PURPOSE: To perform transfer so that color shift enters a tolerance range by using material quality of which the glass transition temp. is higher than the highest heating temp. at a time of treatment as a protective cover.

CONSTITUTION: In a transfer method of a color art system wherein a temporary support 2 to which patterns 2 after exposure and development are bonded is passed through the nip between heat rollers along with a protective cover 1, as the material quality of the protective cover 1, aluminum, polyimide or polycarbonate being material quality of which the glass transition temp. is higher than the highest heating temp. at a time of treatment is used or material quality wherein a product of glass transition temp. and thickness is 20 (°C.mm) or more is used. Even if the transfer passing the temporary support 2 through the nip between heat rollers along with the protective cover 1 is repeated any number of times, transfer wherein finish accuracy is good, that is, color shift is within a tolerance range can be performed.
