In "Exhibition Report of Converting Technology Exhibition 2018", we exhibited at "3Decotech Expo 2018" having the theme of technology and materials which provide design property and functionality of products.
This time, we introduced our latest printing and ink technology by focusing on High Definition Ink System (High Quality and High Definition Screen Printing Ink).
Period: April 05 - 07, 2018
Venue: Tokyo Big Sight

High Definition Ink system enables printing 100µm fine line like a hair with 100µm to 116µm accuracy. It also stably provides 100µm dot diameter of gradation. As a result, it can print expressions and designs beautifully with high resolution that was impossible in conventional screen printing.
Conventional ink requires to change printing conditions and stencils because printing condition varies depending on solid printing, gradation and fine lines and that causes cost increase. However, High Definition Ink system is able to print solid printing, gradation and fine lines at the same time. Thanks to that, we can achieve both improvement of decorativeness and cost reduction.
High Definition Ink system also shows its strength in solid printing. It creates beautiful solid printing without unevenness on functional ink such as metallic, pearl, mat and AG (anti-glare), which easily make unevenness occur in conventional ink.
It is possible to print beautiful straight line and true circle without concavo-convex and beautiful outline letter with less than 10µm saw edge.
Continuous Printability achieves both improvement of production efficiency and reduction of defective rate. It enables both printing fine lines with 100µm to 116µm of line and space, and 1500 sheets of continuous printing
It enables both fine printing with 100µm to 116µm of line and space and high speed printing at 800 to 1500 sheets/hour with cylinder press.
Re-printing is possible even if ink is left for 1 hour on the stencil. Working property such as reducing time of interruption of printing operation improves drastically.
Conventional ink requires stencil cleaning about every 20 minutes depending on the printing contents. However, High Definition Ink system requires stencil cleaning only once every 90 minutes even printing fine design.
In general, when color illustrations and photographs are printed by screen printing, they are printed after color was separated and laid over according to hue of image. Therefore, the more color numbers make number of stencils and processes increase and that causes cost increase.
However, as High Definition Ink for color separation can reproduce high definition image even 4 colors, it can reduce number of stencils and processes and it can print colored illustration images and photo images at low cost.
Colored decoration products, high definition image printing
Film Insert Molding (FIM) is also called In-Mold Decoration (IMD). The method that screen printed film is inserted into a mold to decorate molded products by integrated molding.
FIM/IMD can decorate with multiple color, fine lines and gradation which are difficult in painting. It is also excellent for durability and productivity (reduction of number of components and dealing with small lot).
PP resin is applied to various industrial products as it has low specific gravity and high strength. FIM/IMD can decorate on PP resin molded products which were difficult in the past.
1) Realize weight saving and strengthening.
2) Excellent decoration and efficiency than PP resin and vinyl chloride sticker.

Accuracy improvement of sensing function is essential for self-driving of vehicle and automation of various products by AI. Ink for sensor helps various types of sensors with high definition and preventing malfunctioning.
1) Possible to select and limit wavelength to be transmitted based on the type of sensor.
(Prevent intrusion of unintended wavelength light and reduce sensor malfunction.)
2) Excellent smoothness (leveling) of printed ink layer prevents malfunctioning due to diffuse reflection.
3) Possible to conceal the sensor receiver by reflecting visual ray.
(Achieve both function and decorativeness, and can be applied to security purpose.)
Sensor for self-driving, sensor for automation of various devices, sensor for automation of factory and facilities, and sensor for security purpose (entrance control and personal authentication, etc.)
Providing anti-slip function on home appliances and housing of electric devices can enhance grip force during use of the product, improve usability of product and prevent a falling accident.
Home appliances, and smartphones
As substitution for metal plating, mirror ink has advantage in cost and it can be applied to home appliances, mobile phones, automobiles, etc. Moreover, it can also be applied to optical instrument and component of electric device by utilizing light reflectivity of mirror surface.
1) Excellent mirror surface formation: Enables making printed ink layer of clear mirror
surface without unevenness.
2) Excellent printability: Excellent printability and suitable for outline and convex characters.
3) Environmentally friendly: Mirror ink does not contain hazardous substance and vinyl chloride resin.
(Comparing to metal plating, mirror ink is more environmental safety and can reduce cost for environmental measures.)
4) Application of optical function: Light reflectivity of mirror surface can be applied to components of optical and electronic equipment.
