Roadmap for Implementing Color Matching Quality Control for Indigo Presses

Goal: Establish a comprehensive color-matching quality control system for Indigo Presses utilizing Print Inspector for process control and ChromaChecker Capture for spot color matching.

Assumptions:

• Indigo Presses are stable and consistent as reported in Print Inspector.
• Necessary hardware (ChromaChecker Capture with spot instrument) is available.
• Access to press serial numbers and API keys/secrets for authentication.

Prep Items:

• Gather Press Information:
  • Collect press serial numbers for all relevant Indigo Presses.
  • Obtain API keys and authentication secrets with Print Inspector and ChromaChecker Capture.
• Software Installation & Setup:
  • Install ChromaChecker Capture software on the designated workstation.
  • Calibrate and profile the spot instrument used with ChromaChecker Capture according to manufacturer instructions.

Implementation Items:

• Instrument Baselining:

  • Perform an initial baselining of the spot instrument in ChromaChecker Capture.
  • Establish a regular monthly re-baseline schedule to ensure the instrument's consistency.

• Process Color Conformance:

  • Determine Reference Aim: Define the target color appearance (e.g., industry standards, brand guidelines).
  • Determine Substrate: Identify and document all substrates used in production.
  • Determine Tolerance: Establish acceptable color deviation limits for each substrate and application.
  • Determine Control Strip: Design and implement a standardized control strip for each substrate, including process color patches.
  • Determine Measurement Workflow:
    • Define the process for measuring color on the control strip (e.g., using a densitometer, or spectrophotometer).
    • Implement a standardized data collection and analysis method.

• Spot Color Conformance:

  • Determine Reference Colors:
    • Define and create a comprehensive Master Color Library within ChromaChecker Capture.
    • Include all standard spot colors used by the press.
    • Measure and record the spectral data of each color using the spot instrument.
    • Consider creating libraries for both spot and simulated spot colors.
  • Determine Substrate: Identify and document all substrates used for spot color printing.
  • Determine Tolerance: Establish acceptable color deviation limits for each spot color on each substrate.
  • Determine Measurement: Define whether to measure single colors or a control strip containing spot and/or process colors.
    • Determine the appropriate measurement workflow (e.g., using ChromaChecker Capture, spectrophotometer).

Color Matching & Production

• Process Color Conformance:

  • Roll Out to Suppliers: Communicate color standards and measurement protocols to all relevant suppliers.
  • Check Connectivity: Ensure seamless data exchange and communication between all stakeholders (printers, designers, suppliers).
  • Establish Reporting Guidelines: Define clear reporting guidelines, including timing, frequency, and the scope of data to be collected and analyzed.

• Spot Color Conformance:

  • Roll Out Color Library to Designers:
    • Provide designers with the Master Color Library in a usable format (e.g., Pantone Color Books, digital swatch libraries).
    • Train designers on how to use the library and export named colors correctly.
  • Roll Out to Suppliers:
    • Provide suppliers with the Master Color Library and instructions on how to use Color Match Scan (or similar tools) to build Spot Color Look-Up Tables.
    • Implement a system to verify that suppliers are matching spot colors to brand tolerances.
  • Deploy Projects: Integrate color management protocols into all production projects.
  • Check Connectivity: Ensure seamless data exchange and communication between the PSP (Print Service Provider) and the brand.
  • Establish Reporting Guidelines: Define clear reporting guidelines, including timing, frequency, and the scope of data to be collected and analyzed.

Monitoring & Maintenance:

• Regularly monitor press performance and color consistency using Print Inspector and associated Dashboards.
• Define periodic color checks using ChromaChecker Capture to verify color accuracy and identify any deviations.
• Establish a regular schedule for visual inspections of printed output by a qualified color expert.
• Update color libraries, and refine LUTs to maintain optimal color quality.
• Implement a system for tracking and documenting all color-related adjustments and their impact on print quality.
• Continuously review and refine the color management system based on data analysis and feedback.

Benefits:

• Improved color accuracy and consistency across all Indigo Presses.
• Reduced waste and rework due to color discrepancies.
• Enhanced customer satisfaction through improved print quality.
• Increased efficiency and productivity in the print production process.
• Data-driven approach to color management enables proactive adjustments and continuous improvement.
• Reduced environmental impact due to decreased waste from color errors.
