John C. Moss
John Calvin Moss (January 5, 1838 – April 8, 1892) was an American inventor credited with developing the first practicable photoengraving, photo-engraving process in 1863. His work, and that of others such as William Leggo in Canada led to a revolution in printing and eventually to the mass marketing around the world of newspapers and magazines and books which combined photographs with traditional text. Life John Moss was born in Bentleyville, Pennsylvania on January 5, 1838. At age 17 he became an apprentice to a Philadelphia printer. At 19, he married Mary A. Bryant who would become his partner in developing a workable photo-engraving method. Moss attributed much of his success to Mary's help.For a detailed personal account of John C. Moss and his wife Mary see: In 1858 Moss became a photographer and began experiments in photographic chemistry. Being both a practical photographer and a professional printer helped put him in the forefront of inventors who were striving to perf ...

Wood Engraving
Wood engraving is a printmaking technique, in which an artist works an image or ''matrix'' of images into a block of wood. Functionally a variety of woodcut, it uses relief printing, where the artist applies ink to the face of the block and prints using relatively low pressure. By contrast, ordinary engraving, like etching, uses a metal plate for the matrix, and is printed by the intaglio method, where the ink fills the ''valleys'', the removed areas. As a result, wood engravings deteriorate less quickly than copper-plate engravings, and have a distinctive white-on-black character. Thomas Bewick developed the wood engraving technique in Great Britain at the end of the 18th century. His work differed from earlier woodcuts in two key ways. First, rather than using woodcarving tools such as knives, Bewick used an engraver's burin (graver). With this, he could create thin delicate lines, often creating large dark areas in the composition. Second, wood engraving traditionally use ...

Coffee Table Book
A coffee table book, also known as a cocktail table book, is an oversized, usually hard-covered book whose purpose is for display on a table intended for use in an area in which one entertains guests and from which it can serve to inspire conversation or pass the time. Subject matter is predominantly non-fiction and pictorial (a photo-book). Pages consist mainly of photographs and illustrations, accompanied by captions and small blocks of text, as opposed to long prose. Since they are aimed at anyone who might pick up the book for a light read, the analysis inside is often more basic and with less jargon than other books on the subject. Because of this, the term "coffee table book" can be used pejoratively to indicate a superficial approach to the subject.. In the field of mathematics, a coffee table book is usually a notebook containing a number of mathematical problems and theorems contributed by a community meeting in a particular place, or connected by a common scientific inte ...

Engraving
Engraving is the practice of incising a design onto a hard, usually flat surface by cutting grooves into it with a Burin (engraving), burin. The result may be a decorated object in itself, as when silver, gold, steel, or Glass engraving, glass are engraved, or may provide an Intaglio (printmaking), intaglio printing plate, of copper or another metal, for printing images on paper as prints or illustrations; these images are also called "engravings". Engraving is one of the oldest and most important techniques in printmaking. Wood engraving is a form of relief printing and is not covered in this article, same with rock engravings like petroglyphs. Engraving was a historically important method of producing images on paper in artistic printmaking, in mapmaking, and also for commercial reproductions and illustrations for books and magazines. It has long been replaced by various photographic processes in its commercial applications and, partly because of the difficulty of learning th ...

Half-tone
Halftone is the reprographic technique that simulates continuous-tone imagery through the use of dots, varying either in size or in spacing, thus generating a gradient-like effect.Campbell, Alastair. The Designer's Lexicon. ©2000 Chronicle, San Francisco. "Halftone" can also be used to refer specifically to the image that is produced by this process. Where continuous-tone imagery contains an infinite range of colors or greys, the halftone process reduces visual reproductions to an image that is printed with only one color of ink, in dots of differing size (pulse-width modulation) or spacing (frequency modulation) or both. This reproduction relies on a basic optical illusion: when the halftone dots are small, the human eye interprets the patterned areas as if they were smooth tones. At a microscopic level, developed black-and-white photographic film also consists of only two colors, and not an infinite range of continuous tones. For details, see film grain. Just as color phot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
