<p><P>PROBLEM TO BE SOLVED: To provide a printing method of a printing area part, in which a printing area part can be formed by fine lines having a uniform line width by a method wherein the disconnection of the printing area part due to the flowing out of ink from a printed n-gon is prevented from developing. <P>SOLUTION: In a printing method of the fine printing area parts 3', 3', etc. on a support 1 under the conditions that the intervals between the lines consisting of the printing area parts 3', 3', etc. is set to be 50-500μm, the area of the printing area parts 3', 3', etc. is set to be not more than 50% to that of the whole surface of the support 1 and the line width is set to be 5-100μm, the printing area parts 3', 3', etc. are not printed but the remaining n-gonal portion (in which n is an even number and at least 4) 2, 2, etc. are printed in a solvent soluble ink A having the viscosity of 200-1,500 mPa s. Then, after a solvent insoluble ink B is applied to the whole surface of the support 1, the support 1 is cleansed by the solvent, resulting in removing the solvent soluble ink A and the solvent insoluble ink B applied on the solvent soluble ink A. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
