Closed Loop System

A "Closed Loop System" refers to an automated control mechanism that continually monitors and adjusts various parameters within the printing process to maintain consistency, accuracy, and quality. It involves sensors, feedback mechanisms, and control systems that work together to ensure precise printing performance.


Automated Printing Control System


  1. Color Management Systems (CMS): Closed loop systems in printing often include CMS that utilize sensors to measure color density and spectrophotometers to provide feedback on color accuracy. The system automatically adjusts ink levels to maintain consistent color output throughout the print run.
  2. Registration Control: In offset printing, closed loop systems are used for registration control. Sensors detect any misalignment in the printing process, and the system automatically makes adjustments to ensure precise alignment of colors and elements on the printed material.
  3. Art Reproduction and Fine Printing: Artists and galleries often employ CMY-based printing methods for reproducing high-quality art prints and fine art pieces. The CMY color model allows for accurate reproduction of original artwork's colors and tones.
  4. Newspaper and Magazine Printing: While some publications have transitioned to digital formats, many newspapers and magazines still utilize CMY-based printing processes. This color model enables cost-effective reproduction of images and graphics within publications.


For the effective implementation and optimization of closed loop systems in the printing industry, consider the following recommendations:

Invest in Quality Sensors and Technology: Utilize high-quality sensors and advanced technology to ensure accurate data collection and feedback within the closed loop system.

Calibration and Maintenance: Regularly calibrate and maintain the sensors and control systems to ensure their accuracy and reliability in monitoring and adjusting printing parameters.

Training and Expertise: Provide training to printing personnel to understand and manage closed loop systems effectively. Expertise in interpreting feedback data is crucial for optimal system performance.

Integration with Workflow: Integrate closed loop systems seamlessly into the printing workflow to ensure efficiency and reduce downtime.

Continuous Monitoring and Improvement: Continuously monitor the performance of the closed loop systems and make necessary adjustments or improvements to enhance print quality and consistency.
