Abstract
An imaging method is disclosed. An imaging composition is coated on a work piece followed by applying a sufficient amount of energy from a 3-D imaging system to form an image on the coated work piece. The image may be a logo or marker for alignment of parts.
Claims9
A method comprising:
- c) applying an imaging composition comprising one or more cyclopentanone based conjugated photosensitizers and one or more reducing agents chosen from quinone compounds and acyl esters of triethanolamines to a work piece;
- and
- d) projecting a 3-D image with a laser onto the imaging composition at 5 mW or less to affect a color or shade change in the imaging composition to form an image on the imaging composition.
A method comprising:
- a) providing an imaging composition comprising one or more cyclopentanone based conjugated photosensitizers and one or more reducing agents chosen from quinone compounds and acyl esters of triethanolamines, the imaging composition is applied to a film substrate with an adhesive applied to an opposite side of the film substrate;
- b) applying the imaging composition on the film substrate to a work piece;
- c) providing a 3-D imaging system for projecting a 3-D image with a laser onto the imaging composition;
- d) measuring a distance between a projector of the 3-D imaging system and at least one reference sensor on the work piece;
- e) applying algorithms to position the 3-D image onto the imaging composition;
- and
- f) applying the 3-D image onto the imaging composition at 5 mW or less to affect a color or shade change in the imaging composition to form an image on the imaging composition.
