Best Practices for Creasing E-Flute Cardboard and 12/18pt Sheets

I’ve been running a Colex cutter for a while now and frequently work with E-flute cardboard and 12/18pt sheets. One issue I keep running into is cracking—when I crease from the back and then fold, the ink and paper tend to crack.

Right now, I use a 3pt wheel for Tango 12pt and 18pt, and an 8pt wheel for E-flute (just ordered a 6pt to test). But even with these tools, the creases just don’t come out as clean as what box companies produce.

Does anyone have any tricks, settings, or techniques that help minimize cracking and improve crease quality? Any advice would be much appreciated!

Thanks!
