PURPOSE: To enable to easily produce a painted ceramic board having excellent three-dimensional feeling with high productivity, by a method wherein a thickly built-up printing image part or a raised pattern is printed in a ceramic ink by a 45W80 mesh silk screen, followed by firing at a temperature of not higher than 1,300°C.
CONSTITUTION: After drawing one or more desins, the thickly built-up printing image part or the raised pattern is formed by printing. In this case, a coarse screen of about 45W80 mesh is used, and printing in a ceramic ink or the like is conducted through the screen by moving a squeegee in a fixed direction, followed by drying. By repeating printing and drying an appropriate number of times, a thickly built-up raised pattern is formed. After sufficient drying, temperature may be raised to about 200°C in a relatively short time, after which the temperature is raised slowly to about 600°C, since combustion or decomposition or organic matter in the blank material starts about the time when the temperature exceeds 200°C. The temperature of about 600°C is maintained for 10W30min to complete decarburization, and thereafter the temperature is raised at a rate of not higher than 150°C/hr to, for example, 1,200W1,300°C.
