Just recently i have noticed a shiny reside left in the printing area of the screen after i wash it out (after burning before printing shirt) It looks open until it dries which I do standing them up with a fan blowing on them. I always have to wash it twice. I have not changed chemicals and i use a power washer. Anyone have any idea?
Ok, if I understand correctly, you're not noticing any image haze until after you've exposed your screen and before you load it with ink.
Hmmm, it could be that your screen is not fully dried before you're exposing it and you're getting some slime effect. What could be happening, if that's the case, is that yeah you're clearing your image (that you've exposed) but then you're getting some slimy emulsion running down into your image. Like the previous post mentioned, after you rinse your screen, lay the screen flat onto a few layers of newspapers (on the shirt side), then quickly lay a piece of newspaper on the ink side, lightly tamping it down with a crumpled up piece of newspaper....then remove ASAP. I would not rub directly onto your exposed image without the paper buffer. You want to remove the newspapers right away so they won't bond with the emulsion.
But, like I said, it does sound like your emulsion might not be fully dried before exposing. If it feels slimy when wet, it's not dried fully.
