Abstract
The printing offset blanket in accordance with the present invention has a surface printing layer made of a mixture of silicone rubber and oil-resisting rubber. It is therefore possible to prepare ink layers having a uniform thickness and clear edges. Further, the present offset blanket can be improved in paper discharging properties and retention of paper powder, enabling the blanket to be suitably applied to high-speed printing, filter or display prints, or the like. The printing rubber roll of the present invention is made of a mixture of silicone rubber and oil-resisting rubber. Accordingly, the present rubber roll is excellent in stability with respect to ultraviolet-curing ink and can therefore be used for a long period of time.
