Vision Systems for Glass Screen Printing
Screen PrintingIntegrated vision systems for automated glass screen printing, providing print inspection, screen registration, ink detection and process quality control.
Specifications
- Glass Quality Vision System – GQVS
- Installed after the glass washing machine, GQVS scans the complete glass surface. Detects: Scratches Breakages Air bubbles Chips Contamination Water residues Other surface defects It's suitable for raw, cut or ground glass. Individual sensitivity levels can be set for different defect types and different areas of the glass.
- Print Quality Vision System – PQVS
- Installed immediately after the printing machine, PQVS automatically inspects the printed image. Detects: Smearing Widening of printed details Pinholes Faded dots Missing elements Print defects High-resolution linear cameras inspect fine print details against predefined tolerances stored within the inspection recipe. Importantly, the system can provide feedback allowing automatic correction of the screen-frame position without stopping the conveyor.

Importantly, the system can provide feedback allowing automatic correction of the screen-frame position without stopping the conveyor.
- Automatic Screen Registration – ASR
- Uses two cameras positioned beneath the printing table together with servo-controlled positioning to automatically align the screen with the glass. Alignment settings are stored within the production recipe, reducing setup time and making product changeovers faster and more repeatable.
- Broken Screen Detection – BSD
- Automatically detects ink leaking through a damaged screen onto the underside of the glass. A dedicated camera monitors ink transferred onto a white reference roller. Cugher states that the system can identify ink spots as small as 1 mm in diameter, regardless of their position on the glass.
- Ink Detection System – IDS
- Detects unwanted ink residues on the lower surface of the glass before they contaminate conveyors or cause subsequent production defects. Linear cameras and dedicated lighting inspect a white reference roller, with the results processed in real time and communicated directly to the PLC.
- Broken Edges Detector – BED
- Inspects the edges and corners of the glass before critical operations such as printing, bending or tempering. The system automatically adapts to different glass formats and provides real-time defect visualisation and communication with the production-line PLC.

About the Vision Systems for Glass Screen Printing
The Cugher Vision Systems for Glass Screen Printing provide integrated vision technology for the automatic control, inspection and optimisation of industrial glass screen printing processes.
Using advanced cameras, lighting and dedicated software, Cugher Vision Systems can monitor the printed image, screen position, ink contamination and glass condition at critical stages of the printing process, providing real-time information directly to the production line control system.
The range includes specialised solutions for print quality inspection, automatic screen registration, broken-screen detection and unwanted ink detection, helping manufacturers maintain consistent print quality while reducing manual inspection and operator intervention.
Inspection parameters and sensitivity levels can be configured according to the individual product and production recipe. Critical areas such as logos, barcodes and detailed printed sections can be inspected using specific tolerances according to the required quality standard.
Cugher's vision technology can also communicate directly with the screen printing machine and line automation. Depending on the system, inspection results can be used not only to identify defects but also to automatically correct screen positioning, helping maintain production accuracy without unnecessary line stoppages.
Additional Cugher vision technologies are available for checking glass condition and damaged edges before critical production processes, allowing the complete printing line to be monitored and automated according to the application.
Integrated directly into Cugher screen printing and automated production lines, these systems help improve print consistency, reduce waste, simplify setup and provide greater control over the complete printing process.
Stone & Glass Group supplies Cugher screen printing machinery, vision technology and complete automated production systems throughout the United Kingdom, Ireland and Benelux, including specification, installation, commissioning, training, servicing and technical support.
