When Density Alone Isn’t Enough

Measuring ink film thickness, or density, is a key quality control process in prepress and the press room. But sometimes density alone isn’t enough. The X-Rite 508 spectrodensitometer accurately measures ink density but also measures dot area and dot gain to gather more data about the quality of printed output and enable timely adjustments during makeready and production.

The 508 spectrodensitometer has a handy targeting window that enables operators to pinpoint the measurement area to quickly get the right measurement every time using one of three standard measuring areas, or use the microspot measuring area for smaller targets. Its full menu commands in multiple languages and customizable menus make it easy to use even for less skilled operators.


  • Measures any density status quickly and reliably, as well as dot area and dot gain to provide full density information for optimum stability throughout the press run.
  • Large display shows a choice of single, 3-color or 4-color density values for maximum flexibility.
  • Unique ability to select from a range of measurement apertures, including microspot (1.6x3.2mm), small (2.0mm), medium (3.4mm) or large (6.0mm).
  • Store density references and customer specifications to quickly determine whether density adjustments are required in printed output.
  • Benefit from exceptional inter-instrument agreement for accurate and repeatable color across presses, shifts and locations.

The 508 spectrodensitometer’s rugged construction can stand up to even the most challenging press room environments. It produces exceptional inter-instrument agreement with a delta E of 0.01, or 1% for typical printing processes. You can trust your 508 spectrodensitometer to give you comparable measurements among multiple presses or printing sites, with suppliers, or between the customer and the printing facility. And its rechargeable battery pack ensures optimum uptime for the instrument.
