Egg Inkjet Coding and Laser Coding
The two main ways to print traceability and market information on eggshells are continuous ink jet (CIJ) and laser coding (Laser). Almost all printing is done using inkjet coding. But some believe that laser coding could be a viable alternative to inkjet coding in the future. So, which technology is the best?
How does labeling affect eggs? CIJ can deposit ink on the egg surface with little risk to the egg surface integrity, laser marking is an ablative process in which the laser etches the top surface of the egg.
Laser coding solutions require a large up-front investment. Unlike laser coding, small character coding systems usually require a lower up-front investment, but require the purchase of consumables and regular maintenance.
By using small character coding technology on compatible graders, operators can control all printers from a central location in the grader. Laser coders require a printer interface that the grader cannot directly control.
Which is the best solution, small character coders or laser coders? This depends on restrictions imposed by local or export requirements, the combination of egg colors running on the equipment, the egg wetness, and the number of characters that need to be printed.
Laser coders can provide better overall print quality of text and logos, while small characters can only print lower resolution inks. Laser coders installed in packaging lines also benefit from longer print times and stationary eggs.
Laser-coded eggs have the most durable code quality, however small characters can use a long-lasting food-grade ink to create a very long-lasting image on the egg.
