Pad printing (also called tampography) is a printing process that can transfer a 2-D image onto a 3-D object (e.g., a ceramic pottery).This is accomplished using an indirect offset printing process that involves an image being transferred from the cliché via a silicone pad onto a substrate.
Although the name "hecto-graph" implies production of 100 copies, in reality the gelatin process produced print runs of somewhere between 20 and 80 copies, depending upon the skill of the user and the quality of the original. At least eight different colors of hectographic ink were available at one time, but purple was the most popular because ...
Offset printing is a common printing technique in which the inked image is transferred (or "offset") from a plate to a rubber blanket and then to the printing surface. When used in combination with the lithographic process, which is based on the repulsion of oil and water, the offset technique employs a flat (planographic) image carrier.
The printing cylinders are usually made from copper plated steel, which is subsequently chromed, and may be produced by diamond engraving; etching, or laser ablation. Gravure printing is known for its ability to produce high-quality, high-resolution images with accurate color reproduction and using viscosity control equipment during production.
In printing, the doctor blade (from ductor blade) [1] removes the excess ink from the smooth non-engraved portions of the anilox roll and the land areas of the cell walls. [2] Doctor blades are also used in other printing and coating processes, such as flexo and pad printing for the same function.
Laser printing is an electrostatic digital printing process. It produces high-quality text and graphics (and moderate-quality photographs) by repeatedly passing a laser beam back and forth over a negatively charged cylinder called a "drum" to define a differentially charged image. [ 1 ]
