ABSTRACT:
Method and apparatus are described for non-impact printing of single and multi-ply business form assemblies, utilizing an electromagnetic radiation reactant chemical mixture which is selectively coated in one or more plies of the assemblies causing the plies to form images when selectively heated by the action of a controlled source by passing the radiation, such as microwave energy, through the business form assemblies.
