The error is known as an offset error. The OP's note is a partial back-to-front offset error.
Under normal circumstances, a sheet is fed into the press between the inked printing plate and the impression cylinder. The impression cylinder pushes against the paper forcing it to accept the ink from the intaglio recesses of the printing plate. The error occurs when a sheet fails to enter press and the impression cylinder contacts the inked printing plate. The next and subsequent sheets receive not only the intended printing but also the inking transferred to the impression cylinder.
