Abstract:
A method of printing a pattern on a substrate, comprising:applying a photoresist layer over said substrate; locating a laser direct-imaging exposure head with respect to said substrate to print said pattern on the substrate by the application of laser energy to the photoresist layer on the substrate while relative movement is effected between said exposure head and said substrate by a drive; defining a first portion of the substrate to be printed with a first portion of the pattern at a first resolution, and a second portion of the substrate to be printed with a second portion of the pattern at a second, higher resolution; and controlling said drive and said exposure head to cause the exposure head to print said first portion of the pattern on said first portion of the substrate at said first resolution, and said second portion of the pattern on said second portion of the substrate at said second, higher resolution.
