...inted with a screen ink. Due to its good printing properties fine line details as well as areas can be printed. Taking regard of the pigment particle size a screen mesh size of 77 to 120 fibers per cm is recommended. The new version of the Rainbow Ink effect coating is available in four variations. They are solvent based metallic inks for producing rainbow like effects and are also used successfully in IMD applications. If the ink is reverse printed on the rear side the rainbow effect is noticea...

...ures in the component surface with a “depth” of just a few nanometers create a hologram-like interference effect (Fig. 2). Incident light is diffracted by the grid and makes inions, logos or even images gleam in all hues of the rainbow. As this effect is an integral part of the product, the purchaser is able to distinguish the original from the copy with the naked eye. The grid structure itself is engraved on special steel inserts that can be integrated easily into injectio...

...esolved structure in, for example, a plastic surface. Holograms of this type absorb the entire spectrum of incoming light and diffract it so that it is diffused into its individual spectral components. The holographic image therefore shimmers in rainbow colors when viewed. Embossed holograms acquire their typical appearance through reflective metallization, which brightens the image. It is characteristic of these holograms that they only appear in true colors with ideal illumination and even the...

...d the MyWave-3D is an optical waveguide with scattering pigments that is formed for a correctly angled illumination similar to the part surfaces, RGB LEDs are mounted next to it. These redgreen-blue LEDs can show all the colors of the rainbow. If you stroke your finger lightly over the volume controller printed on the part surface, the text changes color. When you have reached the desired color, you take your finger away and the color remains. The capacitive field can be adjusted so that it is n...

...o phase boundary can be detected between the reactive system and PMMA substrate, since the reactive system interpenetrates with the substrate during the process and is firmly anchored. The coating produces no optical distortions or undesirable rainbow effects, either, since it has the same refractive index as the PMMA substrate to the third decimal point. Optical interference and associated rainbow effects are therefore prevented. Test Series The process is therefore able to provide a scratch-re...

...son does not just see a color, he feels and even smells it [2]. Since time immemorial, people have felt a special fascination for colors, some have actually dedicated decades of their lives to them, e. g., Isaac Newton, who explained the rainbow, or Goethe, who occupied himself for half of his life with the question of colors. He felt his extensive color theory was his most important accomplishment [3, 4]. When we further consider the innumerable poets and painters who were inspired by colors, t...

...ve system penetrates into the substrate and is firmly anchored to it by chemical bonds. This surface continuity and the well matched refractive indices of the coating and plastic prevent optical interference that would be manifested as undesirable rainbow effects on the surface.Tailored to Each OtherIn the CoverForm process (Fig. 2), PMMA is injected into the mold cavity and compressed (injection compressing molding). After a short cooling phase to consolidate the thermoplastic, the cavity is ex...
