A method and apparatus for dispensing ink to an ink fountain (10) of a printing press. A flexible bag (16) of ink is utilized and is compressed for forcing the ink into the fountain (10), and a sensor (94) determines the level of ink in the fountain and thus controls the force on the bag, that is, the compression on the bag. The flexible bag (16) of ink is subjected to a compressor, which can be a flexible air-filled bladder (22) which applies a force against the ink bag (16) to compress the bag, and to force ink therefrom and into the ink fountain (10).
L'invention concerne un procédé et un appareil d'apport d'encre à un encrier (10) d'une presse à imprimer. On utilise une poche (16) flexible d'encre qui est comprimée pour forcer l'encre à pénétrer dans l'encrier (10), et un capteur (94) permet de déterminer le niveau d'encre dans l'encrier et de régler la force appliquée sur la poche, à savoir la compression de la poche. La poche (16) flexible d'encre est soumise à un compresseur, qui peut être un sac (22) flexible rempli d'air appliquant une force contre la poche (16) d'encre pour la comprimer, et forcer l'encre à sortir de celle-ci pour pénétrer dans l'encrier (10).
