Test/Plus TAPPI Brightness Tester

The Test/Plus TAPPI Brightness Tester combines industry standardized measurement technology with an innovative control package that allows the user to tailor build their testing and evaluation capabilities. This new addition to the TEST/PlusTM product line is built to meet your TAPPI Brightness testing needs.

Optimizing your processes is the goal of any manufacturing environment. This Paper Brightness Tester provides a tool for the effective evaluation of your processes. Once accurate evaluations are established, then process control parameters can be set. The TEST/ PlusTM TAPPI Brightness can be counted on to be that repeatable evaluation tool to help you optimize your system. When the process has to be right, you need the right tools. With the TEST/PlusTMTAPPI Brightness, you can make it right the first time.

At the core of the TEST/PlusTM, TAPPI Brightness is a series of specially developed APPS that allow for complete control of your data and how you interface with the instrument and your operation.

About TAPPI T452 Testing Standard

TAPPI T 452 om-18helps determine the brightness of white, near-white, and naturally coloured pulp, paper, and paperboard. Brightness is a commonly used industry term for the numerical value of the reflectance factor of a sample with respect to blue light of specific spectral and geometric characteristics. This method requires an instrument employing 45° illumination and 0° viewing geometry with the illuminating and viewing beams adjusted so that translucent materials are evaluated on an arbitrary but specific scale. The cone of light (see A.3.2 and A.3.5) used by this method is wider than that specified for the CIE Standard 45/0 geometry.

Brightness and whiteness are not the same measurements. Brightness and whiteness are not interchangeable, and there is no known mathematical relationship between the two values.

This procedure is applicable to all naturally-colored pulps, and papers and board made therefrom and is suitable for optically brightened pulp and paper. The measurement is not suitable for paper or paperboard containing added coloring matter (such as yellow or green dyestuff) which appreciably absorbs light in that part of the spectrum extending from about 400 to 500 nm. This brightness method is not applicable to colored papers which must be measured either spectrophotometrically or colorimetrically in order to obtain meaningful results
