The process of removing dust particles from hard surfaces. A damp cloth, sponge or wiper can be an effective dusting tool. Wool dusters and wipers can also be used if approved by your supervisor. Be careful to use a dusting method that does not stir up dust particles into the surrounding air. These particles can be harmful to people with asthma or respiratory illnesses.

The accumulation of loose particles from the paper on the non-image areas of the blanket. Particles are of very small size.

Applying powder to rubber to prevent adhesion to something else.

Coating dust or filler which builds on the blanket in the non-image area. Also running paper through the press without ink to get rid of dust on the paper. MBOSSING: Pressing a shape or letters into a sheet of paper with a metal or plastic die, creating a raised (embossed) image. ELT SIDE: The side of a sheet of paper which is not in contact with the fourdrinier wire during paper making.

A condition that develops in one to seven days on the surface of uncoated and unprotected spray foam due to photo oxidation by ultraviolet light (sunlight). The ultraviolet causes the surface to break down and become a dust or powder, which impairs adhesion of coatings and blows away. When this occurs, the foam changes from its original light color (usually tan) to a rust or dark brown.

Pölyäminen Dammning Release of filler and other fine material of paper during printing. Cutter and slitting dust seen on web and sheet edges on the printing blanket.

In copper gravure, the grain resist is created by dusting the plate. In polymer photogravure, the aquatint screen is made by dusting a glass plate with fine asphaltum powder. Dusting takes place in a dusting box, a large swivelled airtight container in which asphaltum dust is disturbed and then allowed to settle on a glass plate placed in the box at the appropriate moment. Since large asphaltum particles come to rest first, the grain will be finer the later the plate is placed in the box, after the large particles have already settled. Dusting can be repeated several times.

Powder on the surface of hardened concrete coming from the concrete itself. A surface defect.

Powdery surface, which forms on newly, installed concrete.
