Abstract
A latent image-multiple copy process wherein use is made of a stencil in which stencil openings are formed to correspond to the latent image and base sheets in combination therewith, containing an invisible, soluble, color forming component, whereby when the color forming component is depleted from the base sheet in the area underlying the stencil openings, the base sheet can be replaced for the production of additional copies without the need to provide for a new stencil.
