Abstract
A printing plate roller including a cylindrical tube and two journaled end caps plugging opened ends of the cylindrical tube, thereby forming a vacuum chamber within the tube. At least one groove is formed in the outer surface of the cylindrical tube with at least one bore hole formed through the wall of the tube interconnecting the at least one groove with the vacuum chamber. It is desirable for a plurality of such grooves to be formed in the outer surface of the cylindrical tube. The vacuum chamber is connectable to a vacuum producing source.
