Yellow dots on white paper, produced by color laser printer (enlarged, dot diameter about 0.1 mm) Printer tracking dots, also known as printer steganography, DocuColor tracking dots, yellow dots, secret dots, or a machine identification code (MIC), is a digital watermark which many color laser printers and photocopiers produce on every printed page that identifies the specific device that was ...
[35] [36] The brush size, [37] which is a number between 0 (small space between teeth) and 8 (large space), indicates the passage hole diameter. This corresponds to the space between two teeth that is just sufficient for the brush to go through without bending the wire. The color of the brushes differs between producers.
A common way of setting the bristles, brush filaments, in the brush is the staple or anchor set brush in which the filament is forced with a staple by the middle into a hole with a special driver and held there by the pressure against all of the walls of the hole and the portions of the staple nailed to the bottom of the hole.
Paper marbling is a method of aqueous surface design, which can produce patterns similar to smooth marble or other kinds of stone. [1] The patterns are the result of color floated on either plain water or a viscous solution known as size , and then carefully transferred to an absorbent surface, such as paper or fabric.

[citation needed] Traces of the writing brush, however, were discovered on the Shang jades, and were suggested to be the grounds of the oracle bone inscriptions.

A small wolf-hair brush that is tapered to a fine point can deliver an even thin line of ink (much like a pen). A large wool brush (one variation called the 'big cloud') can hold a large volume of water and ink. When the big cloud brush rains down upon the paper, it delivers a graded swath of ink encompassing myriad shades of gray to black. [2 ...
The advantage of rasterizing is the near effortless "fill" it produces. Most images to be engraved are bold letters or have large continuously engraved areas, and these are well-rasterized. Photos are rasterized (as in printing), with dots larger than that of the laser's spot, and these also are best engraved as a raster image. Almost any page ...
