The printing process relevant characteristics of paper
4. Absorbency (emcoDPM print)
1. Characteristic: Absorbency
2.
Measuring principle: indirect determination of the characteristic
ultrasound-transmission-measurement emcoDPM after dynamic contact of one paper side with distilled water.
3. Measurements and results
emco1 (td) to emco7 (td) from side 1 and 2 in the printing process relevant period D.
Measurements with additives, impregnating resin, sodium silicate and other liquids are possible.
4. Significance for the printing process
Dynamics of the additive absorbency
Print speed range
Sideness (differences between side 1 and side 2)
Water resistance of the surface
Conclusions if it is capillary penetration or fibre absorption
