Inkjet printers are a type of computer printer that operates by propelling tiny droplets of liquid ink onto paper. They are
the most common type of computer printer for the general consumer due to their low cost, high quality of output, capability of printing in vivid color, and ease of use.
The emerging Ink jet material deposition market uses ink jet technologies, typically piezoelectric ink jet, to deposit materials on substrates..

stay on the surface and rapid dispersement of the carrier.
Desktop inkjet printers, as used in offices or at home, all use aqueous inks based on a mixture of water, glycol and dyes or
pigments. These inks are inexpensive to manufacture, but are difficult to control on the surface of media and therefore
often require specially coated media. Aqueous inks are mainly used in printers with disposable, so-called thermal inkjet
heads, as these heads require water in order to perform.
In professional wide format printers, a much wider range of inks is used, most of which require piezo inkjet heads:
Solvent inks: the main ingredient of these inks are VOCs. The main advantage of these inks is that they are very inexpensive
and also enable printing on uncoated vinyl substrates, which are used to produce vehicle graphics, billboards and banners.
UV-curable inks: these inks consist mainly of acrylic monomers with an initiator package. After printing, the ink is cured
by exposure to strong UV-light. The advantage of UV-curable inks is that they "dry" as soon as they are cured, they can be
applied to a wide range of uncoated substrates and produce a very robust image. Disadvantages are that they are more
expensive, require expensive curing modules in the printer and the cured ink has a significant volume and so gives a slight
relief on the surface.
Dye sublimation inks: these inks contain special sublimation dyes and are used to print directly or indirectly on to fabrics
which consist of a high percentage of polyester fibres. A heating step causes the dyes to sublimate into the fibers and
create an image with strong color and good durability. |
