Haze appears due to two reasons:
1: The pigment in the ink or emulsion causes the haze
2: The uncured emulsion once comes in contact with some harsh press wash or ink Degradent, leaves a permanent coalesced film.
The 2nd.type of haze can not be eliminated.
The 1st.type of haze may be removed by using an inkgradent. If that does not work than you may use haze removers available in the market place.

The sequence of procedure described is correct. There are inkdegradents that are ink & emulsion remover and act as degreaser. The coalesced film can not be completely eliminated by a strong caustic solution, combined with surfactants and solvents. The imbedded portion of the coalesced film in the screen is such that if you let caustic solution stand for too long, it attacks the filament in the mesh. The other problem is the time consumed and exposure to harsh chemicals is not worth it. You are better off to re-mesh the screen for $7.00.

I never really have bad haze problems with my t-shirt screens or plastisol. Now my big screens are a different story and they are more like 60-80 bucks a piece to stretch new fabric in. Corogloss can leave some rsidue and god forbid you don't properly clean a screen after printing metal all day with catalyzed ink. I use GB 2000 ink stain and haze remover from Nazdar. Works pretty well.

Does a haze of an image cause problems with a new stencil?
I have some screens with ink images left from watercolor ink as well as plastisol. It didn't really seem to matter until I tried to burn a high resolution image onto it. Is that why image haze is unwanted?
Thanks!
