Every Domino coding technology applies something physical (ink, ribbon transfer, label, etc.) to create a contrasting code on a customer’s product. Except laser.
Lasers apply “energy” and any contrast created is dependent on the material absorption and reaction to the laser energy. The understanding of how various materials absorb and react to laser energy is called Material Science.
Without a material science understanding, the laser sampling process becomes one of trial and error. Trial and error is not the right approach. There is a science to making sure the right technology codes onto the right substrate resulting in legible, accurate codes 100% of the time. How confident are you in your process today?
Domino takes the guess work out of that for you and can assist customers in recommending proper substrates, testing or setting up a process for the codeability of such materials. With the material science understanding, coding performance can be significantly enhanced.
Have you ever tried to code onto a material you have used before, and the code just doesn’t measure up? Consider this – A cardboard carton looks exactly alike when put side by side. The natural assumption is that the same coding technology and set-up would produce the same quality of code, right? When in fact, this may not be the case. Since “codeability” is not part of the specification of any cardboard material supplier, customers are then left to have to qualify their packaging materials themselves and install a Quality control process to avoid material related problems.
Material Sciences provides the basis for determining the most effective laser configuration and the optimum substrate characteristics for best coding results. This knowledge can be used to provide guidance to the customer’s material supplier on what characteristics are most important to maintain good laser codeability.
Domino uses a series of scientific tools and processes to characterize a customer’s substrate. We can scan the material to determine its unique identity and determine how much it absorbs and which laser will be most effective. The scan will also cross-reference to a database of scans of similar materials and projects.
We can create high-magnification, 3D images of the code interaction with the substrate to ensure it is creating the desired effect.
To minimize any negative influence of the substrate on code quality, the Domino sample lab has tested over 90% of the commonly used materials, and can provide guidance for material suppliers to prevent any batch-to-batch variations which could affect code quality, greatly reducing downtime.
So that being said, there is more to meets the eye and that comes in the way of testing and aligning with a supplier who understands that anyone can put a code on a product. It’s understanding the science behind the technology that result in the best code for your needs. A quick sample review with Domino can make all the difference in the world – even if you are not a Domino customer today. We can help.
We encourage you to visit Domino at our booth at Packexpo (S-2520). We will have our experts onsite to discuss Material Sciences in more detail, as well focusing on common challenges related to: Flexible Packaging, Foils, Carton Variations and lastly Serialization codes.
