Patent ID: 8715908

Claim:
A method for setting conditions in a device used for making a recording element comprising: a) providing a precursor printing form comprising a layer of a photopolymerizable composition sensitive to actinic radiation from a source of radiation having a range of wavelengths greater than 10 nm, wherein the photopolymerizable layer has a thickness range of 0.010 to 0.250 inch, and wherein a photoluminescent tag excluding optical brighteners is disposed in the precursor printing form and is responsive to at least one wavelength from the source of radiation, the composition being sensitive to the at least one wavelength; b) exposing the precursor printing form to the at least one wavelength to generate an emitted radiation from the tag at a wavelength that is different from the actinic radiation; c) detecting the emitted radiation; and d) setting one or more conditions for operation of the device according to the detected emission from step c).
