It is possible to use Protel for this purpose.
Ink areas are merely assigned to internal layers and a composite 
photoplot is made of all layers which are then separated for each 
screen. The resistors that you use in hybrids are then a function of the 
layer and thus the ink resistivity, and the pad shape through the length 
to width ratio. The resistors are then usually trimmed to value with a 
laser trimmer.
