Yes, we will be looking at this very soon as I am planning a 4 color “spot & dot” design in which we will go through the set up and then in a second video we will print the design. I am hoping to get to that soon but in the meantime here are some simple tips for registration.
1) Make sure your screens are rigid and have tight mesh.
2) Also check that there is no distortion in your film output especially with laser vellums or large designs.
3) Use the black printer as the “key” printer to line up all your other screens to. If you do not have a black printer, use the printer that has the most design information on it.
4) You can use the reg marks or cross hairs to generally line up the job but in the end you will have to tweak things with the micro reg looking at the entire design.
5) If you do a push stroke screens lined up to the key printer can be set very slightly above the horizontal cross hairs to compensate for stencil drag. If you do a pull stroke the stencil drag is less and may not require such compensation.
6) Use the least amount of pressure needed to get the coverage desired.
7) Make sure your off contact is set proper. Lower off contact is always better than higher.
8) Be sure your pallets are parallel to the screen during printing.
9) Don’t swing pallets by the pallet or swing screens aggressively when printing. Pallets and printing stations are best moved by using the print arm post as your contact point.
10) If when you set the job up you find one color slightly lower than it should be but lined up otherwise just reverse the stroke.
I hope that helps out a bit. I’ll be working on that new video soon so stay tuned! Thanks so much for using the forum and posting your questions her for everyone to benefit from. Thank you!!
