Beta Opa-Dens Hand Held Ink Opacity Meter The quality of color graphics printed on clear film is highly dependent upon the white ink background. The white background enhances the chroma of colors, improves the readability of bar codes or QR codes and helps meet target color specifications. Color ink quality specifications are widely understood and measured with industry-standardized instruments and techniques. White Ink Opacity Measurement White ink specifications require different instruments and techniques in order to obtain accurate and actionable measurements. The quality of the white ink layer can be measured by two criteria: The opacity or hiding-power of the white ink layer The homogeneity or smoothness of the white ink layer The OPADENS measures the opacity in relation to a white reference (100% opacity) and a black reference (100% transparent equal to 0% opacity) A black surface absorbs all light such that no light will be reflected and reach the sensor ofthe device.
