Abstract
A reveal substrate includes a sensitive substrate having an opaque polymer sensitive to application of one of heat and pressure which upon one of being heated to a predetermined temperature and subjected to a predetermined pressure causes the opaque polymer to become transparent and a color material disposed in relation to the substrate in a manner to be obscured by the opaque polymer prior to one of the application of the predetermined heat and the predetermined pressure and is revealed subsequent thereto. A method of printing employing the reveal substrate is also provided.
Claims21
A reveal substrate, which comprises:
- a sensitive substrate having an opaque polymer sensitive to application of one of heat and pressure which upon one of being heated to a predetermined temperature and subjected to a predetermined pressure causes said opaque polymer to become transparent;
- and
- a color material disposed in relation to said substrate in a manner to be obscured by said opaque polymer prior to one of said application of said predetermined heat and said predetermined pressure and is revealed subsequent thereto.
A method of thermal printing, which includes the steps of:
- (a) employing a reveal substrate having sensitive substrate having an opaque polymer sensitive to application of one of heat and pressure which upon one of being heated to a predetermined temperature and subjected to a predetermined pressure causes said opaque polymer to become transparent and a color material disposed in relation to said substrate in a manner to be obscured by said opaque polymer prior to one of said application of said predetermined heat and said predetermined pressure and is revealed subsequent thereto;
- and
- (b) employing a printing device to cause one of said application of heat and pressure to a region of said sensitive substrate to render a useful and readable printed reveal substrate having visible said color material through said region.
