So im pretty much new to the whole tshirt thing, and i just picked up all of my supplies a couple days ago. One problem that i have ran in to is how long should i expose SPIKE emulsion for when burning my images? For right now, untill i make a exposure unit using UV light im using the sun. About how long should i Expose SPIKE emulsion in the sun for, and how do i know when it is ready to be washed out? I tried 5 mins and then 10mins, basicly i can see the image in the mesh but it wont wash out so i removed the emulsion and im starting back to square one.

Oh one more thing, i got international coatings black plasticol ink, can i dry it with a blow dryer or do i have to heat it up to like 300 degrees like i heard from someone...


Any info, or help is greatly appreciated considering the fact that i have no idea what im doing as far as emulsion exposure time.

Thanks,

Mickey

Do a forum search on exposure times.

SPIKE is designed to optimize at the 420 nanometer spectral point, so make sure your exposure unit takes advantage of that very specific characteristic.
