Abstract: A printing machine has an ink fountain, a fountain roller in contact with the ink fountain, a ductor roller, at least an ink transfer roller and a controller configured and programmed to control the ductor roller. For the printing machine, individual graph data gr and its initial values gri, and average g of the graph data over the entire ductor roller and its initial value gi are used to change graph data gr and g during printing so as to cancel errors between measured printed densities and desired printed densities. An adjustment apparatus and method also achieve this task for such a printing machine.

Abstract: Provided is an ink supply device for a printing machine which can accurately supply a quantity of ink necessary for acquiring desired concentration while making the fine adjustment of concentration of ink by an operator unnecessary. A control device 34 of the ink supply device includes: a concentration prediction value calculation means 53 which acquires a concentration prediction value when the concentration becomes stable based on concentration measured values of a predetermined number of printed matters; a graph change value calculation means 54 which acquires a graph change value using the concentration prediction value and a concentration target value; and a control graph value calculation means 55 which acquires a control graph value for controlling a rotational angle based on a preset set graph value and the graph change value.

Abstract: The present invention provides a printer which can facilitate temperature control of a machine-plate cylinder section, can allow simple setup, and can facilitate maintenance of printing quality in continuous printing. In the printer, a machine plate is mounted on the outer circumference of a machine-plate cylinder section 12 fixedly provided on a machine-plate drive shaft 1. A fluid whose temperature is regulated is circulated in the machine-plate cylinder section 12.

Abstract: A battery pack includes a vessel 2, a battery mounted in the vessel 2 and a circuit board 3 connected to the battery. An opening 6 is formed on the surface of the vessel 2. A thin-film terminal portion 12 is formed on the circuit board 3 so that it is exposed externally through the opening 6. In this configuration, the battery pack can realize reduction in the weight and thickness and also reduce the production cost.
