Zink (stylised as ZINK, a portmanteau of zero and ink) is a full-color printing technology [1] for digital devices that does not require ink cartridges and prints in a single pass. [ 2 ] The printing technology and its thermal paper are developed by Zink Holdings LLC, a U.S. company, with offices in Edison, New Jersey , and Billerica ...
While the term may include ordinary printing with only two colors — "ink" and "no ink" — it usually implies the ability to produce several intermediate colors between those two extremes. In contrast with color printing, monochrome printing needs only a single ink and may require only a single pass of the paper through the printing press.
The advantages of waterless printing include the following: Higher screen rulings, resulting in better image definition, increased print contrast, and the elimination of rosette patterns. Wider color range than conventional offset plates. Higher ink densities with better ink holdout on any paper. More consistency of color during the run.
Carbonless copy paper has micro-encapsulated dye or ink on the back side of the top sheet, and a clay coating on the front side of the bottom sheet. When pressure is applied (from writing or impact printing), the dye capsules rupture and react with the clay to duplicate the markings made to the top sheet.
There are many techniques used in monoprinting, including collagraph, collage, hand-painted additions, and a form of tracing by which thick ink is laid down on a table, paper is placed on the ink, and the back of the paper is drawn on, transferring the ink to the paper. Monoprints can also be made by altering the type, color, and viscosity of ...
The paper is removed, and the ink has been transferred from the plate to the paper. Micro-topography of an ordinary French post stamp (detail) showing the thickness of ink obtained by intaglio. The words la Poste appeared in white on red background and hence corresponds to areas with a lack of ink.
The surface is covered with ink by rolling over the surface with an ink-covered roller , leaving ink upon the flat surface but not in the non-printing areas. Multiple colours can be printed by keying the paper to a frame around the woodblocks (using a different block for each colour).
In printing, set-off is the term given to the unwanted transfer of ink from one printed sheet to another. The problem can occur with most types of printing, and is avoided by the use of slipsheets between copies (so any ink transfer occurs onto discardable paper) or anti-set-off spray powder.
