PSS inks

The ink based on monodisperse polystyrene spheres dispersed in water allows the creation of images that change their color at different angles. This effect is created by creating a super-ordered diffraction grating on the surface.

Different colors of printed samples are achieved by changing the diameter of the polystyrene spheres.

Available in 3 diameters:

• 315 nm - violet at an angle of about 45 degrees
• 425 nm - green at an angle of about 45 degrees
• 550 nm - yellow at an angle of about 45 degrees
