I figured such, Jim...

PDN is inkjet only, because it involves using ink color to block light (UV 
density).

Hi, Paul...I am the "Facebook Jim" that responded to a question from Alan
about whether I used PDN or QTR. I make my gum prints using laser
transparencies and knew that QTR was meant for ink jet printers. But, did
not realize that Mark's PDN applied to laser printer output. (I am going to
look into this some more). I don't think that I would have referred to ink
jet laser prints. At least I hope that I didn't ;o)
