5.2 Printing quality 

The examining division has also to check whether the drawings in the printing copy ("Druckexemplar") are suitable for printing. If necessary, a copy of the original drawings must be prepared as the printing copy. If, however, the quality of the original drawings is also insufficient, then the examining division must request the applicant to present drawings of sufficient quality for printing. It needs to, however, beware of any extension of subject-matter (Art. 123(2)).
