So I picked up this American Tempo cheap a couple months ago, I know nothing about running a semi-auto as I have always done everything by hand with homemade vacuum table setup. So I had to do a bunch of wiring to get it running well again and got the pressure settings perfect on the squeegelizer, off-contact, etc. I was thinking this is going to be great having a micro registration table but then I go to print and I'm puzzled...obviously for the first layer you lay down marks on a a test print (registration print, whatever you want to call it) and line it up as close as possible...now here is what got me, when I line it up on my hand table I turn on the vacuum before I lift the screen so it doesn't move and I can tape down my bumper registration card stock. On the semi-auto the vacuum is running all the time but only engages the suction when it is in a print cycle and not a flood stroke. So I can line it up perfectly on the next layers when the head is down and the vacuum is on, but the dilemma is you have to lift the head back up to tape down bumper card stock and the vacuum turns off, so how the hell do I know if my paper just moved when the head lifted? Really there should be a switch to turn on the vacuum when the head is up (obviously this is not possible on my machine I opened it up and the vacuum is in a box with a port that slides open and closes with the action of the head going up and down). Anybody got a good suggestion. All I can think is line it up as close as possible, tape down your registration print, then micro it, and tape down your bumper stock.
