I print the coro signs on B-line cheap vinyl from Nglantz, then I use a big Squeegee to lay them down, B-line lays down perfect on a coro blank, I did 100 3 weeks ago & didn't mess any up. I would have struggled with that many 3651 prints. Made some cash on that job. They wanted them quick.
Here is how you use the BS
The material is 30" wide
The print is 24, (I weed it first, this is when I like having a print cut) weeds in seconds
Then I trim the bottom slicing just a fraction of the print, this gives me a straight line to work with
Then I trim both sides of the bottom print up about 3 inches on both sides (freehand cut with knife)
I use 2 clothes pins to hold the print while I tape it
I hit the tape on my pants leg so it doesn't stick as much (do it best painters grade is my favorite)
I tape it down with 2 inch masking, folding it over, pay attention to the bottom edge with the tape first then wrap around the back, trim the edges.
I flip it back, peel it & lay it down in like 3 seconds
done
peel the tape -on to the next one
I have a square long 1 x 1 I clamp on the table to jam against while I squeegee
Might seem like a lot of work but I do these so fast I don't even think about it now.
Good luck, I never lam a coor print by the way
T trim the bleed signs, I use a smaller breakaway razor knife & stick the blade out really far then trim like that.
