Eight basics to ensure your coding/ marking systems don’t fall down 1. The most expensive ink to buy is often the least expensive ink to use. Using the recommended ink is the simplest and most cost-effective way to get the best performance from your coding and marking machines. Purchasing managers are always bombarded with opportunities to save money, and low-cost ink supplies are always attractive. But keeping coding machines running 100% of the time is essential to efficiency, so spend the money to use high-quality inks. 2. Eliminate variation. To ensure print registration is consistent, the print position and materials must be the same every time. 3. Make sure all components are operating in concert to create a smooth operation. Check that package motion drivers are operating within parameters to prevent skew, flutter and random slip. Also check parameters such as back-pressure, conveyor rail position, and any other components specified by the manual. Verify parameters such as lighting and focal sharpness of lenses. 4. Keep the cooling fans of laser coding machines clear of debris, especially when coding inside a cartoning machine. This is critical to optimum performance. 5. Mind the ink. Ink-jet printers are subject to settling and thickening of the ink. When rotating a coder out of service for maintenance, flush it immediately to clear out old gunk. When it’s ready to go back in service, run the printer in the shop for at least 30 minutes to make sure the ink viscosity has normalized before moving it to production. 6. Protect coding machines from vibration and shock. Conveyors and product on the line can introduce significant sources of vibration. Look into developing a shock absorbent platform for the machines. 7. Control the environment. Keep temperature and humidity at the printing area in a stable range. This promotes proper ink flow and adhesion. When finished, make sure that you leave the coding print head as clean as it was before you started printing. 8. Reduce variability and errors. With digital and variable print, consider what can be preprinted from your vendor so packaging line operators don’t have to worry about coding and marking as a part of their duties.
