New technologies to monitor pigment properties in the process and in the final product
As printhead and inkjet technology are progressing, the demand for characterisation of inks regarding their pigment size, single oversized grains and colloidal stability is increasing. The size of pigments has an impact on factors like printability, printhead blockages, sharpness of texture, optical density and colour gamut. Microtrac introduces a new technology which combines, for the first time, data from laser diffraction and Dynamic Image Analysis. This enables users to monitor the production process, to assess the final product and to detect single oversized particles or clumps which cause a risk for blockages. Furthermore, the 180° probe technology in Heterodyne Dynamic light scattering is an enabling technology for on-line and in-line applications to measure the size of nano-pigments and dyes directly in the process and in the final product with little dilution.
