Method for manufacturing printing sheet for digital printing using screen yarn woven with polyester monofilament and printing sheet for digital printing manufactured by the same

A method for manufacturing a printing sheet for digital printing by using a screen yarn woven with a polyester monofilament, the method comprising:

• a process of preparing a screen yarn fabric woven for printing by using the polyester monofilament for at least 50 wt % of warp and/or weft yarns in a method of mechanically maintaining or feeding the weft yarn;
• a first knife coating process of performing surface treatment while cutting a surface of the screen yarn fabric woven with polyester monofilaments by a first comma coating machine in a gap between a first comma knife of the first comma coating machine and the screen yarn fabric coated with a coating solution;
• a second knife coating process of knife-coating the screen yarn, which is knife-coated in the first knife coating process by the first comma coating machine, by a second comma coating machine as same as the first knife coating process to secure a coating property without liquidity;
• a transfer process of transferring the screen yarn that has undergone the first and second knife coating processes to a heating chamber by a transfer device in order to dry the screen yarn;
• a first drying process of thermally drying the screen yarn that has undergone the first and second knife coating processes through the heating chamber having a temperature of 180° C. to 220° C.;
• a side cutting process of cutting both side gripping surfaces of the knife-coated screen yarn that is thermally dried while passing the heating chamber in the first drying process by a side cutter to side-cut both side surfaces into various widths of a constant size;
• and
• a winding process of forming the knife-coated screen yarn that has a predetermined width by side-cutting the both side gripping surfaces in the side cutting process into various sizes by using a winder.
