For example, if the paint is applied in a wet film at a 100 μm thickness and the volume solid of paint is 50%, then the dry film thickness (DFT) will be 50 μm as 50% of the wet paint has evaporated. Suppose the volume solid is 100%, and the wet film thickness is also 100 μm.
ISO 3233-1:2019 Part 1: Method using a coated test panel to determine non-volatile matter and to determine dry-film density by the Archimedes' principle ISO 3233-2:2019 Part 2: Method using the determination of non-volatile-matter content in accordance with ISO 3251 and determination of dry film density on coated test panels by the Archimedes ...
China girl, leader ladies, LAD girl or laboratory aim density (LAD) test film, is common name for a color chart test film with a color or black-and-white set up chart and a woman. [citation needed] This would be used stand alone or placed on a film leader, that is at the start of the first roll of film. An LAD patch is neutral gray, with visual ...
First known film is the first film (not including tests) made with the format and intended for release. Negative gauge is the film gauge (width) used for the original camera negative. Negative aspect ratio is the image ratio determined by the ratio of the gate dimensions multiplied by the anamorphic power of the camera lenses (1× in the case ...
Thickness of the paper in relation with GSM. Not only is consistent thickness required in web offset lithography, where varying bulk within a single roll can cause the roll to unwind with uneven tension, which is responsible for various printing defects as well as web breaks. Higher bulk of the same GSM will reduce the show through defects.
Dry film conformal coating thickness measurement. An alternative to wet film measurement is by using eddy currents. The system works by placing the test head on the surface of the conformal coating. When liquid water is present, a pinhole can form in the coating. This is considered a defect and can be eliminated with appropriate steps and training.
