(1) Field of the Invention
The present invention relates to a color stamp and its manufacturing method, in particular to a stamp using an overprint method to achieve color mixing and printing effects.
(2) Description of the Prior Art
In a conventional stamp, the color of a printed pattern depends on the color of an ink pressed onto the surface of the stamp. If one wants to obtain a pattern in different colors by using a stamping method, the only way is to obtain the corresponding color inks, and thus the basic tools required by a stamp craftsman to make creative stamps include inks and materials in various different colors. In addition, the ink of a normal stamp must be printed uniformly and clearly without any overlap. Even for master and slave stamps or a stamp set, no overlap is allowed in any portion of the pattern.
The so-called color stamp has a plurality of ink absorption areas with different and unmixed colors to produce different blocks of the pattern in different colors. In other words, the inks of different colors are coated directly onto the surface of the stamp to give a color effect to the stamped pattern. The inks of different colors are maintained clear and separated from each other, or the stamp with an adhesive is stamped at a desired position, and then a full-color decorative powder such as a glitter powder is sprinkled onto the adhesive to show the color effect. In summation, the colors of the foregoing stamps are different from what we know about colors traditionally. It also indicates that color stamps are in urgent needs.
In the aforementioned stamps, there is a stamp set which never has the overprint stamp mode, and the stamp set generally adopts a conventional technology to print a pattern in different colors with inks, but the printing effect is poor. The traditional way of making stamps is limited to the different kinds of inks, printing materials and patterns. However, it is very rare to find a good stamp overprint with a three-dimensional color effect among these traditional stamps.
In view of the traditional stamps without an overprint function, it is not an issue of the ink, but an issue of the structure of the stamp. A vast majority of stamp patterns are composed of lines or surfaces. In the process of pressing or coating the ink onto the stamps each time, it is difficult to have a uniform coating of ink, and thus the result will be very complicated or unexpected if the stamp is pressed or coated with a different ink next time. Obviously, the traditional stamps are unable to achieve a color-harmonic effect.
In the printing industry, screen printing is an excellent technique for stamping a pattern. After any pattern is screen printed, small invisible points which are generally called “mesh points” are centralized to provide one to several times of spaces around each color mesh point, such that the inks of different colors can occupy the spaces to produce a color mixing and illusive effect.
1. It provides convenience and good feeling of carrying a color printing tool to allow users to stamp a favorite three-dimensional color pattern to a position including clothes, bags or even bodies anytime and anywhere.
2. It overcomes the issue of insufficient colors, and an overprint of different colors achieves the color-harmonic function, and several basic colors are required to produce different colors and both dark and light colors.
3. It helps those not so skillful to produce lively color patterns.
4. It solves the problem of requiring a large machine for color printing, and only a small stamp can produce an artwork up to the color publication level.
5. It expands the area of stamp artcrafts and allows stamps to enter into our daily life. Users can apply a personal color 3D stamp on documents, clothes, packages, objects, or even any part of their body. Card or business card manufacturers no longer require a special printing machine to produce personal color uniform, bags and stationeries, etc to achieve the effects of making our life full of fun, changing the color of our body without relying on tattoos, giving us a better health and a more beautiful world.
The main characteristic of the present invention resides on that a pattern used for manufacturing a stamp by a screen printing, regardless of a color pattern or a monochrome pattern, goes through a screen process, such that each color can be produced by different basic colors and mesh points of different sizes. Since each mesh point has some spaces around the periphery remained for adding other colors, and the dark and light layers of the pattern cannot be expressed, the tiny invisible mesh points with different sizes are used for making diversified harmonic colors by a limited number of ink colors through visual mixing and eye illusion, so as to eliminate the drawback of the non-uniform ink of the stamp, and modify the pattern pressed by the mesh points through the visual illusion to achieve the uniform color effect. Since each mesh point has a blank around the periphery, extra ink has a space for its diffusion.
In the printing industry, the main purpose of using screen photography is to provide the layers for continuous dark and light colors that cannot be expressed by the pattern. The main purpose of the screen process in accordance with the present invention is to reserve spaces for the inks of different colors, and visual illusion and visual mixing are used for visually harmonize the non-uniform colors of the inks with two or more colors or the partially overlapped inks.
The secondary characteristic of the present invention is to use an electronic color separation method to decompose the colors of a pattern into electronic signals of three or four basic colors, and the colors are modified and films are outputted by laser spots after the modification takes place. This is called a color separation film which simply requires inks in three to four basic colors. The dark color comes with large mesh points and small peripheral spaces. The light color comes with small mesh points and large peripheral spaces for providing a better chance for printing other color inks.
The major difference between the present invention and printing resides on that stamp is a natural free-style tool, and it is very difficult to control the composition of inks, the humidity of card paper, the pressing time and the overprint precision. For the printed inks, techniques such as humidification can be used to provide a better viscosity of the inks. The inks for the stamp are generally quick drying, and the card paper does not need humidification process, and thus it makes the printing feasible, even though the stamp art craft may not be feasible for printing. In a print-color sequence, black color is generally printed first, and then green and red are printed, and finally yellow is printed. However, the stamp art craft is different or even opposite. Yellow, red and green are printed and finally black is printed. Thus, the color printing has been used for years, but the color stamp still has not been developed yet.
The present invention provides an overprint stamp having one or more mesh points to show a stamp combination of color separation films, wherein a space is maintained between mesh points and used as a method of visually harmonize the color-separation stamp in different colors through an overprint to manufacture different colors and layers. Regardless of a monochrome photo or a color photo, each pattern can use the electronic color separation to show its color separation film by mesh points, and go through the traditional stamp manufacturing method of using a photosensitive resin plate, a silk screen or even a planographic print to manufacture different overprint color-separation stamps, and common standard coordinates are used for manufacturing different styled color patterns.
The unique feature of the present invention is to use a pattern of mesh points as an overprint stamp and an overprint stamp for harmonizing the colors of the inks for each stamp. The present invention totally changes the traditional concept that the inks of a stamp cannot be harmonized, or the stamp cannot do overprints. The invention further uses the overprint stamp for drawings and creating artworks. In addition to providing overprint color-separation stamps on the same surface pattern for overprinting a drawing closest to the original surface pattern, the invention also provides a tool similar to a drawing pen for creating wonderful artworks after the overprints of different overprint stamps take place.
With reference to
The present invention includes important tasks such as the electronic color separation of the surface pattern and the screen photography for manufacturing color separation film surface patterns of overprint stamps in different colors, and each mesh point color separation film is manufactured into a color-separation overprint stamp in different colors by using conventional stamp manufacturing techniques. Users simply coat or press ink in each originally designed color onto each overprint stamp or inks of different colors, and perform an overprint onto the same block or the same position of a desired object. Although the inks used for stamping are different, a color harmonic effect can be produced. The main purposes of color separation and screening are to decompose surface pattern of different colors. More importantly, many tiny mesh points are produced, and an appropriate blank space is reserved around the periphery of each mesh point, such that the light and dark layers of colors can be produced even if the viscosity of the ink is poor, or the pressed block is not humidified, or the ink has a too-strong or too-weak coverability, such that the same ink can be used for producing deep, shallow, dark and light layers of colors through the different sizes of mesh points. The invention further provides spaces of filling in overprint inks for the second, third or even fourth time.

Another interesting point of the present invention is that each overprint color-separation stamp is pressed with different or uniform forces and the ink pad is not even uniform at each corner, so that some of the inks are overlapped, and the visual illusion, the visual harmony, and the precision tolerance of each overprint color-separation stamp overprint may have a slight difference, and such difference gives rise to diversified changes, and the ink of each color is coated with different forces and consumptions and a different pressing method. Therefore, each pressing point is different, and thus creating the biggest difference between the present invention and printing, and the most interesting point of the present invention. Users can change the printing sequence or the color sequence according to the personal preference to give more fun.
While the invention has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the invention set forth in the claims. In summation of the description above, the present invention improves over the prior art, and complies with the patent application requirements, and thus is duly file for patent application.
