INKJET PRINTER
An inkjet printer is a type of non-impact printer. The working principle of this printer is that it ejects small drops of ink through small ink nozzles onto the paper by applying a resistive heating effect. It consists of a print cartridge having a set of ink nozzles that are heated using a heating resistor. This process of resistive heating takes very little time (i.e., up to microseconds). Due to the healing process, the ink cartridge (i.e., print head) gets expanded and ink droplets are ejected out through the nozzles onto the paper.
These ink droplets draw small ink dots in a particular sequence on the paper, and the combination of these ink dots results in the required character or image. The ink droplets are ejected by moving the cartridge at the specified positions at the same time the roller rolls. the paper to print the next line. An inkjet printer of high resolution is capable of printing 2400 dots per inch (dpi).
It can print images and characters/text irrespective of its size and shape. It can generate monochrome as well as color output based on the cartridges used. In order to produce a colored print, four different cartridges having different colors are such as Cyan (C), Magenta (M), Yellow (Y), and Black (K) is used.
Besides these colors, the other colors can be produced by taking suitable combinations of the colors CMYK. It can print pages in the range of 5 – 8 in one minute.
Ink formulations
The earliest regard to an eternal inkjet ink (CIJ) in 1971 patent US3596285A states ” the popular ink is characterized by the body and physical phenomenon characteristics specified the liquid can be maintained over the span thereunder force with that it’s occupancy bridge or stream.
Solvent inks
The main Of ingredients of these inks are volatile organic compounds (VOCs), organic chemical compounds that have high vapor pressures. The Color is achieved with pigments rather than dyes for excellent fade resistance. The main advantage of solvent inks is that they are comparatively inexpensive and enable printing on flexible, uncoated vinyl substrates, which are used to produce vehicle graphics, billboards, banners, and adhesive decals.
Professional inkjet photo printers
Inkjet printers for skilled pic printing in twelve totally different inks:
- Canon Inkjet printer : pic magenta, photo cyan, yellow, magenta, cyan, red, pic black, matte black, grey, and either blue, photo grey, and one vividness optimizer for black density and uniform smoothness, or lightweight gray, dark grey, and one vividness optimizer, or green, blue, and pic gray. four pl thermals.
- Epson Inkjet printer : (10 colors to 12): vivid magenta, yellow, cyan, orange, green, vivid light-weight magenta, light cyan, lightweight black, matte black or pic black, and AN irreversible alternative of either lightweight gray or violet (V not for photo). 3.5 pl piezo variable.
- HP Inkjet printer : magenta, yellow, red, green, blue, lightweight magenta, light cyan, grey, light grey, matte black, pic black, and one gloss attention four pl thermal.
They all will print a picture of thirty-six megapixels on A3 borderless pic paper with 444 PPI.
