Paste Transfer in the Screening Process 680796

This discussion describes the relationships of the amount of paste deposited on a ceramic substrate by screening, to certain aspects of the screening process - - such as the mesh size, paste rheology, line width, etc. It is not intended to be a vigorous mathematical or mechanical analysis of the process.
The conclusions can be extrapolated not only to an understanding of a part of the mechanism of paste transfer, but to a prediction of screened thickness - - as well as to methods for increasing the uniformity and thickness of screened images. Emulsion screens with stainless steel mesh and etched metal masks are discussed.
