ABSTRACT:
A method for the reproduction of an image pattern disposed on a substantially nonuniformly driven scanning drum, wherein the image pattern is photo-electrically scanned point-by-point and line-by-line to generate an image pattern signal having an analog relationship to the image pattern and the image pattern signal is used to record on at least one recording drum driven substantially nonuniformly and independently of the scanning drum, features generating a scanning timing signal in synchronism with the rotational movement of the scanning drum, converting the image pattern signal to a digital signal in synchronism with the scanning timing signal, storing the digital signal in a storage unit measure-by-measure in synchronism with the scanning timing signal, generating a recording timing signal in synchronism with the rotational movement of the recording drum, reading out the digital signal from the storage unit measure-by-measure in synchronism with the recording timing signal, and, thereafter, driving at least one recording member with the digital signal to produce an image reproduction on the recording drum.
