Zusammenfassung:	Methods of manufacturing multi-layer thermally imageable elements useful as lithographic printing plate precursors are disclosed. The elements comprise a substrate, an underlayer, and an imageable layer. The imageable layer comprises a first polymeric material and o-diazonaphthoquinone containing material. After the underlayer has been coated over the substrate and the imageable layer has been coated over the underlayer, the element is heated to between about 130° C. and about 200° C. for a time sufficient to decrease the sensitivity of the imageable element to the white light.
