Imageable elements with colorants

A method of providing a lithographic printing plate comprising:

• A) imagewise exposing the imageable element comprising a substrate and comprising thereon a radiation-sensitive imageable layer to provide exposed and non-exposed regions in the radiation-sensitive imageable layer,
• the radiation-sensitive imageable layer comprising at least one pigment colorant that does not change color when heated, and at least one dye that can change color when heated, wherein the dye is soluble in the solvent or mixture of solvents used to coat the radiation-sensitive imageable layer on the substrate and the pigment colorant is not, and wherein the pigment colorant and the dye independently have a maximum absorption of from about 480 to about 700 mu,
• B) processing the imagewise exposed imageable element to provide a lithographic printing plate, and
• C) baking the lithographic printing plate at a temperature of from about 150° C. to about 300° C.,
• wherein the optical density of the lithographic printing plate, as measured using a cyan filter, of the exposed regions:
• i) after steps A and B and before step C is at least 0.7,
• ii) after steps A, B, and C is at least 0.5,
• the difference between the optical density of the exposed regions before step A and the optical density of the exposed regions after step B but before step C, is less than 0.05, and
• the difference between the optical density of the exposed regions between steps B and C, and the optical density of the exposed regions after step C, is at least 0.2.
