Opportunity is missed by most people because it is dressed in overalls and looks like work. - Thomas Edison
I have an employee that struggled for more than a few years trying to get the "dead on" print with a tri-loc set up. She was never successful...until she truly watched me set a few jobs up...then the light went on...she was pulling really hard on the frame to pull it into the stop blocks on the jig. So much so that she was able to move the jig. When she started using a soft touch on the set up she too was able to get the jobs locked in and printed without micro on most jobs.We use just enough pressure to make contact on the three blocks and nothing more.Best of luck.
We throw both switches at the same time. The clamps do make a difference. It also makes a difference how the person locking the screen in is holding it against the stops. A few weeks ago my guys were bitching that there was something wrong with it. I went out and set up 4 3 screen jobs and only touched the micros on 1 screen out of all 4 jobs. Its safe to say its not the Trilock that is the problem.
