Paper test. Paper and ink testing Tests for paper and ink interaction. A variety of tests are used to determine ink and paper and paperboard quality, and to measure their interactions. They are necessary to balance print quality, cost, and wear on the press. Some of the important paper and ink tests are listed here:
Press proof is a test print of the data directly on a printing press. This can be the press for the production run or a comparable press (using the same print technology) prepared especially for proof purposes. Short runs of 50 or 100 copies can be produced more cost-effectively than with other color proof processes.
Screen printing is a printing technique where a mesh is used to transfer ink (or dye) onto a substrate, except in areas made impermeable to the ink by a blocking stencil.A blade or squeegee is moved across the screen in a "flood stroke" to fill the open mesh apertures with ink, and a reverse stroke then causes the screen to touch the substrate momentarily along a line of contact.
Rotogravure (or gravure for short) is a type of intaglio printing process, which involves engraving the image onto an image carrier. In gravure printing, the image is engraved onto a cylinder because, like offset printing and flexography, it uses a rotary printing press. Once a staple of newspaper photo features, the rotogravure process is ...
t. e. 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.
Inkjet printing is a type of computer printing that recreates a digital image by propelling droplets of ink onto paper and plastic substrates. [1] Inkjet printers were the most commonly used type of printer in 2008, [2] and range from small inexpensive consumer models to expensive professional machines. By 2019, laser printers outsold inkjet ...

The printing press check is a step in the printing process. It takes place after a printing press is set up but before the print run is underway. Herzliya Airport (Israel) Runway location and Traffic Pattern chart (left) was erroneously printed as a result of "black layer" 180° misplacement. The corrected chart is on the right.
