Abstract
The invention provides an aquatic ink temperature controller in a gravure printing machine using the aquatic ink which can prevent photographic fog phenomenon owing to season. A heat exchanger (10) is installed in a temperature adjustment printing ink circulation loop (8) for maintaining the temperature of the aquatic ink in an ink tank (1) between 15-28 DEG C at which photographic fog is avoided. A control circuit (15) performs a feedback control for the driving of a heat source machine (12) according to signals from a sensor (16), so that the heat exchanger (10) makes the temperature of the aquatic ink in the oil tank (1) be 15-28 DEG C.
Description
technical field [0001] The invention relates to a water-based ink temperature regulating device in a gravure printing machine using water-based ink. Background technique [0002] In a gravure printing machine, the use of water-based ink is extremely effective in terms of environmental measures and improvement of the printing work environment compared with the use of oil-based ink. No. 11-250423, Japanese Patent Application No. 2000-141712, and Japanese Patent Application No. 2000-106154 are inventions for practical application. [0003] In addition, in the case of water-based ink, the temperature of the ink used has a significant impact on the completion of printing, so the applicant of the present invention has proposed to adjust the temperature of the ink to 15°C to 28°C for printing (Japanese Patent Application No. 2002-086886 ). [0004] That is, the temperature of the water-based ink fluctuates greatly due to temperature changes between summer and winter. For example...
