New TAPPI Brightness Calibration Standards Format

For over 50 years, TAPPI optical calibration has been performed using small 1.5 inch X 2 inch paper 'tabs'.  Technidyne is issuing a new format that will consist of a tablet which is easier to handle and will provide more consistent data since the measurements will come from the same sheet of paper. In past, it was possible that the tabs were each from a different sheet of paper.

Technidyne customers who subscribe to TAPPI brightness and/or color standards will be receiving standards in this new format in March 2015.  

Here are links to two videos showing the use of the new calibration standards with the

When using the new standards format it is important that the standards not be dragged or slid across the instrument sample plate and aperture. This can damage the surface of the standards.


Please let us know if you have comments or ideas on how these will be best implemented. Contact our Lab Manager, Nick Riggs.
