Roland DGA - Understanding and Interpreting Ink Expiration Dates for Eco-Solvent Inks

Introduction:

Understanding the expiration date of ink cartridges is essential for ensuring optimal printing results and avoiding issues such as clogging or poor print quality. This support article provides detailed instructions on how to identify and interpret the expiration date of eco-solvent inks used in printing applications.

Locating the Expiration Date:


  • To find the expiration date of eco-solvent inks, examine the bottom of the ink cartridge.
  • The expiration date is represented by the manufacturing date imprinted on the cartridge.

Interpreting the Manufacturing Date:

  • The manufacturing date is indicated by the first 4 digits printed on the cartridge.
  • The first digit signifies the last digit of the manufacturing year. For instance, if the first digit is "3," it indicates the ink was manufactured in 2013.
  • The second digit denotes the manufacturing month. The months are represented as follows:
    • 1 to 9 correspond to January to September.
    • A represents October.
    • B represents November.
    • C represents December.
  • The next 2 digits represent the day of manufacturing.
  • The remaining digits are the serial number of the cartridge.

Example:

  • For example, if the cartridge's manufacturing date reads "3204," it indicates that the ink was manufactured on February 4, 2013.

Determining the Expiration Date:

  • The expiration date of eco-solvent inks depends on their shelf life, which is typically 24 months.
  • To calculate the expiration date, add 24 months to the manufacturing date.
  • For example, if the ink was manufactured on February 4, 2013, it will expire on February 4, 2015.

Conclusion:

Understanding how to identify and interpret the expiration date of eco-solvent inks is crucial for maintaining print quality and preventing issues related to expired ink cartridges. By following the guidelines outlined in this article, users can effectively manage ink inventory and ensure optimal performance from their printing equipment.
