Abstract:
1. A direct printing method for printing on containers with the aid of a direct printing machine, comprising printing a print layer onto the container, in a first predefined area thereof, in a first device in a first step, and applying a cover layer to the container in a second device in a second step, the cover layer being applied to a second predefined area, which comprises the first predefined area and the surface area of which is larger than that of the first predefined area, the cover layer coalescing with the printing ink in the first predefined area thus creating a first connection, the cover layer coalescing with the container in parts of the second predefined area which differ from the first predefined area thus creating a second connection, and the first and second connections being insoluble in first aqueous solutions having a pH value between 3 and 10 and easily soluble in second aqueous solutions having a pH value in a range of less than 3 and/or higher than 10, wherein the second connection between the cover layer and the container is stronger than a connection between the print layer and the container and the first connection is stronger than the connection between the print layer and the container.
