The disclosure relates to personalization of objects and more particularly relates to systems and methods for producing microscale optical codes on objects such as jewelry, precious metals, natural or man-made diamonds and natural or man-made gemstones for personalization and scanning the microscale optical codes thereof.
Personalization of various merchandise, and more particularly personalization of jewelry and precious gemstones have been popular among young generations. The merchandise may be jewelry, precious metals, natural or man-made diamonds and natural or man-made gemstones. The jewelry may be a bracelet, wristwatch, ring etc. Personalization includes inscribing names, numbers, personal messages or any specific mark or design on the merchandise. It may be noted that this physical personalization has a limited impact. Hence, to enhance the customer experience, a digital personalization method can be developed which will comprise of an optical code, a scanning technique using a mobile camera and a mobile app which will process the scanned code and connect to a personalized webpage. This personalized web interface can access messages, images, videos linked to that specific jewelry/gem stone. Such personalization requires an inscribing process to create marks and designs. Generally, inscription of macroscale optical codes, such as bar, QR or customized data matrix codes can be performed via laser marking on most of the materials. However, microscale inscription of codes such as optical codes on a piece of jewelry and gemstone rings up many challenges. The challenges arise when inscribing the microscale optical codes with laser process on jewelry due to high reflectivity of the precious metals and gem stones due to their high transmissivity. Further, the scanning of such microscale optical codes is also very difficult as it would require a high-resolution camera.
Other than personalization, microscale inscription of optical codes on the jewelry is used for identification and authorization of the jewelry products and gemstones. In recent times, an appropriate QR or bar code along with the product number is printed on a plug-in label and this plug-in label is then attached to the jewelry. But such plug-in labels may get partially or permanently damaged, and thus may get linked to a wrong product when scanned.
There are various methods and systems developed for inscription of QR/bar codes on articles and jewelries using laser technology. In one method, alpha-numeric numbers are inscribed on diamonds by using the laser technology to certify them. In some other method, a QR code may be located on a wristband or any other wearable object for quickly obtaining medical information. Such medical information is obtained by scanning the QR code on these wearable objects. Similarly, some other methods describe inscription of barcode or QR codes on the surface of the jewelry, where the inscription is performed by making specular reflective and diffusive area on the surface of the jewelry by laser, etching or chemical technique. However, when performing inscription of micro-sized optical codes on articles and jewelry, these conventional methods and systems are not efficient as these techniques damage the surface of the precious material or jewelry.
Thus, there is a need for an improved method and system for inscribing micro-sized optical codes on the surface of the jewelry or precious gemstones with minimal damage to the surface of the precious material of the jewelry or gemstones.
