Thermographic printing is a multi-stage process. First, a printed paper drops off the printing press onto a conveyor. The conveyor moves  the  sticky ink underneath the thermograph powder which is shaken  on  top  of the  entire sheet.  The  powder  attaches to the wet ink. The extra powder is then vacuumed up and     stored  for re-use. Next, the  coated  sheet  passes through an oven with temperatures ranging from 900 to 1300 degrees Fahrenheit.
Laser-safe results in thermograph combines a specially formulated powder with an ultraviolet light used  to  harden  or  cure  the  raised stationery so it won't re-melt. This can take place on an in-line machine or the conveyor of the thermograph machine combined with a retrofit unit. This is the most productive and cost-effective procedure and produces a smoother finish on fine lines of type, almost resembling genuine copper plate engraving.
