ANSI/NIST-ITL 1-2011 - UPDATE 2013 DRAFT VERSIONthe requirements specified in Section 5.1.8.3 Record Type-3: DeprecatedSee ANSI/NIST-ITL 1-2007 or ANSI/NIST-ITL 2-2008 for the specifications of thisRecord Type. No instances of Record Type-3 shall be included in a transactionconformant with this version of the standard.8.4 Record Type-4: Grayscale fingerprint imageThe Type-4 record is based on the use of a captured fingerprint image obtained using aclass scanning resolution of the 500 ppi class. (See Section 7.7.6). Record Type-4 cannotbe updated to include new fields, since the Traditional encoding for this record type isfixed in order. It shall not be used for other than 500 ppi class images. All images thatare compressed should be compressed using WSQ. JPEG compression is retained solelyfor backwards compatibility with legacy systems and it should not be used in any newimplementation.[2013a>] For Traditional encoding, please see Annex B: Traditional encoding,Section B.2.2 Type-4 record. For XML encoding, please see Annex C: NIEMconformantencoding rules Section C.10.4 Type-4 fingerprint image record.[
