Emulsion Pinholes

Emulsion pinholes.

If you are experiencing pinholes in your newly exposed screens, you should look into your degreasing process.  If there is anything left on your screen after the previous reclaiming process, you will experience pinholes, fish-eye, poor adhesion, and many other negative impacts.  Always use as much water as possible when degreasing to be sure all of the chemicals and grime are out of your screen.  Do keep in mind that pressure washers do not put out nearly as much water as it appears.  Other causes include a dirty exposure glass and dust where your screens are drying.
