Recently, braille is written in various place as part of making to barrier-free. The number of products which is written in Braille or of bralle increase in the future. However, the package of the product requires low-cost and productivity. Therefore, the press working by the emboss method is more dominant than the screen print method to use special ink based of the cost and productivity. However, the necessary height of center of Braille is 0.3-0.5 mm. Therefore, a highly accurate bottom dead center control is needed for the press machine. Therefore, we designed the cam-toggle type of highly accurate press machine. In this actual experiment, investigating the influence that the polyurethane rubber gives to the braille emboss processability, and adjustment to the boxboard is experiment purpose.
