Grating Spectrodensitometer - Portable Print Density and Colour Meter - 45/0 Geometry - 400-700 nm

The Master Science Grating Spectrodensitometer is a hand-held instrument that reads reflectance spectra, CMYK density and Lab colour values from printed samples. It uses 45° ring illumination with 0° viewing and a concave grating over 400 to 700 nm.

It is aimed at process and quality control in printing plants, where optical density and dot gain must be checked on press sheets, and also serves film processing, textile printing and dyeing, and plastics and electronics.

Common Problems and How This Instrument Helps

How the Master Science Grating Spectrodensitometer helps on the press floor:

• Separate densitometer and colour meter: both functions in one device.
• Jobs specified under different measurement conditions: M0 to M3 modes available.
• Readings that differ between presses: low inter-instrument error.
• Small colour patches: 2 mm aperture option.
