Background
In the art, compression molding is widely used to apply designs, text, and other images to articles. As discussed further below, a typical stamper includes a substrate and a raised stamping surface of substantially uniform height. The stamp may be fixed to a handle or some other stamping tool such as a stamping press. In operation, a user applies ink to the stamping surface. This is typically done by pressing the stamp into an ink source such as an ink pad (ink pad), although it is also possible to apply the ink directly to the stamping surface using only a cloth, or a brush, or a sponge or other applicator. Once the ink is applied to the stamping surface, the stamp is stamped onto the article to be stamped. Typical articles that may be embossed include, but are not limited to, paper, cardboard, wood, glass, and metal.
In the case of proper use, only the stamping surface will come into contact with the article when the stamp is pressed. Such an imprint system is entirely sufficient when an imprint image with a uniform shadow is desired.
Disclosure of Invention
The present invention, in its various embodiments, is an improved stamper. The stamper includes a substrate and a stamping surface. The stamping surface also includes one or more singularities (singularities) having a substantially uniform height, one or more connected singularities, and one or more fused singularity segments. The singularity point may be a protrusion separated by one or more gaps. The cross-sectional shape of the singularity may be substantially polygonal, or the cross-sectional shape may be substantially circular. The singularity point may have a substantially flat or substantially rounded top surface. The gap may be substantially polygonal or substantially circular. The connecting singular points may include one or more connections therebetween, wherein the connections have a height substantially the same as a height of the stamping surface, and the connections may be portions of the stamping surface. The connection may be substantially horizontal, substantially vertical or substantially diagonal.
A method of making a stamper is also disclosed. In the method, a graphic impression image is generated. The graphic impression image has: a point per inch (DPI) setting of about 300-; about 600 versus 1500 bitmap settings; a line per square inch (LSI) setting of about 45-85; and about 7-80% of the lightest area of black. Engraving a three-dimensional analog of the graphic impression image into a quantity of magnesium. Forming one or more substrate sheets from the three-dimensional likeness of the graphic impression image engraved in the magnesium. An amount of precursor material is deposited into the substrate sheet and heated. As the precursor materials melt, they take on the complementary shape of the substrate plate. Once cooled, they were removed from the substrate sheet, forming a stamper. In one embodiment, the graphic impression image has: dots Per Inch (DPI) of about 600; a bitmap setting of about 1200; a line per square inch (LSI) setting of about 65-80; and about 15% of the lightest area of black. The precursor material may be a red rubber. The magnesium may be in the form of magnesium board.

Detailed Description
Referring to fig. 1-2 b, a conventional stamper 100 is depicted. Stamper 100 includes a substrate portion 102 having a raised stamping surface 104 of substantially uniform height. The stamping surface 104 includes various spaces 106 interspersed between the stamping surface 104 that, in use, are not typically in contact with the article to be stamped.
In operation, a user applies ink to the stamping surface 104. This may be accomplished by pressing stamp 100 into an ink source, such as an ink pad, or the ink may be applied directly to stamping surface 104 with only a cloth, or brush, or sponge or other applicator, as will be apparent to those skilled in the art. Once the ink is applied to stamping surface 104, stamp 100 is then pressed against the article to be stamped. Typical articles that may be imprinted include, but are not limited to, paper, cardboard, wood, glass, and metal. A block or other similar handle device 108 may be used to press the die 100 onto the article.
In the case of proper use, only the stamping surface 104 will be in contact with the article when the stamp 100 is depressed. When using stamp 100, the spaces 106 in stamping surface 104 may have residual ink therein, but typically will not be in contact with the article.
As mentioned above, such an imprint system is entirely sufficient when an imprint image with a uniform shadow as depicted at 110 in fig. 2b is desired. However, the present invention, in its various embodiments, allows a single stamper to generate images with various shadow elements and thus a higher level of realism.
Referring to fig. 3-5 b, a
Surrounding the singular point 208 is a gap 206. The gap 206 is concave relative to the singular point 208. Thus, ink typically does not adhere to the gap 206 when applied to the ink supply. Even if ink sticks to the gap 206 (e.g., due to a user pressing too deep into the ink supply), the ink will not typically contact the article being stamped, if properly used. Thus, when the stamp is raised, the gap 206 corresponds to an ink-free zone on the article being stamped. The gap 206 may vary in size, shape, and depth. In some embodiments, they may be substantially square or polygonal. In other embodiments, they may be substantially circular in shape. In some embodiments, the shape of the gap 206 may also vary within a
The connected singular points 212 can be seen in fig. 5. The connected singular points 212 may contain the same features as the singular points 208 previously discussed. However, they are characterized by a connection 209 between two or more adjacent singular points 208 (fig. 5 b). The connection 209 may be in various directions. In fig. 5 and 5b, the connection 209 is shown as a substantially horizontal and vertical connection. However, in some cases, the connectivity may extend diagonally. The connection 209 between the connected singular points 212 also has substantially the same height as the singular point 208 itself. Thus, connected singularities 212 may generate a linearly imprinted image, as opposed to discrete points generated by unconnected singularities 208.
The larger segments of the fused singular points 210 act as a substantially uniform stamping surface and, due to the larger stamping surface area, they allow a larger amount of ink corresponding to the darker shaded area to be applied to the article. As can be seen in fig. 9-11, the singular point 208 allows for the application of discrete amounts of ink to the article due to the relatively small stamping surface area of the singular point 208. By spacing the singularities 208 apart by a larger segment of the gap 206, the impression effect is a lightly shaded area. The connected singular points 212 correspond to moderately darker shades in the imprinted image due to the increased imprinted surface area provided by the combined singular points 208 and connections 209.
Fig. 6-8 depict certain embodiments of the present invention in which ink is applied to the stamping surface 204. Fig. 6 is a view of the completed stamp, while fig. 7 depicts an enlarged view of the stamping surface with ink applied. Fig. 8 depicts a further enlarged view of the stamping surface 204 with ink applied. It can be seen that the ink distribution corresponds to the segments of the singular points 208, the connected singular points 212, and the fused singular points 210, where the ink concentration is highest at the fused singular points 210, moderate at the connected singular points 212, and lowest at the segment with the single singular point 208.
Regarding manufacturing, in a typical red rubber stamper, a graphic art is created, which is used as a template for a magnesium board, which then serves as a mold for a substrate board (matrix board), which in turn serves as a mold for red rubber. The use of such templates in chemical etching techniques is well known and therefore not discussed in detail herein. However, it has been found that specific adjustments to the pixelation settings in the graphic art allow for better magnesium etching, which translates into a working stamp with feasible singularities 208 that can transfer ink from an ink source to the article being imprinted. Referring to fig. 12, in one embodiment, the pixelation setting is approximately 600 Dots Per Inch (DPI) with the shallowest region set to approximately 15% black (plus or minus 3%). The bitmap is set at 1200 and the number of lines per square inch (LSI) is set at about 65-80. These settings result in a pixel size of at least about 7 px.
However, in other embodiments, the pixelation setting may be anywhere within the range of approximately 300-1500 points per inch (DPI); the bitmap settings may be anywhere within the range of approximately 600-1500; and the LSI setting may be anywhere in the range of about 45-85% with about 7-80% being black. Thus, by adjusting the artwork resolution setting, an optimal balance of sharpness and manufacturing feasibility can be achieved.
The graphic artwork output is typically in PDF or TIFF format, but other suitable outputs will be apparent to those skilled in the art. The desired output may be generated using a variety of software systems including, but not limited to, Adobe photoshop and Adobe Illustrator, available from Adobe systems of San Jose, California.
Artwork may then be captured onto the magnesium plate using a number of known etching techniques. Chemical etching has been specifically mentioned, but other etching techniques apparent to those skilled in the art may also be used, including but not limited to photolithography and laser engraving.
Once the magnesium board is produced, it can be used by known techniques to form a substrate board that acts as a mold for the rubber stamp.
Variants
The method discussed above involves the use of chemical etching techniques in the production of the magnesium plate. However, the present invention is not intended to be limited to this particular process. Rather, the present invention contemplates any other plate engraving method, as would be apparent to one skilled in the art, into which the pixilated arrangement discussed above may be incorporated and by which the feasible singularities 208 may ultimately be molded. In certain embodiments, it may be desirable to use other metals than magnesium for making the plate.
Further, while the figures depict the invention as a red rubber stamp, it should be noted that other known imprinting materials may be utilized, including, but not limited to, photopolymers. Similar graphic artwork output can be utilized in connection with the manufacture of photopolymer stampers. However, in photopolymer production, rather than a magnesium plate, a mask and negative (negative) are produced, which can then be printed on acetate or other backing material by known techniques.
Numerous other modifications and alternative arrangements may be devised by those skilled in the art without departing from the spirit and scope of the present invention.
