Title:
FILM EXPOSURE METHOD
Document Type and Number:
WIPO Patent Application WO/2012/063632
Kind Code:
A1
Abstract:
A side portion coating film (22) is formed on at least one of the side edge portions in the width direction of a film (2) by applying a colored firing material, a colored photocurable material or a colored ink thereto, said film (2) being provided with an exposure material film (21) in a region for exposure pattern formation on a film base (20). An alignment mark (2a) is formed by irradiation of laser light by means of an alignment mark-forming section (14). Meandering of the film is detected using the alignment mark (2a), and the position of a mask (12) is adjusted accordingly. Consequently, when a film wherein an exposure material film is formed in a region for exposure pattern formation on a film base is continuously exposed, formation of an alignment mark and detection of a formed alignment mark can be carried out easily. Meandering of the film can therefore be accurately corrected, so that the film can be stably exposed.
