Perfect! Engineers no what they are doing.My first print job, I pick up the arm just to see how the print look and not enough ink, so then I attempt to put the arm down and was not able to put it down on the same exact spot. So had my husband look at it. I just did not put it together correctly as like some of you I followed instructions as what the video gave, so any way made some adjustments. Also took a few of the washers out so my screen can lay well on the platen. So over all I am very happy with this print screen. Everything works perfect, no drilling extra holes. Like I said the engineers who designed this know what they are doing. Although instructions were a little off.Thanks.
