Abstract
(EN)
In order to form ink filling recesses for forming colored pattern layers by a simple process, a master (12) having a plurality of protrusions (13) which are arranged into a predetermined arrangement is produced. The master (12) is tightly pressed against an ink filling layer precursor (11), the ink filling layer precursor (11) is solidified to form an ink filling layer (14), and the ink filling layer (14) is removed from the master (12), forming the ink filling layer (14) having a plurality of the ink filling recesses (15) by transfer. The ink filling recesses (15) are filled with inks with predetermined colors to form the colored pattern layers (16).

Pour former des alvéoles réceptrices d'encre, servant à constituer par un procédé simple, des couches de motifs en couleur, on crée un cliché maître (12) comportant une série de saillies (13) disposées dans un ordre déterminé. Le cliché maître (12) est fermement pressé contre un précurseur (11) de couche d'encrage qui se solidifie pour donner une couche d'encrage (14) laquelle, est éliminée du cliché maître (12) pour former par transfert une couche d'encrage (14) présentant une série d'alvéoles réceptrices (15) d'encre. Lesdites alvéoles (15) sont remplies d'encres de couleurs prédéterminées qui produiront les couches (16) du motif en couleur.
