A photogravure printing method and machine for printing films (7) uses a water based ink and avoids customary problems associated with wetting of the plate, bleed, fogging and drying by using a printing drum (3) having between 200 and 400 mesh lines with a depth between 10 and 17 mu . Left-over ink...

Zusammenfassung:A photogravure printing method and machine for printing films (7) uses a water based ink and avoids customary problems associated with wetting of the plate, bleed, fogging and drying by using a printing drum (3) having between 200 and 400 mesh lines with a depth between 10 and 17 mu . Left-over ink may be reduced by having an ink reservoir formed with a trough (4) into which the inking roller (2) dips the trough (4) being associated with a drip tray (1a) located beneath the printing drum (3). Printing may be improved further by using a doctor blade assembly (5) having two blades of differing resilience. In a modification two inking rollers are used in spaced relationship at the lower part of the printing drum.
