Abstract: A credential printing device is provided. The credential printing device includes a credential substrate transport, a transfer ribbon and a transfer roller. The credential substrate transport is configured to feed a credential substrate along a processing path. The transfer ribbon is adjacent to the processing path. The transfer roller is positioned below the processing path and is configured to transfer an image from the transfer ribbon to a bottom surface of the credential substrate in the processing path.

Abstract: An analysis test strip and a process for the production of analysis test strips with a longitudinal carrier upon which is fixed at least one test field. The test field material is produced batchwise in an amount sufficient for a plurality of test strips, and thereafter, in a chronologically separate working step, is continuously fixed in the form of at least one band onto a parallel-running substantially wider band of test strip carrier material. The band as a whole is cut up transversely to its longitudinal direction into a plurality of test strips. Prior to the cutting up, a bar code is applied to the carrier band running parallel to the edges thereof of such high information density that it is suitable as a store of batch-specific information necessary for the quantitative evaluation of the reaction which has previously been obtained by investigation of the test field material of one batch.
