In today’s pressroom, automation isn’t just about speed, it’s about giving operators tools that make quality control faster, more reliable, and less stressful. That’s exactly why we’re excited about the new LithoScan PDF system, now available in North America.
LithoScan PDF brings together AI-powered defect detection and high-resolution scanning to eliminate guesswork, avoiding false positives, and keeping presses running. After months of testing and refinement, systems are now live and performing exactly as designed: consistently, intelligently, and operator-friendly.
The Problem With Traditional Defect Detection
Many systems overwhelm operators by flagging 50, 60, even 100 “defects” on a single sheet. The reality?
A huge percentage of them are harmless:
-
Fibers in the paper
-
Slight registration fluctuations
-
Artifacts that don’t impact the final product
Operators end up spending 20–30 minutes sorting through false positives, when what they really need is a tool that helps them focus on preventing meaningful defects.
And when a system becomes “too noisy,” it simply stops getting used.
LithoScan PDF Solves the Real Problem: False Positives
LithoScan PDF uses built-in AI technology to continually learn what is, and isn’t, a true production defect.
Instead of showing every microscopic variation, the software intelligently narrows detection down to roughly 15–20 real, actionable issues on a sheet. Over time, the system learns your work, your substrates, and your recurring non-issues and eliminates them from future scans.
That means operators spend minutes instead of half an hour reviewing defects, while still improving quality and consistency.
The Accuracy of Laser-Guided Defect Location
One of the standout upgrades is LithoScan’s laser-assisted error locator.
When a defect is found, the system physically indicates where it is on the sheet. The operator can review it, acknowledge it, and, if it’s a common, harmless mark, train the AI to ignore similar findings in the future.
Over the course of a run, that means:
-
Fewer interruptions
-
Fewer rescans
-
Cleaner, more reliable defect data
And best of all, more time printing.
Built for Operators & Modern Pressrooms.
LithoScan PDF was developed with a clear goal: make defect detection fast, simple, and useful on every shift.
Key capabilities include:
-
100% exline inspection
-
Instant sheet-to-sheet comparison
-
PDF and reference image comparison (TIFF/PNG/BMP, CMYK or RGB)
-
Real-time adjustable error thresholds
-
High-resolution RGB line camera with balanced LED illumination
-
ICC-profiled scanning for precise color evaluation
-
Extensive job-level defect logging and reporting
LithoScan PDF can even connect up to five presses, making it ideal for multi-press environments where quality needs to be consistent across production.
Designed for Demanding Markets, Including Pharma
The LithoScan series is also suitable for pharmaceutical and regulated packaging applications, where traceability and documentation are critical.
Every defect event is logged, and PDF reports are automatically generated per press and per job, supporting quality audits and compliance workflows.
Optional Upgrades for Even Greater Capability
LithoScan PDF grows with your operation. Available enhancements include:
-
Laser-assisted defect locator (highly recommended)
-
Spectral measurement reporting
-
Individual paper calibration
-
Hotfolder automation for pre-rendering PDFs
-
Multi-up nested PDF checking
This flexibility allows printers to configure a system tailored to their production mix, whether the focus is speed, compliance, or ultra-high image accuracy.
