Jun 16, 2017 Aaron: So here’s where we’re going to talk about efficiency, right? Yes! In screen printing the key factors are 1) the price you charge and 2) how efficient you are at what you do. Two printers could charge \$500 for the exact same order. One printer could have a \$200 profit from the order, and the next printer could lose \$200 on the order.

Sep 11, 2012 Screen efficiency is obtained using different equations, depending on whether your product is the oversize or undersize fraction from the screen. The following information is required to calculate the two screen efficiencies;-Qms(f) = Mass flow rate of solid feed. Qms(o) = Mass flow rate of solid in the screen overflow. Qms(u) = Mass flow rate of solid in the screen underflow.
