A process for adjusting the energy of an imaging laser for element and thermally
imageable elements suitable for this purpose are described. The process comprises
the steps of: (a) providing an imaging unit having a non-imaging laser and an imaging
laser, the non-imaging laser having a light detector which is in communication
with the imaging laser, (b) contacting a receiver element with the thermally imageable
element in the imaging unit, wherein the thermally imageable element comprises
a light attenuated layer having a front surface and a back surface; (c) actuating
the non-imaging laser to expose the thermally imageable element and the receiver
element to an amount of light energy sufficient for the light detector to detect
the amount of light reflected from the light attenuated layer of the thermally
imageable element; and (d) actuating the imaging laser to focus the imaging laser
in order to expose the thermally imageable element to an amount of light energy
sufficient for imaging the thermally imageable element. The light attenuation is
achieved by use of a light attenuating agent or by physically roughening a base
element of the thermally imageable element.
