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.
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 ...
In intaglio printing, the lines to be printed are cut into a metal (e.g. copper) plate by means either of a cutting tool called a burin, held in the hand – in which case the process is called engraving; or through the corrosive action of acid – in which case the process is known as etching. [6] [7]
Vitreography was initially conceived of as an intaglio process, in which line and tone are carved, engraved or etched into the glass plate’s surface. Printing an intaglio plate involves forcing ink into the grooves and pits, and then wiping the plate’s surface with tarlatan [15] to remove excess ink.
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).
A two-handled composition hand roller, for use in manually inking type. Before its invention, most inking of printing presses was done by manually pounding the type with ink balls, specially treated leather balls stuffed with wool. The difficulty and time involved in making and using ink balls led to various attempts to use cylinders, which ...
Printmaking is the making of a work of art by transferring ink from the surface upon which the work was originally drawn or otherwise composed to another surface. The main article for this category is Printmaking .
