Sažetak
The colour of some samples is easily seen by naked eye, but is badly or completely wrongly evaluated by measurements. Such examples are thin layers with interference effect and liquid-crystal-based thermochromic printing ink. The directional illumination - directional viewing measurement geometries which are most frequently applied in graphic art fail completely or to a large extent and integrating sphere measurements are required to describe the effect by colorimetry. Various parameters of a selected measuring geometry are also important. The consequences of using integrating sphere with different diameter and sample openings on the derived colour were investigated. The investigated samples include directional-occurring phenomena and those which are directionally independent. This is clearly revealed in colorimetric results. When the samples are observed by naked eye, we often have to change illuminationviewing conditions to get the best vision. Thus, measuring conditions should be of large importance.
