Proofreading

What is your method of proofreading a score?
I found an interesting article online:

It would be interesting to hear from some pro engravers how their workflow is. I found that proofreading from the computer screen just doesn’t cut it, much more reliable from paper for me.

Happy new year to all of you!

Mine is still paper and a red pen. If travelling then pdf on ipad with apple pencil. Either way I fix mistakes afterwards and not whilst proofreading.
