Statistics and averages may not be a part your typical dinner conversation, but these concepts play a big part in the appearance of many of the foods we eat, as well as other household products and goods. Many food items, such as baked goods, fruits, and vegetables exhibit color variations in product development and processing. Color variations are also commonplace in household materials such as laminate wood flooring, textured or patterned carpeting, and other various building materials. Trying to create visual color consistencies in these types of products can present a real challenge, but finding average sample measurements with spectrophotometric analysis allows for color stability and consistency between batches and across various manufacturing locations.

Creating an average for product consistency and quality

Creating an average for color measurement in your product requires multiple readings that are calculated together to account for color variations. The best way to achieve accurate results is by choosing instrumentation that has a large sample viewing area and measures color the same way as it is seen by the human eye. Using human-eye technology and multiple readings, a color average can be determined and then quantified using the spectral data to allow for repeatability within the production process and between processing plants. This is highly beneficial when production occurs throughout various parts of the country or in other regions around the world. Using the same instrumentation for color measurement and setting the standards for color variations leads to product consistency and quality, no matter where the product is developed.

Using Spectrophotometric Technology 

Obtaining accurate color averages for products with color variations requires the use of advanced spectrophotometers. Choosing the right instrumentation is an important factor in producing quality products with consistent results. Thanks to advancements in spectrophotometric analysis and technology, modern instrumentation options allow for portability and come with a variety of viewing options specifically intended for various sample types, such as powdered or liquid, and transparent, translucent, or opaque. Spherical technology also accounts for color variations due to texture and the haze values that may interfere with standard color analysis.

The ability to view these sample types effectively requires the right geometric design elements and proper viewing angles. These measurements are catered to specific industry and product needs and are often required to meet the regulatory standards of the ASTM (American Society for Testing Materials), the FDA (Food and Drug Administration), the USDA (United States Department of Agriculture), or the EPA (Environmental Protection Agency).

In addition to meeting regulatory standards, spectrophotometers also aid in the detection of processing errors using real-time monitoring techniques. Benchtop, hand-held, and on-line spectrophotometers are all effective in catching color variations at their source and allowing for proper adjustments during the processing phases, which can increase efficiency and lower operational costs. When changes are made during this phase of processing, fewer products are wasted due to errors and regulation standards can be achieved more consistently.
