Method for direct printing on containers via a direct printing machine, with a print layer printed onto the container, in a first predefined area, in a first device, and a cover layer applied to the container in a second device, the cover layer applied to a second predefined area. A surface area of the second predefined area is larger than that of the first predefined area. The cover layer coalesces with the printing ink in the first predefined area, creating a first connection, and coalesces with the container in parts of the second predefined area differing from the first predefined area, creating a second connection. The first and second connections are insoluble in aqueous solutions having a pH value between 3 and 10 and easily soluble in aqueous solutions having a pH value in a range of less than 3 and/or higher than 10. |
