Abstract
A printing system including a substrate and a dual-mode printing device, the dual-mode printing device including a permanent writing source and a transient writing source, wherein the permanent writing source is adapted to deposit an imaging material onto the substrate and the transient writing source is adapted to develop an image on the substrate by applying a stimulus to the substrate.
Claims20
A printing system comprising:
- a substrate;
- and
- a dual-mode printing device including a permanent writing source and a transient writing source, wherein said permanent writing source includes an imaging material to be deposited onto said substrate to form a first image, and wherein said transient writing source is adapted to apply a stimulus to said substrate to develop a second image on said substrate.
A dual-mode printing device comprising:
- a housing;
- a permanent writing source connected to said housing, said permanent writing source including an imaging material;
- and
- a transient writing source connected to said housing, said transient writing source including a light generating device adapted to selectively communicate light to a substrate.
1 more element
A printing system comprising:
- an erasable substrate including a photochromic material;
- and
- a dual-mode printing device including a printhead and an ultraviolet light source, wherein said printhead is adapted to deposit ink or toner onto said erasable substrate and said ultraviolet light source is adapted to activate said photochromic material from an un-imaged state to an imaged state, and wherein said activated photochromic material is returnable to an un-imaged state.
