Using an inkjet printer to make precreasing of CPs easier

Here is a trick I’ve used a number of times when test-folding my own crease patterns. If you find the pre-crease time-consuming, you can print out the CP on an inkjet printer. Ink will soften the paper and even after it dries out, you will be easily able to crease exactly along the printed lines.

This method does have the disadvantage of the printed lines smearing a little and making your hands dirty, so I wouldn’t recommend it for clean folds, but for test folds, I think it’s an acceptable trade-off and saves a lot of time.
