Abstract
The invention comprises a precursor to an imaged member comprising a dimensionally stable substrate including an imagable coating, on a surface thereon, wherein the non-coated dimensionally stable substrate comprises dimensionally stable paper comprising at least one of the following characteristics: (i) an elastic yield such that the tensile force required to exceed the elastic yield is greater than 60 Nmm−2; (ii) a percentage elongation of the paper under a tensile load or strain at the elastic yield point smaller than 1%; and (iii) a Young's Modulus under tensile load greater than 7 GPa. The invention further extends to a method of manufacturing an imaged member from an imaged member precursor of the invention.
