摘要： A method for making a lithographic printing plate includes the steps of providing a printing plate precursor including a support and photosensitive coating wherein the photosensitive coating includes a photopolymerizable composition; image wise exposing the printing plate precursor on an external drum apparatus emitting one or more scanning laser beams having a wavelength between 390 nm and 420 nm and an energy density, measured on the surface of the precursor, of 100 μJ/cm2 or less; optionally preheating the printing plate precursor; and processing the exposed printing plate precursor with a developer.

摘要： A design for pre-scan optics offers the possibility of low cost field modularity by replacing a rather inexpensive optical sub-module inside the pre-scan optics instead of the entire optics bench in the case of laser failure in a platesetter or imagesetter. It further allows the use of lenses that are highly dispersive and are designed to operate at other wavelengths, such as 780 nm. The correction is distributed over three elements. This allows for collimation in both the X and Y axes of the beam.

摘要： A method and system for calibrating a spatial light modulator, such as a GLV in a printing system detects intensity levels of light provided by elements of the spatial light modulator. It determines control levels for the elements of the spatial light modulator that will compensate for spatial variation in the intensity of light across the spatial light modulator. These changes in intensity can be a result of the changes in properties of the GLV across its length. It can also be the result of changes in the intensity of light provided by the LIM across the spatial light modulator. The compensation comprehends the pulse width changes of the elements of the spatial light modulator, due to changes in the control levels due to the spatial variation compensation. This second level of compensation ensures that changes to the spot size that may result from conventional compensation are comprehended in generating a total compensation scheme that accounts for the dynamics in the operation of the spatial light modulator. Specifically, in one implementation, control levels for the elements of the spatial light modulator are selected to under compensate for the spatial variations to account for changes in the control levels due to the spatial variation compensation.
