摘要：A process for adjusting the energy of an imaging laser for imaging of athermally imageable element and thermally imageable elements suitable for thispurpose are described, which is useful for color filters and liquid crystal display devices.The process comprises the steps of: (a) providing an imaging unit having a non-imaginglaser and an imaging laser, the non-imaging laser having a light detector which is incommunication with the imaging laser; (b) contacting a receiver element with thethermally imageable element in the imaging unit, wherein the thermally imageableelement 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 thereceiver element to an amount of light energy sufficient for the light detector to detectthe amount of light reflected from the light attenuated layer of the thermally imageableelement; and (d) actuating the imaging laser to focus the imaging laser in order to exposethe thermally imageable element to an amount of light energy sufficient for imaging thethermally imageable element. The light attenuation is achieved by use of a light

attenuating agent or by physically roughening a base element of the thermallyimageable element.
