“When your standard deviation over six months is less than a 0.8 Delta E, it’s because of good people, good culture, and a solid process.” We sit down with DJ Cabler of WestRock, to talk about how they use data to streamline their color management. 

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.
