The Grafopress

23rd October 2012

Made in Czechoslovakia the Kovo Grafopress was an automatic platen

Made in Czechoslovakia the Kovo Grafopress was imported into the UK by Cropper, Charlton & Co Ltd. It was an automatic platen for sheet sizes up to 10.25 x 13.75 inches and an output of up to 5,000 impressions per hour. The Grafopress was the same as other automatic platen machines, but with several improvements to the inking system. A knurled hand-wheel gave screw adjustment of roller track height, whether the machine was stationery or running; both tracks could be lifted or lowered simultaneously, and individual regulation of each track was possible by a cam.  Inking could be suspended completely by a lever fitted to the central screw that lifted both tracks so that the rollers did not make contact with the forme. Inking could be suspended at any time without disturbing the duct setting. It was also possible to suspend the inking rollers while the machine was running. A lever was pressed down and the rollers remained in their upper position on the large distribution roller. This helped give rapid saturation and good distribution when running up a new colour. Access to the forme was easier for insertion, makeready and fixing of the lays. The machine came with a speed range from 2,000 to 5,000 iph. On request it could be equipped for 1,500 and 4,500 iph.
