Technical Analysis of portable inkjet photo printer dye-sublimation PK – photo printer, printer-IT i

Article by jekky

Portable photo currently on the market Printer Features from a technical distinction between a inkjet and dye sublimation of two but both techniques have their advantages then choose the time what type of product is more suitable for yourself Now Xiao Bian will make an analysis of both technologies hoping to lift the doubts for you Digital Cameras The best partners therefore that Printer Also often referred to as color Digital Photo printers especially suitable for fine print on the portrait demands delicate skin texture but also not easy to fade with the characteristics of long term preservation Yellow red blue This is our daily said the three primary colors any other color can be reconciled by the three primary colors made dye sublimation printer that is achieved through the tri color mix of a variety of colors and color depth However dye sublimation printing process the three kinds of color printing is not the same time but every time you use a color by three times to form the required color printing requirements Is precisely for this reason the print media in the printing process a total of 3 times to go through the printer dye sublimation printer makes printing process is relatively slow but high enough to make up for the photo print quality defects Some sublimation printers in three color after the process and a membrane attached That the three colors on the re use of special materials on the sublimation ribbon and attach to paper to form a protective film the film can play up oxidation discoloration Drainage put the role of fingerprints This is ink jet printer can not do Dye sublimation printer ribbon is a one time use and printing paper ribbon with matching general sale each volume on the yellow ribbon red blue three colors as a group each print a photo a team color on paper band So although sublimation printer can print in low resolution but does not reduce printing costs can only slightly improve the printing speed the proposed total to the highest resolution print Way also to remind one print after print of the image the text will be used ribbon latent image on the left if the print content is confidential information the proposed preservation good ribbon and destroyed after use Printer resolution also known as the output resolution refers to the printed output in both horizontal and vertical directions can be printed per inch maximum number of points usually a quot point inch quot or dpi dotperinch said The so called maximum resolution refers to the maximum resolution the printer can print that is what limits the resolution printed output Usually referred to the printer resolution generally refers to the maximum printer resolution the resolution of the present dye sublimation printers are usually around in the 300 300dpi Print resolution is a measure of printer quality of key indicators which determines the printer can print images the performance of sophistication and its level of output quality has an important influence to some extent therefore the decision also print resolution the printer 39 s output quality The higher the resolution which reflected the number of pixels to display the more can present more information and better and more clear image However since dye sublimation printer 39 s technical characteristics while printing the same picture format resolution less than the ink jet printers but the print is a continuous gradation of the print form but high end inkjet photo printers can be comparable picture color smooth transition is of course the main features of its print Precisely because of the characteristics of dye sublimation printers are not suitable for printing text tables and so on Dye sublimation printer printing time is not a specific parameter Laser inkjet printers printer print speed usually refers to the output of paper per minute number of pages printed the unit with the PPM PagesPerMinute said All printer manufacturer currently available for users of laser or inkjet printer products logo to print faster speed as a standard unit of measurement But the dye sublimation printer for printing using laser or inkjet printer technologies and different generally less than a minute to print so the speed dye sublimation printer in seconds expressed as a general dye sublimation printer prints at speeds around 90 wonderful debut little longer because of the need warm heated print head Dye sublimation printer will print in red yellow blue three color film vaporization followed by heat treatment after stamping on a dedicated photo paper because the level of the current heating heater parts can be divided into 128 or 256 level so because of heating vapor different pigment concentrations of vaporization resulting in color will correspond to a 128 or 256 of the continuous color scale which is the concept of the color grade Three colors per color 128 or 256 can generate a total of 2 097 million color or colors of the continuous gradation 16 770 000 16 770 000 color that is almost the color of the human eye can distinguish between the depth limits Current dye sublimation printer with 256 multi color grade
