Method for making an image using a direct thermal imaging element

摘要

A method for making an image using a direct thermal imaging element, comprising on a support a thermosensitive layer incorporating an organic silver salt and a reducing agent contained in said thermosensitive layer and/or in other optional layers, said imaging element being imagewise heated by means of a thermal head having energisable heating elements, characterised in that the activation of the heating elements is executed line by line with a line duty cycle DELTA representing the ratio of activation time to total line time, such that the following equation is satisfiedP
