Description

[0001]
[Technical field to which the invention belongs]
The present invention relates to a decorating method in which lacquerware, lacquerware, and Buddhist objects are directly decorated or printed on an object to be painted by a computer-controlled inkjet printing method, and gold powder or gold foil is adhered thereon. Is.
[0002]
[Prior art]
Conventionally, when decorating lacquerware, lacquerware, and Buddhist ornaments with lacquer painting or lettering, the draft was drawn with brush or silk screen printing, and the painted surface of the draft was in a moderately dry state. At that time, gold powder was attached to the deer skin and was rubbed, or gold foil was pasted and fixed. On the other hand, due to the recent advancement of high-tech technology, automatic printing technology by personal computer control has been introduced to the decoration work that has been done manually by craftsmen as an area of traditional crafts.
[0003]
Further, the above prior art will be specifically described. First, Japanese Patent Application Laid-Open No. Hei 8-84656 discloses “Manufacturing method and its position”. Here, the present invention relates to a method for manufacturing a rank that can include a name that matches the quality and severity as a rank, while omitting the process of placing the name by hand carving or handwriting. The gist is to create a name and other characters, figures, etc. on a silk screen with a computer, print the name using a lacquer on the surface of the silk screen, and then apply the gold powder before drying the lacquer. The gold powder was fixed in the form of the name.
[0004]
Further specific examples are described in JP-A-10-309894, “Method of applying gold foil or gold powder”. Here, the present invention relates to a method for easily and inexpensively applying gold foil or gold powder to various products such as Buddhist wares, furniture, decorations, tableware, etc. The first gist of the present invention is to use UV ink The process of creating the base of the character or design, the step of drying the base so that the adhesive property of the UV ink is not lost, and the step of placing gold foil or gold powder on the dried base, The second gist of the invention described above is the step of creating a character or pattern base using UV ink, and the step of drying the base to a state where the adhesive property of the UV ink is not lost. Then, a golden character or a pattern was created by a step of placing a gold foil or gold powder on the dried base and a step of forming a transparent film on the surface of the gold foil or gold powder.
[0005]
On the other hand, printing methods controlled by a personal computer have recently been introduced into various industrial fields. Here, an inkjet printer is widely known as the printing method. The structure of this ink jet printer is very simple. The main parts are an ink jet head and ink and an ink container (ink cartridge). As a printing mechanism, a mechanism for feeding a printing medium in a vertical sub-scanning direction and a print head are arranged on the left and right sides. It consists of a mechanism that moves in the main scanning direction. Next, a characteristic of the ink jet printer is that ink is ejected from the ink jet head to the printing material, and printing is performed by the ink that has landed on the printing material penetrating and fixing. Here, as a method of ejecting ink onto the printing medium, a piezoelectric element that expands and contracts when a voltage is applied, an on-demand piezo element drive system that controls the voltage and ejects ink, an electromagnetic valve An on-demand valve system that controls the ejection of ink by opening and closing, and for the ink supplied under pressure by the pump, a constant vibration is applied by the piezo element when ejected so that the ink is ejected as fine ink droplets, and the ink is printed according to the print signal There are known a continuous type and a charge driving method in which droplets are charged and influenced by an electric field while passing between deflection electrodes, and the trajectory shifts to eject ink droplets toward a printing target.
[0006]
[Problems to be solved by the invention]
By the way, conventionally, a high-class feeling is demanded for the decoration of lacquer ware, porcelain ware, and Buddhist wares, and high-quality products are said to be hand-written by craftsmen. However, due to the problems of aging craftsmen with outstanding skills and lack of successors, the writing by craftsmen has the disadvantage that it is not limited or popular.
[0007]
In addition, those using silk screen printing technology, such as “Manufacturing method and its position” in Japanese Patent Laid-Open No. 8-84656, are industrially productive, but require plate-making, and can be printed like a name. There was a problem that it was not reasonable because it was one product and one version.
[0008]
Further, as described in JP-A-10-309894 “Method of applying gold foil or gold powder”, a method for creating a background of a character or a pattern using UV ink is also suitable for silk screen printing, writing with a UV ink, or The base of the gold foil letter or the pattern is created by the painting method, and the base made by this is formed into a raw dry state by a UV dryer, and then the gold foil or gold powder is placed on it and pressed and pasted. It is. Here, the UV ink used in the above method is known as a special paint that is instantly cured by irradiation with ultraviolet rays to form a hard film, but has a property that the viscosity change is large due to high and low temperatures, Since this change in viscosity has a great influence on printability and film thickness, it may be desired to adjust the room temperature in the workplace to a constant temperature. On the other hand, it is necessary to create a positive printing plate using an OHP film or the like on a personal computer or word processor as described in the examples of this UV ink. was there.
[0009]
Therefore, the present invention has been made in view of the drawbacks described in the above-mentioned prior art section, and the object of the present invention is not to prepare a required printing plate in advance like silk screen printing, and a personal computer. Characters and patterns can be drafted directly on the object to be coated by the ink jet printing method under control, and after the printing, a drying process is performed by a humidifying dryer, and gold powder is applied or a gold foil is applied immediately before touch drying. The object is to provide a decoration method by ink-jet printing of lacquer ware, lacquerware and Buddhist ware suitable for mass production.
