A spot printing rotary printing apparatus for sequentially printing a large number of types of spot printing patterns at predetermined positions of each printed material continuously printed at equal intervals in the vertical direction. When the pitch in the direction is A, the number of types of patterns for spot printing is B, and the width of the patterns for spot printing in the vertical direction is C, (1) One cycle for inserting all types of patterns The printing length D is obtained by A × B = D. (2) From the number of teeth Z per unit length of the plate cylinder gear, the equivalent number of teeth E of the plate cylinder gear with respect to the printing length D is D × Z. = E
(3) The number E of rotating teeth of the plate cylinder gear is decomposed into prime numbers. (4) The number B of spot printing patterns is converted into the number E of equivalent teeth.
Of the plate cylinder gear 1 to each value obtained by sequentially multiplying the prime numbers obtained by
Multiply the perimeter F (F 1 ,
F 2 , F 3 ,...), And (5) The total length L of all kinds of patterns in the vertical direction is obtained by B × C = L, and is larger than the total length L and is the closest size. Is adopted as the circumference of the plate cylinder 1,
A pattern plate for spot printing is sequentially arranged for each pitch obtained by dividing the circumference of the plate cylinder 1 by the pattern type B.
Then, the circumferential length is set to the pitch A in the vertical direction of the printed matter or an integral multiple thereof, and the printing pressure portion 4 having a size corresponding to the pattern plate for spot printing is slightly raised at one or an integer position in the vertical direction. A rotary printing apparatus for spot printing, wherein the provided impression cylinders 2 are in contact with each other.
