HP L5 manual Table of Logical Operations

Table of Logical Operations

Table 2-6, Logical Operations (ROP3), shows the mapping between input values and their logical operations. Note that the logical operations are specified as RPN (reverse polish notation) equations. Here is a key to describe what the Boolean Function values mean;

S = Source	a = AND
T = Texture	o = OR
D = Destination	n = NOT
	x = EXCLUSIVE OR

Note Since logical operations are interpreted in RGB space (white = 1 and black = 0) rather than in CMY space (white = 0 and black = 1), the results may not be intuitive. For example, ORing a white object with a black object in RGB space yields a white object. This is the same as ANDing the two objects in CMY space. It must be remem- bered that the printer operates in something similar to a CMY space and inverts the bits and reverses the order.
