Folded substrate, dual-sided printing process and substrates printed thereby

A low basis weight substrate is printed by a folded substrate, dual-sided printing process. The substrate is folded to present two printing surfaces. The folded substrate is then passed through a printing station to have an ink pattern printed on one surface, and then is reversed to have a second pattern printed on the second printing surface. Any ink striking through one of the surfaces is collected by the other surface of the printed substrate.

Impression cylinder or intermediate cylinder

Method of printing on substrate

FIELD: printing on substrate with low specific weight. SUBSTANCE: method involves folding substrate so as to form two printing surfaces; directing folded surface through printing station for applying ink pattern on one half of surface; overturning substrate and applying second pattern on second half of surface. Any amount of ink passed through one of surfaces is retained on other surface of substrate with applied pattern. Such construction allows ink to be prevented from penetration through material.

Blower device in printing machines

The invention relates to a blower device in printing machines to avoid the printed sheet becoming smeared on adjusting elements, said adjusting elements being located in the region of the sheet-conveying path on the side of the printed surface of the sheet. The aim of the invention is to provide a blower device with which the printed sheet can be conveyed through the printing machine without becoming smeared. The object of providing a blower device, which allows the point of action of the compressed air to be placed near to the adjusting element despite a small installation space and through which, additionally, only a small quantity of air blows into the storage space, is achieved in that an oncoming flow profile is arranged between the blower tube and the impression cylinder, and the nozzles of the blower tube are directed onto the periphery of the oncoming flow profile which points towards the contact zone of the impression cylinder and the rubber-covered cylinder.

Lightweight portable compact universal printer coater adaptable to printing units on the same press or other presses of the same nominal printing width

A lightweight portable compact flexographic universal printer coater adaptable to printing units on the same press or other presses of the same nominal printing width. The printer coater has a frame which comprises an anilox roller, a means to rotate the anilox roller at or near the surface speed of the rotating printing surface, a liquid film supply for replenishing the liquid film on the surface of the anilox roller, and a positioner device to place the printer coater between the on and off-impression positions. The printer coater apparatus is placed onto at least one pair of fixed supports mounted on the printing press frame so that the positioner apparatus can place the printer coater between an on and off-impression position. Spacers of selected widths may be mounted between the fixed supports and the interior surfaces of the press frame to compensate for slightly varying press frame widths associated with different press manufacturers. In the alternative, fixed supports may be manufactured in different widths and mounted on the interior surface of the press frame to avoid the use of spacers. The printer coater is portably liftable into and out of position from the printing press frame and easily transportable to any printing unit of a multiple unit rotary offset lithographic printing press or other rotary offset lithographic presses of the same nominal printing width.

Vacuum transfer apparatus for rotary sheet-fed printing presses

A vacuum assisted sheet transfer assembly to has an array of support bars 46 which guide the unprinted side of a freshly printed sheet S along a curved transfer path P. The support bars overlie the airflow inlet 44 of a manifold housing 16, with the support bars providing smooth surfaces for engaging and supporting the unprinted side of the sheet material as it is pulled along the transfer path while simultaneously limiting the flow of inlet air through elongated inlet apertures 52, 54. As air is drawn through the inlet apertures 52, 54, the unprinted side of the sheet is drawn into engagement with the support bars as it moves along the sheet transfer path. The sheet transfer assembly 10 eliminates the need for conventional skeleton wheels and the like. Marking, smearing and smudging are prevented since the printed side of the sheet S is not handled or contacted in any way as the sheet is conveyed along the transfer path p.
