A doctor device for the inking system of a rotary printing press has a doctor blade carrier (11) designed as a profiled strip with a groove-shaped recess. Two parallel, approvimately roof-shaped doctor blades (30, 31) adjustable against an inking roller (2) are secured on the doctor blade carrier. The doctor blades delimit an ink-receiving chamber (20) together with the inking roller (2), the groove-shaped recess of the doctor blade carrier and sealing means (33, 34) arranged at the ends of the doctor blade carrier. In order to satisfactorily seal the ink-receiving chamber against ink leakage, the groove-shaped recess has a central part that forms a main chamber and lateral parts (40, 41) arranged at the ends of the groove-shaped recess that form lateral chambers (38, 39). The lateral chambers communicate with the main chamber through throttle slits (42, 43). The ink feeding duct (21) opens into the main chamber. The lateral parts are provided with ink discharge ducts (22, 23) and venting ...

Forme inking unit for flexographic and intaglio printing machines having a variable-speed distributing cylinder

To adjust the viscosity of printing inks, a distributing cylinder with a narrow gap relative to the ink chamber is driven at variable speed whilst utilising the thixotropic behaviour in a cylindrical ink chamber. The displacement body used as the distributing cylinder allows the volume of the ink chamber to be reduced to a value which is lower by a power of 10 than in known forme inking systems. The distributed ink passes into a closed ink application space and, by an adjustable pressure, onto the screen roller. Cleaning takes place by immersing the ink feed device in a solvent, the throughflow of the solvent device being maintained until the screen roller has been cleaned completely.

Improvements in or relating to Printing Machines.

... 17,661. Crete, G. July 25, 1913, [Convention date]. Printing-surfaces; inking-apparatus.-In a printing-machine in which the ink is squirted on to the printing-surface, an additional reservoir and pipe connexions are provided by which the squirting-device may be used for squirting a cleansing-liquid on to the printing-surface. As shown, reservoirs A, B containing ink and zylol or other cleansing-liquid respectively are connected by pipes a, b and a valve R to a pump P which is connected by a pipe e to the squirting-tube D. The surplus liquid falls into a trough E connected by a pipe f, valve R<1>, and pipes g, h with the reservoirs A, B. By adjusting the valves R, R<1>, either ink or cleansing- liquid may be squirted on to the printing- cylinder from the tube D and the surplus returned to the respective reservoir.

Improvements in Inking Devices for Printing Presses.

... 10,300. Delaney, W. P., and Dickson, W. W. April 25. Inking-apparatus.-The ink supply to the duct roller 1 is regulated by a vertically adjustable saddle-plate 5 having a passage 6 communicating with a detachable plunger 9, upon which an ordinary ink can or box 10 is placed in inverted position. The reservoir 4 is readily separable from the saddle-plate 5 and plunger 9, so that when only a small quantity of ink is required, it alone need be filled. The opening 6 in the saddle-plate 5 is preferably to one side of the vertical plane through the axis of the roller 1, and the width of the strip of ink on the roller 1 depends on the vertical adjustment of the plate 5 by the nuts 17, 18. A groove 21 is formed in the saddle-plate 5 where the surface of the roller moves beneath it, so that the saddle-plate will not scrape off the ink remaining on the roll.

Flexographic printing process with wet on wet capability

The invention refers to a flexographic printing process with wet on wet capability based on controlled polymer or polymer segment precipitation that leads to gel formation of ink compounds by controlling the solubility parameter of the ink system. The mechanism to obtain a desirable wet on wet color trapping is the formation and/or presence of a gel in the applied ink film due to a controlled physicochemical mechanism of resin precipitation. This is accomplished either by controlling a change in the Hansen Solubility Parameter of the liquid in the ink through evaporation of some or all of a non-reactive and volatile solvent, or alternatively by use of a polymer comprised of two distinct and separate segments one of which is soluble in the monomer/oligomer mix and the other of which is not. The insoluble segments form a reversible gel that is broken to a liquid by shear in the application process, allowing application of a liquid ink, and is reestablished in the applied ink film in such a manner and with such strength as to allow overprinting in the wet on wet flexographic printing process.

Method of flexographic printing comprising ability of printing on wet layer

FIELD: printing. SUBSTANCE: invention relates to a method of flexographic printing, comprising the ability of printing on wet layer and based on the controlled precipitation of the polymer or polymer segments, which leads to gel formation of compounds of printing ink by controlling the solubility parameter of the printing ink system. The mechanism of obtaining the required printing ink capture while printing on the wet layer consists in formation and/or presence of the gel in the applied film of printing ink due to controlled physical-chemical mechanism of precipitation of the resin.
