Viscosity printing is a multi-color printmaking technique that incorporates principles of relief printing and intaglio printing. It was pioneered by Stanley William Hayter . The process uses the principle of viscosity to print multiple colors of ink from a single plate, rather than relying upon multiple plates for color separation .
The intaglio printmaking techniques all print images from ink held in the lines or other recesses made by the artist in the printing plate. For each impression, ink is spread over the whole plate, worked well in, and then the flat surface is normally wiped carefully clean to remove all ink except that in the recesses, using a form of squeegee.
The main types of flexographic ink are water based, [2] solvent and UV curable. [3] The printing surface (substrate type) dictates what ink type it is advisable to use.Each type of ink has its advantages and disadvantages, therefore the type of ink used in printing is determined by factors such as price, speed, and the use of the packaging (food, cleaning, or shopping bags).
The ink is controlled in the flexographic printing process by the ink system. The ink system contains an ink pump, anilox roll and either a fountain roll system or doctor blade system. The fountain roll or two-roll system has one roll spinning in an ink pan pressed against the anilox roll to transfer a layer of ink to then be applied to the ...
Reduction printing is a name used to describe the process of using one block to print several layers of color on one print. Both woodcuts and linocuts can employ reduction printing. This usually involves cutting a small amount of the block away, and then printing the block many times over on different sheets before washing the block, cutting ...
Using stencils to apply the glue and sprinkling different amounts of carborundum through the different stencils. To print a carborundum print, the surface is covered in ink, and then the surface is wiped clean with tarlatan cloth or newspaper, leaving ink only in the texture of the screen or carborundum. A damp piece of paper is placed on top ...
Dot matrix printers are a type of impact printer that prints using a fixed number of pins or wires [2] [3] and typically use a print head that moves back and forth or in an up-and-down motion on the page and prints by impact, striking an ink-soaked cloth ribbon against the paper.
This is a fairly rare example of a print entirely in aquatint. [5] In intaglio printmaking techniques such as engraving and etching, the artist makes marks into the surface of the plate (in the case of aquatint, a copper or zinc plate) that are capable of holding ink. The plate is inked all over then wiped clean to leave ink only in the marks.
