According to the invention, a method for direct printing on containers, such as bottles, via a direct printing machine, with a print layer printed onto the container, in at least a first predefined area, in a first device, and a cover layer applied to the container, in a second predefined area, in a second device. The second predefined area comprises the first predefined area and a surface area which is larger than. The cover layer coalesces with 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.
