Preventing Ink Haze
Allowing ink to dry in the screens after printing will cause ink to dry in the knuckles of the mesh. This is true of plastisol, solvent base, water base, discharge and HSA inks. Excessive pressure and flashing create heat on the mesh, which open the pores of polyester mesh threads, allowing the ink to seep into the thread. Once cooled, the mesh will require either heat or haze remover to open the pores and allow the mesh to be be properly cleaned.
