Abstract
Formulations for solvent-based flexographic or rotogravure inks, which are capable high-quality, defect-free printing at high speeds, contain flexographic ink resins solutions and solvent mixtures which are designed to maintain a dynamic solubility parameter in the ink as the dry state is approached during the printing process. The inks described show extremely high quality printing at linear press speeds above 1800 fee per minute (ca 0.549 km/min).
