Title
(EN) LITHOGRAPHIC PRINTING PLATE TREATED WITH ORGANO-PHOSPHONIC ACID CHELATING COMPOUNDS AND PROCESSES RELATING THERETO
(FR) PLAQUE POUR IMPRESSION LITHOGRAPHIQUE TRAITEE PAR DES COMPOSES CHELATANTS D'ACIDES ORGANOPHOSPHONIQUES ET PROCEDE DE TRAITEMENT
Abstract
(EN)
The water-loving properties of an anodized aluminum lithographic surface are enhanced or restored by treatment with a solution containing a monomeric, organo-phosphonic acid chelating compound or salt thereof. Such treatment can take place following, during or in lieu of the treatment of anodized aluminum in web form with an alkali metal silicate in the process of manufacturing printing plates. Alternatively, the treatment can be carried out as a plate is developed and/or prepared for the press. In a third approach, an organo-phosphonic acid chelating compound can be incorporated into a fountain solution, ink or correction fluid.
(FR)
L'hydrophilie d'une surface lithographique en aluminium anodisé est améliorée ou régénérée par un traitement avec une solution contenant des composés chélatants monomères du type acides organophosphoniques ou leurs sels. Ces traitements peuvent se faire durant ou à la place du traitement de l'aluminium anodisé sous forme de bande, ou avec un silicate de métal alcalin dans le procédé de fabrication de plaques d'impression. Egalement, le traitement peut être fait lorsqu'une plaque est développée et/ou préparée pour la presse. Une troisième approche consiste à incorporer un composé chélatant organophosphonique dans la solution de mouillage, l'encre ou le liquide correcteur.
