Abstract
A printing method comprising: imagewise exposing a lithographic printing plate precursor comprising a support and an image recording layer being removable with a fountain solution or a combination of a printing ink and a fountain solution and loading the exposed lithographic printing plate precursor on a plate cylinder of a printing press, or loading the lithographic printing plate precursor on a plate cylinder of a printing press and imagewise exposing the loaded lithographic printing plate precursor, supplying at least a fountain solution comprising a compound represented by the formula (I) defined herein to the exposed lithographic printing plate precursor so as to remove an unexposed area of the image recording layer; and performing printing.

A printing method comprising:
- imagewise exposing a lithographic printing plate precursor comprising a support and an image recording layer being removable with a fountain solution or a combination of a printing ink and a fountain solution and loading the exposed lithographic printing plate precursor on a plate cylinder of a printing press, or loading a lithographic printing plate precursor comprising a support and an image recording layer being removable with at least one of a printing ink and a fountain solution on a plate cylinder of a printing press and imagewise exposing the loaded lithographic printing plate precursor;
- supplying at least a fountain solution comprising a compound represented by the following formula (I) to the exposed lithographic printing plate precursor so as to remove an unexposed area of the image recording layer:
- wherein A and B each independently represents —CH2CH2O— or —CH2CH(CH3)O—, and A and B are groups different from each other;
- a, b, c, d, e, f, g, h, i and j each represents an integer of 1 or more, and a, b, c, d, e, f, g, h, i and j are values given such that the compound represented by the formula (I) has a weight average molecular weight of from 500 to 1,500;
- and n represents an integer of 1 or more;
- and
- performing printing.
