[Sovereign Items] 1. A rotary printing press comprising: a first printing device comprising a pair of rollers consisting of a first blanket cylinder and a first plate cylinder for printing on one side of the printing paper First color, and two pairs of rollers - each consisting of second and third blanket cylinders and second and third plate cylinders; these cylinders face each other with respect to the first blanket cylinder, on the other side of the printing paper The first and second colors are printed; the second and third blanket cylinders contact the first blanket cylinder at a predetermined angle with respect to each other, and the printing paper passes through the first, second, and third blanket cylinders. The face-to-face approach is in contact with the first, second and third blanket cylinders; a second printing apparatus includes a pair of blanket cylinders and a pair of plate cylinders. After the printing paper passes through the first printing device, the rollers are positioned on both sides of the printing paper, printing a second color on one side of the printing paper and printing a third color on the other side; and a third printing device including a printer. 4 A pair of rollers consisting of a blanket cylinder and a fourth plate cylinder prints the fourth color on one side after the printing paper passes through the second printing device; and two pairs of 5th and 6th offset cylinders and 5th and 6th respectively.
