What a Vendor Color Test Taught Me About Hidden Risk in a Sourcing Transition
As part of my work with Alleon Group, I spend a lot of time helping organizations navigate sourcing transitions, supplier changes, and operational process redesigns – particularly in environments where production consistency and speed matter.
During a recent QSR (Quick Service Restaurant) sourcing transition, we went into color testing expecting it to be one of the final checkpoints before moving volume from the incumbent to a new vendor.
The assumption was simple: the artwork is the same, the specs are the same – validate the samples and move forward, but that assumption didn’t hold.
What the color test actually revealed had very little to do with color alone – and a lot to do with how much of the existing production process lived inside the incumbent vendor, not on paper.
Why Transitions Expose More Than Steady-State Production
In a steady-state environment, an incumbent vendor often absorbs inconsistencies over time:
- They’ve learned how files behave
- They’ve adjusted to material quirks
- They’ve built informal guardrails around production
None of that transfers automatically in a transition. So, when a new vendor steps in, they aren’t just replicating output – they’re rebuilding the process from whatever has been documented (and whatever hasn’t).
That gap showed up immediately in testing.
"Press calibration, substrate differences, and proofing standards vary significantly between vendors — what looks consistent on screen can behave very differently in production."
What We Saw When Samples Came Back
On screen, everything looked aligned. In production, the differences were clear.
- Depth varied across menu boards
- Lighter elements lost contrast on certain materials
- Small text began to bleed in some samples
- Background textures showed unexpected graininess
This isn’t unusual. According to industry research, differences between digital proofs and physical output are one of the most common challenges in print production, especially when transitioning between vendors using different presses, materials, and calibration standards.
But what mattered here wasn’t just the variation, it was what caused it.
What The Color Test Actually Uncovered
Once we stepped back, the inconsistencies pointed to something deeper:
The incumbent hadn’t just been producing — they had been compensating for gaps in the process. When those gaps weren’t explicitly defined, the new vendor had to interpret them, and that’s where variability crept in.
Where Transitions Tend To Break Down (And What We Saw Firsthand)
Once we stepped back and looked at the transition more structurally, a pattern emerged – the incumbent had been operating with a level of detail that never made it into the handoff. None of these issues were new, they were just hidden, but this transition forced them into the open.
Area | What the Incumbent Had (Implicit) | What the New Vendor Received (Explicit) | Risk During Transition |
Material Standards | Known substrates, finishes, and tolerances over time | General specs without nuance | Color, depth, and durability vary by material |
Color Targets | Tribal knowledge of “what looks right” | No defined benchmark (Pantone / physical reference) | Vendors optimize toward different visual outcomes |
Proofing Process | Informal adjustments before final output | Digital proofs treated as final approval | Issues only surface after samples are produced |
Review Structure | Familiar stakeholders aligned through repetition | Multiple reviewers without shared criteria | Slower decisions and inconsistent feedback |
Production Assumptions | Learned behaviors built into execution | Assumptions left to vendor interpretation | Increased variability across locations and runs |
This Isn’t Just A Print Problem - It’s A Process Clarity Problem
It would’ve been easy to frame this as a vendor capability gap. It wasn’t.
Research highlights that many production errors stem from breakdowns in workflow alignment and unclear approval processes, not purely technical execution.
That’s exactly what this reflected.
- The incumbent had filled in the gaps over time
- The new vendor followed what was defined
- Internal teams assumed consistency would carry over
Without fully documented standards, consistency was never guaranteed.
What We Changed Before Moving Forward
The value of the color test wasn’t just identifying differences; it gave us a window to fix the process before scaling production.
We focused on tightening a few areas:
- Defined material specifications by use case (not just general categories)
- Established clear color benchmarks and tolerance ranges
- Required physical proof validation before final approval
- Introduced structured review criteria across stakeholders
- Aligned vendors on expectations upfront – not through iteration
None of this changed the artwork, it clarified how the artwork should be produced.
The Takeaway For Any Sourcing Transition
Color testing in a transition environment is not just a quality check. It’s one of the clearest indicators of how portable your production process actually is.
If the process relies on:
- institutional knowledge
- vendor-specific adjustments
- or loosely defined expectations
those gaps will surface the moment a new vendor steps in.
"The hidden cost of a vendor transition isn't the switch itself. It's the undocumented process knowledge that doesn't transfer with it."
Bottom line
If color testing becomes inconsistent or overly iterative during a vendor transition…it’s rarely about color alone.
It’s a signal that the process was never fully externalized from the incumbent in the first place.
And catching that before production scales is what prevents a much more expensive problem later – when inconsistencies show up across hundreds of locations instead of a handful of test samples.
