First try problems
Posted: Wed May 07, 2014 2:12 pm
Hello All,
I design and manufacture effect pedals Similar to guitar effect pedals) for harmonica players. Well long story short the supplier of my enclosures has discontinued their screen printing services so I have decided to do my own screening. I am screening on powder coated aluminum enclosures and gave it my first attempt today but had a problem. I am using acrylic water based ink to learn with but I play to switching to a solvent based ink as soon as I am confident.
Here is the result of our efforts today.
As you can see there are spots where there is no ink, we started with the ink very thick and thinned the ink on subsequent tries but we had the same problem each time. We tried varying the amount of pressure and the angle of the squeegee (80 dur). One thing to note is that the screen seemed to stick to the substrate and not release, we tried different offsets but there was not improvement.
Any ideas?
Thanks
Randy
