Abstract
A system and method for highlighting indicia on a printed page that includes applying a compound to a printed page that is in a transparent clear state and providing an actuator that when applied to the compound causes the compound to change to a transparent color state for visually highlighting the indicia on which the compound is applied. An optional deactivator causes the compound to change from the transparent color state to the transparent clear state.
Claims25
A system for highlighting, comprising:
- a compound produced on a reading surface that is transparent;
- and
- an activator for application to the compound to activate the compound when applied thereto and to cause the compound to change from a transparent state to a nontransparent state to present a visually-distinct highlighting indicia underlying the compound.
A method of highlighting, comprising:
- applying a compound to a reading surface as a latent image with fixed dimensions and color, the compound having a transparent clear state;
- and
- applying an activator to the compound to cause the compound to change from a transparent clear state to a transparent color state that contrasts with a color of the printed page and visually highlights indicia underlying the compound.
An indicia illuminating system, comprising:
- a transparent compound on a reading surface;
- and
- an activator for application to the transparent compound that interacts with the transparent compound and changes the appearance of the reading surface to present a visually-distinct color for highlighting indicia underlying the transparent compound.
