Opacity For the product the opacity of the paper is important as well. It is in general the ability of the paper to absorb light. It is significant when printing on both sides of the paper.This means that the print image of the front side does not show through the reverse side. During the paper production you have influence on the opacity of the paper. A high opacity of paper is achieved both by the addition of fillers such as kaolin, talcum, or titanium dioxide as well as by using a greater proportion of woodground pulp.
