Phase 10 of the “Color Rules” covers the common question: How often does the camera read the color bar? The video goes in-depth into managing ink zones on the KBA press and breaks down the process step by step, explaining how ink settles zone by zone and how adjustments are made accordingly.

Key highlights:

    • Frequency of Camera Readings: The camera reads every color bar.
    • Ink Settlement: The system takes an average of every 8 sheets and then makes the adjustment, zone by zone.
    • Dynamic Adjustments: With Dynamic control, the system will increase or decrease the ink key opening more than target or less than target to get to the proper density in the quickest way possible. We can only do this because we are seeing the density on every sheet.  With Dynamic Control, density is adjusted in the fastest way possible. 
    • Speed of Adjustments: The process is quick. It is impossible to get to color faster using manual control.

Color Rules relies on the adherence to four main phases. Each phase of the process requires a documented procedure that must be followed closely to achieve true success. 

Do you have an inline closed-loop color control device that scans every sheet? For the fourth and final step in the process, drive the press to target density. Get there as quickly as possible and maintain density throughout the run.

  • Test and update your ink key presetting curves on a regular basis
  • Use only inks that meet GRACoL specifications
  • Tweak your densities based on neutral grey
  • Run every color to recommended LAB/Best Match density with the lowest Delta E possible

By installing LithoFlash and following the outlined Color Rules process, you will reduce waste, improve performance, and save time and money.
