High Resolution Surface Topography measurement

Paper surface roughness plays a crucial role for printability and visual appearance. Several types of instruments are available topography measurements of paper surfaces in different degrees of detail. The FRT MicroProf instrument…

Measurement of print-through

Print-through is an unwanted effect when you see some of the ink from the opposite side of a paper in a magazine. It is a combination of the show-through (=effect from opacity) and the strike-through (=effect from ink penetration)…

Surface roughness measurement using OptiTopo technique

The unique OptiTopo technique used for print prediction quickly reveals the correlation between paper surface and print defects such as uncovered area or missing dots
Service

Missing dots measurement

The problem of missing dots occurs especially in gravure printing. Quantifying the amount of missing dots using the right tools allows you to monitor the problem to see if the if the print quality is acceptable.

Optical formation measurement

Optical formation is the variation you see when looking through a paper illuminated from the back side. Fibre flocks of different sizes and shapes can be seen as well as wire marks. For coated paper qualities the coating can reduc…
