3-2 CORRECT TANGENTIAL KNIFE CALIBRATION TEST
Rectangle 1 and 2 should weed out (remove) smoothly without sticking to the rest of the
vinyl.
The fan shaped pattern 3 should have a clear cut line in the middle; the ones at the sides
show burs.
The squares in 4 should be aligned and equal in size.
The 4 vertical cuts in 5 should be clear without any burs and straight all the way from top to
bottom (not rounded near the horizontal lines).
NOTE: It is possible that not all test patterns come out perfect (depends on the type of
vinyl). Test pattern 1 and 4 are the most important test patterns. They should be as close to
perfect as possible.
