Day/Night Design
Color removal in day-night design describes a process where paint layers are selectively removed from parts, revealing the underlying material. When subsequently back-lit, only the laser-etched symbols are visible at night. The base material for day-night design is translucent or transparent plastic.
Complete switch consoles, as well as individual controls, can be processed. Therefore, laser marking in day-night design is often used in the automotive industry for marking controls. Here, these elements are intended to light up white during the day and in the car brand's specific colors at night.
Examples of laser marking in day/night design:
Automotive
Diverse controls in the car, such as the window control buttons or the hazard light button
Coffee machines
Coffee machine buttons
Telecommunications
Keyboards on phones or PCs
In day-night design processing, the laser represents the most rational, process-reliable, and often the only option.
A conventional pad printing process cannot create a day-night design because the illuminated area would remain covered by ink. Another advantage of laser marking over printing is its durability. Control elements, especially those used frequently, show signs of wear and tear very quickly. In contrast, laser marking in a day-night design is virtually indestructible.
