Color control for print, labels & packaging

Verify spot colors, production runs and packaging color tolerances across substrates, converters and suppliers—with a method that separates ink, paper and surface effects.

Packaging material moving through a printing press

Why color drifts

A color target has to survive the substrate, press and finish.

Ink draw-downs, press sheets, labels and finished cartons can all carry the same nominal color and still measure differently. Paper whiteness, optical brighteners, ink film, coating, lamination and texture affect the result. Instrumented color control makes those variables visible before a run becomes waste.

01

Spot-color control

Approve standards and production color with L*a*b*, spectral data and an agreed color-difference formula.

02

Run-to-run consistency

Track color at defined positions and intervals so drift is corrected while the press is still running.

03

Supplier alignment

Give printers, converters and brand owners one measurement method for approvals, claims and repeat orders.

Instrument options

Portable and benchtop instruments for Print & Packaging

Portable instruments suit press-side checks, incoming packaging and large finished items. Benchtop instruments suit controlled laboratory presentation, small specimens, transmission work and repeatable approval workflows.

Where it pays off

Use cases across print and packaging production

01

Spot colors

Approve brand colors against a protected physical and digital standard.

02

Press make-ready

Reach the target faster by measuring early sheets before full production speed.

03

Run monitoring

Sample defined positions across the web or sheet and trend drift through the run.

04

Labels & cartons

Check converted pieces after coating, lamination, embossing and finishing.

05

Incoming packaging

Verify supplier cartons, labels, closures and printed components before use.

06

Multi-site standards

Correlate instruments and exchange spectral data between brands, printers and converters.

Method notes

Decisions that make measurement repeatable

DecisionCommon starting pointWhy it matters
SubstrateMeasure the approved stock or control its whiteness and backingPaper shade, opacity and brighteners can move both color and visual appearance.
GeometryKeep geometry and specular condition fixedGloss, coatings and texture respond differently under different optical arrangements.
ApertureFit fully inside the printed patchAn aperture that includes unprinted stock, edges or adjacent colors produces a mixed result.
ToleranceName the formula and component limitsA shared ΔE number is only enforceable when every site calculates it the same way.

UV control for paper and board

Many white papers and boards use optical brighteners. If they influence the approved appearance, define the UV condition and keep it consistent. The SD-700 UV is a relevant portable option where UV-included and UV-excluded comparison is required, but it is one option within the wider portable and benchtop ranges.

Specifying with confidence

Print & Packaging color measurement FAQ

Should print be measured on a press sheet or finished pack?

Use the specimen that controls the commercial decision. Press sheets are best for process adjustment; the finished pack confirms the effect of coating, lamination, texture and conversion. Many programmes define both.

Why does the same ink read differently on another paper?

The substrate changes reflected light through its color, opacity, fluorescence and surface. Keep the approved stock fixed or define how substrate variation is handled.

How large should a color patch be?

It must fully cover the instrument’s true viewed and illuminated areas with margin for positioning. Confirm those areas for the selected aperture rather than relying only on the aperture name.

Can suppliers share one Delta E limit?

Yes, after agreeing the standard, sample construction, instrument geometry, settings, formula and correlation process. The limit alone is not a complete specification.
