Book excerpt: Competition in stencil printing to produce excellence in the finished product is intense. The need to optimize the manufacturing process to establish a fine print is receiving world wide research attention. This paper report the results of an investigation in which the essential parameters of squeegee pressure, squeegee speed,separation speed and print gap are measured and controlled. The analysis is carried out using statistical optimization. The aim is to combine these parameters with three main pitch categories to produce the ideal print formation. The results show that the ideal print result requires that the optimum statistical combinations of the four parameters are essentially related to a particular pitch. It is also shown that there is diversity and contrasts of the combination of the parameters for each category of pitch. Detailed explanations as to the reason for this phenomenon is outlined in the paper. [Authors' abstract].
