Technidyne ColorTouch® PC

The ColorTouch® PC is a powerful spectrophotometer that gives you complete control over the optical properties of your paper based products.


Brought to you by Technidyne, our specialist optical, surface, and physical property testing brand, The ColorTouch® PC inspects everything from ISO brightness, color and color difference to fluorescence and opacity. 

In today’s world of strict standards and high demands, the data needed to assess whether a product meets customer specifications is essential. You can count on our industry-leading spectrophotometers when paper color decisions matter.  

Color spectrophotometer versatility 

Our industry-leading spectrophotometer is quick, exact and versatile. With swing-in calibration, primary calibration, ColorTouch PC software, sample viewing and optional equipment, its functionality is far beyond standard color evaluation. 

PC perfect spectrophotometer inspection

The ColorTouch® PC is driven by a powerful software package that provides you with the ultimate flexibility to develop and design specific operational presentations to match your testing needs.  

The simple Windows™ based interface of our ColorTouch software gives you total control over your spectrophotometer data analysis. You can use information from several different measurements and by evaluating historical trends. 

Quality spectrophotometer testing – as standard

The colortouch spectrophotometer was developed to support paper color inspection to a wide range of international standards. These include: ISO 12625-15, ISO 12625-16, ISO 12625-7, ISO 2470-1, ISO 2470-2, ISO 5631-1, ISO 5631-2, ISO 5631-3, TAPPI T519, TAPPI T525, TAPPI T527, TAPPI T534 and TAPPI T560. 

More color spectrophotometer solutions

We make a wide range of spectrophotometer devices and accessories. For example, check out the ColorTouch®X 45 which combines a powerful set of tools to meet the demands of the brightness, color, color difference and fluorescence markets. Or perhaps the PROFILE/Plus® ColorTouch, which offers unmatched capacity for appearance evaluation, is more appropriate for your workplace.  

Spectrophotometer news and views
