When you need a general purpose densitometer for checking tints, and measuring ink densities, look no further than the Ihara R720 - you won' find better value or a more accurate instrument!

The R720 allows you to measure tints, to check patches on control strips for tolerances on dot gain. On press, it will enable you to set up to achieve a consistent ink densities across the  web, and to maintain those levels throughout the run. It is not limited to just the 4 standard process colours, but can be used in the same way to measure tints and maintain consistency of any colour during a press run.
