What is the principle of lithography?
Lithography generally involves the transfer of a pattern from a master into a pattern transfer layer, the resist, which is then used for subsequent pattern transfer onto a working surface, e.g., silicon. There are several different lithographic pattern techniques, of which photolithography is the most common.
What is the difference between a lithograph and a print?
Main Differences Between Lithograph and Print
- A lithograph can also be called a print. ...
- The lithograph is the artist’s original artwork; on the other hand, it is a copy of the original artwork.
- Lithography can be done on stone, metal, and blank paper. ...
- Original lithography has a signature of the artist, whereas print does not contain any artist’s signs.
What is a lithograph and how lithography came to be?
The word lithograph comes from the Greek lithos (stone) and graphein (to draw). A lithograph is a print made using the printing technique of lithography, which is a drawing on stone. Lithography uses a flat and heavy limestone polished to a very soft and flat surface to allow for an image or text to be drawn upon it for printing.
What are the steps of lithography?
A step-by-step guide to stone lithographyGraining the stone. Once a stone has been printed from for the last time, it is necessary to re-grain the stone to remove the greasy image and enable the stone to be re-used. ... Drawing on the stone. ... Processing the stone. ... Washing out and rolling up. ... Printing the stone.
What is the purpose of lithography process?
Lithography is the process of printing that uses the immiscibility of grease and water to create a high-quality print and can be used to print text or artwork onto paper or various other materials. The word lithography is derived from the Greek word lithos, meaning “stone” and graphein, meaning “to write.”
What is lithographic technique?
Lithography is a printing process that uses a flat stone or metal plate on which the image areas are worked using a greasy substance so that the ink will adhere to them by, while the non-image areas are made ink-repellent.
What is lithographic process surface?
The surface of a lithographic stone is a very seductive surface to draw on. It's responsive and it's also sculptural. Because the stone in and of itself is receptive to water, so if I dampen the stone it absorbs the water, and it's also receptive to grease, which means it will suck the grease down in.
What is an example of a lithograph?
The definition of lithography is a method of printing from a flat surface where unnecessary ink is turned away from the surface, generally by grease. An example of lithography is printing a message on a stone using grease to repel unwanted ink.
What is the difference between a print and a lithograph?
The difference between a lithograph and a print is that a lithograph is a hand made original copy whereas a print is normally a reproduction that is made via various printing methods.
What are the advantages of lithography?
The greatest benefit of litho printing is that it prints on a variety of surfaces and is not simply limited to paper. If a surface is smooth and practical, images can be printed on it using lithography.
Is lithography still used today?
High-volume lithography is currently used to produce posters, maps, books, newspapers, and packaging—just about any smooth, mass-produced item with print and graphics on it. Most books, indeed all types of high-volume text, are now printed using offset lithography.
Who invented lithography?
Aloys SenefelderDiscovered in Germany in 1798 by Aloys Senefelder in 1798, it wasn't until 1820 that lithography became commercially popular. Compared to earlier techniques such as engraving and etching, lithography was easier and more versatile.
How the lithographic process builds up an image?
In simple terms, your images or text are etched by a laser on to an aluminium plate which has a coating on it. This plate is then put on to the printing press which is made up of lots of rollers that the material goes through. The plate is inked up and transferred to a rubber blanket.

How are lithographic plates made?
Images on lithographic plates are traditionally created by a photographic process. The plate is often an aluminum plate grained by a chemical or electrolytic treatment to render the printing surface hydrophilic. The hydrophilic substrate is then coated with the photosensitive layer which works as an oleophilic layer.
What is one reason for the invention of lithography?
Instead of writing it once by hand over and over and over and over, Senefelder developed lithography for the purpose of writing that orchestral arrangement one time, so it could be reproduced, so that it could be sold to multiple orchestras throughout cities throughout all over Europe.
What are the advantages of lithography?
The greatest benefit of litho printing is that it prints on a variety of surfaces and is not simply limited to paper. If a surface is smooth and practical, images can be printed on it using lithography.
Which is among the benefits of lithography?
Advantages of litho printing Image quality: Litho printing provides excellent image quality at relatively low costs compared to other print methods like gravure which can cost up to 10 times more. Cost savings: Lithography provides exceptional value in the case of large volume printing.
What is one reason for the invention of lithography quizlet?
(2.3 printmaking) The lithographic process was devised in 1796 by a printer looking for an easier way to combine text and images on the same page.
How are lithographs made?
The earliest—though no longer the only—method of creating lithographs involved the use of a block of porous limestone. The method of preparing such stones for hand printing has remained substantially unchanged since Senefelder’s time. The materials and procedures of the 19th-century lithographer are duplicated in almost every respect by the contemporary hand printer. An image is drawn with tusche (a carbon pigment in liquid form) and litho crayon before the printing surface is fixed, moistened, and inked in preparation for printing. The printing itself is done on a press that exerts a sliding or scraping pressure. Because it undergoes virtually no wear in printing, a single stone can yield an almost unlimited number of copies, although in art printmaking only a specific number of prints are pulled, signed, and numbered before the stone is “canceled” (defaced). Techniques developed in the 20th century varied the process considerably, though many artists continue to prefer the time-honoured method.
What was the purpose of lithography?
After about 1825 many firms that utilized the lithographic process were established for producing a variety of commercial work and for distributing popular topical, historical, and religious subjects to a wide audience. The best known of these publishers was Currier & Ives of New York City.
What is the process of printing that makes use of the immiscibility of grease and water?
lithography, planographic printing process that makes use of the immiscibility of grease and water.
When did lithography become popular?
Some good early work was done in colour lithography (using coloured inks) by Godefroy Englemann in 1837 and Thomas S. Boys in 1839, but the method did not come into wide commercial use until 1860. It then became the most popular method of colour reproduction for the remainder of the 19th century. These commercial prints were made by preparing a separate stone by hand methods for each colour (tint) to be used and printing one colour in register over another. Sometimes as many as 30 stones were employed for a single subject.
Which printing process had undergone significant development?
A third printing process that had undergone significant development was lithography, neither relief nor intaglio printing but based on the principle that water and grease will not mix. In 1796 Aloys Senefelder of Prague investigated the properties of a stone with a…
How were commercial prints made?
These commercial prints were made by preparing a separate stone by hand methods for each colour (tint) to be used and printing one colour in register over another.
When were lithographs invented?
Colour lithographs, called chromolithographs or oleograph s, were developed in the second half of the 19th century. Although popular, they were of generally poor quality. In the hands of Henri de Toulouse-Lautrec, however, colour lithography in the 1890s reached new heights, and his example was enthusiastically followed by Paul Gauguin, Pierre Bonnard, and Édouard Vuillard. The subtle views of the River Thames that the American expatriate artist James McNeill Whistler rendered in the late 19th century in transfer lithography stand in marked contrast to the straightforward and robust lithographs commercially produced in the United States in the mid-19th century by the firm of Currier & Ives.
What is lithography in art?
Lithography, from the Greek for "stone printing," is an intricate printmaking process that revolves around grease and water resisting one another. An artist will draw with a greasy material on a lithographic stone, and then chemically treat the stone to etch the drawing into the stone, which can then be inked to produce many impressions on paper.
What is the surface of lithographic stone?
The surface of a lithographic stone is a very seductive surface to draw on. It's responsive and it's also sculptural. Because the stone in and of itself is receptive to water, so if I dampen the stone it absorbs the water, and it's also receptive to grease, which means it will suck the grease down in.
What material is used to draw on lithographic stone?
An artist will draw with a greasy material on a lithographic stone. Once we've established a drawing, or grease, on the stone, we chemically treat the stone with materials like gum arabic to establish the areas where water goes; rosin and talc, to help us through what we call an etch, or it's basically to establish the drawing down inside the stone.
What is the process of lithography?
Lithography is a planographic printmaking process in which a design is drawn onto a flat stone (or prepared metal plate, usually zinc or aluminum) and affixed by means of a chemical reaction.
How to make a multicolor lithograph?
In order to make a multicolor lithograph, additional stones or matrices must be used for each desired color. The same sheet of paper is run through the press repeatedly to add each color, and care must be taken to precisely register, or align, the stone each time.
How is ink applied to a stone?
Before the stone is ready for inking, it is dampened with water, which is absorbed only in the blank areas. Ink is then applied to the stone with a roller. The oil-based ink adheres to the greasy area of the image and is repelled by the damp parts of the stone. The dampening and inking of the stone is repeated until the entire image is thoroughly inked.
What does the impression on paper show when you press a stone?
Once the stone has been run through the press, the resulting impression on paper displays a reverse image of the original composition drawn onto the stone.
What is a flatbed press?
A flatbed press is equipped with a pressure bar. This bar, which usually approximates the size of the image, is lowered onto the tympan and the stone, and is dragged across the greased surface as it passes through the press. The bar guarantees a smooth and even application of pressure across the surface of the stone.
What is the wavelength of a lithography?
Exposure wavelengths used in optical lithography are from the UV and near UV portions of the electromagnetic spectrum. Lithographers often refer to monochromatic exposure systems as "i-line", "g-line", DUV etc. as opposed to specifying the actual wavelength emitted. Systems with broad spectrum lamps or "broadband" systems typically emit wavelengths that span roughly the 350nm to 450nm wavelength range (or some subset of this range).
What is the most common method of applying photoresist to a substrate surface?
Spin coating is the most common method for applying photoresist to a substrate surface. Other less common methods include spraying, roller coating, dip coating and extrusion coating.
How to prevent photoresist from delaminating?
To prevent complete or partial delamination of the photoresist film during pattern develop, wet etch or plating, substrate surfaces must be properly cleaned and dehydrated prior to coating. Trace residues, including surface moisture, will allow the developer, etchant, or plating solution to penetrate the photoresist/substrate interface and undercut the photoresist pattern.
