| description | A method and apparatus for measurement of density of a photosensitive printing plate (130) having a mask (132) embodying image information corresponding to an image to be printed. A density measurement system includes a first radiation source (112) spaced apart from and adjacent the plate and configured to emit radiation having a first wavelength or range of wavelengths toward the plate. A densitometer (110) spaced apart from and adjacent the plate in a fixed relationship relative to the first radiation source receives and measures an amount of the first radiation transmitted through or reflected by the plate and the mask during relative movement between the plate and the density measurement system. The densitometer readings are processed to provide an output correlating to quality of the mask. The density measurement system may be coupled to an exposure system (120,122,124) for curing the plate. |
