White Ink opacity issues

<< < (2/5) > >>

balloonguy:
I print a good amount of these. I use house blend of 40% clear and 60% smooth white through 156 on the base (double stroke) then top white is all smooth white through a 156, 135 or 110 depending on art. I find the based down base coat makes it easier for me to get a nice smooth base with less pressure. The top coat sits nicely on top of the thin base.

Atownsend:
I haven't used the ELT before... but i'd question the ink if all other variables check out. With thin thread and a top white that should be bright unless its bleeding fo some weird reason. Did dryer settings recently change? New batch of ink?

Also... unless it has halftones i'd ditch the 150/48 thin thread and rock 135/55 for the base screen. Slightly thicker thread but with better open area since there are fewer and can take higher tensions and more abuse 150's are fragile for us... Joe Clarke (RIP) turned me on to that years ago and its been game on ever since. Clears white ink so easy with light pressure.

The open area is the same. Both have an open area of 51% but the ink volume of the 135-54 mesh is higher. Tension level is not significantly higher either. But I shall give it a try.

mk162:
We'll try some 135s.  I am not a fan of that since I prefer a thin ink film.

We've gone back through anything that could have changed, and came up with nothing.

whitewater:
It could be the chemistry of the ink changed and none of us know... and here people are chasing the way they do things to see if its them..

Im just throwing that out there...LOL
