What is the working principle of ALE high-resolution systems?
The technology of ALE high-resolution printers is known as PIEZOELECTRIC (or piezo), part of the Drop-on-Demand (DOD) range of inkjet technologies.
When voltage is applied, two pieces of piezoelectric material (in our case ceramic plates) change shape, generating some pressure on the fluid that is then expelled out of the print head onto the surface. It defers from TIJ (another DOD technology) as there is no heating system to propel the ink and, therefore no need to use highly volatile inks as solvent-based or aqueous-based ones.
Piezoelectric DOD systems offer long service life with minimum maintenance, high speed of application and low operating costs.
What applications are recommended for High-resolution coding?
Traditionally, High-resolution inkjet technology have been used for end-of-the-line packaging, to mark onto porous carton boxes directly as they pass on the production lines.
Thanks to the recent innovations in the inkjet industry, and thanks to its extensive experience in High-Resolution coding, ALE has developed systems that can respond coding and marking needs across the industries.
How big can I print?
ALE offers a wide range of print heights, from 18mm to 72mm, and even 144mm systems (the biggest print height available on the market) with a single controller. One controller can also manage up to 576mm of printing height (8 x 72mm) which is another exceptional feature on the market.
ALE printers are also available in solvent-based inks. Are they harmful? Do they require lot of intervention?
Contrary to traditional CIJ and large characters DOD printers using high volatile MEK solvent-based inks, ALE relies on low volatile dye-solvent based inks. All our fluids are REACH approved, meaning that they represent no threat to humans or environment, and they are also 100% recyclable.
Given the fact that the solvent tends to evaporate less rapidly, the open time ( period during which the printer can be left without printing) is greater and, when not used for more than 30 minutes, either a simple prime or a mere wipe of the head with some solvent gets the full printing capacity of the printer back.
Omnidirectional systems of ALE allow moving-head applications: is there risk of ink spill or leakage?
On ALE high-resolution coding and marking systems, the hydraulic system (including the ink reservoir) is completely separated from the omnidirectional print head. In moving-head applications, the print engine is placed onto a moving device but the hydraulic system remains still so there is no risk of spill or leakage that can dirty the line or damage the code.
What is the code rating obtained with piezo High- Resolution technology?
Barcode grade takes into account many different factors, including contrast and edge precision and is therefore substrate dependent.
With ALE high-resolution printers you can obtain a grade A code on white substrate and codes between B and C grades on brown cardboard for instance. Darkness and density can be both adjusted, as well as other features, directly from CodeX Design software (lien), to improve code accuracy and readability.
How can I know the final result on my product?
ALE is happy to help you determine the best option for your specific applications and we know that the safest and most accurate way to know which solution is more appropriate is too see the final result on your product. That is why ALE offers a service to print free samples on your products.
