ABSTRACT:
An improved squeegee roller particularly suited for use in an instant camera has a texture formed by stud-like bumps. A complex contour is provided to the roller by varying the heights of the bumps along the roller surface. In a method and apparatus for producing the roller a pulsed laser beam is used to produce the bumps and the energy of each pulse is varied according to a predetermined program to adjust the height of a bump formed.
