Abstract
Methods of imaging are disclosed. Imaging compositions which are sensitive to low levels of energy are applied to a work piece. Energy is applied to the imaging compositions to cause a color or shade change such that workers may modify the work piece based on the color or shade change.
Claims10
A method comprising:
- a) providing a composition comprising one or more sensitizers and one or more photoreducing agents;
- b) applying the composition to a work piece;
- c) exposing the composition to energy at powers of 5 mW or less to affect a color or shade change to form an image on the composition;
- and
- d) executing one or more tasks on the work piece as directed by the image.
2 more elements
A method comprising:
- a) providing a composition comprising one or more sensitizers and one or more photoreducing agents;
- b) applying the composition to a work piece;
- c) selectively exposing the composition to energy at powers of 5 mW or less to affect a color or shade change to form an image on the composition;
- d) selectively removing portions of the composition as directed by the image to expose portions of the work piece;
- and
- e) executing one or more tasks on the exposed portions of the work piece.

A method comprising:
- a) providing a composition comprising one or more sensitizers and one or more photoreducing agents;
- b) applying the composition to a work piece;
- c) selectively exposing the composition to energy at powers of 5 mW or less to affect a color or shade change to form an image on the work piece;
- d) machining the work piece as directed by the image to modify the work piece;
- and
- e) joining the modified work piece to one or more component parts to form an article.

A method comprising:
- a) applying a primer composition to a work piece;
- b) applying a composition comprising one or more sensitizers and one or more photoreducing agents to the primer on the work piece;
- c) selectively exposing the composition to energy at powers of 5 mW or less to affect a color or shade change to form an image on the composition;
- d) executing one or more tasks on the work piece as directed by the image;
- e) peeling the primer and composition from the work piece;
- and
- f) joining the work piece to one or more parts to form an article.
