Mr. Chen, a color management expert at Kaiyin Technology, was invited to deliver a specialized training session on color management for a leading brand.

This brand often faces a common problem: after the proof is approved and the color looks just right, it changes once it reaches the printing plant. With repeated revisions, the delivery timeline gets extended, and costs rise accordingly. The brand wants to know— Where exactly is the problem?

The training revolves around “Digital Proofing Standardization” This core topic is explored. Drawing on the real-world challenges brands face in aligning proofing colors with print results, Mr. Chen, a color management expert at Kaiyin Technology, systematically outlined the rationale behind establishing a standardized color-management workflow.

During the training, Teacher Chen systematically explained the core principles underlying the color alignment between proofing and printing.

The core issue lies in whether standards are unified. Digital proofs that comply with international standards allow printing houses to achieve consistent color reproduction simply by applying the corresponding curves. International standards serve as a universally applicable reference framework, whereas custom standards require each printing house to undergo additional adaptation.

Equipment, paper, and inks vary from one printing house to another, but as long as the brand provides proof prints that meet international standards, the printer can adjust its color curves accordingly—eliminating the need for the brand to adapt to each printer’s specific equipment differences.

During the training, the consultant introduced GMG ProofControl + xRite i1io—a tool used to verify whether digital proofs comply with international standards.

Once proofing is complete, simply place the control strip in GMG ProofControl for measurement. The system will automatically assess the color accuracy of the proof and determine whether it falls within the tolerances specified by the ISO standard or the target proof. When a green checkmark appears on the software interface, it indicates that the proof has passed verification.

Once verification is complete, affix the self-adhesive label to the proof; this proof then becomes a legally binding contract proof. Regardless of which printing house it is sent to, they can use it as the standard for production, eliminating the need for repeated communication and clarification.

The significance of this stage lies in: In the past, there was no objective basis for assessing whether a print shop’s proof met the brand’s standards. Now, with GMG ProofControl, whether a proof complies with international standards is clear at a glance—data does the talking.

During the training, the consultant explained the complete rationale behind standardized color management:

Printer, ink, and paper in one. — Any change in any stage will affect the color. Printers must be calibrated regularly to ensure no clogs and precise ink‑level control; inks should offer a wide color gamut and consistent performance; and paper must be compatible with the ink system to deliver accurate color reproduction and efficient drying.

The operational process can be summarized in a few steps:

Step 1: Calibrate the printer to ensure the device is in proper working condition.

Step two: Print a color chart on standard digital paper, then use a professional scanner to acquire the device’s color gamut data and generate an ICC profile. This profile characterizes the device’s current color reproduction capabilities.

Step 3: Load the international standard curve into the printing software.

Step four: Using the software’s color‑conversion engine, the printer simulates standard printing results within its own color gamut.

After the proof is output, it is verified using GMG ProofControl. Once verification is complete, affix the label; this proof will then be a traceable contract copy and can serve as clear evidence for communication with the printing house.

The core value of this training lies in helping brands understand the significance of standardization in color communication.

Once a brand has digital proofs that meet international standards, the printing house has a clear benchmark to work from. GMG ProofControl enables brands to objectively verify whether their proofs comply with these standards, replacing subjective judgment with data-driven insights.

Brand owners no longer need to accommodate the equipment variations of each printing house; they simply establish a standardized workflow—using digital proofing, validating with GMG ProofControl, and producing proofs that meet international standards—while leaving it to the printers to align with those specifications.

This is not a one-off operation, but rather a reusable, traceable system. Once a brand establishes a standardized color‑management process, it can continuously provide the supply chain with consistent color standards, thereby reducing the need for repeated confirmations and revisions caused by color inconsistencies.
