METHODS FOR PRINTING IMAGES ON THE SURFACE OF CERAMIC OR POCELAIN ENAMELLED METAL PLATE USING LASER PRINTER TONER}

The present invention relates to a method of forming a porcelain or enamel surface pattern using a laser printer toner, and more particularly, to heat a laser printer toner adhered to a printing surface of a transfer paper to have viscosity; Applying a glaze powder of a specific primary color to the fixing surface of the toner, and laminating the transparent paper coated with a cover coat to perform laminating; Submerged in water to separate and dry the paper on the transfer paper; Removing paper components of the transparent paper and the transfer paper; Repeating the above operations for each chromaticity; The resultant of the present invention relates to a method of forming a surface pattern of porcelain or enamel plate using a laser printer toner, wherein the resultant is brought into close contact with the surface of the transfer body and the target is sintered at the melting point of the pigment glaze.

In general, there are a variety of methods for forming patterns on porcelain or enamel surfaces, the most typical of which is to sinter the pigment glaze on the porcelain surface using a brush or brush, The silk glaze ink is printed on the surface using a silk screen and then sintered.

The method of forming a pattern using the brush is a classic method, in which a potter directly sets a ceramic pattern and paints a pigment glaze according to the set pattern on a ceramic or enamel surface, and then, Allow to dry for over a period of time. Through such a process is completed by sintering dried ceramics or enamel.

However, the method of forming the pattern is a method used in the manufacture of authentic pottery, such as art, and has not been suitable for mass production of modern times. Until recently, the silk screen method has been recognized as a conventional method.

The pattern forming method according to the silk screen method is largely a process of manufacturing a transfer paper for producing a ceramic transfer paper of a pattern to be formed on the surface of the porcelain, and peeling the transfer film of the transfer paper to form a pattern layer by closely contacting the surface of the ceramic. It consists of a pattern transfer process and a firing process of high temperature firing the transferred ceramics.

In the process of manufacturing the transfer paper, the original, selected or original pattern of the selected pattern is color-separated by the primary color separation method, a film is produced for each of the decomposed primary colors, and a screen printing plate is produced for each primary color. For example, four screen printing plates are produced in the case of four color separation of natural patterns. The transfer paper for ceramics is manufactured by overprinting the transfer paper by the number of screen printing plates using the produced screen printing plate.

The pattern transfer process is applied by coating a material of synthetic resin (resin) on the overprinted transfer paper as described above, and coated so that the previously overprinted pigment is attached to the coating film, and the coating film of the coated transfer paper is separated It is the transfer process of pigments attached to the ceramic surface. The porcelain is then calcined at high temperature so that the pigment is calcined on the porcelain surface.

As described above, a method of forming a porcelain pattern using a transfer paper has a problem in that a large amount of costs are required to manufacture a transfer paper, and the resolution (about 140 / dpi) of the pattern falls. In addition, recently, an apparatus using an offset technology has been developed and attracting attention, but due to heavy equipment cost and low efficiency, it is not actively utilized.

In order to solve the above problems, the pigments of the color are applied to a plurality of transfer paper prints on which toner is attached to the surface, and then heat-treated, thereby responding to the desired pattern by the adhesiveness of the heated toner. A method of forming a ceramic or enamel surface surface pattern using a laser printer toner that is suitable for producing a small quantity of various varieties and provides a clearer pattern through a pigment deposition process has been reported (Domestic Patent No. 10-0275190).

Specifically, after acquiring an image of a pattern to be formed on a ceramic or enamel surface as digital information, using a digital signal processing means, the obtained image is decomposed into a predetermined number of primary colors and printed on the transfer paper for each of the decomposed chromaticities. A method of forming a surface pattern of a transfer object, comprising the steps of: A process of making a toner adhered to a printing surface of a transfer paper to have a viscosity, and applying a glaze powder of a specific primary color to a fixing surface of a toner having a viscosity; Bonding the printing surface of the transfer paper coated with the glaze powder and the surface of the transfer object with a specific adhesive, and then removing the paper component of the transfer paper and repeating the above B process, and sintering the transfer material at the melting point of the pigment glaze. It consists of a C process (see FIG. 1 ).

However, the above method has to produce an inverted image for each chromaticity, which is difficult to apply to curved surfaces. In addition, toxic chemicals such as adhesives may be used to harm the human body.

Therefore, the present inventors do not use an adhesive by using a ceramic or enamel surface pattern forming method including laminating a transparent paper coated with a cover coat and a transfer paper coated with glaze powder, and finally obtain an independent film form. The present invention was completed by finding that the transfer to the transfer object formed in the curved surface is easy and a high resolution pattern can be obtained.

If the producer wants to form a pattern on the surface of the ceramic or enamel plate, the image of the pattern to be formed on the surface of the ceramic or enamel is obtained as digital information (S101). At this time, the method of acquiring a digital image includes a method of photographing an image of a pattern to be printed with a digital camera, a method of scanning a film developed by photographing with a conventional camera using a film digital scanner, and a conventional method. The developed image taken by the camera is classified into a scanning method using a digital scanner.

The digital image information obtained through the process (S101) is input to a computer, and the computer displays the input image information on the CRT to identify a pattern to be printed by the producer. At this time, if the user wants to edit the image displayed on the CRT, the user manipulates the computer to display the desired image by operating the keyboard (S102).

When the desired image is displayed through the process (S102), it is decomposed into four colors or the required number of colors using the existing primary color separation method (S103).

Subsequently, the information decomposed in the primary colors in step S103 is printed in black and white on a sheet by a laser printer in correspondence with the number of decompositions (S104). The paper used at this time is a water transfer paper, and the water transfer paper refers to a transfer paper which separates the transfer object and paper by adding water. Therefore, if the primary color separated information in the primary color separation process (S103) is four colors, it is printed on the four transfer paper for each color.

The above process is the same as the conventional process, and the gist of the present invention is described below.

The first step (S105) is to make the laser printer toner viscous, and the toner is fixed to the part printed in black because the black paper is printed on the water transfer paper printed by the laser printer manufactured in S104. Heated with a heater to give viscosity to the toner adhered to the water transfer paper. At this time, the temperature for heating the water transfer paper in the heater is 110 ~ 185 ℃, the temperature is a temperature at which the toner adhered to the surface of the water transfer paper by the printing process is viscous, but the color of the water transfer paper does not occur.

The second step (S106) is to apply a glaze powder of a specific primary color on the surface of the fixed laser printer toner, and consists of two steps. The first step is spraying the conventional pigment glaze powder prepared in advance on the printing surface of the water transfer paper passed through the heater through the pigment glaze spreader. The second step is to remove the pigment glaze that has not adhered to the toner in the glaze sprayed on the printing surface on which the toner remains viscous by the unfixed glaze remover. At this time, a method of removing the unattached glaze powder is blown by blowing compressed air or mechanical vibration.

The third step (S107) is to perform the above process and to coat the cover coat on the transparent paper, the cover coat is a conventional resin (resin) used in general ceramics, in the present invention is coated on the transparent paper with a thickness of 5 ~ 120 ㎛ Let's do it. The transparent paper uses transparent glass or transparent synthetic resin.

In the fourth process (S108), the cover coat on the prepared transparent paper and the transfer paper to which the glaze of the second process is fixed are bonded to each other by laminating.

In the fifth process (S109), the transfer paper and the transparent paper, which are laminated and bound, are submerged in water to separate the paper portion of the transfer paper. As a result, the image information formed on the water transfer paper in the second process is transferred to the cover coat of the third process.

In the sixth process (S110), the separated transparent paper of the fifth process is dried, and the transfer paper having the different color of the second process fixed thereto is laminated with the transparent paper dried in the fifth process, and in the seventh process (S111) Repeat the sixth step as many colors as needed for the pattern.

In the eighth process S112 and the ninth process S113, paper components of the transparent paper and the transfer paper are removed from the resultant, respectively.

The resultant thus obtained is brought into close contact with a predetermined relative position of the transfer target in step S114, and the transfer target is sintered at the melting point of the pigment glaze.

In the method of forming the porcelain or enamel pattern using the laser printer toner of the present invention, unlike the conventional transfer of water transfer paper according to chromaticity using an adhesive, transfer paper having a complete color in advance using transparent paper is formed in the form of a film. It is possible to reduce the transfer step by manufacturing and transfer it, thereby saving the pattern formation time, it can reduce the cost. The transfer paper in the form of a film enables the transfer to various shapes of substrates, and can be transferred without the use of a toxic chemical adhesive, which does not harm the human body and reduces the generation of waste water. In addition, the transfer paper produced in accordance with the present invention can be printed in the forward direction, it was possible to obtain a pattern of high resolution at 1200 dpi of the conventional resolution of 150 dpi.

As described above, after acquiring an image of a pattern to be formed on a ceramic or enamel surface as digital information, the image obtained by using any digital signal processing means is decomposed into a predetermined number of primary colors, and transferred paper for each chromaticity decomposed. In the method for forming a transferee surface including a process of printing on the present invention, the present invention includes a very simple process of laminating a transparent paper and a transfer paper coated with a cover coat, thereby reducing manufacturing time and cost, and using an adhesive. You can make a pattern without it. In addition, it is manufactured in a film state can be used in the curved transfer object, can be printed in the forward direction to obtain a high-resolution pattern can be more excellently to form a pattern on the ceramic or enamel surface.
