Burn-out printing

Burn-out printing - A method of printing to obtain a raised design on a sheer ground. The design is applied with a special chemical onto a fabric woven of pairs of threads of different fibers. One of the fibers is then destroyed locally by chemical action. Burnout printing is often used on velvet. The product of this operation is known as a burnt-out print.

PCBs. Many products once contained PCBs and were used primarily inside buildings, such as printing ink, carbonless carbon paper, small electrical capacitors, and fluorescent light ballasts. MacLeod (1981) showed that indoor PCB concentrations in offices, private homes, and laboratories were (in the early 1980s) at least lOx and often lOOx higher than outdoor levels. She also sampled an office in which a fluorescent light ballast had burned out and noted that immediately after the burnout, concentrations rose to more than 10 fig/ia and then fell gradually over a period of at least three months to more typical values of 200 ng/m. ...

Color Burn-Out n An objectionable change in the color of a printing ink which may occur either in bulk or on the printed sheet. In the former case it is associated primarily with tints, and is caused by a chemical reaction between certain components in the ink formulation. In the latter case it is generally caused by heat generated in a pile of printed material during the drying of an oxidizing type of ink. 

A C02 laser beam is used to etch (bum in) or bum out (as used for batch coding and expiry dating). In the latter, a prior printed or enamelled surface has some of the ink removed by burning off, as used for batch coding etc. Note that other forms of laser printing processes can produce a high-quality conventional image.
