In-filling of Logos/Break Lines
Coating droplets are over-dried before contacting tablet surface, increasing tablet surface roughness and filling in the logo, thus reducing logo/break-line clarity.
ISSUE | CAUSES | RECOMMENDATIONS |
Coating Suspension | Suspension solids are too high, creating viscous suspensions that are difficult to atomize finely. |
|
Coating suspension is too foamy. Learn more. |
|
|
