Title (EN) INK COMPOSITION FOR ROLL PRINTING
(FR) COMPOSITION D'ENCRE POUR IMPRESSION AU ROULEAU
Abstract: front page image
(EN)An ink composition for roll printing is provided. The ink composition uses a solvent having an evaporation rate (Vt) of at least 0.09 mg/cm2-min and an absorption rate (St) into a blanket of less than 3.5 mg/cm2-min. The use of the highly volatile solvent can minimize swelling of the blanket without impairing the dispersibility of a pigment in the ink composition. Therefore, the uniformity of a pattern formed using the ink composition can be maintained and the formation of defects by the solvent can be minimized.
(FR)L'invention concerne une composition d'encre pour impression au rouleau. La composition d'encre fait appel à un solvant présentant un taux d'évaporation (Vt) d'au moins 0,09 mg/cm2-min et un taux d'absorption (St) dans un blanchet inférieur à 3,5 mg/cm2-min. L'utilisation du solvant hautement volatil peut réduire à un minimum le gonflement du blanchet sans altérer la dispersibilité d'un pigment dans la composition d'encre. Par conséquent, l'uniformité d'un motif formé à l'aide de la composition d'encre peut être conservée et la formation de défauts par le solvant peut être réduite à un minimum.
