Problems solved by technology

However, since the metal photo 8 utilizes brightness contrast to express patterns, the use of a metal printer to produce the metal photo 8 requires professional processing of the image file to be produced, such as adjusting the color difference and contrast of the image, especially if the pattern is relatively dark. Complicated landscape or portrait photos, otherwise the resulting metal photo will not show its due characteristics due to lack of contrast
In addition, because the metal photo 8 uses neatly arranged pits to show the difference in brightness of the pattern, and larger and deeper pits are required to express the higher parts of the pattern, the metal photo 8 produced by the metal printer cannot express high resolution pattern
[0006] In view of the fact that the prior art has the shortcomings of being unsuitable for making a small amount of metal photos or having poor resolution, it is necessary to provide a method that can make a small amount of high-resolution metal photos.

Embodiment Construction

[0019] see Figure 4 to Figure 7 , Figure 4 to Figure 7 It is a schematic diagram of a method for making a metal photo according to a preferred embodiment of the present invention. Such as Figure 4 As shown, firstly, a substrate 10 is provided, and a photoresist layer 12 is coated on one surface of the substrate 10 . Wherein, the substrate 10 can be a glass substrate or other insulating substrates, and the material of the photoresist layer 12 can be selected from wet photoresist or dry film photoresist depending on the actual situation. In addition, the photoresist layer 12 may also use a positive or negative photoresist as required, depending on the pattern on the photomask or negative used subsequently, or according to the pattern transfer times of the finished product. Form the correct pattern on the finished product.

[0020] Such as Figure 5 As shown, a patterned negative 14 is then used as a photomask to perform an exposure and development process to form a photo...

Abstract

The invention provides a method for making a metal photo, firstly providing a substrate and coating a photoresist layer on the substrate, successively using a light mask with a picture to perform an exposing and developing manufacturing technique so as to patternize the photoresist layer, and finally using the electromechanical LIGA technique to form a film layer on the substrate and the pattern at the photoresist layer, where the film layer has a picture corresponding to the light mask.

Description

technical field [0001] The invention relates to a method for making a metal photo, in particular to a method for making a metal photo by using micro-electromechanical LIGA technology. Background technique [0002] Metallic photo is a very popular product in recent years. It differs from traditional photo paper photo in that metal photo uses a metal film instead of traditional photo paper, and then forms patterns of different shades on the surface of the metal film. Because the different depths of the surface of the metal film will change the reflection angle of the light, it can show patterns such as portraits or landscapes through the change of brightness, and at the same time use the shiny metal photo of the metal material to show the image different from the traditional photo. Style and texture. [0003] Existing metal photos are mainly produced by metal printing technology, and its principle is similar to that of general printing technology, that is, using appropriate p...
