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.
This technique keeps the paper dry and allows fully automated high-speed operation. It has mostly replaced traditional lithography for medium- and high-volume printing: since the 1960s, most books and magazines, especially when illustrated in colour, are printed with offset lithography from photographically created metal plates.
J.I. Biegeleisen and Max Arthur Cohn (a co-founder of the Society noted above), writing in 1942 about the origin and development of serigraphy, observed: "Specially noteworthy has been the work of the National Serigraph Society, New York, which has been the source of inspiration, clearing house, and temple of artists and print makers everywhere.
Screen printing may be adapted to printing on a variety of materials, from paper, cloth, and canvas to rubber, glass, and metal. Artists have used the technique to print on bottles, on slabs of granite, directly onto walls, and to reproduce images on textiles which would distort under pressure from printing presses.
Citing the pioneering efforts of artist Anthony Velonis, who initially spearheaded the use of the silk screen technique in the Poster Division of the W.P.A., for recognizing the possibilities of the medium, Warsager noted that the 'economy and ease of this process enabled the artist to employ sixteen to twenty colors to a print, whereas color ...
Intaglio (/ ɪ n ˈ t æ l i. oʊ,-ˈ t ɑː l i-/ in-TAL-ee-oh, - TAH-lee-; [1] Italian: [inˈtaʎʎo]) is the family of printing and printmaking techniques in which the image is incised into a surface and the incised line or sunken area holds the ink. [2]
Rather than printing multiple copies of a single image, only one impression may be produced, either by painting or making a collage on the block. Etching plates may also be inked in a way that is expressive and unique in the strict sense, in that the image cannot be reproduced exactly. [ 1 ]
Phototypesetting machines project characters onto film for offset printing. Prior to the advent of phototypesetting, mass-market typesetting typically employed hot metal typesetting – an improvement introduced in the late 19th century to the letterpress printing technique that offered greatly improved typesetting speed and efficiency compared to manual typesetting (where every sort had to be ...
