Abstract
The present invention aims at providing an improved sheet-fed printing press by which simple hologram surface can be, in line, formed on the printed sheet surface. To effect after-treatment, varnishing unit 24 is provided in succession to printing unit 10 and the varnishing unit 24 coats UV-setting-type varnish on the sheet 22. Following the varnishing unit 24, holographic finishing unit 38 is connected which comprises feeding means 44 for casting film 42 on which formed is hologram surface beforehand. The casting film 42 is led near the periphery of pressure cylinder 40 by feeding means 44 in synchronism with printing speed. Hologram surface of casting film 42 is pressed onto the coated sheet 22 by a pair of rollers 52, 54 which can controllably be positioned at make or break state in relation to the pressure cylinder 40. Between the pair of rollers 52, 54, UV lighting means 56 controllably emits UV ray toward the pressure cylinder 40. Added value of printed matter can efficiently be raised, as hologram surface can be, in line, formed at desired position in synchronism with printing speed.
