Title (EN) METHOD OF PAD PRINTING BY PREPARING A SELF-ASSEMBLED LAYER
(FR) PROCEDE DE TAMPONNAGE PAR PREPARATION D'UNE COUCHE AUTO-ASSEMBLEE
Abstract:
(EN) A method of pad printing comprising: a) preparing (52) a self-assembled layer of molecules covering a contact face of the pad, a self-assembled layer being a layer in which the main chains of the self-assembled molecules are parallel to each other and form an angle α that is strictly less than 90° with the direction normal to the contact face, less polar groups of the self-assembled molecules being adsorbed on the contact face and more polar groups being turned outward from the pad such that the wettability of the contact face covered with the self-assembled layer corresponds to an angle of contact with distilled water of which the value is less than 70°, b) then, following step a), moving (62) the pad to bring the self-assembled layer into contact with the face to be printed, and c) next, removing (66) the pad to leave the self-assembled layer on the face to be printed.
(FR) Procédé d'impression par tamponnage comportant : a) la préparation (52) d'une couche auto-assemblée de molécules recouvrant une face de contact du tampon, une couche auto-assemblée étant une couche dans laquelle les chaînes principales des molécules auto-assemblées sont parallèles les unes aux autres et forment un angle α strictement inférieur à 90° avec la direction normale à la face de contact, des groupements moins polaires des molécules auto-assemblées étant adsorbés sur la face de contact et des groupements plus polaires étant tournés vers l'extérieur du tampon de sorte que la mouillabilité de la face de contact recouverte de la couche auto-assemblée correspond à un angle de contact avec de l'eau distillée dont la valeur est inférieure à 70°, b) puis, à l'issue de l'étape a), le déplacement (62) du tampon pour mettre en contact la couche auto-assemblée avec la face à imprimer, et c) ensuite, le retrait (66) du tampon pour laisser la couche auto-assemblée sur la face à imprimer.
