PRINTING SYSTEM OF ORGANIC SOLVENT-BASED PRINTING INK COMPOSITION AND ORGANIC SOLVENT-BASED PRINTING INK COMPOSITION UTILIZED IN PRINTING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a printing system that enables to obtain beautiful printed matter and permits recovery of an organic solvent to suppress discharge thereof into the air and reutilization of the recovered organic solvent by addition thereof to an ink as a diluting solvent by employing a printing ink having good printing aptitude and permitting recovery and reutilization of a solvent and a recovering means of a solvent.;SOLUTION: The printing system of an organic solvent-based printing ink composition reutilizes a recovered organic solvent by recovering the organic solvent evaporating with printing with the organic solvent-based printing ink composition and adding and mixing the recovered organic solvent as a diluting solvent to the organic solvent-based printing ink composition for subsequent printing, where the solvent composition of an ester solvent and an alcohol solvent in the organic solvent-based printing ink composition is such that the mass ratio thereof is 1.00≤(ester solvent)/(alcohol solvent)8.95.;COPYRIGHT: (C)2009,JPO&INPIT
