①Technical Overview | Product Specifications

The gimmick of changing the viewing angle of the bellows fold to create a different design has been around for a long time.

 
(Example)
Lenticular printing

BELLOWS PRINT is a printing technology that reproduces the above bellows gimmick in the microscopic world, and is a patented product that uses special data processing that can be achieved by printing with layers of UV-curable ink.

In recent years, with the advent of UV printers, 2.5D (thick) printing has become easier, and BELLOWS PRINT was born.

Thick printing, which creates an uneven surface by printing with multiple layers of UV ink that hardens instantly when exposed to UV light.

Since this is a sign and display product, it is necessary to use a 2D flatbed printer instead of a 3D printer which has a slower production speed. However, it was difficult to establish production with 2D flatbed printers because the print head could not move in the height direction and there were limitations in the ability to process different layers of data.SO-KEN has developed a special data creation method to overcome the aforementioned issues and has succeeded in establishing BELLOWS PRINT production.

②Notes on installation and use

How it looks depending on the structure

The surface has regular unevenness. The two types of patterns printed on the bottom are thinned out and the convexity is used to adjust the visible area.

How it looks from the left side / How it looks from the front (the left and right patterns appear to be mixed) / How it looks from the right side

Visibility pattern

The two designs are interchangeable when viewed from certain angles.

View from the left side

It looks like a red design.

View from the front

It appears to be a mixture of both red and blue designs.

View from the right side

It looks like a blue design.

About angles

The angle at which you can almost see only one design is about 38°, and after 38°, the design overlaps with the other design, making a 5:5 ratio at the center.There will be an error depending on the color and design.
