Techkon RS 400 Scan Densitometer – fully tested, ready for real production work.

Professional scan densitometer designed for precise print quality control in offset and flexo environments.

💡 Why Scan is Better than Spot Measurement

Unlike single-point (spot) measurements, the RS 400 scans the entire control strip in one pass.
This gives a full picture of print consistency across the sheet — not just one point.

It helps detect variations, ink imbalance, and stability issues much faster, making it a more efficient and reliable tool for real production environments.
