Stamp pillow for multicolor printing and method of its manufacture
(57) Abstract:The invention relates to office equipment, and more specifically to utilities in the manufacture of printed works, and can be used to paint on the stamp marking of various objects. Stamp pillow for multicolor printing contains combined with each other in General is not permeable to dye the substrate blocks double-layer media of paint, in which the upper layer of low-porosity and highly porous bottom, the ends of each block of the media paints melted the entire height of the high porosity of the lower layer, and the individual blocks of the media paints are separated from each other by a double groove, is cut through the entire thickness of the medium of paint to the substrate, and a highly porous bottom layer of the medium of paint made of woven or non-woven thermoplastic material. A method of manufacturing a stamp pads for multicolor printing is that combine dual layer media paints with not permeable to dye the substrate and then form individual units by cutting the laser beam double grooves on the entire thickness of the double layer media the ink to a substrate by the given block outlines and then filled blocks of colors. Stamenic, or rather to the auxiliary materials used in marking, and can be used to paint, for example, marking stamps.Famous stamp pad multicolor almost containing a body placed in it blocks the media paints of a porous material, and the blocks of the media paints are interconnected, for example, glue and block boundaries are dividing groove (SU 3009440 A, class B 41 K 1/54, 02.07.96).The disadvantage of this device is a high probability of mixing paints along the block boundaries when printing, which will lead to the distortion of the impression.Closest to the claimed technical solution in its essence and the achieved technical result is a stamp cushion containing cuvette placed in her blocks double-layer media paints in which the upper low-porosity layer and the bottom layer is highly porous, and the blocks are filled with different colors (US 5531829 A, class B 05 C 1/00, 02.07.96).The disadvantage of this technical solution, selected as a prototype, is the need for accurate setting of the stamps in certain areas of the stamp cushion that creates inconvenience in operation. Bromobenzene uniform dosed transfer of ink on the surface of the stamp and improving the quality of printed sheets.Conducted by the applicant's analysis of the prior art, including searching by the patent and scientific and technical information sources and identify sources that contain information about the equivalents of the claimed invention, has allowed to establish that the applicant is not detected similar, characterized by signs, identical to all the essential features of the claimed invention, and the definition from the list of identified unique prototype, as the most similar set of features analogue, has identified a set of essential towards perceived by the applicant to the technical result of the distinctive features of the claimed object set forth in the claims.Therefore, the claimed invention meets the requirement of "novelty" by applicable law.To check the compliance of the claimed invention to the requirement of inventive step, the applicant conducted an additional search of the known technical solutions in order to identify characteristics that match the distinctive features of the prototype of the claimed invention, the results of which show that the claimed invention is not obvious from the prior art, certain savici on the achievement of the technical result.The essence of the proposed technical solution is that proposed stamp pillow for multicolor printing contains a blend between a separate double-layer media of paint, in which the upper layer of low-porosity, and lower highly porous, with separate blocks of the media paints also include the total impervious to paint a substrate, the ends of each block double-layer media paint melted the entire height of the high porosity of the lower layer, and the individual blocks of the media paints are separated from each other by a double groove, is cut through the entire thickness of the medium of paint to the substrate, and a highly porous bottom layer of the medium of paint made of woven or non-woven thermoplastic material.A method of manufacturing a stamp pads for multicolor printing by forming separate blocks double-layer media paint and filling them with paint, characterized in that before the formation of the combine media paints a highly porous lower layer impervious to paint a substrate and then form individual units by cutting the laser beam double grooves on the entire thickness of the double layer media the ink to a substrate by the given block outlines euny composite material, in which the upper layer is a low-porosity, usually 20-45% with a pore size of from 10 to 80 μm, and the lower layer of highly porous, usually 40-85% or more with a pore size of about one order of magnitude higher than that of the upper layer.It should be noted that these parameters and their ratio layers of media of paint can go for the described framework, because these ratios and the parameters are not necessary for the media of paint, and show the difference in the functional purpose of each layer of the medium of paint; a highly porous bottom layer is a container for paints, low-porosity top layer is semi-permeable barrier which restricts the free flow of paint from the lower high-porous layer.The upper layer of the medium of paint can be made of woven or nonwoven material, a thermoplastic or thermosetting. For example, the material of the upper layer can be silk, cotton, polyester or similar fabric, non-woven material based on polypropylene fibers, thin felt, etc.The bottom layer of the medium of paint is made from thermoplastic woven or non-woven material based on, for example, polyurethane, polyethylene, polyester (polyethylenterephthalat of ethylene with propylene, foamed polyurethane, polybutadiene, natural rubber, etc., it is obvious that the pores in the above-mentioned layers of the medium of paint may not be the same size even in the same layer, and the pore size can vary considerably. It is also obvious that the thickness of the upper low-porosity layer of carrier material is much less than that of the lower layer, which is explained by the difference of the functions of each layer.As the substrate material used mainly polymer film from thermoplastic polymers, such as polyethylene, polypropylene, polyester, and others , are capable of reliably and without complicating the process be combined with the lower layer of the medium of paint.However, possible embodiments of the claimed ink pads, in which as the material of a step is used, for example, cardboard, impregnated with substances that prevent the penetration of paint, and many other materials.Dual layer media paints get a connection, or a combination of canvases low-porosity and high porosity of the material by gluing, welding or any other known techniques.Made of the inventive stamp pillow as the th, connect the latter to the substrate by bonding, welding or other known technique, and then thus obtained the workpiece to form individual units by cutting the laser beam double grooves on the entire thickness of the double layer media the ink to a substrate by the given contours, followed by filling the thus formed individual blocks of the media paints inks of different colors. At the same time as the laser light source use a known, commercially available lasers, such as TROTEC-25ER.In turn, highly porous bottom layer of the medium of paint (and in the case of the upper low-porosity layer from a thermoplastic material and an upper layer) is fused to the full height on the section line laser beam, thus forming a "cell" - the substrate and melted the ends of the medium of paint, impervious to paint.It should be noted that when cutting a double grooves between the individual blocks of the medium of paint is formed or, more precisely, is formed a narrow barrier of the double-layer media of paint, which also melted the side surface and the specified barrier does not allow the colors to mix when marking.Salaamaalekum device claimed stamp pillows.In Fig. 3 shows the partitioning scheme in the manufacture Tritone stamp pillows.The inventive cushion (Fig. 1 and 2) contains two layered media paints 1 in which the upper low-porosity layer 2 and bottom layer 3 of high porosity, coupled with the substrate 4. The ends 6 highly porous lower layer fused to the entire height of the substrate 4, and the blocks of the media paints B, C and D are separated from each other by a double groove 7 and the barrier 8.Works declare stamp cushion as follows.When pressing the stamp on the pillow from the side of the low-porosity of the upper layer 2 paint (not shown) contained in the blocks of the carrier 1 comes from a highly porous layer 3 in the low-porosity layer 2 and plod through it on its outer surface. This surface is ink and accordingly the reddish paint goes on the stamp and marked on the surface.An example of manufacturing the inventive stamp pillows.The materials used and the process parameters.Dual layer media paints:
The material of the top layer is Suede, J. Y. Company (Korea), thickness 1.0 mm,
the porosity of 35-40%.The material of the lower layer is Foam. Polyimide, Davies Co. (Who/BR> The thickness of 1,2 mmGlue "Moment 1", THE 2385-011-04831040-95.Used laser - TROTEC-25ER, the speed of cutting grooves 1.8 cm/sStamp pillow is made as follows.On the substrate 4 put a layer of glue 5 and impose on it a highly porous layer 3 dual-layer media paints 1. Then thus obtained (Fig. 3) the workpiece 9 mark double circuit 10 for plots B, C and D and cut by a laser beam double groove throughout the entire thickness of the medium of paint to the substrate. This partitioning and the formation of separate blocks of the media paints a laser beam is as follows.Create the program lay out a cut sheet media ink and then enter the program in the memory of a laser engraver. Placed in the working area of the engraver sheet media ink, run engraver and double cut grooves, thus forming separate blocks of the medium of paint, and the stamp pillow form cutting laser beam on the outer contour. In the finished pillow is filled with paint every single unit of media.As can be seen from the descriptions of the schemes, explanatory drawings and specific examples of the manufacture of the inventive stamp cushion the productivity and quality in comparison with the known. 1.
