Valmet IQ Softness Measurement (Suavidad)

Correlates to hand-feel test and lab devices such

as Emtec Tissue Softness Analyzer

Also measures other tissue surface properties

– Crepe count / cm, crepe amplitude and shape

– Known roughness measures

Tissue surface illuminated by RGB lights, each

directed from a different angle

Advanced image processing and modeling of the

captured image reveal softness and other tissue

surface properties
