  • Patent number: 12188815
    Abstract: Ultraviolet systems and methods are described for capturing images depicting absorption or remittance of ultraviolet radiation (UVR). An example system includes a camera comprising a monochrome camera sensor that is configured to capture images, a radiation source that is configured to output a UVR waveband, a filter component that is configured to differentiate at least one of a UVA waveband and a UVB waveband of the UVR waveband, and a polarizer component that is configured to cross polarize each of the UVA waveband and the UVB waveband. Further, the camera is configured to capture an image depicting an UVA amount of UVA absorption or remittance as projected on a surface area and an UVB amount of UVB absorption or remittance as projected on the surface area.

  • Patent number: 6383575
    Abstract: A method for metallising solid substrates involves the use of non-equilibrium plasma treatment of a supported metal precursor layer. This technique can be used to make pure metal or alloy coatings. An oxidising plasma pre-treatment step of the supported metal precursor layer, or the incorporation of a plasma polymer coupling layer prior to metallisation, can result in improved adhesion. The method can be applied to the preparation of lithographic printing plate precursors.
