A method of adapting a Lab setpoint color value of multicolored printed products, wherein a special color is replaced by process colors using an ICC color profile. A measurement point that is assigned to the replaced special color on the printed product is metrologically acquired using a color measuring system and a Lab actual color value of the measurement point is calculated. The ICC color profile or a standardized ICC color profile is used for computing the color composition of the Lab setpoint color value from the participating process colors. Changes of the layer thicknesses of the participating process colors are ascertained to achieve a predetermined Lab setpoint color value of the measurement point using a digital tool or a digital model. The participating process colors are adapted using the ascertained changes of their layer thicknesses.

Provided are a blade device equipped with a blade member which can accurately adjust pressing force due to a blade member, and a printing machine and a coating device equipped with the blade device.

A blade device 40 according to the present invention has: a blade member 41 contacting with a plate roll 10 to which coating material is to be applied; an upper holder 43 contacting with the blade member from one surface side of the blade member; a lower holder 44 contacting with the blade member from another surface side of the blade member; a tube 42 contacting with the blade member and configured to expand and contract by pressure of fluid; and a tube positioning part 43a which is provided on the upper holder and positions the tube closer to the roller, in a direction in which the blade member extends, than a tip end of the lower holder is The tube adjusts a pressing force, of the tip end of the blade member, against the roller by being expanded or contracted while being held by the tube positioning part and the blade member.

An ink fountain of an ink fountain device is provided with a fixed frame; a plate slidable on the upper surface of the plate; and an advancement and retraction mechanism advancing and retracting the plate with respect to the frame. The advancement and retraction mechanism comprises: a motor; a cam fixed to the output shaft of the motor which is integrally rotatable by rotation of the output shaft and has a cam surface shifted from an exact circle; and a rod in contact with the cam surface and advancing and retracting by the cam. The plate advances and retracts with respect to the frame by the advancement and retraction of the rod.

An apparatus and methods of decorating a metallic container are provided. More specifically, the present invention relates to apparatus and methods used to provide a decoration on a predetermined portion of a metallic container body. The decorator includes a sensor that senses decorations on metallic containers. A control system receives information related to the sensed decorations from the sensor and then determines if the decorations at least meet predetermined color, density, thickness, orientation, and consistency targets. The control system can automatically adjust elements of the decorator to correct a deficient decoration. In one embodiment, the control system can automatically adjust ink blades associated with a plurality of inking assemblies of the decorator to adjust the color, density, orientation, positioning, and consistency of decorations transferred to the metallic containers. In another embodiment, the control system can adjust a position of an inking assembly, an ink roller, a plate cylinder, a printing plate, a blanket cylinder, and a transfer blanket of the decorator.

The present invention discloses a digital ink duct for a printing press, comprising an ink tank for storing ink, a main ink pipe that communicates with the ink tank, at least one metering-type ink delivery device, ink delivery pipes, a controller and a signal acquisition device. In the present invention, high-accuracy, metering-type ink delivery devices are arranged in a queue to form a digital ink duct which replaces the traditional ink duct and supplies ink for the ink zones. The present invention can perform accurate adjustment in real time, is high in automation and digitalization degree, and can realize one-way ink delivery and avoid ink return.

Systems and methods for providing remote approval of an image for printing are provided. One system includes a processing circuit in communication with an image capturing device that is configured to capture an image of a printed product. The processing circuit is configured to process the captured image into a processed image accurate to within a tolerance in a color space to indicate the visual appearance of one or more colors. The color space is a standardized color space, such as sRGB or CIELAB. The processing circuit is further configured to transmit the processed image to a display located remote from the image capturing device and to receive an input signal from a remote input device to allow a user to approve or reject the displayed processed image for printing on a print device.

Correction values (1-n) according to image area ratios in ranges of a printing plate of a preceding print job corresponding to ink fountain keys (4-1-4-n) are obtained. Opening amounts (1b-nb) of the ink fountain keys (4-1-4-n) corresponding to the image of the printing plate (7) of a next print job are corrected by correction values (1-n) to obtain corrected opening amounts (1b-nb). In a state in which ink in an ink roller group (6) has been decreased by scraping and removing it by an ink scraper blade (15) and in a state in which the opening amounts of the ink fountain keys (4-1-4-n ) have been set to the corrected opening amounts (1b-nb), an ink film thickness distribution corresponding to the image of the printing plate of the next print job is formed on the ink roller group (6).
