Continuous Ink Jet (CIJ) printers are the most flexible, highest speed printing available for manufacturing today. For many years this technology has been used for applying date and lot codes on a variety of products.
This method is commonly used with industrial-use printers.
Continuous inkjet printers are capable of printing on a wide variety of targets such as metals, resins, and glasses. In addition to being able to print on materials such as paper and cardboard, the quick-drying ink enables printing on materials that do not absorb ink well. Continuous inkjet printers are used in a wide range of industries such as food, medicine, cosmetics, electronics, semiconductor, automotive, and metals.
The need for traceability is well recognized in the automotive industry. Due to recent progress in the common use of components, this printing method is seeing increased use in applications where the printing of identification numbers is necessary to prevent assembly errors.
The non-contact method is optimal because the parts are easily damaged by contact. Also, continuous types can print lot numbers, which helpful in the consumer electronics industry in order to track a component’s manufacturing history.
For food safety, it is necessary to accurately print manufacturing dates and best before dates.
To prevent printing mistakes and non-printed sections, there has been an increase in the installation of inspection systems using image sensors and the implementation of similar countermeasures.
