ColorFerm® DeltaE
Multiband spectral capture, ΔE00, statistical filtering and a trainable neural network for more consistent color decisions on the shop floor.
ColorFerm DeltaE is a Spectral Audit System designed to turn color decisions into an objective, repeatable and traceable criterion. It analyzes spectral information in the visible range, processes n inputs from the measurement system and applies a neural network with two hidden layers of 64 neurons to help interpret the result within your company’s real process and its own color library.
It does not simply display data: it turns the measurement into a practical decision for production and quality control.
AI learns from real calibrations and standards to adjust ΔE00 interpretation to real materials, finishes and production conditions. Fewer doubts, more repeatable criteria.
What ColorFerm adds beyond measurement
It does not simply display LAB or ΔE00 values: it combines interpretation, decision support and traceability in a single workflow.
It interprets, not just reports
The result does not stop at figures: ColorFerm turns the measurement into a useful production output through PASS, WARNING or FAIL states.
Learns from the real process
Interpretation improves with calibrations, references and real customer samples, adapting to materials, finishes and use conditions.
Turns use into a company asset
Records, profiles, references and history allow the company to build its own decision base instead of relying only on one person’s experience.
Who it is designed for
ColorFerm DeltaE is aimed at environments where industrial color control must be fast, repeatable and easy to interpret in production.
Quality managers
For teams that need an objective and traceable criterion for acceptance, rejection and tracking color deviations.
Industrial production
For processes where operators need a clear answer on the shop floor without resorting to complex laboratory procedures.
Color-critical processes
Especially useful in paint, plastics, textiles and other applications where small color deviations have a real impact.
Companies seeking to reduce rejections
Designed to help standardize decisions, reduce rework and improve consistency in color quality control.
What is ColorFerm® DeltaE?
It is a Spectral Audit System designed for the shop floor, not only for the laboratory. Its value lies in measuring with criteria, interpreting in context and helping decisions with traceability.
From “it looks right” to measurable data
Each measurement provides CIELAB values and a ΔE00 against the standard or reference defined by the company, allowing decisions on whether a part is within or outside tolerance.
Learning from your standards
The AI model is trained with your standards and accept/reject decisions, gradually refining ΔE00 interpretation for your production reality.
Fast, guided and robust
Quick guides, automatic alerts and simplified workflows so that any operator can use it safely after brief training.
ColorFerm does not impose a standard: it turns each company’s real color library into a measurable criterion
In many industrial processes, the valid color is not necessarily the one from a generic external chart, but the real standard accepted by the customer, by Quality or by the production process itself. ColorFerm DeltaE is designed to work with that reality.
Customer-created references
The company can build its own color library from real production samples: approved parts, internal standards, specific finishes or references accepted by its customers.
Does not depend on a single external standard
The system can compare the measured sample against references created by the company itself, instead of relying only on a theoretical chart that may not exactly represent the real product.
From accepted standard to PASS / WARNING / FAIL
ColorFerm turns samples accepted by Quality into measurable, repeatable and traceable references. In this way, internal visual criteria become part of an objective decision system.
This is a key difference: ColorFerm does not force the process to adapt to an external reference; it helps transform each company’s real standard into an objective control base.
Benefits for your company
One device to reduce subjectivity, speed up decisions and build repeatable criteria through use.
Fewer subjective decisions
Defining and respecting ΔE00 limits reduces out-of-spec outputs and minimizes discussions based only on visual perception.
Faster acceptance or rejection
The combination of measurement, interpretation and visual states speeds up shop-floor decisions without relying on complex tables or later reviews.
More value over time
Every calibration, reference and history record strengthens a knowledge base that improves process consistency.
What problem it solves
It turns a visual, debatable criterion into an objective, repeatable and documentable decision.
Decision variability
Visual inspection creates differences between shifts, operators and lighting conditions. The same part may look correct to one person and not to another.
An objective and repeatable criterion
ColorFerm DeltaE turns visual perception into a data-based decision: CIELAB values, ΔE00 and PASS / WARNING / FAIL states for fast action.
Fewer rejections and rework
By reducing subjectivity, quality-control consistency improves and deviations that end in late corrections are reduced.
Fast decisions without complexity
The system is designed for operators and quality managers who need a clear answer without resorting to complex laboratory procedures.
ColorFerm AI and technology
Visible spectral capture, multivariable processing, guided calibration and a trainable architecture to turn measurement into a practical shop-floor tool.
Multiband capture in the visible range
ColorFerm works with spectral information in the visible range, approximately 415 to 680 nm, and combines that reading with auxiliary variables to build a richer input than a minimal measurement.
Two hidden layers of 64 neurons
The neural network receives n inputs from the measurement system and processes them through two hidden layers of 64 neurons to help interpret color according to the customer’s real references, finishes and standards.
More stability than a minimal calibration
In addition to basic calibration, it can work with intermediate points to improve stability, consistency and sensitivity when the process requires finer control.
It does not only show data: it makes it actionable
The measurement is translated into a useful process output through visual states, tolerances and traceability, bringing the technical result closer to a real operational decision.
Why ColorFerm DeltaE?
A different approach to color control in production: more useful than a solution that only measures and displays values.
Interprets better than a device that only reports
It does not simply deliver LAB or ΔE00 values: it helps interpret the result within the real process context and the tolerances defined by the company.
Learns from the customer’s process
It adjusts to calibrations, references and real samples to bring the measurement closer to the actual behavior of the material and finish.
Easier to implement on the shop floor
It is designed for operators and quality teams, with direct reading and a usage logic that does not force the workflow to behave like a laboratory.
Builds criteria and traceability over time
Profiles, records, references and history turn the device’s use into a company knowledge base.
Designed to deliver a clear industrial advantage
It is not just a meter: it is a decision tool oriented toward production, quality and continuous process improvement.
Measures with criteria
Objective color measurement based on ΔE00 and spectral processing focused on repeatability.
Interprets
The neural network helps turn several technical inputs into a more useful output for the real process.
Decides
The combination of reference, tolerance and assisted interpretation enables faster and more consistent decisions.
Documents
Records and histories provide the documentation base needed for tracking, analysis and traceability.
Industrial applications
A device aimed at processes where color stops being a subjective impression and becomes a measurable criterion.
Paint and coatings
Fast verification of final color, homogeneity control between batches and reduction of rejections due to color deviation.
Plastics and technical parts
Objective visual control over molded parts, colored components and finishes where repeatability is key.
Textiles and treated surfaces
Color tracking on materials with different finishes, supported by the calibration system and adaptive learning.
Production control
Ideal for environments where operators need a fast, clear answer without interpreting complex laboratory tables.
What ColorFerm DeltaE adds compared with a conventional colorimeter
Traditional professional colorimeters are very precise tools for measuring and displaying color values such as LAB or ΔE. ColorFerm DeltaE starts from that base, but is designed to go one step further: turning the measurement into a useful, traceable decision adapted to the real production process.
Interprets and helps decide
A conventional colorimeter delivers technical data. ColorFerm turns that data into a direct shop-floor response through PASS / WARNING / FAILstates, making it easier for the operator to act without interpreting complex tables.
Neural network trained with the customer’s process
ColorFerm incorporates a neural network with two hidden layers of 64 neurons, trainable with real production-process samples: materials, finishes, tolerances and each company’s own standards. This adjusts interpretation to the customer’s real context, internal color library and not only to a generic criterion.
Multiple readings with statistical filtering
Instead of relying on a single reading, ColorFerm can perform several consecutive measurements, compare their repeatability and reduce the effect of anomalous readings on matte, rough, textured or variable surfaces.
Integrated traceability
Each measurement can be recorded with date, time, identified color, LAB values, ΔE, temperature and control result. This turns the device into a tracking tool, not just a point-measurement instrument.
Designed for production
ColorFerm is designed for shop-floor use: simple interface, clear response, visible history, guided calibration and operation adapted to non-specialist operators.
BLE connectivity and mobile app
Bluetooth connectivity allows histories to be viewed and downloaded from a mobile app, making documentation, tracking and device control easier without relying exclusively on a computer.
ColorFerm’s difference lies in integrating measurement, process learning, automatic decision-making and traceability into a compact production-oriented tool.
How it integrates into production
A clear and easy-to-implement flow: reference, tolerance, measurement, decision and record.
Create your own color library
Real samples accepted by the company or customer are measured to create the process’s internal references.
Define acceptance criteria
The ΔE00 limit and warning margin are set according to the reference, finish and the customer’s real requirement.
Measure on the shop floor
The operator measures the part directly in production without complex procedures.
Decide and record
The system displays PASS / WARNING / FAIL and records traceability for the measurement.
How it works in practice
A workflow designed to be realistic on the shop floor: capture, process and interpret with AI support.
1. Capture and calibration
Calibration with real process standards and references. Each adjustment feeds the system’s decision base and improves alignment with specific materials and finishes.
2. Multivariable processing
The measurement combines multiple readings, statistical filtering, visible spectral information and auxiliary inputs before calculating CIELAB, ΔE00 and the interpretation layer.
3. A useful result for decision-making
The system returns objective values and a practical output for production and quality, with tolerances, visual states and a traceable result record.
Intelligent measurement processing
ColorFerm DeltaE is not limited to a single reading. The system applies a processing workflow designed to obtain stable results even on real production surfaces.
Automatic multiple measurements
Each measurement consists of several consecutive readings from the spectral sensor. The system analyzes stability before calculating the final result.
Statistical filtering
Filtering algorithms remove anomalous readings (outliers), increasing measurement repeatability on matte, rough or slightly variable surfaces.
Spectral normalization
Sensor spectral values are normalized before feeding the calculation model, reducing the influence of lighting or reflectance variations.
Trainable neural network
The final color calculation is performed by a neural network that learns from the user’s real calibrations.
Automatic PASS / FAIL decision
The system compares the obtained ΔE00 with the limits defined by the production process and automatically shows whether the part meets tolerance.
Tolerances by finish type
Different tolerances can be defined for matte, glossy or rough finishes, adapting quality control to the product’s reality.
Measurement traceability
The system does not only measure: it also documents the process to support tracking, analysis and continuous improvement.
Result recording
Each measurement can be recorded for later analysis, quality review and historical tracking of color deviations.
Calibration history
System calibrations and adjustments form part of a useful knowledge base for maintaining consistency in the industrial color-control process.
Process tracking
Traceability helps identify trends, detect unwanted color changes and act before they become rejection or return issues.
Ready for analysis
Data can be used to assess stability, compare batches and reinforce color quality control over time.
