Abstract (en)
[origin: WO9742547A1] The invention relates to a process and a device for preparing exposed typesetting films for phototypesetting. In said process, a typesetting film which has a transparent plastic base sheet and at least one surface layer applied thereto is scanned with a laser beam and exposed with respect to picture elements while being guided by the typesetting information. To prepare a typesetting films in a simple and economical manner, it is proposed to use a typesetting film with a carbon black and/or graphite-containing surface layer on the transparent plastic base sheet, and to burn away with the laser beam the surface layer at picture elements to be exposed. Consequently, only the transparent plastic base sheet remains in the exposed areas.
