Abstract
A method of producing a unit pattern on a printing cylinder for printing an endless pattern including the steps of: storing pixel signals expressing pixels of an original picture in memory means; distinguishing the pixel signals into first pixel signals which approximate to respective their corresponding pixel signals distant therefrom by a repetition length in a primary scanning direction and second pixel signals which are much different from the same; producing a cutting line extending across the original picture in a secondary scanning direction, said cutting line passing through the pixels of the original picture expressed by the first pixel signals as much as possible; extracting pattern pixel signals which exist between the cutting line and an imaginary line distant therefrom by the repetition length from the pixel signals; smoothing the pattern pixel signals close to the cutting line and the imaginary line; and recording the unit pattern on the printing cylinder on the basis of the smoothed pattern pixel signals.
