Abstract
An emboss device (1) includes an emboss roller (21) having a surface on which protrusions and recesses are formed, and a press roller (20) arranged oppositely to the emboss roller (21), wherein a print object (100) is held between these rollers and imparted with protrusions and recesses. Surface of the emboss roller (21) has an arithmetic mean roughness Ra of 4.50-18.55 μm and kurtosis Rku of 2.12-3.88. Uneven surface of the print object (100) has an arithmetic mean roughness Ra of 0.55 μm or above and skewness Rsk of −2.73 to −0.65.
Claims5
An emboss device, comprising:
- an emboss roller having a surface on which protrusions and recesses are formed;
- and
- a press roller arranged oppositely to the emboss roller, wherein a sheet-like print object is held between the emboss roller and the press roller and is imparted with protrusions and recesses, and
- the surface of the emboss roller has an arithmetic mean roughness Ra defined in JIS B0601:2001 standard of 4.50 to 18.55 μm and kurtosis Rku defined in the same standard of 2.12 to 3.88.
A print object having an uneven surface imparted with protrusions and recesses on a side of the print object on which image has been thermally transferred, wherein
- the uneven surface of the print object has an arithmetic mean roughness Ra defined in JIS B0601:2001 standard of 0.55 μm or greater and skewness Rsk defined in the same standard of −2.73 to −0.65.
