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.

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 deviceof the ink supply device includes: a concentration prediction value calculation meanswhich 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 meanswhich acquires a graph change value using the concentration prediction value and a concentration target value; and a control graph value calculation meanswhich acquires a control graph value for controlling a rotational angle based on a preset set graph value and the graph change value.

Ink supply device for printing machine

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 sectionfixedly provided on a machine-plate drive shaft. A fluid whose temperature is regulated is circulated in the machine-plate cylinder section

Printer

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