تعريف lithography في الإنجليزية الإنجليزية القاموس.
The process of printing a lithograph on a hard, flat surface; originally the printing surface was a flat piece of stone that was etched with acid to form a surface that would selectively transfer ink to the paper; the stone has now been replaced, in general, with a metal plate
> A planographic printing process where a drawing is made directly on a stone or other smooth matrix with greasy materials such as lithographic crayon The surface is dampened with water, which is repelled by the greasy areas The surface is then rolled with greasy printing ink which adheres only to the greasy areas and is itself repelled by the areas which have water The drawn image is then printed
a method of printing invented in the late 18th century, a drawing is made on a flat plate with a grease-based crayon and then washed off Ink is then applied and it adheres to the crayon but rinses clean from the rest of the plate Covering the plate with paper and pressing lightly to transfer the ink then make a print or lithograph
the act of making a lithographic print a method of planographic printing from a metal or stone surface
Lithography is a process based on the chemical principle that oil and water do not mix Images are drawn on limestone or metal plates with crayons and inks which contain wax or oil After treatment with gum arabic, the non-image areas become water-receptive The stone or plate is wet before each inking with a roller, so the oil-base ink will adhere only to the image areas Paper is pressed against the surface with a bar or roller press
A printing process using a smooth, flat, porous surface of stone on which the design is laid down with grease and water so that only certain parts will take the ink and print
A printing process, a branch of Planography, involving employment of stones or metal plates whose printing surfaces are partly water repellent and ink repellent The process is especially adapted to fine half tone color effects or smooth ink solids
Printing technique using a planographic process in which prints are pulled on a special press from a flat stone or metal surface that has been chemically sensitized so that ink sticks only to the design areas, and is repelled by the non-image areas Lithography was invented in 1798 in Solnhofen, Germany by Alois Senefelder The early history of lithography is dominated by great French artists such as Daumier and Delacroix, and later by Degas, Toulouse-Lautrec, Picasso, Braque and Miro
A lithograph transfers an image from a flat surface using the principle that oil and water do not mix The artist draws the image to be printed on a flat slab of limestone, metal, or plastic using a greasy crayon The negative areas are treated with water, so that when the ink is rolled over the slab it adheres only to the greasy areas and not the wet ones The artist positions the slab on the paper and manually presses it to produce a monochromatic image The process must be repeated for each color
A printmaking process in which a drawing is made on stone or metal with greasy materials The surface is prepared so that the image takes ink while the non-image areas repel it The print is made with a lithographic press top
Printing process whereby the image area is separated from the non-image area by means of chemical repulsion
A method of producing a print from a slab of stone on which an image has been drawn with a grease crayon or waxy liquid
The art of producing printed matter from a metal plate on which the design to be printed accepts printing ink and the other parts of the plate being ink repellent
One of the four major divisions of printmaking in which a drawing is made with a greasy substance on a stone (limestone, marble, onyx) or metal plate (aluminum or zinc) The surface is then treated chemically so that the image areas accept ink and the non-image areas, when dampened with water, repel ink Lithography is a planographic medium with impressions pulled from a perfectly flat surface, unlike intaglio and woodblock printing in which the surface is in relief
A printing process using a metal plate on which the image area is ink-receptive and the blank area is ink-repellent
The art or process of putting designs or writing, with a greasy material, on stone, and of producing printed impressions therefrom
{i} printing process in which impressions are taken from a stone that has been treated with an oily substance and then coated with ink
The process depends, in the main, upon the antipathy between grease and water, which prevents a printing ink containing oil from adhering to wetted parts of the stone not covered by the design
A printing process based on the antipathy of grease and water The printing elements used are limestone and aluminum or zinc plates, grained to varying degrees of roughness The image can be produced by photochemical and transfer processes, or be drawn using lithographic crayons and pencils, tusche, chalk, and various grease, lacquer, or synthetic materials The stone is then washed with a solution, thus chemically producing water-receptive non-printing areas and grease-receptive image areas The drawing grease is cleaned from the printing surface A roller bearing greasy printing ink is then rolled over the surface, with the ink adhering only to drawn grease-receptive image areas Finally, paper is laid on top of the stone or plate, which is passed through a lithography press for transfer Lithography is often described as a surface or planographic printing process in order to distinguish it from the relief and intaglio processes
A method of printing from a plane surface The printing image is ink-receptive; the non-printing areas are ink repellent
Lithography is a planographic printing process, which is chemical in principle, based on the antipathy of grease and water The printing elements used are grained limestone slabs and grained aluminum or zinc plates Image areas are created with lithographic crayons, pencils, rubbing ink, and tusche (ink) which all contain grease and wax The completed image is treated with an acidified gum arabic solutions, thus producing water-receptive non-printing areas and ink (grease) receptive image areas next to one another Before printing, the image areas are washed out with solvents, a printing base applied, and the gum film washed off with water During the inking process with a roller, the stone or plate is kept continuously damp When fully inked the paper is laid directly on the stone or plate and pressure is applied from a bar or roller on the press Other methods of producing lithographic images are transfer lithography, photolithography, and offset
Lithography is the printing process based on the theory that water and oil will not mix The lithographic printing process uses a planographic plate to control where the printed image will appear This plate is sensitized to be ink-receptive in the image areas and water-receptive in the non-image areas After the plate is placed on the printing press, ink is applied to the surface of the plate and stays in the image areas A miniscule amount of a watersolution is applied to and stays in the non-image areas of the plate defining where the ink is positioned to an accuracy of 1/1000 of an inch
Printing from a flat surface with a design area that is ink-receptive The area that is not to print is ink-repellent The process is based on the principle that an oil-based design surface will attract oily ink
Lithography is a method of printing in which a piece of stone or metal is specially treated so that ink sticks to some parts of it and not to others. + lithographic litho·graph·ic The book's 85 colour lithographic plates look staggeringly fresh and bold. a method of printing in which a pattern is cut into stone or metal so that ink sticks to some parts of it and not others (lithographie, from lithos + -graphia ). Printing process that makes use of the immiscibility of grease and water. Aloys Senefelder of Prague (1771-1834) exploited the properties of a stone with a calcium carbonate base and a fine, porous surface, and perfected his printing process in 1798. In Senefelder's process, the stone, with a design drawn on it with crayon or greasy ink, was wetted with water; after various etching and protecting steps, it was brushed with oily ink; it retained the ink only on the design. This inked surface was then printed either directly on paper, by a special press (as in most fine-art printmaking), or onto a rubber cylinder and thence onto paper (as in commercial printing). The method of preparing stones for hand printing, still the lithographic method preferred by artists, has hardly changed. Commercial lithographic printing on a modern rotary offset printing press can produce high-quality, finely detailed impressions at high speed, reproducing any material that can be photographed in the platemaking process. It now accounts for more than 40% of all printing, packaging, and publishing, more than twice the percentage produced by any other single printing process
Marks made on a prepared stone are printed by means of certain inks' varying affinity for oily and watery surfaces (very loosely speaking)
Also referred to as planography or surface printing, lithography operates on the principle that water and grease repel each other The image is created on a matrix of limestone, with a grease pencil, crayon, or liquid (tusche) The stone is washed with a solution of nitric acid and gum arabic, which affects the surface chemically so that the greased areas (the drawing) are etched onto the stone, but the non-greased/non-printing areas are unaffected When the stone is then dampened, and a grease-based ink rolled onto the surface, the ink will adhere only to the already greasy areas Paper is laid on the stone, subjected to a press, and the image on the stone is transferred to the paper
A surface printing process based on the mutual incompatibility of grease and water (derived from the Greek term lithos meaning stone and grapho, meaning to write ) A greasy crayon is used to draw the design on the surface of a porous stone More modern methods use disposable aluminum plates instead of the original limestone blocks The stone is then thoroughly wetted and an oil based ink rolled across its surface Where the greasy design has repelled the water, the ink will adhere Paper is then pressed onto the stone Each print in the edition usually requires re-wetting and re-inking the stone or plate
The process of printing that utilizes flat inked surfaces to create the printed images
A printing method in which the printing and non-printing areas exist on the same plane, as opposed to a bi-leveled reproduction
