RHOPOINT TAMS™

An Innovative New Technology Models The Human Perception Of Surface Quality

The next generation paint quality instrument that sets new standard in appearance measurement.

Rhopoint TAMS™ is a new way of quantifying appearance quality inspired by a four-year collaboration between Rhopoint, Volkswagen AG and AUDI AG. 

The Rhopoint TAMS™ is built with an innovative new technology design models to the human perception  of surface appearance quality, providing new parameters that revolutionise the understanding and communication of visual appearance information. Individual new values for contrast, sharpness, waviness and dominant structure size fully describe the visual perception.

For maximum impact, an automotive paint finish must instantly produce an appealing visual sensation for the customer. This can only be achieved if the overall surface finish displays both high QUALITY and HARMONY.

Rhopoint TAMS™ technology provides opportunities to IMPROVE SURFACE FINISH, establish improved QUALITY CRITERIA and REMOVE SUBJECTIVITY IN VISUAL ASSESSMENT.
