<P>PROBLEM TO BE SOLVED: To provide a lithographic printing method of high workability and productivity where the water feeding rollers are much less contaminated by the ingredients removed out of the on-press development and, thus, the method has much less waste papers due to the printing failure. <P>SOLUTION: The lithographic printing method comprises (i) exposure process of lithographic printing original film, (ii) process which eliminates non-exposed area of picture recording layer out of this exposed original film by feeding damping water with dampening roller of the printing machine and (iii) printing process. The method employs a printing machine having a water feeding device which directly feed water, and keeps a swing roller as at least one roller which contacts the dampening roller 21. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
