Growing requirements for sustainable production, the use of recycled materials, and shorter time to market are creating new challenges for the plastics industry. One area that has a significant impact on both production costs and a company’s environmental footprint is color management.
Traditional methods of color development and approval often rely on physical samples, multiple iterations, and subjective visual assessment. As a result, this process can be time-consuming, costly, and generate significant amounts of waste. However, more and more plastics manufacturers, masterbatch producers, extruders, and processors are recognizing the potential of digital color management as a way to increase efficiency and reduce losses.
Color as a hidden source of costs
In many companies, the color approval process follows a familiar pattern: design, formulation, sample preparation, shipment to the customer, feedback, corrections, and renewed sample preparation. This "closed color loop" may be repeated many times, involving laboratories, quality departments, logistics, and customers.
An additional complication is that prototypes do not always reflect the actual appearance of the final product. They are often made using different technologies, on simplified shapes, or with materials that differ from those used in serial production. As a result, an approved color may look different once production starts, leading to misunderstandings, complaints, and further corrections.
This becomes particularly evident in the case of recycled materials, whose properties may vary between suppliers and raw material batches. Maintaining color consistency then requires much greater process control than in the case of virgin materials.
Digital data instead of physical samples
A modern approach to color management is based on the use of spectral data acquired with spectrophotometers. Instead of sending numerous samples between participants in the supply chain, it becomes possible to share precise digital data describing the color together with acceptable tolerances.
Such a solution already makes it possible at the design stage to create digital color libraries and build color palettes based on actual measurements. Designers can use tools that allow them to capture color inspiration and quickly assign specific standards to it.
The next step is the virtualization of material appearance. Thanks to digital models, it is possible to generate realistic 3D visualizations that take into account not only the color itself, but also pearlescent and metallic effects, surface texture, and the degree of plastic transparency. This makes it possible to predict the product’s appearance even before the first production trials are carried out.
Faster formulation and less waste
The benefits of digitalization are particularly visible in the color formulation process. Software using spectral data makes it possible to calculate formulations quickly and reduce the number of trials needed to achieve the required shade.
For masterbatch producers, this means shorter development times for new colors, lower pigment consumption, and fewer samples sent to customers. As a result, costs, transport-related emissions, and the amount of waste generated during successive formulation corrections are reduced.
The ability to use data obtained from measurements of recycled materials is also important. This makes it possible to predict raw material behavior in the production process more accurately and compensate more effectively for its natural color variability.
Real-time quality control
Digital color management does not end at the formulation development stage. Real-time monitoring of the production process is playing an increasingly important role.
Inline measurement systems using non-contact spectrophotometers enable continuous monitoring of color parameters directly on the production line. If deviations from the specified parameters are detected, operators can take corrective action immediately, before large quantities of non-conforming products are produced.
Such solutions help reduce material losses, improve process stability, and increase production predictability. In addition, the data can be shared between production sites and partners in different locations, making it easier to maintain consistent quality standards across global supply chains.
Digital color supports sustainability
Plastics production is currently under strong pressure to reduce its environmental impact. The use of recycled materials is an important element of this strategy, but it is equally important to minimize losses arising during production processes.
Digitalizing color management helps reduce the number of physical samples, shorten the color approval process, cut production waste, and limit the need to transport samples between suppliers and customers. At the same time, it enables faster implementation of new products and improves the quality of finished products.
In the face of growing market expectations and increasingly complex supply chains, digital color management is becoming not only a tool for quality optimization, but also an important element in building competitiveness and achieving sustainability goals in the plastics industry.
