Problem: Picture frame effect
| Cause | Remedies |
|---|---|
| The so-called “picture frame effect” can result when using structured powders with Corona guns. | This is effectively countered with the SuperCorona® set. It is simple to fit to existing Gema powder guns. To achieve optimum results after conversion the setting parameters for high voltage, and powder output must be reset. The PCC mode is another effective way to avoid the picture frame effect. |
