		In intaglio printing, such as the etching and the steel engraving, the design to be printed is lower than the surface of the plate, which is wiped clean before each impression, leaving the incised design filled with ink, which the paper receives.
		In gravure intaglio printing, tone is produced by varying the thickness of the ink of the printing surface through depressions of varying depth; minute points constitute the clean surface that keeps the paper from being pressed into the depressions.
		Printing in colors is sometimes done, as excellently in Japan, by applying inks of different colors by hand to the printing surface, but usually a separate printing surface is used for each ink.

	Planographic printing plate for dry printing - Patent 4170687
		Planographic printing plates for use without fountain solution, and especially suitable for imaging with an electrophotographic toner, have a surface containing a fluorinated polyurethane.
		A planographic printing plate comprising a support sheet having an ink-repellent coating containing 0.5 to 15%, by weight of the said coating, of a fluorinated polyurethane obtained by reaction of a fluorinated polyol and a non-fluorinated polyol with a polyisocyanate, and the balance to 100% of a non-fluorinated film-forming synthetic resinous material.
		In conventional planographic printing (lithography), the image on the printing plate is not raised, or only very slightly raised, above the surrounding surface of the plate, and in use the image, which is oleophilic, attracts the greasy printing ink, while the mon-image areas, which are hydrophilic, repel the ink.

	Dampening of paper. Beguin.
		In the past high-pressure printing was almost always used since the paper was quite stiff and showed the lines left by the wire cloth and the felts.
		Dampening allows the artist to avoid a high printing pressure which is always bad for engraved lines since pressure tends to clog the lines and crush the grained parts of the plate.
		Industrial intaglio printing is always done on dry paper which is the reason for which the lines of such plates must be particularly precise.

	Printing Process Descriptions: Environment and Printing: The Printers' National Environmental Assistance Center: PNEAC: ...
		While most printing facilities utilize primarily one process or type of printing press, it is not uncommon to see multiple processes or types of printing presses at a printing facility.
		The five major printing processes are distinguished by the method of image transfer and by the general type of image carrier employed.
		In direct printing the image is transferred directly from the image carrier to the substrate, examples of direct printing are gravure, flexography, screen printing and letterpress printing processes.

	Directly imageable planographic printing plate precursor and a method of producing planographic plates - US Patent ... (Site not responding. Last check: 2007-10-11)
		A directly imageable planographic printing plate precursor according to claim 1 wherein the metal-containing organic compound is of at least one type selected from the group consisting of metal diketenates, metal alkoxides, alkyl metals and carboxylic acid metal salts.
		When a printing plate precursor of the present invention is subjected to laser irradiation, heat is generated due to the action of the light-to-heat conversion material in the heat sensitive layer and, as a result of this heat, the metal-containing organic compound gives rise to reaction.
		Of these, for the purposes of processing the printing plate precursor of the present invention, a semiconductor laser of emission wavelength region in the vicinity of the near infrared region is preferred, with the use of a high output semiconductor laser being particularly preferred.

	013 An Introduction to Graphic Communications Processes
		Planographic printing can be defined as reproduction methods in which there is little perceptible difference between the height of the printing and non-printing areas of the printing plate.
		The term photogravure indicates that photographic processes were used in preparation of the printing plate, and rotogravure is used to denote that the press used for printing is a rotary press.
		The point of concern for the printing industry is the uncertainty about whether this new technology will mean less business for printers, or merely that the expanded capability will allow offices to generate their internal communications with greater aesthetic appeal, eventually creating a greater demand for high quality printing.

		The acceptance of ink by the printing areas or repulsion by the non-image areas of the printing form has remained to this day the principle of planographic printing.
		The technical breakthrough in planographic printing cannot, however, be attributed purely to the fact that the printing form can be produced simply and economically.
		With direct printing the printing form prints the substrate directly, while with indirect printing, the printing form first offsets the ink to rubber (hence the term "offset") and it is this rubber that then transfers the ink onto the substrate.

		The essential properties of the printing ink itself are determined by the mixture of several varnishes with dry pigments in certain ratios.
		Intaglio printing requires a supple ink and a pigment which is somewhat coarser than the pigment used for planographic and relief printing ink.
		This prints as a plate tone, visible as a faint, greyish hue on the impression and typical for an etching.

	Cycleback: Examination of Prints
		A relief print is made by cutting away part of the surface of the printing plate, adding ink to the raised surface that is left and pressing the plate surface to the paper.
		Planographic printing involves a flat plate with the ink lying on the surface.
		This usually means that the artist uses her hands and hand held tools (such as chisels or brushes) to make the design directly onto the printing plate.

	OSHA Assistance for the Printing Industry - Industry Segments
		The printing industry can be separated into four main segments and each must comply with all of the general industry standards (29 CFR 1910).
		Lithography is a planographic printing system where the image and non-image areas are chemically differentiated with the image area being oil receptive and non-image area water receptive.
		Screen printing is a printing process in which printing ink, coating, or adhesive material is passed through a taut web or fabric to which a refined form of stencil has been applied.

	\| 1. Introduction \|
		In printing, ink is transferred to paper from another material, usually a metal plate or a wooden block.
		In stencil printing (silkscreen) there is a hole cut in the matrix and ink is pushed through it.
		In planographic printing (lithography) the matrix is flat, and the printing part is treated to hold ink, the other parts to repel it.

	PRINTMAKING
		The unique beauty of this type of printing lies in its capacity to allow ink films of different thickness to be deposited on the paper at the same time.
		Though the prints in an edition all look the same, they are not copies of one another any more than a twin is a copy of his brother.
		In a description of a print's media, the word "drypoint" is usually used alone, but may also be expressed as "drypoint engraving." It should not be called "drypoint etching," because this implies acid was used and acid is never used in making a drypoint print.

	Planographic Category
		Only one print can be made in the edition therefore the name "Mono" print is given to it.
		The print is made first onto another blanket (offset) so the image when printed won't turn out backward.
		The plates are created by making a negative of the image that needs to be printed and then a plate is sensitized in a plate burner that sensitizes the areas that need to print.
