Quality Control

BOBST ACCUCHECK system is fully and seamlessly integrated in the DIGITAL MASTER 340 and DIGITAL MASTER 510, delivering automatic calibration and inspection to guarantee: 

• Waste reduction
• Productivity increase
• Full integration into press workflow 
• Zero set-up time

Converters must ensure flawless operations to prevent label defects, minimizing waste and profit loss. ACCUCHECK is BOBST’s solution to this critical challenge, simplifying quality control and guaranteeing zero-fault labels with smooth and simple operation.
ACCUCHECK offers two major functionalities in one single device, which do not require any human intervention: calibration and inspection.

Calibration automatizes all the machine setup and corrections, allowing downtime reduction through four functionalities: 

• Automatic head stitching for a perfect positioning of the cluster
• Automatic color to color calibration
• Fast and automatic densities uniformization along the width with smoother color gradients on any substrate
• Automatic detection and compensation of any bad nozzle

100% quality inspection at full speed seamlessly integrated into the press workflow ensures zero setup time and synchronizes job queues with the digital printing unit. This guarantees perfect production quality from the first to the last label, without compromise, regardless of width or speed.

• A high-performance camera detects imperfections down to 0.15 mm² at very low contrast 
• Registration is accurate with a print-to-print measurement down to 0.1 mm
• Color variation measurement down to 1 dEc is possible at full speed along the entire width, ensuring consistent and accurate results
• Automatic zoning, reading, decoding and grading of static and variable barcodes and QR codes

With BOBST ACCUCHECK system for Narrow-Mid Web Solutions, you can say goodbye to costly claims, increase productivity and profitability, reduce waste, and simplify your entire production process with an integrated system.
