Paper stock could be situated in a cooled environment seasonally and/or regionally otherwise it is stored in a controlled warehouse. In this paper, printing problems on a cooled paper are investigated and characterized in terms of paper properties. For this purpose, various kinds of sample are cooled down under a specially designed freezing device and printed for observing their printability. Causes for poor ink transfer on a cooled paper are suggested due to condensation, surface inactivity, and rheological change in ink film. Paperboards with higher amount of binder, thick and/or multi-coated layers are more vulnerable to poor ink trap. Severe drying of wet coating could cause a similar result as that of the coatings with higher binder formulation. It is shown that more absorptive porous structure is desirable for better ink receptivity in a cooled status. Printing on a dampened surface may be an indicator for ink transferability on a cooled paper. Finally, desirable directions for papermaker and printshop are suggested.
