How Colour Management Improves Packaging Sustainability

Sustainability is one of the defining commercial and ethical challenges of modern packaging production. Brand owners are under pressure from consumers, regulators, and investors to reduce the environmental footprint of their packaging - reducing material consumption, cutting waste to landfill, and improving the resource efficiency of their production processes. What is not always recognised is that effective colour management is a direct contributor to all of these sustainability goals. When colour is controlled systematically with X-Rite measurement instruments, the result is less waste, less rework, and more efficient use of every resource that goes into packaging production.

The most direct sustainability benefit of colour measurement is waste reduction. Every metre of printed packaging film, every sheet of printed board, and every moulded component that fails colour inspection and cannot be shipped represents the complete environmental footprint of that material - substrate, ink, energy, water, and labour - written off as waste. When colour measurement catches deviations early and enables correction before significant non-conforming material accumulates, this environmental waste is prevented. The waste reduction benefits of systematic X-Rite measurement are the same waste reductions that appear in sustainability reports and environmental certifications - making colour management a legitimate contributor to sustainability KPIs.

Makeready waste in packaging printing - the substrate consumed during press setup before colour is brought to specification - has a significant environmental footprint at scale. A packaging converter producing millions of units per year across dozens of jobs may consume substantial quantities of film, board, and ink in makeready before a single sellable unit is produced. Measurement-guided makeready, using an eXact 2 spectrophotometer to achieve colour targets in fewer iterations, reduces this makeready footprint systematically. The sustainability improvement is real, recurring, and documentable - the kind of evidence-based environmental performance improvement that brand owners and certification programs value. The X-Rite range is available through Seaga Group in Australia.

Ink and Chemical Consumption

Colour management also reduces ink and pigment consumption beyond the waste prevented by fewer rejects. In flexographic and gravure printing, precise colour control allows converters to run ink systems at optimised viscosity and density - neither over-inking to compensate for process variability nor under-inking and producing colour that is too light. When ink density is managed to a measured target rather than a visual impression, ink consumption is more predictable and controllable, and the tendency to add more ink "to be safe" is replaced by measurement-guided precision that uses exactly the ink needed to hit the target.

In plastics colour formulation, measurement-guided formulation reduces the number of trial batches needed to achieve a colour match - each trial batch that is not needed is a quantity of polymer, pigment, and energy not consumed. Over the course of a year's colour development work for a plastics manufacturer, the cumulative raw material and energy saving from reduced formulation iterations is meaningful both financially and environmentally. Handheld spectrophotometers like the Ci64 provide the measurement guidance for this efficient formulation approach in plastics colour laboratories.

Supporting Circular Economy Packaging

Sustainable packaging increasingly involves the use of recycled, bio-based, and alternative substrates that present new colour management challenges. Recycled content substrates have variable and sometimes unpredictable optical properties - variable whiteness, surface characteristics, and fluorescent brightener content - that affect how printed colour appears. Managing colour on these variable substrates requires more careful measurement, not less, because the colour target needs to be achieved against a changing substrate baseline.

X-Rite's measurement approach handles recycled and alternative substrates without difficulty - measuring colour in absolute L*a*b* terms against the brand's target, regardless of the substrate type. The ISO 13655 M1 measurement condition supported by the eXact 2 spectrophotometer correctly handles the optical brightener variability that complicates colour measurement on recycled and mixed-fibre substrates, ensuring that measurements on these sustainability-driven substrates are as reliable as measurements on conventional materials.

Color iQC software supports sustainability reporting by providing the production measurement data that quality and sustainability teams can use to document waste reduction achievements - showing the proportion of production meeting first-pass colour approval, tracking makeready waste reduction trends, and demonstrating the continuous improvement in colour quality efficiency that sustainable production programs require.

Conclusion

Effective colour management and packaging sustainability are aligned goals rather than competing priorities. When colour is managed systematically with X-Rite measurement instruments, the result is less waste, lower material and ink consumption, fewer rejects, and more efficient use of every resource in the packaging production process. For packaging businesses building sustainability programs that are backed by measurable evidence rather than aspirational claims, investment in colour measurement is an investment in genuine, documentable environmental performance improvement.
