    en.wikipedia.org/wiki/Waterless_printing

    Cooperative efforts from press, ink and paper manufacturers helped to support the product, and the overall market acceptance was very good. The first North American demonstration of the waterless process was at Print '80, and with the introduction of the negative (TAN) type plate in 1982 this market could be seriously pursued.

  5. Anti-set-off spray powder - Wikipedia

    en.wikipedia.org/wiki/Anti-set-off_spray_powder

    The diameter of the powder used is relative to the density (g/m 2) of the stock (paper or board) being printed. For 150 g/m 2 paper the ideal anti-set-off spray powder would be 15 μm in diameter, for 200 g/m 2 20 μm, through to 70 μm for heavy board (700 g/m 2). Most manufactures of spray powder offer both coated and uncoated powders.

  6. Trap (printing) - Wikipedia

    en.wikipedia.org/wiki/Trap_(printing)

    Thinner traps are less visible. Therefore, the trap width is set to a strict minimum, dictated by the maximum amount of misregistration of the entire workflow up to the press. When printing at 150 lpi, traps are usually between 1/150 and 1/300 inch (0.48 pt and 0.24 pt, 0.16 mm and 0.08 mm). These values are usually multiplied by 1.5 or 2 when ...

  7. Thermal-transfer printing - Wikipedia

    en.wikipedia.org/wiki/Thermal-transfer_printing

    Thermal-transfer printing is done by melting wax within the print heads of a specialized printer. The thermal-transfer print process utilises three main components: a non-movable print head, a carbon ribbon (the ink) and a substrate to be printed, which would typically be paper, synthetics, card or textile materials.

  9. Solid ink - Wikipedia

    en.wikipedia.org/wiki/Solid_ink

    Solid ink technology utilizes solid ink sticks, crayons, pearls or granular solid material instead of the fluid ink or toner powder usually used in printers. Some types of solid ink printers use small spheres or pucks of solid ink, which are stored in a hopper before being transferred to the printing head by a worm gear or melted as needed.
