PURPOSE: A cleansing composition for an intaglio plate for offset printing is provided to obtain reproducibility of a printing pattern without damaging to an intaglio plate with micro patterns by not containing an anticorrosion agent and fluorine compounds. CONSTITUTION: A cleansing composition for an intaglio plate for offset printing comprises 1-25 weight% of an organic amine compound, 10-70 weight% of an aromatic alcohol, and 20-80 weight% of an organic solvent. The organic amine compound is represented by chemical formula 1. In chemical formula 1, each of R1-R3 is independently hydrogen, a substituted or unsubstituted C1-10 alkyl group, a substituted or unsubstituted C2-10 alkenyl group or hydroxyalkenyl group, a carboxyl group, a substituted or unsubstituted C5-8 cycloalkyl group or hydroxycycloalkyl group, a phenyl group, or a benzyl group. |
