EFFECT OF INK TYPE AND AGING ON INK DETACHMENT OF NEWSPRINTS
The detachment capability of two offset coldset newsprint inks with different carrier components, mineral oil and vegetable oil, were investigated under both non-aged and aged conditions. Mineral oil based ink is found more difficult to detach than vegetable oil based ink. However, the different effect on ink detachment of these inks becomes insignificant on aged samples. This is because under the exposure of heat, the oils cross-link to the substrate generating similar cohesiveness/bond strength on the samples, and hence similar ink detachment outcomes. Due to this reason, the effect of shear force becomes more influential than prolonged treatment time on the detachment of the aged newsprint.
