Abstract
A porous, roll-grinding tool has an abrasive surface which is adapted to contact and grind the surface of a roll and configured to a planar polygonal shape having 4 to 20 sides. Using the grinding tool, a roll can be ground within a satisfactory dimensional tolerance, with feed marks crossing the circumferential direction of the roll at a small feed mark pitch inclination angle, so that no streaky printing defects will be produced when the ground roll is used in printing.
