What is a Date Coding Machine?

A Date Coding Machine, also known as a date printer or date coder, is a device used to print production or expiration dates, batch numbers, and other relevant information on various products or packaging materials. Date coding machines can utilize various technologies for printing, including inkjet printing, thermal printing, laser printing, and embossing, depending on the specific requirements of the application.

The RNJet H1+ date coding machine is a type of inkjet printer commonly used for date and lot coding on various surfaces, including cans. The best spot to print on cans typically depends on factors such as the design of the can, the printing technology being used, and any regulatory requirements. However, there are a few common locations where printing on cans is often done:

  • Top Lid: Many cans have a flat top lid where printing can be easily applied. This area provides a large, flat surface for clear and visible printing.
  • Side Seam: Printing on the side seam of the can is another common location. This area allows for continuous printing around the circumference of the can, providing ample space for information such as production dates, lot numbers, and barcodes.
  • Bottom: Some cans may have printing applied to the bottom. This area is often used for essential information like expiration dates or batch codes.
  • Body: Depending on the can’s design and the printing technology being used, printing can also be applied directly to the body of the can. This location may offer high visibility and accessibility.
  • Shoulder: Some cans have a shoulder area between the body and the top lid, which can be used for printing additional information or branding.

When determining the best spot for printing on aluminum cans, it’s essential to consider factors such as the ease of application, readability, potential interference with packaging machinery, and regulatory requirements. Conducting tests and trials with your specific printing equipment and can designs can help identify the optimal printing location for your needs.
