    Abstract: A method of making a lithographic printing plate comprising the steps of: a) image-wise exposing a lithographic printing plate precursor, the printing plate precursor comprising a hydrophilic support and a coating comprising a colorant precursor provided thereon, thereby forming a lithographic image consisting of printing areas and non-printing areas; and b) developing the plate precursor, thereby removing the coating in the non-printing areas from the support; and c) drying the plate precursor; and d) subjecting the lithographic plate to heat or radiation, thereby inducing a colour change of the coating in the printing areas; wherein - before step b) the coating in the non-printing areas and the support are characterised by a CIE 1976 colour difference Δ E 1 which is 5.0 or less; - after step d) the CIE 1976 colour difference Δ E 2 between the coating in the printing areas and the non-printing areas is more than 6.8.
