Quick Tips: Ghost Images

Ever wondered why your screens keep a faint “ghost” image in your screen? I’m going to quickly share with you why this happens and how to eliminate it.

Ink passes in and out of mesh openings during the printing process. After printing, most printers put the dirty screen in the rack and move on to the next job. The dirty screen has leftover ink particles sitting in the mesh openings and “staining” the mesh. Once the screen is reclaimed a ghost image remains in the mesh and the printer then has to either go back and use a dehazing product to get the stain out or emulsifies the hazed screen and leaves the screen with the image embedded into the mesh. By taking a few seconds after the finish of a print run to clean out the mesh openings, a printer can save time, money, and effort in their cleaning process.

Once you are finished with a print run, immediately take ink remover and wipe out the exposed mesh in your stencil on your screen. This removes the ink and doesn’t allow it to sit and stain the mesh. Even if you plan to use the screen the next day, it is wise to go ahead and clean out the stencil to protect again the staining.

When your screen is taken to be reclaimed, the mesh will have little or no haze. By taking the simple step of immediately removing ink from your stencil after a print run, you will encounter much less need to use a dehazing product, much less time and effort spent dehazing your screens, and you will be able to print more ink in one stroke due to clean mesh!
