hking19421,
Regarding you technique improvement that you describe as: "...seems to print in almost a gray scale allowing the printed pattern to dry in about 30 min to an hour."
You didn't reveal the "time for ink to dry" aspect of your technique before this. I am amazed that you see "the only problem... is... drill saw dust gets under the film."
I suspect that we all have more time than we have money, BUT, to be happy with a technique improvement that still needs 30-60 minutes for ink to dry is NOT an efficient method at all.
Print the pattern on paper, for gosh sakes... nothing is cheaper or quicker... and it's less prone to smearing compared to printing on plastic.
Then, either:
a) lay down (on the workpiece) a layer of packing or masking tape or a cheap self-adhesive shelf paper and attach the pattern atop that with spray adhesive, or
b)attach the pattern to the workpiece with spray adhesive and cover that with clear packing tape or transparent self-adhesive contact/shelf paper.
Either approach would have you ready to begin work less than 5 minutes after the printer is done. And I suspect the costs are at most equal to and potentially far less than, what you're doing.
I don't mean to imply you have to do it like I do it... but I implore you to re-examine your method in a better light.
