An ink replenishment system for a can decorator having a plurality of ink fountains corresponding to a plurality of ink station assemblies includes a robotic arm structured to pick up ink from a selected one of a plurality of ink container and to place the picked up ink into a selected one of the plurality of ink fountains, and a controller structured to control operations of the robotic arm.

A printing machine includes: a printing plate attached to a plate cylinder; a blanket configured to transfer ink from the printing plate to a printed material; a blanket wheel configured to rotate the blanket; and at least one of a distance sensor or a temperature sensor. The distance sensor is provided in the blanket wheel and configured to measure a distance of the printing plate to the blanket wheel, and the temperature sensor is provided in the blanket wheel and configured to measure a temperature of the printing plate.

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.

A method for mounting one or more printing plate segments on a carrier sheet. The method comprises importing a file into a computer associated with a mounting unit. For each printing plate segment, the file includes a printing plate segment identifier, information regarding alignment of registration marks relative to the carrier sheet; and image data corresponding to a characteristic pattern associated with each printing plate segment. A composite image depicting the image data corresponding to the characteristic patterns is then displayed on a display in the predetermined arrangement of one or more printing plate segment locations and orientations. A mounting unit and a printing system and computer readable media programmed with instructions for performing the method are also described.

A sheet-fed printing machine comprises two sheet-fed printing units; of which a first is configured as a sheet-fed simultaneous printing unit and has two collector cylinders, which interact with one another and each have an axis of rotation. An axial plane contains the axes of rotation of the collector cylinders. A reference plane contains an axis of rotation of this type and has a horizontal surface normal. An intersection angle between the axial plane and the reference plane is, at a maximum, 45 degrees. A first one of the sheet-fed simultaneous printing units has exactly four plate cylinders, of which exactly two are arranged such that they directly interact with the first collector cylinder and has exactly two others which are arranged such that they directly interact with the second collector cylinder. A second sheet-fed printing unit has at least one impression cylinder and at least one plate cylinder, which is arranged such that it directly interacts with the impression cylinder and which is configured a screen printing plate cylinder, or as a flexo plate cylinder or as a numbering plate cylinder. The two collector cylinders of the first printing unit and the impression cylinder of the second printing unit have the same circumference.

A screen printing machine for appropriately contact between a mask and a board, comprising: a mask-holding device configured to hold a mask; a board-positioning device configured to hold a board and to position the held board with respect to a mask held by the mask-holding device from below; a squeegee device configured to spread a cream solder with respect to the mask; a height-measuring device configured to measure the height of the mask and the board; a control device configured to control each device, and to calculate the thickness of a mask lower layer, integrally formed with the mask, based on the measurement values obtained from the height-measuring device; and an operation display device configured to input operation and to display calculation values from the control device, and the like.
