Bust the ghosts left in the wake of emulsion under-exposure by Ulano Fast Acting Haze Remover

Most screen printers have seen ghosts. And these ghosts haunt the future print runs. Screen printers are familiar with the haze in the print quality that appears out of nowhere. In truth, if we peel the onion, these ghosts are lying in the stencils. Sometimes under-exposure of emulsions leaves bits of emulsion lodged in the mesh. To a naked eye, these look like stains and one usually uses solvent based ink remover to get rid of them. This is how a ghost is born! Ink remover binds the bits of emulsion to the mesh and there is no way of exorcising your stencil.

But prevention is cure. The unmatched chemistry of Ulano Fast-Acting Haze Remover Gel is the silver bullet that screen printers need to get rid of ghosting on the screen. It is unlike other solvent-based ink removers. Its active ingredients lead to the eviction of most stubborn of under exposed emulsions in the screen.

How to Remove Ghost Haze from the Screen by using Ulano Fast Acting Haze Remover


Remove ink with a good ink solvent. Reclaim the stencil with a commercial stencil remover, such as Ulano’s Stencil Remover No. 4. Rinse thoroughly with water.


Apply Ulano Fast Acting haze remover gel. Use clock-wise motions of a soft bristled brush to apply Fast-Acting Haze Remover Gel vigorously on both sides of the mesh. Wait no more than 5 – 10 minutes before rinsing or it could damage your mesh. Never let it dry on the mesh.


Rinse the screen. To prevent chemical splash backs, flush the screen thoroughly with low pressure water, then use a commercial power spray gun to remove ink stains and stencil residues.

Health and Safety Information
