Innventia has recently invested in a Print Simulation Tester, PST, from Fibro System. With this instrument, it is possible to study the surface structure of samples during compression, which occurs in contact printing. If the contact between paper and printing cylinder is poor, the ink will not transfer correctly, which, for example, can cause print quality problems, such as missing dots in rotogravure or uncovered areas in flexography printing.Innventia’s newly acquired FBRM, Focused Beam Reflectance Measurement, is a tool that measures the particle size (chord length) and number of particles (counts per second) in a suspension, creating improved opportunities for advanced retention and solubility trials.The instrument is useful for a number of Innventia’s research projects and can be used in both lab experiments and on-line on paper machines. Possible applications include studying the formation of (problematic) precipitates, as well organic as inorganic. It can also be used in various types of retention tests.
