Register control`s marks detecting and processing arrangement for printing machine, has light emitting diodes array arranged at optical axis of camera in such manner that light rays with line stands perpendicular to print material

摘要

The arrangement has a camera (9), a lighting and an image processing and synchronisation electronics accommodated in a housing (8), where the lighting is made by light emitting diodes array (11). A light entrance opening (7) of the camera is brought in a front edge of the housing. The light emitting diodes array is arranged at an optical axis of the camera in such a manner that light rays with a line stands perpendicular to a print material (2) and forms an angle (4) larger than another angle (5).
