JP3106018U - Eyeglasses and eyeglass parts directly decorated with an inkjet printer - Google Patents

Abstract

An object of the present invention is to produce eyeglasses or eyeglass parts at high added value, high quality, and inexpensively.
A corona treatment is applied to an inner surface of a picture frame on which an uneven portion (diamond cut) on the surface of a left crane 1 is formed, and an undercoat liquid is partially applied. At this time, the background color was made silver by mixing the silver paste with the undercoat liquid. After drying with hot air at 60 ° C. for 5 minutes, it was left at room temperature. A desired pattern (red or green gradation pattern) was printed thereon by an ink jet printer (2880 dpi), dried with hot air at 60 ° C. for 5 minutes, and left at room temperature. Further, a clear resin solution containing a pseudo-cloisonne shimmer was applied and baked at 120 ° C. for 20 minutes to obtain a decoration having a depth of being studded with jewels.

Description

The present invention relates to spectacles and spectacle parts which are directly printed and decorated with a desired color or pattern using an ink jet printer.

In the past, when trying to put a logo or color pattern on the glasses, if it was a rough pattern, it was done by hand dyeing or pseudo-cloisonne. For single or two-color printing, high-precision silk screen or pad printing is used. Although it is expensive, it is not often done, but it is possible to apply multi-layer processing such as patterning by applying multilayer processing such as painting, plating, ion plating, etc. partially by masking processing.
Complex colors and patterns are mainly performed by thermal transfer techniques.

First of all, it is necessary to digitize patterns and output them digitally in order to eliminate variations in patterns themselves due to manual work.

Even though silk screen and pad printing have advanced to digital DTP, it is only up to plate making, and color separation is required for each color. In the case of multi-color printing, the positioning of the plate becomes quite difficult work, and labor is saved. In view of printing accuracy, a printing system that does not require a plate is considered necessary.

Surface treatments such as two-color plating, painting, and ion plating using masking are each expensive, and complicated patterns and multi-colored ones are not possible, so an inexpensive and realistic processing method is considered necessary. Can be

In the case of transfer that is generally performed for decorating complex and diverse patterns, the molded transfer product becomes less versatile, and thermal transfer to the product after molding involves manual work in attaching, The disadvantage is that uniform transfer is difficult, and it is necessary to produce a certain amount of material such as film or roll-shaped transfer paper, making it difficult to respond to small-lot trial production.

There is also a hydraulic transfer that can be transferred to three-dimensional objects, but in the case of spring hinges often used in eyeglass frames in recent years, it is inconvenient to submerge, and the hydraulic It can be said that this is an unsuitable industrial product.

We create printable digital data to improve the accuracy and uniformity of the pattern itself, and to easily manage it. At this time, it is possible to easily import the base data from a digital camera or a commercially available material data collection, making it possible to create advanced designs at low cost. The image is processed using commercially available drawing software and photo retouching software, and the output data is prepared by trimming it into the shape of the printing material.

In order to enhance the adhesion of the printing ink to the print site, which will be described later, we will perform base treatment and undercoat suitable for the material. Also, by mixing white ink or silver paste with the undercoat liquid at this time, it is possible to add a background color, and it is possible to maximize the color reproducibility of inkjet printing.

The surface of the print target area is printed using an ink-jet ink-jet printer that does not require physical individual materials such as plates or films, and can output the output data as it is to a three-dimensional object and uneven parts according to instructions from a personal computer. Ink is sprayed directly on to print. At this time, it is necessary to obtain the printing position accuracy by placing the non-printed material on a special jig molded with silicone or the like.

After printing, a top coat or pseudo-cloisonne resin solution is applied on the whole or part of the printed part mainly to improve abrasion resistance, water resistance, chemical resistance, weather resistance, etc.

According to the first aspect of the present invention, a variety of colors and high-definition patterns can be uniformly applied to the portions having the uneven portions by using the ink jet printing technique which has never been performed on the glasses and the eyeglass parts. It is possible to manufacture decorated products.
In addition, it is possible to respond quickly and inexpensively to single-order products and small-lot prototypes without requiring additional materials such as plates and transfer paper.
In addition, by performing additional processing in the final manufacturing process, products with a wide variety of variations can be made with one mold, and the reduction of dead stock can be expected.

According to claim 2 of the present invention, it is possible to manufacture spectacles and spectacle parts which are decorated with a highly reproducible design with good adhesion to all materials and surface treatments.

According to claim 3 of the present invention, it is possible to manufacture spectacles and spectacle parts with three-dimensional design decoration.

The fourth aspect of the present invention mainly aims to increase the abrasion resistance of the ink printed according to the first aspect, but also has the effect of increasing the water resistance, chemical resistance, weather resistance, and the like.

[Example 1] A corona treatment was applied to the inner surface of a picture frame on which an uneven portion (diamond cut) on the surface of a left crane was formed, and an undercoat liquid was partially applied. At this time, the background color was made silver by mixing the silver paste with the undercoat liquid. After drying with hot air at 60 ° C. for 5 minutes, it was left at room temperature. A desired pattern (red or green gradation pattern) was printed thereon with an ink jet printer (2880 dpi) manufactured by Master Mind Co., Ltd., dried with hot air at 60 ° C. for 5 minutes, and left at room temperature. Further, a clear color resin liquid containing a simulated cloisonne is baked at 120 ° C. for 20 minutes to obtain a decoration with a deep gem-studded decoration.

[Example 2] An undercoat liquid is partially poured into the inner surface of the left modern concave portion. At this time, the background color was made pale by mixing the blue water-soluble ink with the undercoat liquid. After drying, the first pattern (coral picture) is directly printed by an ink jet printer. After drying, a clear undercoat liquid is partially applied thereon. After drying, the second pattern (picture of a tropical fish) is directly printed by an ink jet printer. After drying, a pale blue topcoat liquid is applied, and after drying, the surface is uniformly finished by polishing to obtain a picture-like three-dimensional decoration in a hydrogen carbonate.

The present invention relates to spectacles and spectacle parts which are directly decorated by using an ink jet printer capable of directly printing on a non-printed material which is a three-dimensional object, but also to a decorative article such as a watch, a belt and a ring. Available as well.
