Abstract
A gravure printing roll that enables printing of fine dots with a size close to that of cells and enables printing on a print subject, such as a printing substrate, without changing the appearance of the print subject. The gravure printing roll includes: a gravure printing roll body; and cells formed in a peripheral surface of the gravure printing roll body. Each of the cells has an opening with a ratio between a dimension in a circumferential direction of the gravure printing roll body and a dimension in an axial center direction of the gravure printing roll body (dimension in the circumferential direction/dimension in the axial center direction) being 1.15 to 7, and have an opening area of 3900 μm2 or smaller.
Claims4
A gravure printing roll comprising:
- a gravure printing roll body;
- and
- cells formed in a peripheral surface of the gravure printing roll body, the cells each having an opening with a ratio between a dimension in a circumferential direction of the gravure printing roll body and a dimension in an axial center direction of the gravure printing roll body, dimension in the circumferential direction/dimension in the axial center direction, being 1.16 to 5.27, the cells each having an opening area of 675 to 3869 μm2 and a formation density of the cells in the gravure printing roll being 25 cells/mm2 or smaller.
