Dehaze Screen Printing Mesh

  Dehazing screens is removing the stain or "ghost image" in the screen mesh that can be left after printing. The haze or ghost stain left in the mesh from the previous print job can be confusing when registering your screens on press for the next print job.

Common things that cuase ghost stains in your screen mesh.

1. Ink- letting the ink set in the screen to long after printing is one cause for stains in your screen mesh. Another is the type of ink- we have found that water based and discharge ink has stained our mesh more then regular plastisol ink

2. Improper exposure time. Under exposing your screens can lead to ghost stains in your mesh from your ink. So dial in your exposure time and help reduce ghost stains and needing to spend excessive time dehazing.

Dehazing chemicals can be caustic and very toxic. We personally like to use biodegradable chemicals for dehazing our screens and removing the old "ghost image".

  The process to dehaze your screen is very simple and easy. To begin just simply wet the screen down with water in the washout booth. Next, using a spray bottle, or whatever the dehazer you are using calls for, begin to mist the old ghost stain in the mesh. Using a scrub pad, begin scrubbing the stain in the mesh. After scrubbing the dehazing chemical into the mesh rinse the dehazer and mesh off. By now the ghost image should be removed. Some stains may be harder to remove then others and it may take a couple of times cycling through to completely remove old ghost stains. If you don't remove the stain 100% don't fret, you should still be fine. The next step will be degreasing.
