Title:
オフセット印刷いわゆる平版印刷方式用使用水の表面張力を低減し、湿し水とする装置
Document Type and Number:
Japanese Patent JP4246256
Kind Code:
B2
Abstract:
[Problems] Problem 1 is to reduce surface tension of water used with no use at all of IPA, etch solutions or alternative chemical additives and to decompose organic matters and living organisms such as microorganisms contained in the waster to salve environmental pollution problems and make industrial waste disposal unnecessary. Problem 2 is to provide devices for reducing surface tension of water used for offset printing, or so-called planographic printing, to make dampening water, that enable extended use of each component of a water circulation system and easily accomplish quality printing. [Means for Solving] A water treatment system for supplying dampening water for wet offset printing comprises a flow path through which water can pass; a magnetic treatment device for magnetically treating the water passing through the flow path; and a photocatalytic device for photocatalytically treating the water passing through the flow path.
