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 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.
The Print Gocco process was a variant of screen printing; Print Gocco housed both the screen-making and screen-printing elements within one compact footprint with a hinged plastic frame. The materials included proprietary blank screens, consisting of thin layer of thermoplastic bonded to a mesh, held in a cardboard frame and covered with ...
Ludlow metal typesetting machine in Gutenberg Museum in Fribourg, Switzerland. A Ludlow Typograph is a hot metal typesetting system used in letterpress printing. The device casts bars, or slugs of type, out of type metal primarily consisting of lead. These slugs are used for the actual printing, and then are melted down and recycled on the spot.
Letterpress printing is a technique of relief printing for producing many copies by repeated direct impression of an inked, raised surface against individual sheets of paper or a continuous roll of paper. [1] A worker composes and locks movable type into the "bed" or "chase" of a press, inks it, and presses paper against it to transfer the ink ...
Woodblock printing had been known in China for centuries. It was innovations in type casting that made for Gutenberg's breakthrough of commercially printing. [1] Although using matrices was a technique known well before his time, Johannes Gutenberg adapted their use to a conveniently adjustable hand mould, enabling one to easily and accurately cast identical multiple instances of any character.
Typesetting is the composition of text for publication, display, or distribution by means of arranging physical type (or sort) in mechanical systems or glyphs in digital systems representing characters (letters and other symbols). [1] Stored types are retrieved and ordered according to a language's orthography for visual display.
Yellow dots on white paper, produced by color laser printer (enlarged, dot diameter about 0.1 mm) Printer tracking dots, also known as printer steganography, DocuColor tracking dots, yellow dots, secret dots, or a machine identification code (MIC), is a digital watermark which many color laser printers and copiers produce on every printed page that identifies the specific device that was used ...
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. It is believed that the name derives from the ...
