Align Laboratory and Production Color Measurements Across Plastics Operations

Plastics suppliers and masterbatchers often develop and validate color recipes in a central laboratory using benchtop spectrophotometers. Once those recipes move into production, teams typically rely on portable spectrophotometers for day-to-day quality control across multiple facilities.

When laboratory and production measurements do not align closely, even established quality procedures can leave teams reconciling differences. The challenge becomes more pronounced with high-chroma colors, translucent materials, textured parts, and plastics measured under varying temperature conditions. Maintaining color consistency therefore depends on a measurement workflow that connects laboratory standards with practical production control.

Challenges

Differences between benchtop and portable spectrophotometers can produce varying results, particularly for high-chroma colors, translucent materials, and complex plastic components. Surface texture, additives such as optical brighteners, and temperature-related color shifts can introduce further variation, making repeatable measurement across sites more difficult. For example, a molded part measured immediately after production may produce a different reading than the same part measured later in a temperature-controlled laboratory.

• Additional time spent validating and reconciling measurements
• Back-and-forth communication between laboratory and production teams
• Uncertainty when determining whether a batch meets tolerance
• Inconsistent decisions across facilities and operators
• Greater business risk when customers have tight tolerances

Solution

A portable sphere spectrophotometer aligned with benchtop instruments can reduce measurement gaps without requiring benchtop devices at every production site.

Spectura S64 delivers measurements closer to Ci7800 results than legacy portable devices, especially for critical colors and challenging plastics. Multi-aperture flexibility supports varied part sizes and shapes, camera-assisted targeting improves consistency, and NetProfiler helps maintain instrument alignment across sites.

Together, these capabilities help plastics suppliers and masterbatchers improve confidence, reduce delays, and make more consistent color decisions across facilities.

Results

• Reduce measurement uncertainty across facilities
• Improve consistency for high-chroma colors and complex plastic materials
• Minimize repeated checks between laboratory and production teams
• Make more confident pass/fail decisions against customer tolerances
• Reduce retesting caused by temperature-related color variation
• Simplify daily operation with easier, less frequent calibration
• Support faster onboarding and more consistent instrument use

How it Works

1. The lab technician develops the plastic color recipe in Color iMatch using a Ci7800 for precise color formulation.
2. The technician measures and approves the color using a Ci7800 benchtop spectrophotometer.
3. The lab shares the approved target and standardized measurement procedure with production facilities via Color iMatch/Color iQC.
4. The QC Manager uses the Spectura S64 paired with Color iQC for incoming inspection of pellets.
5. The Production operator uses the Spectura S64 for portable quality control inspection on pellets, plaques, molded parts, or extruded components throughout the production cycle, evaluating against approved laboratory standard in Color iQC.
6. The QC and Production teams perform routine instrument checks with NetProfiler and consistent workflows to maintain alignment across sites.

Featured Products

Spectura
Portable sphere spectrophotometer that helps plastics manufacturers bring production measurements closer to laboratory standards, reduce variation across sites, and make faster, more consistent color decisions.

Ci7800
Offers precise measurement for both translucent and transparent plastics.

Color iMatch
Advanced formulation engine for optimal matches and workflow efficiency.

Color iQC
Quality control software that connects color measurement data to actionable quality insights, helping extrusion teams achieve more consistent color and faster approvals.

NetProfiler

For global plastics suppliers and masterbatchers, consistent color depends on more than precise laboratory formulation. Production teams also need measurements they can trust across instruments, materials, operators, and facilities.

Spectura helps bring portable production measurements closer to benchtop standards while simplifying routine calibration and use. With added support for temperature-related color correction, teams can make more reliable decisions regardless of where measurements take place. The result is a more connected quality workflow that can reduce uncertainty and help teams maintain color consistency from the laboratory to the production floor.
