Colorscan CIS-12

Monitoring of colour and colorimetry

Detects the slightest colour variations

The traversing colour scanning system for product inspection. The measuring system used in the Colorscan CIS is based on a spectro-photometer with a 0° / 45° geometry.

Traverse speeds of up to 1.2 m/sec can be reached. The measuring spot created in dynamic mode is approx. 18 mm wide and 60 mm long. Repeatability of the measured values is outstanding.

Product highlights

  • Traversing, noncontact spectrometer for use on a running web
  • Objective measurement of colour and degree of whiteness
  • Display of the colour values in the internationally-standard CIE Lab system

Customer benefits

  • Highest accuracy of colour measurement
  • Highest repeatability of colour measurement
  • High measurement density

No risk of  overlooking slight variations in colour

When a piece is unevenly dyed, the colour across and along it varies gradually as a rule over many metres of cloth. The human eye has great difficulty therefore in detecting such subtle variations.

Once the material has been made up into garments, even the slightest difference in shade between two pieces sewn together will create a very bad impression. The percher really has no option but to cut samples at regular intervals from the piece, and compare them.

Quality controlled colour

The Colorscan CIS solves this problem. A spectrophotometer that runs to and fro across the on-line cloth, and takes measurements at the left, centre, and right, the scanner aligning itself automatically to each selvedge. In doing so, the Colorscan CIS logs continuously any variations in shade, both across the piece, and along its length.

The Colorscan CIS compares successive colour values with, for instance, a reference measurement taken at a given point at the centre of the piece (or a manually entered target figure). It then highlights any departures from the reference measurement, or set-point, and documents any colour variations relative to piece length. A pass / fail assessment can also be issued by entering specific tolerances.
