Define the web and defect
Document material structure, transparency or opacity, width, speed, surface condition, and known good, borderline, and reject events.
Continuous production inspection
Add visual inspection to the moving web
Start with your material, examples of the defects you need to find, line conditions and measurement goals. Those details determine the camera and scanner configuration.
Present the moving web
Confirm passline, stability, tension, flutter, inspection location, access, environment, and how the defect appears under realistic conditions.
Configure vision and measurement
Confirm the SHF3 VI visual-inspection configuration and select any application-specific web measurement that must be coordinated with it.
Define evidence and response
Specify the required event review, data, alarms, communications, reporting, marking, rejection, or process response for the complete system.
Published defect examples
Test detection of your defects on representative web samples
Scantech lists the following SHF3 VI application examples. Sample testing confirms which defects can be detected on your material and line.
Contamination
- Contamination
- Dirt
- Insects
- Oil splashes
Localized material events
- Burn dots
- Gels
- Holes
Surface and formation
- Scratches
- Streaks
- Wrinkles
Optical condition
- Opacity
- Condensation
Detectability must be qualified for the real material and line
Detection depends on the defect size and contrast, material transparency, lighting, surface texture, reflectivity, web motion, camera setup and pass/fail criteria. Application testing establishes suitable detection limits and operating speed for your material; these limits are not the same for every application.
FlexScan / TREX event review
Review detected events in production context
The representative software view shows how detected events can be placed within the production history. Select a plotted event to review the available position, timing, size, category, type, and event-image information associated with that detection.
- See detected events distributed by web position and production length
- Select an individual event to open its recorded details
- Review displayed fields such as X position, time position, metering position, size, category, and type
- Use the selected-event image area to support operator and quality review
Available fields, event categories, image handling, communications, alarms, and response functions are confirmed for the quoted software and system configuration.

See visual defects and web measurement together
SHF3 VI is designed to combine classic measurements and visual inspection. The measurement technology is selected for the actual material and production objective; it is not automatically identical in every frame.
What happened on the visible web surface?
- Is there contamination, a gel, hole, scratch, streak, wrinkle, opacity event, or another visible anomaly?
- How should detected events be displayed and reviewed?
- What evidence must operators or quality teams retain and review?
- What alarm or downstream action should the complete system support?
What changed in thickness, weight, density, or profile?
- Is the selected measurement inside the target and tolerance?
- Is the cross-web or machine-direction trend changing?
- Did the process create both a dimensional and a visual consequence?
- Should the measurement support manual correction, reporting, or compatible automatic control?
Need thickness, basis-weight, density, or cross-web profile measurement?

Preliminary application fit
Where SHF3 VI is a strong starting point
Use this as an initial routing guide. The actual material, defect library, speed, environment, camera configuration, and measurement requirements determine the final recommendation.
Continuous web with a defined visual defect risk
- Cast film and sheet, coating film, biax or MDO film, or battery-separator film
- Defects create visible contrast or appearance changes
- Transparent or opaque material
- Continuous inspection adds value beyond roll sampling alone
- Visual inspection and web measurement should share a coordinated frame design
Optically or mechanically demanding applications
- Very small, low-contrast, intermittent, or acceptance-critical events
- Reflective, textured, printed, multilayer, or otherwise unusual surfaces
- High speed, web flutter, harsh temperature, dust, vapor, or restricted access
- Requirements for classification, image retention, marking, rejection, or process action
- Unclear distinction between a visual defect and a dimensional/profile problem

Scantech SHF3 VI web inspection FAQ
These answers provide a starting point. Current manufacturer data, line review, and representative materials govern the final configuration.
What does the Scantech SHF3 VI inspect?
SHF3 VI is a continuous-web scanner design that combines visual inspection with classic measurement technologies selected for the application. Scantech identifies use cases including film, sheet, coated films, biax film, and battery-separator film.
Can SHF3 VI inspect transparent and opaque webs?
Scantech states that its optical imaging can detect visual defects on transparent and opaque materials. Actual performance still depends on material response, contrast, surface, lighting, speed, defect size, and the configured system.
What types of web defects can it detect?
Scantech publishes examples including burn dots, condensation, contamination, dirt, gels, holes, insects, oil splashes, opacity, scratches, streaks, and wrinkles. These are examples, not guaranteed limits for every material or speed.
Is SHF3 VI automatically a thickness or basis-weight gauge?
Not every frame has an identical measurement configuration. SHF3 VI is designed to combine visual inspection with classic measurements, but the measurement head and outputs must be selected for the actual material, structure, range, and process goal.
Where are the visual-inspection cameras installed?
Scantech states that the defect-detection cameras are located inside the scanner-frame beams. Final camera, lighting, coverage, access, and environmental details are confirmed for the application.
How wide a web can SHF3 VI accommodate?
The current English Scantech product page lists product widths from 500 to 13,500 mm in 500 mm increments. Confirm the current available width, overall frame, access, and transport requirements in the quotation.
Does visual inspection replace laboratory or manual QA?
No. Continuous vision adds in-line inspection information, but it does not replace the manufacturer’s validation, challenge samples, acceptance rules, reference methods, false-accept and false-reject controls, or procedure for accepting or rejecting product.
Can the system trigger alarms, marking, or rejection?
Those functions must be defined as complete-system requirements and confirmed with Scantech. Public product information does not establish one universal alarm, marking, rejection, classification, or plant-integration configuration for every SHF3 VI application.
