Abstract (en)
[origin: US4549067A] An electron beam generator designed for engraving surfaces of printing form cylinders is switched to microscope operation during engraving pauses in order to make engraved cups visible immediately and without additional auxiliary equipment. During microscope operation, deflection parameters and an intensity of an electron beam produced by the electron beam generator are changed for appropriate scanning. An image signal is acquired by detecting secondary electrons generated by the beam interacting with the cups in the printing form surface.
