When a paint manufacturer launches a new colour range, the colour experience customers encounter fan decks in showrooms, swatch cards in stores, colour charts in brochures is almost certainly produced by a specialist colour sampling printer rather than the paint company’s own production facility. Colour sampling is a niche within a niche: it requires print capabilities that most commercial printers do not have, colour tolerances that most production workflows cannot achieve, and quality control processes that most print operations do not justify for standard commercial work.
We provide colour sampling services for paint manufacturers, coatings companies, colour system providers and architectural specification firms. This guide explains what is involved, what makes it different from standard print, and how to brief a sampling project effectively.
Key takeaways
- Colour sampling encompasses fan decks, swatch cards, colour charts, peel-and-stick chips, paint-out cards and bespoke colour presentation tools any printed material where the colour must accurately represent a physical product
- Accuracy is measured in Delta E against spectrophotometer readings of the actual paint, not against a digital file or a Pantone swatch
- Production requires custom ICC profiles built for the specific substrate, ink system and printing conditions standard commercial profiles are not precise enough
- Substrate selection directly affects colour appearance and must be considered as part of the colour matching specification, not as a separate procurement decision
- Batch consistency across production runs is essential a replacement fan deck printed two years after the original must match it within the agreed tolerance
- The entire sampling supply chain (printing, finishing, warehousing, replenishment) must be managed as a single integrated service to maintain quality control from production through to delivery
What Colour Sampling Includes
Colour sampling is the production of printed materials where the primary purpose of the colour is to represent another product accurately enough for customers to make purchasing decisions. This is fundamentally different from standard commercial print, where colour needs to be “good enough” vibrant, clean and on-brand but does not need to precisely replicate a specific physical reference.

The most common sampling formats include fan decks (swatches bound on a rivet for browsing in sequence), loose swatch cards (individual colour cards for customer take-away), peel-and-stick colour chips (adhesive-backed samples that customers apply directly to their wall for in-situ assessment), colour charts (printed sheets showing multiple colours in a systematic arrangement), and paint-out cards (cards with a painted area alongside a printed colour reference, showing both the actual paint and the printed representation).
Each format has different production requirements, but they all share the same underlying colour management process: spectrophotometer measurement of the reference, custom ICC profiling, controlled production printing, and per-colour quality verification.
How Colour Sampling Differs from Standard Print
Standard commercial print targets colour consistency within a run and approximate fidelity to the supplied artwork file. The reference is a digital file, and the acceptance criterion is visual assessment against a contract proof or a brand colour guide. A Delta E of 3-5 between the proof and the production run is considered acceptable for most commercial work.
Colour sampling targets colour accuracy against a physical reference the actual paint, coating or material that the swatch represents. The reference is a spectrophotometer measurement, and the acceptance criterion is a measured Delta E against that spectral data. The tolerance is typically ΔE2000 ≤ 2.0, with premium ranges targeting ΔE2000 ≤ 1.0. This is two to five times tighter than standard commercial tolerance, and achieving it consistently requires a fundamentally different production approach.
The key differences are: custom ICC profiles built for the specific substrate and ink combination (rather than generic profiles), calibration verification before every production run (rather than periodic calibration), per-colour spectrophotometer measurement during production (rather than visual spot-checks), and batch-to-batch consistency management across production runs that may span years (rather than single-run consistency).
The Briefing Process: What We Need from You
A colour sampling brief should include the colour reference (physical painted samples, existing swatches for matching, or spectral measurement data in CxF, MIF or CSV format), the desired substrate (or a description of the desired appearance and finish so we can recommend a substrate), the sampling format (fan deck, loose cards, colour charts, etc.), the quantity, the Delta E tolerance and any specific measurement conditions, the replenishment requirement (is this a one-off run or an ongoing programme with periodic reprints?), and any specific packaging, labelling or branding requirements for the finished product.
If you are new to colour sampling, the brief does not need to cover every technical detail we will work through the specification with you during the project setup. The most important starting point is the physical colour reference. Everything else flows from that.
Substrate Selection for Colour Sampling
The substrate is not a neutral carrier it is an active participant in the colour result. Two identical ink formulations printed on two different papers will produce measurably different colours due to differences in base whiteness, surface texture, optical brightener content, ink absorption characteristics and surface gloss.
For colour sampling, substrate selection must be made in conjunction with the colour matching specification, not independently. We recommend selecting the substrate before beginning the ICC profiling process, as the profile is specific to that substrate. Changing the substrate after profiling means rebuilding the profile and re-proofing the entire colour range.
Common substrate choices for colour sampling include smooth coated art card (200-300gsm) for standard swatch cards and fan decks, textured coated card for ranges intended to simulate a matt paint finish, high-gloss coated card for gloss and metallic paint ranges, and uncoated stock for natural, chalky or limewash paint ranges where a textured, absorbent appearance is appropriate.
For more detail on how substrate properties affect colour accuracy, see our guide on paint colour matching.
Quality Control and Measurement
Every colour in a sampling production run is measured with a spectrophotometer and compared to the master reference data. The measurement is recorded, and any colour falling outside the agreed tolerance is flagged for adjustment and reprint. This per-colour QC process is significantly more resource-intensive than standard commercial print QC, but it is non-negotiable for colour-critical sampling work.
Measurement conditions are standardised and documented: instrument model, illuminant (typically D50), observer angle (typically 2°), geometry (typically 45°/0°), backing (typically white), and number of averaged readings per measurement. These conditions are maintained consistently across production runs to ensure measurement comparability over time.
We retain the measurement data for every production batch alongside the ICC profiles, calibration records and substrate specifications. This archive enables traceability (any colour query can be traced back to the specific production run and its measurement data) and reprint consistency (future production runs use the same data as the reference point).

Warehousing and Replenishment
Colour sampling products are replenishment items a paint manufacturer’s colour range may remain active for five to ten years, with sampling materials reprinted periodically as stock depletes. Our warehousing and fulfilment service holds finished sampling products in stock and dispatches against orders, with automated replenishment triggers when stock drops below a defined minimum.
Reprint consistency is the critical quality requirement for warehoused sampling products. A fan deck printed in 2028 must match one printed in 2026 because customers and specifiers may be comparing old and new editions. We maintain the complete production data set (ICC profiles, substrate specifications, measurement references, calibration data) for every sampling project and re-verify before each reprint run.
If you have a colour sampling project to discuss, start your sampling project and we will work through the specification, substrates and production approach with you.
Frequently Asked Questions
What is the minimum order for colour sampling?
There is no practical minimum for custom colour matching and ICC profiling we handle ranges from 20 colours to 2,000+. For production printing, minimum order quantities depend on the format: fan decks from 50 units, swatch cards from 100 sets, colour charts from 200 sheets. Prototyping and proof sets are produced as single units for approval before volume production.
How long does the colour matching process take?
Allow one to two weeks for initial colour matching, ICC profiling and proof production. Complex ranges with hundreds of colours may take two to three weeks for the proofing stage. Volume production typically takes one to two weeks after proof approval. Total lead time from brief to delivery is typically four to six weeks.
Can you match colours from a competitor’s fan deck?
Yes. We measure the competitor’s colours with our spectrophotometer to establish master reference data, then match to those measurements. This produces a more accurate reproduction than working from nominal colour values, because it captures the actual printed colour rather than the theoretical target.
What happens if a colour cannot be reproduced within tolerance?
Some colours are inherently difficult in CMYK print very dark shades, highly saturated oranges and certain violets exceed the CMYK gamut. For these colours, we discuss options: extended gamut printing (additional ink channels), tolerance relaxation for specific problematic colours, or alternative substrate selection that may bring the colour within range. We flag these during proofing so there are no surprises at production stage.
Do you provide Pantone references for our sampling colours?
We can identify the closest Pantone match for each colour in your range, but Pantone references are approximations they will not match the printed swatch exactly because Pantone inks and our production inks are different colourant systems. Spectral measurement data is always more accurate than a Pantone reference for colour specification purposes.
Can you produce environmentally friendly sampling materials?
Yes. Options include FSC-certified substrates, soy-based or vegetable-based inks, plastic-free packaging, and carbon-offset production. We can work within specific environmental requirements and provide appropriate certification for the finished product.
