Measurement of Colour on Translucent Material Viewed by Reflection
In this paper a measurement technique is developed to measure colour printed on translucent media with reflection mode geometry with a backing material. A number of paper backing materials along with PTFE plaque tiles of 10 mm and 6 mm thickness are investigated for conformation with ISO/CD 13655 (2006) and CGATS (2001) standards for backing materials. A measurement procedure is developed using these backing materials to make measurements relative to perfect diffuser. A model is also developed to predict CIE XYZ tri-stimulus values of a colour patch to be printed on paper to match with the same colour patch printed on translucent substrate viewed by reflection with a GMG double backing proofing paper. This model is then evaluated psychophysically using a halftone print. Categorical judgement technique is used to collect visual data.
