    Default Cameo 30/Semi-Auto Question

    Hey everyone,
    Long time lurker, first time posting.

    I've been running a Cameo 30 for awhile now and most runs go smoothly but I've been having trouble with full bleeds. When I try and print full bleeds (18x24" on a 36x48" OD screen) I'm getting what appears to be clogging (always in the corners). I don't believe it's due to my exposure times or washout method as I'm getting high detail burns whenever I use my manual press.

    I also try and remedy this by increasing floodbar and squeegee pressure but I feel like I'm putting too much pressure on the screen.

    Any insight would be helpful as I'm pretty new at the whole semi-auto game.

    Thanks!

    You'll know when it's too much squeegee pressure when the leading edge looks bleedy. I wouldn't worry about too much flood pressure.
    If your registration tabs are thicker than your substrate make sure your not running over them with your squeegee. If your masking out your vacuum make sure your mask isn't thicker than your substrate. Double check that your squeegee is not bowed. Reduce your off contact... raise your off contact (either might help). Adjust your peel. Print on a bigger paper with bigger borders (you'll get better suction this way). Reduce your print speeds. Use a softer squeegee.

    If all is running perfectly and you are just a slow printer then it's natural for the corners to clog before the rest of the image does. Maybe they might clog every 15-30 sheets depending on the humidity and pigment load of the ink.Prewet your screen before adding ink making sure that all of the emulsion is damp. Watch the corners and when they start to clog wet the screen and add fresh ink. Print off the wet stuff on proofing paper and continue printing on the good stuff.

    +1 for checking height of tabs/mask. I always forget that shit when we print on thin Kraft paper.

    Thanks for the replies!
    Never thought it could the tabs. I'll try out thinner tabs and grab a new squeegee.

    Update:

    I replaced my squeegee with a brand new 70/90 and adjusted the squeegee/floodbar pressure to what I usually print at. Got this beauty of a rip. This is a relatively new screen and there weren't any pre-existing holes. It seems like its due to the masking tape on the underside of the screen? Can anyone confirm its this or could it be something else causing the rip?

    did you round out the corners of the new squeegee?

    could just be a random pop too.

    Check your floodbar for dings. If it's aluminum it's especially prone to getting dings and ripping screens.
    What kind of tape was it?

    I usually get ripped if it's really good pot.
