Definitions

  • the unitary plate 11 shown is mounted on the cylinder 10 so that its ends 11 are locked in a slot 26 provided in the cylinder 10 so that on the printed stock plate gaps of the width of such slot 26 will appear intermediate the printed complete composite items unless a control of the paper stock feed is exercised in the manner disclosed in said US. Pat. No. 3,610,147.
  • the portion of the complete composite item in each image area of the plate 11 is offset onto a blanket cylinder 30 during each complete revolution of the latter. As the blanket cylinder revolves three times for every revolution of the plate cylinder 10, all of the images constituting the complete composite item will have been applied to the blanket cylinder at the end of such three revolutions thereof.
  • the complete composite item offset onto the blanket cylinder is transferred to the paper stock with the cooperation of an impression cylinder 35 in a known manner.
  • a printing press having a rotatable cylinder, means for mounting on said cylinder printing media including at least one wet offset printing media, and provided with a plurality of separated images for printing a multi-image item on a backing, means for applying ink to all of the separated images on said printing media, means for applying dampening material to the wet offset printing media including a dampening area on said cylinder of fixed extent located adjacently in ading said dampening material applying means to control the extent of the application of dampening material to said dampening area and thereby to control the amount of dampener to be applied to said wet offset printing media, means for contacting said inking means with said dampening area before contacting said wet printing media.
  • said cylinder is provided with a plurality of alternately arranged printing segments and non-printing segments, at least one of said printing segments being a wet offset printing segment, and at least one of said printing segments being a dry offset printing segment, in which said dampening roller is adapted to contact all of said nonprinting segments, and in which said movable means is selectively operable to permit said dampening roller to contact the non-printing segment in advance of the wet offset printing segment and to preventthe contact of said dampening roller with the non-printing segment in advance of the dry-offset printing segment.
