Abstract
Disclosed are apparatus and methods for protecting an optical system from residual material that is scattered and dispersed during the imaging of printing plates and collecting same. The apparatus includes a housing with upper and lower chambers and surrounding at least a portion of the printing drum. The lower chamber is configured to be fitted to the optical system of the imager. A compressed air supply connects to the lower chamber and a suction device connects to the upper chamber for extracting the residual material. Air from the compressed air supply is moved through the lower chamber forming two air-streams, which are drawn into the upper chamber with the residual material of the imaging process.
