The method for crosslinking and curing the ink may be any conventionally known method, for example, using an ultraviolet source such as a xenon lamp, a low pressure, medium pressure, high pressure, or ultra-high pressure mercury lamp. The ultraviolet rays may be irradiated in an amount sufficient to fully cure the ultraviolet curable resin ink, and are appropriately selected depending on the ink.

御することができる。When the sheet is then heated without stretching, as shown in FIG. 2, only the portion of the stretched sheet that does not have a printed pattern on its surface substantially contracts; The area does not substantially shrink due to the crosslinking and curing of the ink, thus creating a sheet with a printed pattern.
The portions are raised from the sheet surface to form an uneven pattern that is perfectly aligned with the printed pattern. −The heating temperature of the sheet is as follows:
Usually, a temperature range of 100 to 200°C is appropriate. In addition to the stretching rate of the stretched sheet described above, this heating temperature can also be used to control the shrinkage of the sheet portion that does not have a printed pattern on its surface, thereby controlling the height of the protrusion of the sheet portion that has a printed pattern.

。FIG. 3 shows a laminated base sheet prior to heating in another embodiment of the method of the invention. That is, after irradiating a biaxially stretched resin base sheet 1 with a printed pattern with an ultraviolet curable resin ink 2 from its surface with ultraviolet rays in the same manner as described above, another resin sheet, such as vinyl chloride resin, is applied to the back surface of the biaxially stretched resin base sheet 1, which has a printed pattern printed with the ultraviolet curable resin ink 2. By adhering and laminating the sheets 3 by a method such as lamination, and then heating the sheets without stretching, as shown in FIG.
When it contracts in the printed pattern, it contracts at the same time, thus forming an uneven pattern in perfect synchronization with the printed pattern. When a colored sheet is used as the resin sheet 3, this sheet can be used as a background of a printed pattern.
