Provided is a printing method which enables formation of a high-definition printing pattern with high productivity. The printing method includes a treatment liquid application step of applying a treatment liquid, in a treatment liquid set pattern, to a pattern formation region of a printing plate in the printing plate on which a pattern has been formed; an ink application step of applying an ink, in an ink set pattern, to the pattern formation region of the printing plate to which the treatment liquid has been applied; and a transfer step of transferring the ink applied to the pattern formation region of the printing plate to a substrate. The treatment liquid is used for increasing a second diameter of the ink after application of the treatment liquid compared to a first diameter of the ink landed on the pattern formation region without application of the treatment liquid.

A printing press includes a plurality of inkers. Each inker prints a different color ink. The press includes a first module, a second module, a roller and a support member. The first module has motors to drive output shafts. The second module has ink displacement units, an ink inlet to provide ink to the ink displacement units, ink channels to transfer ink from the ink displacement units to ink outlets of the second module and input shafts to removably couple to the output shafts of the first module. The roller receives ink from the ink displacement units and transfers the ink toward a substrate. The support member supports the first and second modules in at least one position relative to the roller. The support member facilitates removal of the second module.

In a printing apparatus according to an embodiment of the present invention, it is possible to inspect an image of a printed product where an image is printed accurately without scratching a print medium as the printed product. In the printing apparatus, first, a reading unit reads the image on the print medium conveyed by a conveyance unit, and a fixing unit fixes the print medium to a reading area by the reading unit. Then, control is performed so as to stop conveyance by the conveyance unit and fix the print medium by the fixing unit at the time of image reading, and release fixing of the print medium by the fixing unit and resume conveyance by the conveyance unit if the image reading is complete.

A printing press for printing on metal cans includes a plurality of inkers. Each inker prints a different color ink on the cans, and includes a first module, a second module, a roller and a support member. The first module has motors to drive output shafts. The second module has ink displacement units, an ink inlet to provide ink to the ink displacement units, ink channels to transfer ink from the ink displacement units to ink outlets of the second module and input shafts to removably couple to the output shafts of the first module. The roller receives ink from the ink displacement units and transfers the ink toward the cans. The support member supports the first and second modules in at least one position relative to the roller. The support member facilitates removal of the second module by a press operator for cleaning the ink channels.
