Looks great Mike.  Glad it worked out.  Sometimes we psyche ourselves out and just need to print.  Remember it is just ink on underwear.

Did you get a peak at the gray screen as far as the white buildup?  I've never had much luck printing directly on a wet white but glad it worked for y'all.  Any reason why you printed the white in front of the gray and not the other way around?  Just asking cause I would have gone gray first, the the UB white.  Just goes to show there is more than one way to murder a cat :)

I will look for the sample we were printing tomorrow where I did try the grey then step on it with the white, the grey looked nasty after being stepped on and did not have the opacity I wanted. It's a much thinner ink no where near as opaque as the white ink.

Gotta ask, why not underbase the grey with the white and print it after the flash? 6/8 press?

After seeing the art I was wondering the same thing.

Why? Well obviously the print came out fine the way I did it. But the obvious answer is the grey would not have been flashed and been stepped on or the yellows would have had more stepped on them. Wanted to splash at least two colors before going to the yellows and red.

good that it came out great but I wouldn't want to print it like that either, what white ink did you use for it?

I get to do 5 screens WOW directly after the flash quite a bit, can be fun at times

The fashion soft/softee etc has a different resin than the rest of the "extenders"  this is what gives it a softer feel.  Has very few additives.  Not all "super soft hand" bases are created equal. 

Curable reducer is typically a standard resin and pasticiser mixed together with a thickening agent to achieve a specific viscosity.  Curable as is (as we all know) does not do much to flash times in small quantities.  May or may not be wet on wet ready... that depends on the resin itself.

If an ink will build up normally, adding anything to it to help it print wet on wet will only delay the need to scrape the back of your screens.  This depends on variable like mesh, squeegee, area of coverage, white plate/no white plate, etc..

If an ink builds up it's because of the solids in the mix... not the liquids.  Not all particle sizes are the same... and some are just downright sticky regardless.

That's it for now... gotta run to work.

I have more answers on ink technology if you have questions.
