A method for printing on a curved surface and a printed curved surface body using the method. The method includes the steps of: applying printing ink having a viscosity of 5-500 PaS, preferably 5-250 PaS, to a protrusion portion of a relief printing master plate 3 which is a flat plate with the protrusion portion 0.1-50 µm high, preferably 0.1-25 µm high in height h ; pressing a rubber or rubbery roll-like elastic blanket 2 having an elastic portion whose thickness T has a relation of 2H≤T≤8H with respect to a level difference H of a to-be-printed curved surface body 10 and which has a hardness (JIS A-scale) of 3-40, preferably 3-20, onto the relief printing master plate 3 supplied with the printing ink while applying constant pressure to the roll-like elastic blanket 2 and smoothly rotating the roll-like elastic blanket 2, so as to transfer the printing ink to an outer circumferential surface of the roll-like elastic blanket 2; and moving the roll-like elastic blanket 2 having the printing ink transferred thereto, and bringing the roll-like elastic blanket 2 into rotational pressure contact with a surface of the to-be-printed curved surface body 10 so as to perform printing thereon.

In order to print identification marks (200, 200') in the exact target position on a value or security document (100), the invention relates to a printing forme device (700) for applying identification marks (200, 200') to a printing stock (105). Said device (700) comprises at least one numbering unit (800) which is arranged on a rotatable holding element (710) and the position of which on the rotatable holding element (710) is adjustable. According to the invention, (a) at least one identification mark (200, 200') is printed onto the printing stock (105); (b) the position of the at least one identification mark (200, 200') on the printing stock (105) is ascertained; (c) the ascertained position of the at least one identification mark (200, 200') is compared with a target position; and (d) the position of the at least one numbering unit (800) on the rotatable holding element (710) is adjusted.

A printing press capable of performing irradiation with a sufficient quantity of ultraviolet securely to preventing incomplete curing of ultraviolet curable ink and an ultraviolet radiation method of the printing press are provided. The present invention is a printing press 100 including a printing section A provided with a plurality of impression cylinders 2 to which a printing section gripper 11 gripping and guiding a substrate 1 is attached, and a printer brought into adjacent contact with the impression cylinder 2 and printing ultraviolet curable ink onto the substrate 1 to make a printed object, and a paper ejecting section B provided with a chain 5 to which a paper ejecting section gripper 12 for gripping and guiding the printed object 1a is attached, wherein ultraviolet irradiators 21, 22 for irradiating the printed object 1a with ultraviolet are provided, and ultraviolet receivers 21a, 22a capable of receiving ultraviolet are attached to the grippers 11, 12 facing the ultraviolet irradiators.
摘要:
L'invention est relative à un procédé pour imprimer sur un support une image en couleur, caractérisé par le fait qu'il comprend les étapes consistant à :
décomposer l'image à reproduire en une composition de surfaces élémentaires colorées (24), lesdites surfaces élémentaires étant disposées selon une répartition prédéterminée (22), la couleur de chaque surface élémentaire étant choisie parmi un ensemble prédéterminé de couleurs de base et un ensemble prédéterminé de nuances de ces couleurs de base (23), le nombre de nuances pour au moins une couleur de base étant supérieur ou égal à trois, le choix de la couleur de base et de la nuance attribuée à chacune desdites surfaces élémentaires étant effectué de manière à ce que ladite composition de surfaces élémentaires colorées (24) reconstitue visuellement l'image à reproduire, imprimer ladite composition de surfaces élémentaires colorées sur ledit support au moyen d'encres dont les teintes sont choisies de manière à pouvoir reproduire, compte-tenu de la couleur dudit support, lesdites couleurs de base et leurs nuances lors de l'impression, la nuance d'une couleur de base attribuée à une surface élémentaire donnée étant obtenue lors de l'impression en jouant sur la proportion de chaque encre au sein de la surface élémentaire correspondante sur le support.
摘要:
A printing head for flexographic printing on thin-walled objects not exhibiting a perfectly smooth surface, the printing head comprising an inking roller, which rotates on contact with a flexographic printing plate borne on a printing plate bearing roller, in which the printing head comprises a roller bearing a transfer surface which rotates on coming into contact with the printing plate, the transfer surface being a perfectly smooth and faultless surface and being made of a material that is more yielding than a material of which the flexographic printing plate is made.
