon, the print quality is very likely to have a serious impact, such as the formation of a long white thin line, causing the entire photo scrapped. In addition, dye-sublimation printers work also high temperature requirements, work continuously for a long time, due to poor heat dissipation may affect color accuracy. --------------------- 4 higher purchase costs and supplies] A common dye-sublimation printer about a thousand or so, which relative to the average home color inkjet printer as long as three, about four hundred yuan price, or your lot. In Secondly, currently sublimation printer consumables also slightly higher than PHYSICOCHEMICAL more, for example, the same print a 6-inch photo, the cost of using jet printing each photo is about 2.5 million, and dye-sublimation printing cost is 3 yuan (including printer depreciation, the cost of ink, ribbons and photos). However, due to the relatively large difference between jet printing consumables prices, the cost of some jet printing supplies even than dye-sublimation printers are more expensive, so the the sublimation consumables cost or acceptable. ======================== [Resolution] The print resolution is an important indicator of the measure of the printer print quality, which determines the printer to print images can fine performance, its level has an important influence on the output quality, print resolution is also decided, therefore, in a certain extent, The output quality of the printer. The higher the resolution, and can display the number of pixels reflected more, may exhibit more information and a better and clearer picture. Because of the technical characteristics of the dye-sublimation printer, print the same format pictures, a lower resolution than inkjet printers, but its print form continuous gradation of color printing effect, but they can be comparable to high-end inkjet photo printer, the picture color transition The smoothing nature is the main features of print. Because of the characteristics of the dye-sublimation printers are not suitable for printing text, tables, etc.. Print time is not a dye-sublimation printer-specific parameters. Laser, the printing speed of the inkjet printer is generally refers to the printer output paper pages per minute print units with PPM (Pages Per Minute). ======================== 【Note】 The way, but also to remind one: After printing, the printed image, the text will be left on the used ribbon latent image, if the print is confidential information, it is recommended to save the good ribbon, and destroyed after use. Printer resolution, also known as the output resolution refers to the horizontal and vertical direction in the printout per inch, capable of printing up to the number of points, usually dots / inch, dpi (dot per inch). The so-called maximum resolution refers to the maximum resolution of the printer is capable of printing, also said the ultimate resolution of the printout. Usually referred to printer resolution generally refers to the maximum resolution of the printer, sublimation printer resolution is generally at 300 × 300dpi. ======================== OTHER INFORMATION 1 users of laser or ink jet printer products, identification speed print speed as standard units of measurement. However, dye-sublimation printers print technology with laser or inkjet printer, usually per minute print less than one, so sublimation printer print speed in seconds, dye-sublimation printer print speed in about ninety seconds The first time a little longer, because of the need to preheat the heated print head. --------------------- Sublimation printer when printing red, yellow, blue three-color film by heat treatment followed by vaporized imprint in the special paper, because the heating device heating level can be divided into 128 or 256, so the result of The heat the Ascension of vaporization pigment concentration is also different color will correspond to the 128 or 256 consecutive Levels, which is the concept of color grading. The three primary colors for each color 128 or 256 can generate 2,097,000 color or 16,770,000 colors continuous gradation of color, 16.77 million colors, which have almost the limit of the human eye can distinguish color depth. The dye-sublimation printer more than 256 color levels. ======================== 【Article is excerpted from: Baidu Encyclopedia】 【Network reprint / Just reference】 【Translation is by Goolge】 |
