PURPOSE: A printing method by sequentially jumping the knot of the raw textile is provided to prevent printing failure and loss of raw material, and to improve the quality and the productivity by detecting the knot with a knot detector and automatically controlling sequential squeegeeing. CONSTITUTION: Raw textile is supplied by a raw material supply unit, and squeegees are transferred by a screen frame and a carrier. Squeegee units(#1-#n) are driven independently in a screen printing machine, and the raw textile is dried by a raw material drying machine. A knot detector is composed of laser sensors, and installed in the front of the screen printing machine to detect the knot of the raw textile according to the difference of thickness of raw textile. A central processing unit of a control box transmits signals to sequences(S1-Sn) of the squeegee units to which the knot of the raw textile is placed with program, and stops printing by jumping the squeegee unit with the raw textile having the knot by controlling servo motors(M1-Mn).
