Title
(EN) METHOD OF DETERMINING INK RECEPTIVITY ON SURFACES
(FR) PROCEDE DE DETERMINATION DE RECEPTIVITE A L'ENCRE
Abstract
(EN) A method for determining ink receptivity on surfaces is disclosed. The method may be used to predictably and reliably screen suitable substrate coating compositions (and/or substrates) or alternately suitable ink compositions in printing applications. The method relies on determining the response of a surface to ink(s) in terms of the force needed to immerse and remove a sample of the surface from an ink. Preferably, the force is expressed in terms of a contact angle of the ink with respect to the surface. By adjusting the composition of the substrate coating composition (and/or substrate) or of the ink to result in the inks behaving in a similar fashion to the coated or uncoated substrate, predictable printed image characteristics may be obtained relating to such propreties as image density and definition.
(FR) L'invention concerne un procédé de détermination de la réceptivité de surfaces à l'encre. Ce procédé peut s'utiliser dans le domaine de l'impression pour cribler de façon prévisible et sure des compositions convenables pour revêtement de substrats (et/ou pour substrats), ou bien des compositions d'encre appropriées. Ce procédé consiste à déterminer la réaction d'une surface à une encre ou à des encres en termes de force requise pour immerger un échantillon dans de l'encre et l'en retirer. Cette force est de préférence exprimée par l'angle tangentiel entre l'encre et la surface. En ajustant la composition pour revêtement de substrat (et/ou pour substrats) ou de l'encre par rapport aux caractéristiques d'encres au comportement analogue sur un substrat enduit ou nu, on peut aboutir à des caractéristiques prévisibles de l'image imprimée en termes de densité et de définition de l'image.
