Paste paper used as a book covering, c. 1749. Paste paper is a type of surface design in which a colored, viscous media (generally starch paste) is applied directly to the surface of a paper sheet and modified with various tools and techniques to render an array of patterns and effects.
Three shapes overlaid with different screentone patterns. Screentone is a technique for applying textures and shades to drawings, used as an alternative to hatching.In the conventional process, patterns are transferred to paper from preprinted sheets. [1]
A watermark is an identifying image or pattern in paper that appears as various shades of lightness/darkness when viewed by transmitted light (or when viewed by reflected light, atop a dark background), caused by thickness or density variations in the paper. [1]
It can also introduce distortions and visual effects like moiré patterns. Especially when printed on newspaper, the halftone pattern becomes more visible due to the paper properties. By scanning and reprinting these images moiré patterns are emphasized. Thus, reconstructing them before reprinting is important to provide a reasonable quality.
One may use a transparency with text, designs, patterns, a stencil, or a completely opaque material shaped according to the desired area of burning/dodging. Many modern digital image editing programs have "dodge" and "burn" tools that mimic the effect on digital images.
Before the development of photography and of halftones, line art was the standard format for illustrations to be used in print publications, using black ink on white paper. Using either stippling or hatching , shades of gray could also be simulated.
Earlier RGBW filter pattern. Another 2007 U.S. patent filing, by Edward T. Chang, claims a sensor where "the color filter has a pattern comprising 2×2 blocks of pixels composed of one red, one blue, one green and one transparent pixel," in a configuration intended to include infrared sensitivity for higher overall sensitivity.
