In the printing and packaging world, color is more than aesthetic—it's a promise. When a brand sends its artwork to press, it expects the final output to match its visual identity precisely. The ability to deliver on this expectation—across different substrates, devices, and locations—relies on a robust color management system.
At the heart of effective color management lies a set of foundational principles often referred to as the “C’s of Color Management.” These C’s—Consistency, Calibration, Characterization, Conversion, Control, and Conformance—represent the framework for achieving color accuracy and predictability.
Companies like Colortech have harnessed these principles to create a competitive advantage. In a recent feature from Printing Impressions, Colortech’s investment in color control technology helped reduce waste, improve print-to-proof match, and elevate its reputation among brand clients. Their success story underscores a vital industry truth: managing color well is not just a technical achievement—it’s a strategic business move.

We’ll explore each “C” in greater depth in this article to understand how they work together and form the backbone of professional color management.
1. Consistency: Establishing a Stable Foundation
Color accuracy starts with consistency. Before a printer can reproduce colors reliably, all equipment must operate in a known and repeatable state. That means:
- Press or device is operating properly. (E.g. Printheads are clean and aligned, or plates and anilox are clean and ready for use.)
- Substrates and inks are consistent from batch to batch, and optimized for use.
- Environmental conditions (like humidity and lighting) are controlled.
Without consistency, even the best color profiles or calibration methods will fall short. This is why color management begins before a single-color patch is printed. For Colortech, consistency came from standardized processes and automated maintenance routines, ensuring every shift began with devices in their optimal state.
2. Calibration: Aligning Devices to Known Targets
Calibration ensures that each device—whether it’s a printer, monitor, or proofer—produces a predictable response. It involves adjusting settings such as:
- Tone reproduction curves
- Ink limits
- Linearization of CMYK or multi-channel outputs
- Gray balance (G7®)
Calibration isn’t a one-time task—it must be maintained over time. Many advanced print systems include built-in calibration tools or work with digital front ends (DFEs), which simplify this process through guided workflows. By regularly calibrating their equipment, Colortech eliminated variation between devices and shifts, building the trust necessary to serve demanding brand clients.
3. Characterization: Creating Accurate Device Profiles
Once devices are consistent and calibrated, the next step is characterization—the process of building an ICC profile that defines how a device interprets and reproduces color. This involves:
- Printing a color target (e.g., IT8.7/5)
- Measuring the patches with a spectrophotometer
- Creating a profile that maps device behavior in LAB or PCS color space
Each combination of printer, ink, and substrate requires its own profile. A coated sheet with offset ink won’t behave like a textile or uncoated flexo substrate. At Colortech, extensive profiling across devices ensured they could move jobs between presses or locations without compromising visual quality.
4. Conversion: Translating Color Across Devices and Spaces
Color conversion bridges the gap between devices, ensuring that an RGB image designed on a screen can be accurately printed in CMYK—or that a brand red looks the same on a carton, label, and banner.
Key components of color conversion include:
- ICC-based color management workflows
- Rendering intents (Perceptual, Relative Colorimetric, etc.)
- Use of device link profiles or color management modules (CMMs)
Without proper conversion, even the most accurate profiles won’t yield predictable results. For example, if a bright green in a logo exceeds the CMYK gamut, the conversion algorithm must smartly approximate it.
Modern DFEs and RIPs handle this in real time, allowing print service providers to optimize each job’s appearance while preserving brand integrity.
5. Control: Monitoring Quality and Ensuring Long-Term Accuracy
Control is about verification and monitoring. Even the best color workflows degrade without oversight.
Print providers implement control by:
- Running test charts or control wedges regularly (e.g., Idealliance Control Strip)
- Using quality management tools
- Setting tolerances for Delta E (e.g., average < 2.0, max < 5.0)
In Colortech’s case, integrated quality control solutions enabled them to flag deviations in real time, preventing errors before they reached the customer.
This layer of control transforms color management from a reactive process into a proactive quality assurance system.
6. Conformance: Meeting Industry Standards and Customer Expectations
The final “C” is Conformance—the ability to align with established color standards such as:
• G7® for gray balance and visual appearance
• ISO 12647 for offset color printing
• ISO 15339 for a standardized set of global color spaces
• GRACoL®, PRINTWIDE®, or ECG profiles for specific print conditions
Conformance gives printers a language to communicate color expectations. It also provides confidence to brand owners that their colors will be reproduced accurately.
Certification programs from Idealliance & PRINTING United Alliance, such as G7 Master or System Certification, formalize this capability—offering independent third-party validation that a printer meets rigorous color standards.
Real-World Impact: From Theory to Practice
While the C’s of Color Management may seem abstract, their real-world impact is tangible. Colortech’s story is a prime example. By investing in color automation, profiling, and verification tools, they:
- Improved customer satisfaction with better color match
- Reduced reprints and make-ready waste
- Streamlined onboarding of new jobs and clients
- Elevated their market reputation as a color-capable partner
As Kerry Malony of Fiery noted, “If you don't have professional color management or you don’t use it properly, you’re going to introduce problems. Big problems like waste, lost customers, and a loss of reputation.”
Color Confidence is a Business Strategy
Color management isn’t just a technical discipline—it’s a strategy for reducing risk, increasing efficiency, and delivering value to brand clients.
When printers adopt the six C’s: Consistency, Calibration, Characterization, Conversion, Control, and Conformance, they unlock a new level of operational excellence.
In today’s competitive landscape, accuracy isn’t optional. It's the cost of entry. The ability to measure, manage, and maintain color across an entire production ecosystem is what separates print service providers from true color partners.
And as Colortech’s success shows, those who master the C’s don’t just match color, they win business.
