The traces must be made visible by the dust-in process and then removed by means of a film — see special installation — (b) Papers. Dactyloscopic traces on papers must be visible in the iodine procedure and then kept in a photographic position. Papers which are to be examined for fingerprints should not be folded as far as possible, should only be handled carefully and placed, if possible, in a paper insert which must be designated accordingly when forwarded to the EFAS. Where there are insufficiently trained forensic security officers at the police outposts, in particular in important cases, documents (papers) suspected of dactyloscopic traces shall be submitted to the competent KP(L)St - EFAS.
