Densitometry measurement

Colorimetric devices

3-color colorimetric devices - identification of colored patches location

Spectrophotometers do not contribute additional relevant information and have drawbacks

Ignoring irrelevant changes (i.e. randomly occurring artifacts)

Many pixels per each color-bar patch

2x2 mm patch

Trend analysis

Non sampling device (100% control)

Every sheet monitoring in full width

Multi-purpose device

One sensor - many applications

In one device:

• - Color control
• - Color registration
• - Dot-Gain analysis
• - Image quality inspection
• - Image viewing

Dot gain analysis in half tones.

Controlling several tones (Full tones and Half tones). Use of many small patches on color-bar

Full tone, Mid-Tone and additional tones (25% & 50%) are possible. 2x2 mm patches are achievable

Slim color-bars

2 mm color-bars

2 mm color-bars

High speed

Up to 18,000 sheets per hour
