Color is an important design and recognition factor for products and packages; it can even be the decisive factor regarding the product acceptance. The continuous and objective control of the color is an absolute prerequisite for constant quality, especially when natural or recycled materials with varying chemical compositions are used.
With the software package PRISMA and a PC-controlled photospectrometer, you can determine exactly the spectral transmittance and reflectance properties of solids and liquids, and calculate and display the Helmholtz and CIELAB/CIELUV color values.
PRISMA is available as Standard, Professional (with statistical and report functionality), Glass (with special analysis methods for glass industry) and Expert (all modules) edition. Customized packages and adaptations are also available on request.
