Professionally produced inkjet prints are much more expensive on a per-print basis than the four-color offset lithography process traditionally used for such reproductions. A large-format inkjet print can cost more than ten times that of a four-color offset litho print of the same image in a run of 1,000, not including scanning and color ...
This technique produces blue lines on a white background. The drawings are also called blue-lines or bluelines. [12] [13] Other comparable dye-based prints were known as blacklines. Diazo prints remained in use until they were replaced by xerographic print processes. Xerography is standard copy machine technology using toner on copy paper.

Hence, blueline drawings that are used as engineering working copy prints have to be protected when not in use by storing them in flat files in the dark. Incandescent lighting was often used in areas where blueline engineering prints needed to be posted on a wall for long periods to hinder rapid fading.
Color printing can also involve as few as one color ink or color inks which are not the primary colors. Using a limited number of color inks, or color inks in addition to the primary colors, is referred to as "spot color" printing. Generally, spot-color inks are formulations that are designed to print alone, rather than to blend with other inks ...
The stone is wetted, with water staying only on the surface not covered in grease-based residue of the drawing; the stone is then 'rolled up', meaning oil ink is applied with a roller covering the entire surface; since water repels the oil in the ink, the ink adheres only to the greasy parts, perfectly inking the image.
The Ben Day process is a printing and photoengraving technique for producing areas of gray or (with four-color printing) various colors by using fine patterns of ink on the paper. It was developed in 1879 [ 1 ] by illustrator and printer Benjamin Henry Day Jr. (son of 19th-century publisher Benjamin Henry Day ). [ 2 ]
A pencil drawing can have many shades of grey depending on the hardness of the graphite and the pressure applied by the artist, but an ink line generally can be only solid black. Accordingly, the inker has to translate pencil shading into patterns of ink, for example by using closely spaced parallel lines, feathering, or cross-hatching. The ...
