Title: White Ink - Do you always flash it?
Post by: cattees on May 30, 2012, 08:19:35 AM

Whenever we have a job with white ink, we always use low mesh and flash (P-F-P), however some shirt colors are pretty light and don't seem to need the flash.  We have a job coming up with carolina blue shirts and white ink.  I'm thinking of just using a low mesh (say 83 or 86) and skipping the flash.  There's much of a difference whether you do or don't.  Just wondering about everyone else - do you always flash with white ink or does it depend on the shirt color??  thanks....

absolutly...there is no need to PFP a lot of colors out there.

not only that, but with an 86, and virtually any EOM, it could well cover on a black shirt! That's probably significantly coarser than you would need for that.

I'd go down to whatever mesh count it took to not have to flash, down to an 83, and if that didn't cover the shirt color with one stroke then I'd go up to a mesh count where PFP would get it done.  Might be a 110, 140 or 156, it all depends.

if i have to print white on light color garments usually i would use a 110 or 120 mesh
now if there dark color plate i would print it first then the white plate last
same thing applies to cool greys or any other ink with a high concentration of white

125 mesh at the end of the print.

Emulsion Over Mesh = EOM  and I do the same thing on light color shirts except I print thru a 110 or 137 mesh and stroke it twice for nice smooth print.

Oooh, ok.  Thats what we do, we coat our screens with Saati PV Textile Liquid Emulsion.  Guess I just wasn't familiar with the technical term.  Thanks....

It isn't a technical term for Emulsion it's a technical term for HOW MUCH emulsion.

It's usually expressed in a percentage... like 10% or 18%.

I'd like to hear someone explain exactly what the percentage represents.
