Press

Enter a value that the press will achieve per hour in normal production that corresponds with the Costing Method chosen.

 

Costing Method : Impressions Per Hour

This is the way a traditional press calculates the quantity required.

Press Time = (Press Sheets * Number of Side * Passes ) / Units per Hour

 

Costing Method : Feet per Minutes

Typically used for Flexo presses.

 

There are 2 ways the calculation will work depending on the option set in the Roll Rewind/Wide Format/Other tab

 

 

Manual

 

	Formula : Press Quantity in Feet = (Quantity * (Size Around + Space Around )) / 12 * this should equal the cylinder around value. See Max Up ... feature to automatically calculate these values.
	(10,000 * ( 6 + 2 )) /12 = 6,667
	Formula : Production Time = Press Quantity in Feet / (Feet per Minute *60)
	6,667 / (1000 * 60) =  6.67 hours

 

Calculation specifically for the HP Indigo WS6800

 

	Formula : ( Size Around + Space Around ) * Number Around = Repeat Length * this should equal the cylinder around value. See Max Up ... feature to automatically calculate these values.
	( 5 + 0.5 ) * 2 = 5.5 * 7 = 38.5 ( Repeat Length)
	Formula : (Repeat Length / 12 /((colors) * .5 )) * 60
	( 38.5 / 12  / ( 4 *.5 )) * 60 = ( 3.21 / 2 ) * 60 = 1.604 * 60 = 96 feet per minute or 5760 feet per hour

 

Costing Method : Feet per Minute

This costing method should be used for perfecting presses that with remain in perfecting mode. The calculation will efffectively reduce the press speed in half to accommodate the
