    摘要: In some examples, a screen printing unit includes a screen printing forme cylinder, an impression cylinder, and at least one further rotational transport body. A fixing element of the impression cylinder includes inner and outer contact surfaces for clamping sheets. The inner contact surface has a base radius as a distance from an axis of rotation of the impression cylinder. A cylinder barrel of the impression cylinder has a supporting surface for sheets that includes an impression portion having a constant barrel radius, which extends over at least 170° about the axis of rotation of the impression cylinder and the barrel radius is larger than the base radius. A fixing element of the further rotational transport body includes an inner and an outer contact surface for clamping sheets. The inner contact surface includes the base radius as a distance from an axis of rotation of the further rotational transport body.

    摘要: A photoelectric sensor 60 and squeegees 32 and 42 are fixed to a slider, when outward movement printing in which solder on a screen S is rolled by an outward movement of the right squeegee 32 is completed, the right squeegee 32 is separated from a state of contacting a right end R1 of a solder roll and a squeegee position p1 at that time is input, and, subsequently, the slider is returned until the photoelectric sensor 60 detects a left end R2 of the solder roll and a squeegee position p2 at this time is input. An amount (a solder roll width R) of solder remaining on the screen S is calculated by subtracting a movement amount S from the squeegee position p1 to the squeegee position p2 from a distance X from the right squeegee 32 to an optical axis position of the photoelectric sensor 60 on the screen S.

    摘要: A measurement apparatus for measuring values for color adjustments in a print technique includes a measurement instrument including a measurement value detecting device at an arbitrary measurement point, a movement device, a reference coordinate calculation device, a measurement coordinate calculation device, and a computation device. The reference coordinate calculation device calculates a measurement point reference coordinate value. The measurement coordinate calculation device compares both origins to calculate a corrected value relative to the coordinate system of the reference-image, and corrects the position of the measurement origin based on the corrected value to correct the reference coordinate value and calculates a measurement coordinate value in the coordinate system of the measurement-image corresponding to the measurement point of the reference-image. The computation device calculates information for comparing and evaluating the measurement value acquired at the measurement point of the reference-image and the measurement value acquired at the measurement point of the measurement-image.

    摘要: There is described a device (1) for offline inspection and color measurement of printed sheets for the production of banknotes and like printed securities, comprising (i) a console (10) having a supporting surface (10a) for supporting a sample printed sheet (S), (ii) a multipurpose measuring apparatus (20), which multipurpose measuring apparatus (20) comprises multiple sensors (22, 23) including at least one camera (22) for taking images of selected portions of the sample printed sheet (S) and a color measurement sensor (23) for performing spectrophotometric, colorimetric, and/or densitometric measurements at selected locations on (22, 23) the sample printed sheet (S), (iii) a display (30) for displaying the images taken by the camera (22) and the measurements performed by the color measurement sensor (23), and (iv) a control and processing unit (40) coupled to the multipurpose measuring apparatus (20) and the display (30). The device (1) comprises a move-sensor beam (200) housing the multipurpose measuring apparatus (20), which moveable sensor beam (200) is displaceable along an x-axis over the supporting surface (10a) of the console (10) and over the entire surface of the sample printed sheet (S) located on the supporting surface (10a), the multiple sensors (22, 23) being mounted on a common sensor head (21) which is displaceable within the moveable sensor beam (200) along a y-axis so that the multipurpose measuring apparatus (20) can selectively take images of selected portions of the sample printed sheet (S) by means of the camera (22) or perform measurements at selected locations on the sample printed sheet (S) by means of the color measurement sensor (23). The control and processing unit (40) is configured to control displacement of the moveable sensor beam (200) along the x-axis and of the sensor head (21) along the y-axis.

    摘要: There is described an intaglio printing press comprising a plate cylinder (8) carrying one or more intaglio printing plates (8c) and an impression cylinder (7) cooperating with the plate cylinder (8), a printing nip being formed between the plate cylinder (8) and the impression cylinder (7). The plate cylinder (8) and the impression cylinder (7) each comprise one or more cylinder pits (8a, 7a) and a corresponding number of cylinder segments (8b, 7b), the plate cylinder (8) and the impression cylinder (7) being in rolling contact with one another during printing operations along their respective cylinder segments (8a, 7b) when no cylinder pits (8a, 7a) are present at the printing nip. The intaglio printing press further comprises a monitoring system (150) designed to monitor a rolling condition of the impression cylinder (7) with respect to the plate cylinder (8) and to provide an indication as to whether or not the rolling condition corresponds to a desired rolling condition, the desired rolling condition being a rolling condition corresponding to true rolling of the impression cylinder (7) with respect to the plate cylinder (8) where no slippage occurs between a circumferential surface of the impression cylinder (7) and a circumferential surface of the plate cylinder (8). Also described is a method of monitoring operation of an intaglio printing press.

    摘要: An ink supply apparatus of a printing press includes at least one inking device. In the inking device, an ink fountain roller is rotatably supported. An ink fountain main body forms a space to store an ink together with an outer surface of the ink fountain roller. A guide member slidably supports the ink fountain main body and guides the ink fountain main body between a first position where the space is formed and a second position spaced apart from the ink fountain roller than the first position. A doctor including a blade is attached to a doctor holding member between the ink fountain main body and the ink fountain roller when the ink fountain main body is located at the second position. The blade abuts against the ink fountain roller and cleans the ink fountain roller.

    摘要: The present invention relates to an image evaluating apparatus, an image evaluating method, and a non-transitory storage medium. In the present invention, two-dimensional relative positions between the image formation position of one color plate of a plurality of color plates and the image formation positions of other color plates are calculated based on known positional information of registration marks formed by the color plates and positional information of the registration marks that are actually formed as images on a recording medium. A position expressing image is generated which represents the calculated relative positions by way of two-dimensional positional coordinates.
