Find Your High-Performance Bucket Printing Machine
120 LPI print accuracy — crisp dots, stable output.
Maximum printing speed: up to 200 pcs/min for standard buckets and 100 pcs/min for handled buckets.
You can integrate positioning, feeding, unloading, vision inspection and robotic handling for your factory
You can reduce operating costs while maintaining high production efficiency.
Real-time defect detection with automatic rejection for stable printing quality.
Flexible modules adapt to new products and future automation upgrades.
Printing Handled Buckets with Greater Control
CAI’s handled-bucket solution keeps the handles in a controlled orientation during feeding, helping prevent them from interfering with the printing area. During pail output, handle orientation is random, so we employ an intelligent robotic sorting system that aligns all handles uniformly before stacking and collection.
Maintain Precision Across Large Bucket Formats
To ensure consistent print quality, CAI applies strict component control and precision assembly standards. Aluminum rollers are inspected by CMM at room temperature, while the 1.8-meter printing gear features less than 0.03 mm runout, ensuring stable movement and accurate registration.

Leading Dry Offset Solution Provider in China
When you choose CAI, you get more than a machine — you get our know-how. We’ve spent years designing, building and running bucket printing lines in real factories, so our engineers know printing, positioning, automation and material handling inside out, and they’ll work with your buckets instead of forcing a one-size-fits-all setup. We’re with you from start to finish: first we help you pick the right configuration, then we install it, train your team, and keep spare parts and technical support ready whenever you need them — for as long as the machine runs, we’re just a callaway.
Global Printing Cases for CAI Bucket Printing Machine
A U.S. customer chose CAI’s 8-station bucket printing machine for printing PP flower pots. The machine uses flame treatment to improve ink adhesion and a conventional feeding and unloading system, as the pots do not have handles. The machine is currently running stably, delivering consistent printing quality for the customer’s production.
A Russian customer chose CAI’s handled bucket printing machine with precision positioning and inline vision inspection. The machine handles 7 different bucket sizes, from 2 to 16 gallons, including buckets with both plastic and metal handles. It currently runs at 50 buckets per minute, delivering stable performance and consistent print quality across different formats.
Customer from Worldwide
The machine has been running stably and delivers consistent printing quality on our PP flower pots. The flame treatment works well for our application.
U.S. Flower Pot CustomerThe machine handles our 7 bucket sizes and both plastic and metal handles very well. The positioning and vision inspection systems make production more stable and reliable.

The machine is equipped with 8 ink stations and has a net weight of approximately 15,000 kg. The main machine measures 3,700 mm (L) × 4,700 mm (W) × 3,600 mm (H).
You can print buckets with a maximum height of 400 mm, a diameter of 130–380 mm, and a taper angle of 0–12°. The machine configuration can be customized according to your bucket dimensions, shape and printing requirements.
You can achieve a maximum printing length of 650 mm with 6 printing blankets. With 3 blankets, the printing length can reach 890 mm, but the printing speed is reduced by half. With the optional magnetic plate configuration, the maximum printing length can reach 920 mm.
Yes. You can print buckets with both plastic and metal handles with simple setup adjustments. We can design the positioning solution according to your requirements, as different positioning components are typically used for plastic and metal handles.
During feeding, a dedicated positioning device keeps the handles in a consistent direction and prevents them from interfering with the printing area. After printing, a robotic positioning system aligns the handles in the same direction before stacking, ensuring consistent handling throughout the process.
A magnetic printing plate can significantly reduce the amount of plate material you need, especially for buckets with long printing areas. This makes it a cost-effective option for long-term production.
It also makes plate changes faster and easier through magnetic positioning. In addition, the magnetic plate configuration provides a longer maximum printing length, giving you greater flexibility for different printing requirements.
