PURPOSE:To compose an equipment which produces a suitable ink for ink jet printing and/or writing appliances by a method wherein the lot control of the ink is practicable by understanding the dye concentration of prepared ink. CONSTITUTION:The dye concentration of ink prepared in a mixing tank 1 is detected respectively by a detector of dye concentration 11. According to this output, the last stage of lot control is carried out. The detected result obtained by a detector 11 of dye concentration is indicated on an indicator of dye concentration 15-1 placed at an indicating part of an operating unit 15. Thus, an operator will be able to perform a lot control of the produced ink, on the basis of above mentioned indication of result. |
