Lithographic imaging with printing members having metal imaging bilayers

Printing members include very thin metal imaging bilayers that combine to trap and utilize imaging radiation and, due to their minimal thicknesses, ablate easily. The bilayer may include a first (bottommost) metal layer (105a) having a high extinction coefficient in the imaging wavelength range (e.g...

Zusammenfassung:Printing members include very thin metal imaging bilayers that combine to trap and utilize imaging radiation and, due to their minimal thicknesses, ablate easily. The bilayer may include a first (bottommost) metal layer (105a) having a high extinction coefficient in the imaging wavelength range (e.g., 600 - 1200 nm) and, thereover, a second metal layer (105b) having a high transmittance and low emissivity for imaging radiation.
