ABSTRACT:
A copy sheet that is capable of being printed by a reaction which requires the presence of three components. One of these components is carried by a printing master and another of these components is supplied to the copy sheet immediately prior to the printing operation. The third component is carried by the copy sheet in the form of a layer provided on one side of a carrier sheet forming part of the copy sheet. The printing master is placed on a rotating drum and the layer on the carrier sheet is moistened to supply the still missing component and is thereafter urged into contact with the printing master by means of a counter-pressure roller. If, in making a series of prints on a number of copy sheets, one copy sheet in the sequence should fail to be conveyed to the printing location, the rotating printing master will contact the counter-pressure roller and apply thereto the component carried thereby. This gives rise to the problem that the back side of the next copy sheet will be printed by the counter-pressure roller since this side is moistened and also normally includes at least a small amount of the third component required for the reaction. This problem is eliminated by providing a layer on the back side of the copy sheet which is free of the third component.
