A pigment or colourant is a material that changes the colour of reflected or transmitted light as a result of light being absorbed at a certain wavelength. Materials that humans have chosen and developed for use as pigments usually have special properties that make them useful for colouring other materials like paints.
A number of challenges arise when making a pigment or colourant. The pigment needs to be strong enough to react with the material it will be added to. In the painting industry, the pigment gives the paint it’s unique colour. Different pigments are mixed in different quantities to create the extensive range of paint colours.
Colour measurement is vital in the creation, production and formulation of new pigments. If a pigment is made with inferior quality materials this will affect the look of the paint. Some of the challenges faced when creating pigments include ensuring that an authentic pigment is used, the pigment reacts when to different substances and the pigments mixes well with other colours which is useful in paint production and development.
Some of the challenges we can solve with colour measurement for Pigments and colourants are:
- Measuring the colour of pigments to ensure consistency and quality control
- Identify adulteration or contamination of pigments or colourants
- Manage and control the colour of pigments during production
- Ensure that pigments mix well with solvents and bases
- Save time and money during the formulation of new pigments
