All my formulas to start will use two colors for ease of use. One set of shirts for Sales, one for Art, and one for Production

I mixed our red and yellow at 4% and no retard...no gelling as of yet with 4 uses. Wish I could lead you in the right direction in regards to the gelling but I'm a newb to discharge at the moment.

Post by: Homer on April 25, 2012, 07:12:30 PM: after talking with Rick, I bet my emulsion has something to do with it gelling. . .I was using DC 521 and I bet it was underexposed, I'm going to try out a few others and see what happens. I know you guys like the 925 rw I believe? I've got a few vendors sending me samples. I'm switching from an SBQ to dual cure. Holy smokes, what a difference. . TP, what is your emulsion of choice for this stuff? that detail is amazing.

Post by: starchild on April 25, 2012, 10:08:01 PM: Now that is my kind of composition.. It's beautiful..
I wish his left side held more details in the highlights however, maybe around 45 lpi on a 230?
If there is detail there though. That is a question not a recommendation.

This site is BA.. Real printers, real experiences, real answers.. I just sit and read everyday..

Post by: tonypep on April 26, 2012, 07:37:10 AM: I am using CCI WR925 and always use a hardener but others mentioned above will work. There is no hard line around the text thats a computer illusion.

Post by: Prosperi-Tees on April 26, 2012, 09:59:34 AM: Tony, what is the proper way to apply the hardener?
Title: Re: One color halftone discharge
Post by: tonypep on April 26, 2012, 10:05:00 AM: Use a wet towel and apply liberally to both sides. Do not dry with a fan that will cause premature evaporation (did I just make a funny?) The hardener will usually tint the color of most emulsions. Dont for get to use emulsion to blockout target marks and any writing/marking on the screen.
