摘要: The invention pertains to the use of sophisticated chemical formulation and spectroscopic design methods to select taggants compatible with the 3D print medium that are easily detected spectroscopically but otherwise compatible with the product, structural integrity and stability, and aesthetics. A spectral pattern employs a different chemical or combination of chemicals to alter the formulation of all or some portion of the printed object so that its authenticity can be monitored later using a spectrometer.

摘要: Disclosed are two-dimensional dot matrix barcode encoding and reading methods. A two-dimensional dot matrix barcode is composed of M×N virtual code point storage blocks. The method comprises: forming a plurality of coordinate calibration blocks, a plurality of data storage blocks and a direction indication block by filling code points into the virtual code point storage blocks, wherein the plurality of coordinate calibration blocks are filled with only one code point located in the center of the virtual code point storage block; the direction indication block is filled with at least two code points, only one code point being located in the center of the virtual code point storage block; the plurality of coordinate calibration blocks and the direction indication block are separated from each other and distributed among the plurality of data storage blocks; and code points filled in the plurality of data storage blocks are used to store data information, where M≥4, N≥4, and M and N are both even numbers. The present invention has the advantages of having a large encoding capacity and small interference to human vision, and being simple and reliable to identify.

摘要: Ein Glasrohr-Halbzeug oder ein Hohlglasprodukt, das aus einem Glasrohr-Halbzeug hergestellt ist, ist mit einer ersten Markierung mit Information zur Herkunft und/oder zu rohrspezifischen Produktionsdaten des Glasrohr-Halbzeugs (1) versehen, die auf dem hergestellten Hohlglasprodukt (20) nach dessen Herstellung auslesbar ist, um eine Entscheidung zur Herkunft und/oder zu den rohrspezifischen Produktionsdaten des Glasrohr-Halbzeugs (1) zu ermöglichen.
Durch Auslesen der Markierung lässt sich erfindungsgemäß eindeutig feststellen, aus welchem Glasrohr-Halbzeug das Hohlglasprodukt hergestellt ist. Ferner lassen sich auch rohrspezifische Produktionsdaten dieses Glasrohr-Halbzeugs unmittelbar ermitteln und rückverfolgen. Somit lässt sich für das Hohlglasprodukt die gesamte Lieferkette vom Lieferanten des ursprünglich verwendeten Glasrohr-Halbzeugs bis hin zum Endprodukt eindeutig ermitteln.
Erfindungsgemäß werden zur Erzeugung der ersten Markierung die physikalischen und chemischen Eigenschaften des Glasrohr-Halbzeugs nicht verändert, was durch Aufbringen einer Markierung mittels eines Druckers, beispielsweise eines Tintenstrahldruckers, oder mittels eines Lasers in einfacher Weise realisiert werden kann.-
