Embodiment Construction

[0036] Before describing the embodiments of the method according to the invention with specific reference to these figures, a detailed example of an advantageous and preferred embodiment of a printing ink according to the invention in the form of an offset printing ink in combination with laser drying will first be given .

[0037] As effective substances, organic peroxides, in particular sodium peroxoborate or tert-butyl peroxy 2-ethylhexanoate, are mixed with PE wax in a proportion of 10% by weight and used as beads of about 1 μm size in the production of printing inks Added at a weight percentage of 1.5. The active substance is therefore surrounded by PE wax as delivery substance and is thus inactive. The behavior of the beads in the printing ink mixture is that of the PE wax additives commonly used on the market, eg as anti-scratch additives.

[0038] Printing inks can generally be printed on the printing material, and their behavior in the inking unit of a printing pres...

Abstract

A method for drying printing ink (12) containing an inactive active substance (14) enclosed before drying in a reaction-inhibited form in a transport substance (16), for accelerating the drying of the printing ink on a print medium (10), includes applying the printing ink (12) to a print medium (10) being dried at a reaction site by supplying energy to the printing ink (12), and releasing the active substance (14) by an energy supply (18) from the transport substance (16) at the reaction site for activation. The invention discloses a printing ink including an active substance (14) enclosed before drying in a reaction-inhibited form in a transport substance, for accelerating the drying of the printing ink on a print medium (10), wherein the active substance (14) is releasable during the drying by an energy supply from the transport substance (16) at the reaction site.

Description

technical field [0001] The invention relates to a method for drying a printing ink comprising an inactive active substance for accelerating the drying of the printing ink on a printing substrate, wherein the printing ink applied to the printing substrate dries at reaction sites, This is done by supplying energy to the printing ink and activating the active substance at the reaction sites. Furthermore, the invention relates to a printing ink which contains an active substance for accelerating the drying of the printing ink on the printing material, wherein the active substance is contained in the printing ink inactive before drying and upon drying Can be activated. Background technique [0002] Printing materials provided with printing inks, in particular offset printing inks, flexographic printing inks or screen printing inks, usually have to be treated in a targeted manner or by using correspondingly suitable devices prior to further printing, processing or treatment. Dry...
