01
One specified standard.
Exactly one reference applies to all processes for a given color. Where design, the mill and the trim supplier each hold their own version, every comparison afterwards is arbitrary, and no tolerance can repair that.

Benefits
What MatchBox makes possible.
01Automated lab-to-standard validation
Every incoming lab dip is colorimetrically validated against the stored spectral standard. dE values under multiple illuminants are calculated, documented and linked to the sample, instead of being tracked manually in spreadsheets.02Configurable tolerances per material / season
Tolerances can be differentiated by material, color family, season or supplier. A heavy wool knit gets different limits than a lightweight blouse, and the rules apply equally to everyone involved.03Approve or reject with justification
Approvals and rejections are recorded with justification, owner and timestamp. This creates a complete audit trail that holds up for claims, compliance questions and internal reviews.04Reduces sampling loops by up to 60%
Because sub-standards are checked digitally against the master and risks surface earlier, the number of physical lab-dip loops drops. Actual reductions depend on the setup, typical projects save a significant share of loops.05Color-managed display: color-accurate rendering on calibrated monitors
Display inside DMIx happens on color-managed, calibrated monitors with ICC profiles and proper color management. What you decide on screen matches the spectral truth of the sample, not the random calibration of an arbitrary laptop.
Definition
What MatchBox is.
MatchBox is the spectral color approval module of DMIx, the Product Reality Management System by ColorDigital GmbH. A brand specifies one color standard as spectral measurement data, defines the tolerance and the allowed direction of deviation for each process, and its suppliers measure and approve lab dips and bulk against that standard on their own instruments. Every approval is logged with the measurement behind it and is visible to the brand in real time.
MatchBox does not replace the judgement of the people who own the color. It makes sure the decision they made arrives at the dye house intact.
Governance
How a brand sets tolerances across its supplier base.
Rolling color measurement out across a supplier network is a governance question before it is a software question. MatchBox structures it in four decisions.
02
A tolerance per process, not per company.
A knit, a print and a coated trim cannot hold the same window. The tolerance is derived from what the finished product has to achieve, which means it is set per material and process rather than copied across the book.
03
A defined direction of deviation.
A tolerance alone tells a dye house how far it may be off. It does not say in which direction the deviation is acceptable, which is the information that turns a correction into one step instead of three.
04
Who may release what.
Trusted suppliers can be permitted to release their own in-tolerance results, while anything outside tolerance stays in the standard review. The permission is per supplier and can be withdrawn.
None of these is a setting a supplier can quietly reinterpret, because every approval carries the measurement data it was granted against.
Feature
Supplier Self Approval
Trusted suppliers approve their own lab dips in MatchBox whenever the measurement falls within the brand's spectral tolerances. The brand stays in control: standards, who is trusted, real-time visibility and full audit trail. What disappears is the waiting, not the verification.

Brand defines target color
The brand sets the binding color standard as the single starting point for every partner in the supply chain.
Today, reality in the supply chain
Why color development does not scale on its own.
Color development was never built to scale.
Classic lab-dip development runs on physical standards, shipping between countries, emails, spreadsheets and private side conversations. With thousands of parallel jobs, every brand loses oversight.
Typical today
- ·Physical color standards and dyed samples
- ·Shipping between brand, supplier and dyehouse
- ·Email threads and spreadsheets
- ·Manual, subjective evaluation
- ·Different tools on every side
Consequence
- ·Long approval cycles, no clear status
- ·Knowledge in individual inboxes, not in the system
- ·Supplier performance hard to measure
- ·High logistics and sampling costs
- ·No transparency across the supply chain
If everyone is meant to see the same color, they need the same data basis.
Color is tricky. Color is a technical process of material, chemistry, light and tolerance.
In industrial processes, a color cannot simply be copied. Material, dyehouse, chemistry, location, lighting and batch variation shape every result. Without a digital system you get diverging interpretations, missing comparability and long review loops.

Deep dive
White is the hardest color to get right.
White is not one color. It needs spectral data, a managed White Point, and a defined tint tolerance enforced at every tier of the supply chain. Otherwise a base fabric, a print, and a trim that all read as 'white' on screen will clash on the finished product.

Standard and tolerances
How the standard and the tolerances work.
One truth
The Standard is the Standard is the Standard.
Once a brand approves a spectral standard, it is the single reference used for lab dip, bulk production, and every reorder, across every supplier and every location. No re-measurement, no re-interpretation, no drift between sites.

Single point of truth
Spectral color data as the shared foundation.
MatchBox works with spectral measurements instead of color names, codes or photos. Suppliers receive a physical color definition that holds independently of device and light source. MatchBox becomes the single point of truth for standards, measurements, tolerances, decisions and approvals.
- 01Objective color communication
- 02Reproducible target values
- 03Fewer interpretation errors
- 04Comparability across suppliers
- 05Global consistency
Tolerances, pass / fail
Configurable per material, season and supplier.
Brands define what deviations are acceptable. MatchBox evaluates every measurement automatically and returns a clear pass or fail, with a complete audit trail.

Directional tolerances
When identical is not possible, harmony has to be.
Across different materials, countries and dyeing technologies, a brand color is rarely identical. Directional tolerances control not just the magnitude of the deviation but also its visual direction, so collections stay harmonious.

Expert to expert
Direct line between brand color team, supplier and dyehouse.
In classic setups a brand comment travels via Tier 1 to the dyehouse, and "more red" can mean anything on the way. MatchBox connects discussion, measurement and colorimetric evaluation at the job itself. Intermediaries stay informed without technical detail being lost in translation.
Scalable job management
Thousands of parallel jobs stay manageable.
Freely configurable filters, tags, status fields and workflows adapt to your organization, not the other way around.

Connections
How MatchBox connects to PLM, 3D and other systems.
MatchBox is never isolated.
MatchBox does not replace a PLM system. PLM holds the specification, MatchBox holds the measured reality behind it, and the two exchange data through AppLink, the API-driven workflow for connecting external applications. Suppliers connect through PaX and the Digital Handshake, so data moves between two companies only where both have agreed to the connection.
Suppliers working with MatchBox will find the dye house view of the same workflow under Lab-Dip & Bulk Approval.

Frequently asked questions.
There is no single answer, but four questions decide the fit. Does the system hold one specified standard as measurement data rather than as a name in a field. Can tolerances be set per process with a defined direction of deviation. Can suppliers reach it without buying a separate licence for every brand they work for. And does it connect to the PLM and 3D systems already in use. A platform that fails the third question rarely reaches past the first supplier tier, whatever its color science looks like.
