• Precise Colour Measurement for Black Products

    Quantify the nuances of deep black using the indices Blackness, Jetness and Undertone

    Black Products on a Black glossy background

Desirable products and high-end design often utilise deep black as a sign of quality, the versatility and timelessness of black has long made it popular with consumers. Black is also commonly used in devices such as personal electronics, computers etc, where the ability to create a sleek and consistent look with the inherent colour of the display technology is prized and the broad appeal of black as a neutral colour is popular for versatility in our daily lives.

Neutral colours though can create problems in colour consistency, as even small changes in hue can be easier to spot, potentially causing issues in matched parts or batch consistency. Accurate specification and control of black pigments and products is achieved through traceable and accurate colour measurement systems, reducing the reliance on subjective visual assessments and allowing colour matching to be more time and material efficient.

Additional colour indexes Blackness, Jetness and Undertone help producers to quantify and control for nuances in black products. This ensures that even in these low chroma tones products remain visually consistent to the customer and within specification. Accurate colour measurement and control of black products will therefore help producers to work effectively with suppliers and other stakeholders, reducing time and material waste to specify, produce and approve black plastics, black coatings, black textiles and more.

Benefits of Konica Minolta Sensing Solutions for Measurement of Black Coloured Products

  • Precision measuring black shades will improve the efficiency of working with suppliers and customers, agreeing specification and tolerances on black products that are both clear and realistic
  • Reduce wasted time and materials by operating with quantifiable data that focusses on the nuances in black shades instead of subjective assessments
  • Deliver a product that customers will perceive as quality high value by consistently producing visually impressive rich deep black shades

Read the Application note

Konica Minolta's application note Setting a New Standard for Black details the instruments that can be used to achieve the most accurate colour data for Black shades, both portable and benchtop devices and with both 45°/0° or d8 geometry to ensure that your workflow and your sample types can be repeatably measured.

Case Studies for the Measurement of Black Colours

Excellence in Black Plastics at Orion Engineered Carbons Ltd

The specific black measurement indices are used to differentiate between the 5 different carbon black products of Orion Engineered Carbons Ltd offering improved precision over standard methodology.

Improved low reflectance repeatability with the CM-17d

The CM-17d delivers improved repeatability for black tones even over the previous generation (CM-700d) using the 3 indices of Blackness, Jetness and Undertone, blacks under 5% reflectance can be more accurately characterised.
