VARIABLE QR CODE PRINTING MACHINE PMZ-LUV1040-G

PMZ-LUV1040-G Variable Code Printing Machine – QR codes, barcodes and serial numbers on packaging sheets

Traceability, anti-counterfeiting and unit-level identification are now standard requirements for pharmaceutical, food, cosmetic and consumer goods packaging. To give every carton its own code, printers need a variable data printing step after offset printing. The PMZ-LUV1040-G variable code printing machine is an automatic sheet-fed digital inkjet system that prints codes directly on large-format printed sheets before die cutting and folder gluing.

Machine overview

The PMZ-LUV1040-G is a complete feeding – inkjet printing – curing – delivery line. It consists of a high-speed feeder, a sheet alignment table, a digital inkjet unit with Ricoh G5 piezo DoD (Drop on Demand) print heads, an LED UV curing unit, a reject unit and an automatic delivery. It handles sheets up to 1040 × 1040 mm, 90–500 g/m², at a maximum speed of 120 m/min.

The printed data changes on every sheet and at every position on the sheet: QR codes, 1D/2D barcodes, serial numbers, pharmaceutical supervision codes and promotional codes.

Applications

• Traceability QR codes and anti-counterfeiting codes on folding cartons.
• Supervision and regulatory codes on pharmaceutical packaging.
• Barcodes, serial numbers and sequential numbering on cosmetic, food and consumer goods cartons.
• Promotional and prize codes (water-based invisible ink is optional and is used with IR drying).
• Substrates: paper, coated board, PET, PVC and other sheet materials.

Key technical features

1. High-speed feeder

• Pre-stacking device, horizontally suspended feeder head and single-side adjustment mechanism for simple operation and a larger working area.
• Maintenance-free high-speed feeder head.
• Sheets can be fed in landscape or portrait orientation; minimum sheet size 350 × 350 mm.
• The standard configuration does not include non-stop feeding.

2. 1.8 m sheet alignment table

• Extra-long 1.8 m alignment table gives stable registration for both large and small sheets, with an accuracy of ±0.15 mm.
• Support strips made of special material to avoid scratching the printed surface.
• Centralized lubrication for easy maintenance.

3. Digital printing unit

• One-piece cast frame with vibration damping keeps the print head gap stable at high speed.
• Vacuum table with adjustable suction flow to suit different materials.
• Industrial Ricoh G5 print heads, drop sizes 7 / 14 / 21 pl, maximum firing frequency 30 kHz.
• Supports 1 to 8 print head groups, positioned according to the code layout on the sheet.
• Ink temperature controlled within ±1°C, with a degassing module and 3-stage ink filtration before the print head.
• One-button automatic print head cleaning with several cleaning modes.

4. LED UV curing

• LED UV lamps, 0.9 kW per lamp, cure the UV ink immediately after printing.
• Options: infrared (IR) drying for water-based invisible ink; automatic positioning of the LED UV lamp to the print head to shorten make-ready time.

5. Reject unit and delivery

• Defective sheets are rejected by a high-speed solenoid-controlled unit.
• Single-sheet or shingled delivery, with adjustable sheet count and delivery timing.
• Options: vibrating delivery, side jogging, front lay device.

6. Electrical control

• Touch screen with PLC control and centralized settings; no manual adjustment of each section.
• Industrial PC with UPS and licensed Windows operating system.
• Modular design: control, drive and ink supply systems work independently, with module self-test at start-up and fast module replacement in case of failure.
• Complies with CE safety standards.

Practical benefits for the plant

• Coding on the full sheet: codes are printed before die cutting instead of on each glued carton, reducing process steps and labour.
• Accurate code position: ±0.15 mm registration places the code exactly in the reserved window of the offset-printed design.
• Stable code readability: according to the manufacturer, more than 99% of pharmaceutical supervision codes reach grade A.
• Flexible speed and resolution: the vertical resolution is selected according to the code requirement to balance output and ink consumption.
• Less downtime: modular construction, self-locking quick connectors, and continuous monitoring of ink flow and air pressure.

Suitable customers

• Offset folding carton printers that need to add a variable data printing step.
• Printers of pharmaceutical, dietary supplement and cosmetic packaging.
• Consumer goods packaging printers with traceability, anti-counterfeiting or promotional code requirements.

Conclusion

The PMZ-LUV1040-G suits folding carton printers that need to print QR codes, barcodes and variable data directly on large-format sheets with high positional accuracy. The number of print head groups, ink type, and drying and delivery options are defined according to the product design and actual output of each plant.
