Coating defect: small, pore-like holes in a coating film about the size of a pinpoint. Extend entirely through the film.
Small holes (unwanted) in printed areas because of a variety of reasons.
Refers to small holes, free of ink, which appear within a solid ink area often caused by airborn dust settling on the web as it passes into the print units.
Unwanted holes in the printed areas.
An undesirable situation where tiny holes develop in a coating. These holes may allow moisture and contaminants to penetrate the coating and come into contact with the substrate. 437
The term for very small holes found in aluminum foil which dramatically affects MVTR (moisture vapor transmission rate) and OTR (oxygen transmission rate). Thicker foiles have fewer pinholes.
The defect is the appearance of small holes in dried paint film. The problem is most probably caused by too thick a coat trapping solvents into the film, or by air bubbles. The defect may be due to not cleaning the surface before painting, using the wrong solvents in spray painting or incorrect air pressure. The problem can be solved by addressing the above causes.
Condition caused by failure of an ink to cover the surface completely, leaving small holes in the printed area.
Failure of printed ink to form a completely continuous film, visible in the form of small holes in the printed areas.
Small holes, the size of a pinpoint, in the surface of the topcoat that result when small bubbles burst as the paint cures.
A film defect characterized by small, pore-like flaws in a coating which extend entirely through the film.
The formation of minute holes in the dry film, created during the application process.
Holes in the ink film due to localised inability to wet surface. (Reticulation and Cissing).
The appearance of fine pimply defects in a dried film, due to bubbles or other causes, which result in small holes in the film after the tops have been removed by rubbing or sanding.
A defect in a coating characterized by pinhead-sized holes that expose the underlying substrate.
Refers to the failure of a printed ink to form a complete film. This condition will become visible by the appearance of small holes in the solid print area.
Paint defect, often caused by air bubbles, which pits the painted surface, most commonly when paint is sprayed. The trapped air bubbles break, leaving a small hole in the paint surface. Slowly evaporating solvents can also cause this problem. Multiple coats of paint help to prevent it.
