Abstract
A new method is proposed to increase the print density of
inkjet prints by application of a layer of
nano-fibrillated cellulose (NFC) to the base sheet of an
uncoated woodfree fine paper treated with AKD. The
hydrophilic NFC surface holds the inkjet pigments at the
surface while the AKD acts as a barrier to liquid
penetration. A combination of NFC and AKD gave higher
print densities and at the same time reduced
print-through compared to papers treated with AKD only.
CLSM images confirm that ink spreading on and penetration
in untreated samples is greater than the AKD samples. For
the untreated samples, the ink covered the paper surface
almost uniformly with a few areas where the ink did not
cover. For the AKD samples, the ink droplets contracted
on the hydrophobic surface, giving poor coverage as shown
by the large number of uncovered areas
