How High-Speed CIJ Printing Increases Units Coded Per Hour

In today's fast-moving manufacturing environment, every second on the production line counts. From food packaging to pharmaceuticals, the efficiency and accuracy of your coding system significantly affect your production. For manufacturers who need to get the most units coded per hour without sacrificing print quality or printing uptime, High-speed Continuous Inkjet (CIJ) printing is the solution they have turned to. However, how does it do this, and how does it differ from other coding technologies? Let’s get an idea about that in detail.

How Does High-Speed CIJ Printing Improve Production Efficiency?

High-speed Continuous Inkjet (CIJ) printing improves production efficiency by applying variable data (e.g., batch codes, expiry dates, and barcodes) at rates of up to 1,000 units per minute. Because the non-contact printhead never touches the product, manufacturers can operate at top rates without any delay in production. Here are five key ways high-speed CIJ printing helps increase units coded per hour and improve overall production efficiency.

Exceptional Print Speed at Line Speed

The CIJ printers are designed to produce speeds of more than 1,000 feet per minute in many industrial applications. This allows the printer to operate at the same speed as the fast-moving conveyor without the need for a slowdown in the manufacturing line. The outcome is an immediate and quantifiable rise in Units Coded per Hour, with no "throttling" by the Coding Station.

Minimal Downtime Through Continuous Operation

As one of the biggest productivity benefits of CIJ, it can operate without a lot of downtime. A solvent-based ink system enables automatic printing head cleaning, which eliminates cleaning between shifts. Many modern CIJ printers also have a function for the auto-flush and auto-startup of the printer, so an operator has less time to spend on maintenance and more time running the product. When your downtime is cut, so are your units that are not being coded, which is a crucial metric in high-volume production.

Fast Changeover and Code Flexibility

High-speed CIJ printers have the capability of providing instant message switching through easy-to-use touch screen interfaces or through plant-wide MES/ERP systems. No halt to the line or change of equipment required as new code is queued up and applied smoothly. This agility alleviates one of the major challenges for multi-SKU operations, allowing manufacturers to have high throughputs even when frequently changing between Stock Keeping Units.

High First-Pass Print Quality

The low-quality print leads to rejections, rework, and manual re-coding, and all of these have an impact on productivity. The CIJ technology provides clear codes that can be achieved on irregular or porous surfaces. Printing high resolution at speed guarantees that barcodes, date codes, and lot numbers can be scanned and are still compliant the first time, eliminating downstream quality failures from pulling units off the line.

Integration with Automated Production Lines

Modern CIJ printers come with built-in integration to an automated production environment. They can connect to standard communication protocols like Ethernet, RS-232, and OPC-UA, allowing for centralized control and real-time monitoring. No manual triggers and no human delays, automated line integration checks that each product is coded at the correct time and that there are no gaps or repeats.

Ready to Improve Your Coding Efficiency?

The selection of the right coding technology is a production decision. High-speed CIJ printing from a trusted brand like Astropack boosts the number of units coded per hour by keeping pace with high-speed production lines. It also reduces downtime through automated maintenance, enables fast code changeovers, delivers consistent first-pass print quality, and integrates seamlessly with modern automated production lines.

CIJ printing is more than a coding solution; it is a production efficiency tool for manufacturers facing pressure to reduce their time to market and continue to maintain compliance.
