Ink requirement is defined as the amount of ink needed to print a unit area with a standard Solid Ink Density. For newsprint, the ISO 12647-3 specification is C 0.90, M 0.90, Y 0.90 and K 1.10, Status E, D50, 2o, density minus paper with polarization filter. Ink requirement is measured as g/m2 (grams of ink required to print 1 m2 of paper)
Offset printing is a common printing technique in which the inked image is transferred (or "offset") from a plate to a rubber blanket and then to the printing surface. When used in combination with the lithographic process, which is based on the repulsion of oil and water , the offset technique employs a flat ( planographic ) image carrier.
Manufacturers of printers or devices that use colour ink jet technology are meant to abide by this standard when testing for, and labeling the estimated yields of their products. The testing focused on sampling yields generated from typical business consumer printing applications. The judgment of total yield was defined by fade, marked by a ...
Inkjet printing is a type of computer printing that recreates a digital image by propelling droplets of ink onto paper and plastic substrates. [ 1] Inkjet printers were the most commonly used type of printer in 2008, [ 2] and range from small inexpensive consumer models to expensive professional machines.
Dot matrix printing. Dot matrix printing, [ 1] sometimes called impact matrix printing, is a computer printing process in which ink is applied to a surface using a relatively low-resolution dot matrix for layout. Dot matrix printers are a type of impact printer that prints using a fixed number of pins or wires [ 2][ 3] and typically use a print ...
In a typical drum printer design, a fixed font character set is engraved onto the periphery of a number of print wheels, the number matching the number of columns (letters in a line) the printer can print. The wheels, joined to form a large drum (cylinder), spin at high speed. Paper and an inked ribbon are stepped (moved) past the print position.
The amount of bleeding is affected by numerous factors, including the paper type, [3] paper's characteristics of ink absorption and its capillary action, [4] ink type and properties (speed of ink drying), printing technology (i.e. nozzle design and spacing with ink jet printers). Color bleeding in newspaper print.
Blue Wool Scale. The Blue Wool Scale measures and calibrates the permanence of colouring dyes. Traditionally this test was developed for the textiles industry but it has now been adopted by the printing industry as measure of lightfastness of ink colourants. [ 1][ 2] The American Association of Textile Chemists and Colorists pioneered the work ...
