METHOD OF PRODUCING INDENTED SHEET

摘要

The present invention provides a method of producing an indented sheet on which indents on an indented roller surface are transferred onto a surface of a sheet-shaped object. The method comprises the steps of : continuously running a band-shaped flexible sheet-shaped object; coating a radiation curable resin solution on a surface of the continuously running sheet-shaped object to form a coated layer; transferring indents on the indented roller surface onto the coated layer with the continuously running sheet-shaped object being wound onto the rotating indented roller; curing the coated layer by irradiating radiation with the continuously running sheet-shaped object being wound onto the indented roller; and peeling the continuously running sheet-shaped object from the indented roller, wherein the transferring step, curing step and peeling step are carried out inside a casing, and temperature and humidity in the casing are controlled to be within a certain variation range with respect to a target value.
