1. You might be using ink with inadequate chemistry or formula.	1. Make sure the ink you are using is right for the substrate. Adjust as needed to find the right match.
2. Surface is not receptive to ink.	2. Treat / activate the substrate or use coating primer / varnish if possible. Consider changing ink chemistry or formula.
3. There is not enough binder. Ink has become too thin.	3. Add fresh ink and / or resin binder or shellac. Bring ink viscosity to optimal and stable level.
4. Contamination of substrate surface.	4. Check the rest of the substrate stock. Inform the supplier. Consider wash coating before next printing run.
5. Problems with the drying process. Temperature or air volumes are too low in the dryers.	5. Consider increasing drying temperature. Turn up air volume or air velocity in the dryers.
6. Ink viscosity is too high.	6. Reduce ink viscosity to suit your needs.
