Whiteprinting replaced the blueprint process for reproducing architectural and engineering drawings because the process was simpler and involved fewer toxic chemicals. A blue-line print is not permanent and will fade if exposed to light for weeks or months, but a drawing print that lasts only a few months is sufficient for many purposes.
Thermal printing (or direct thermal printing) is a digital printing process which produces a printed image by passing paper with a thermochromic coating, commonly known as thermal paper, over a print head consisting of tiny electrically heated elements. The coating turns black in the areas where it is heated, producing an image.
The salt print was the dominant paper-based photographic process for producing positive prints (from negatives) from 1839 until approximately 1860. Saint Michael's Church, Winterbourne, April 1859, salted-paper print, Department of Image Collections , National Gallery of Art Library, Washington, DC
In computing terminology, black-and-white is sometimes used to refer to a binary image consisting solely of pure black pixels and pure white ones; what would normally be called a black-and-white image, that is, an image containing shades of gray, is referred to in this context as grayscale. [2]
In graphic art film, also called lithographic film which is a special type of black and white film used for converting images into halftone images for offset printing, a developer containing methol-hydroquinone and sulfite stabilizers may be used. Exposed silver halide oxidizes the hydroquinone, which then oxidizes a nucleating agent in the ...
Digital cylinder printing is a method of reproducing black-and-white or full-color images and text onto cylindrical objects, typically promotional products, through use of digital imaging systems. The digital process is by definition faster than conventional screen printing , because it requires fewer production steps and less set-up time for ...
This printing technique is referred to as CMYK (the "K" stands for key, a traditional word for the black printing plate). Today's digital printing methods do not have the restriction of a single color space that traditional CMYK processes do. Many presses can print from files that were ripped with images using either RGB or CMYK modes.
