INFLUENCE OF THE OFFSET RUBBER BLANKETS COMPOSITION ON THE SCREEN ELEMENTS REPRODUCTION PRINTED ON DIFFERENT PAPERS

The quality of the printed screen elements made by the application of two types of offset rubber blankets (ORB) have been investigated in this work. The force in the contact zone between the offset cylinder (ORB) and the printing cylinder (printing substrate) is decisive for making the prints. With the different structure of ORB the different deformation zone is created, which results in forming the different sizes of the screen elements. The printing substrate has also influence, and because of that 5 characteristic papers (fine art paper gloss, fine art paper mat, offset paper, calendered offset paper and recycled paper) have been analyzed. The results show that on the tested printing substrates, the both ORBs form the greatest dot gains in the following order: offset paper, recycled paper, calendered offset paper, fine art paper mat and fine art paper gloss. Such results are completely in accordance with the original roughness of paper.
