I'm a new Zing Air owner and, having used an Exacto knife for both cutting and scoring for many years, I was having a hard time believing that I couldn't make viable score lines with the same blade that cuts. I searched these and other forums and found that most people are perforating, and that wasn't going to work for me. (I had ordered an embossing tool, but, really, I wanted to do this with the blade already in the machine for cutting.) I finally came up with a solution which worked for me, and I thought I'd share it. No point in all of us wasting paper on tests, right?
I wanted to score on the first pass and cut on the second, and every
test I ran cut
the paper. On about my 8th attempt, it was clear that cutting was not going to be a problem in the least bit -- every blade height and every setting of force would cut this particular card stock, so if I could get a score to work, it wouldn't take much adjusting to do the cutting.
So I adjusted the blade inside of the blade holder so that the tip barely
stuck out -- less even than the manual says for cutting. (Not that I am suggesting you do this, because these blades are SHARP, but I ran my finger across the point, and it barely scratched it, though I could
feel it.) I marked the blade holder with tape, as in the attached photo, put it in the Zing at the prescribed cutting height, set the Force to 1, and sent my score-line layer to the Zing.
Then I turned the top of the blade holder one full time to the right, matching up the tape again after turning, to push the blade out a bit more, set my force to 65, and sent my cut-line layer to the Zing.
The scores were so perfect the envelope nearly folded itself.
I am doing a large quantity of envelopes, and the point to the tape marking is that I don't have to guess as to how far to turn the blade adjustment when I do the second, third, and so on, score lines.
Hope maybe this keeps someone else from ruining gobs of paper!
