Abstract

PURPOSE:To prevent the density differnce in a joint, by forming patterns continuous to the leading end and the trailing end with an extension and converting the signal at one end to the signal at the other end gradually in case that an endless print is made from an original for endless pattern. CONSTITUTION:A pattern continuous to a leading end A or a trailing end B is formed with a slight extension (B-D) as an original 10, and a digital density signal obtained by scanning the original is inputted to a computer. In the computer, the signal for this extended section is used to correct the density signal of the other corresponding end so that the signal in one end is converted to the signal in the other end gradually, and an endless print is made on a basis of the corrected density signal. Thus, even if an original having a density gradation in a joint is used, an endless print without difference in density gradation is made.
