Screen Printing Formulas

All costs for these processes are included in additional direct costs. Cycle time and labor time are 0.

Additional Direct Costs = Screen Printing Cost / Final Yield

Additional direct costs depend on the following:

• Screen printing cost (see the formula below)

• Final yield (see Surface Treatment Yield Calculations)

Screen Printing Cost =

Application Cost per Part * (Cost Color Multiplier + Complexity Multiplier + Size Multiplier)

Screen

• Application Cost per Part (see formula below)

• Cost Color Multiplier (see formula below). This increases the cost as the number of colors used increases.

• Complexity multiplier (0 by default, or specified by the PSO Complexity of Print)

• Size multiplier: This value is looked up by screen length and width in the lookup table screenPrintSizeMult. Screen length and width are part length and width by default, or are specified by the PSOs Length of Screen Print and Width of Screen Print.

Application Cost per Part = Application Cost * Application Area

Application cost per part is the product of the following:

• Application cost (specified in cost per meter2 by the machine property Application Cost)

• Application area (the product of part length and width by default, or the product of the PSOs Length of Screen Print and Width of Screen Print)

Cost Color Multiplier = {

(1 + Color Multiplier) * (Number of Colors - 1), if Number of Colors > 1

0, otherwise}

Cost color multiplier is a function of the following:

• Color multiplier (specified by the cost model variable screenPrintColorMultiplier; 0.75 in aPriori starting point VPEs)

• Number of colors (specified by the cost model variable defaultNumScreenPrintColors, 1 in aPriori starting point VPEs; or specified by the PSO Number of Colors Used on Screen Print)
