The nice thing with the Wilflex software is that you can print out a label that shows the PMS number (Nice and big with latest software) and the formula. Slap in ton the container and tape over it with clear tape. No questions on what's in the container, or how to reproduce it. We have over 800 mixes on our shelves. We have sections for 100s, 200s, 300s, etc. We break down further by the ending number being odd or even (still a challenge for many
) So we have a section for 100 Even and one for 100 Odd. More than most need to deal with, but that's our "System"
