Dynamic of Capillarity
Measuring principle
- Indirect determination of the dynamics by ultrasonic transmission measurement emcoDPM via air elimination by penetrating monopolar liquid into the cavities of the paper.
- By sample preparation on a carrier, one-sided or two-sided liquid contact is possible.
- Measurements with monopolar liquids, standardised n-heptane.
- Fibrillation of the fibre wall (refining) becomes visible.
Measurements and results
- emco1 (tStart) to emco7 (tEnd) of page 1 and 2 in the printing process-relevant period (tStart to tEnd), which is chosen according to the print technique
Significance for the printing process
- Ink absorption
- Ink drying
- Ink anchorage
- Ink construction
- Colour impression, gloss
- Intensity range of printing speed
- Sideness (differences between side 1 and side 2)
- Printing phenomena: smudging, depositing, block up, agglutinate, doubling, ghosting, hardening
