DRYING UNIT FOR DRYING PRINTED SUBSTRATES
The invention relates to a drying unit (22) for drying printed substrates (21), comprising a chamber (23) with a gaseous medium which is oxygen-reduced by means of an inert gas, wherein the substrates (21) are guided through the chamber (23) or at least can be guided through the chamber, and the chamber (23) has an entrance for the substrates (21) to be guided into the chamber (23) in the transport direction (T) of the substrates (21). The entrance for the substrates (21) to be guided into the chamber (23) is formed by two cylinders (04; 06) which are positioned against each other longitudinally. The cylinders (04; 06) positioned against each other at the entrance of the chamber (23) form a printing unit (03). One of the cylinders (04) is designed as a printing cylinder (04), and the other cylinder (06) is designed as a cylinder (06) which interacts with the printing cylinder (04) and applies a printed image onto the affected substrates (21). The two cylinders (04; 06) which are positioned against each other under pressure at the entrance of the chamber (23) form a seal which runs axially to the cylinders (04; 06) for preventing the oxygen-reduced gaseous medium from leaking out of the chamber (23) and/or for preventing oxygen from the ambient air from entering the chamber (23). The printing unit (03) arranged at the entrance of the chamber (23) is designed as a printing unit (03) for an intaglio printing process.
GRAVURE PRINTING UNITS FOR PRINTING ONTO SUBSTRATES BY A GRAVURE PRINTING METHOD
Recess printing units are usable for printing on a substrate and using associated methods for operation. The recess printing units comprise an intaglio printing cylinder, which provides an image-forming pattern of recesses on its circumference; and an inking unit for applying ink to the pattern of recesses that are provided on the intaglio printing cylinder. The inking unit comprises a first inking unit cylinder which has, in a region of its lateral surface, recesses corresponding to the recesses in the intaglio printing cylinder and to which recesses ink can be supplied by an ink application device in the region of an application point lying on the circumference of the first inking unit cylinder. A second inking unit cylinder cooperates with the first inking unit cylinder and has, in a region of the lateral surface of the second inking unit cylinder, elevations corresponding to recesses in the intaglio printing cylinder or raised regions corresponding to regions of the image-forming pattern of recesses on the intaglio printing cylinder, which regions comprise recesses. The ink application device also comprises, on at least a downstream side of the application point, with respect to the operating direction of rotation of the inking unit cylinder comprising the recesses, a retaining device in the form of a doctor blade or an ink knife. The second inking unit cylinder comprises, on a lateral surface thereof, elevations corresponding to engraving on the intaglio printing cylinder.
AN APPARATUS AND PROCESS FOR PRINTING WITH TACTILE AND GLITTER EFFECT ON FLEXIBLE SUBSTRATE AND PRINTED SUBSTRATE THEREOF
An apparatus and process for producing multicolour print with tactile and glitter or other effect on a flexible substrate (100, 400A) is disclosed. The rotogravure printing machine includes a plurality of printing stations (402, 404, 406, 408 and 410) and an inline coating station (412). Printing cylinder of at least one of the printing stations is engraved with depth (d1, d2) between 20 microns and 300 microns, to transfer large volume of radiation curable inks mixed with or without glitter. The coating station (412) provides a clear coat of radiation curable coating mixed with or without glitter, at desirable location on the substrate. The gravure or flexography based coating station may apply spot coating or overall coating based on the requirement. At least one of the printing stations and the coating station may include curing unit (422, 424, 426 and 432) for curing the printed ink and applied coating.
Sheet-fed printing press for simultaneous recto-verso printing of sheets, in particular for the production of security documents
There is described a sheet-fed printing press (1000; 1000*) comprising at least two printing units (200; 200.1, 200.2; 200.1*, 200.2*) located one after the other, each printing unit (200; 200.1, 200.2; 200.1*, 200.2*) being adapted to carry out simultaneous recto-verso printing of the sheets (S) and including two printing cylinders (105, 106) cooperating with one an other and forming a printing nip, the two printing cylinders (105, 106) each collecting ink patterns from at least two associated plate cylinders (15A, 15B, 16A, 16B) wherein the two printing cylinders (105, 106) are located one above the other such that the sheets (S) travel laterally through each printing unit (200; 200.1, 200.2; 200.1*, 200.2*) from a first lateral side (201 a; 201 a*) located upstream of the printing nip to a second lateral side (201 b; 201 b*) located downstream of the printing nip, wherein a number of at least two sheet transfer elements (110, 120, 95) is provided downstream of the printing nip of a first one (200.1; 200.1*) and upstream of the printing nip of a second one (200.2; 200.2*) of the at least two printing units (200.1, 200.2; 200.1*, 200.2*) to transfer the sheets (S).
Use of thiazolide compounds for the prevention and treatment of viral diseases, cancer and diseases caused by intracellular infections
The invention provides for the use of pharmaceutical compositions comprising a thiazolide in the stimulation of the immune system in a subject in need thereof, thereby preventing and/or treating viral diseases, cancer and diseases caused by intracellular protozoan infections.
