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.
Claims11
A method comprising:
- a) projecting a computer programmed 3-D image with a laser on a work piece at a beam scan speed in a projecting mode;
- b) applying a photosensitive composition to the work piece as directed by the image formed on the work piece in the projecting mode;
- c) reducing the beam scan speed of the computer programmed 3-D image to a beam scan speed in a image recording projection mode to form a pattern on the photosensitive composition.
