Partial spray drying within the logo causes which defect?

Explanation:
When a tablet has an embossed or recessed logo, the coating solution can flow and dry inside that recess during spray coating. If drying happens while material is still present in the logo area, droplets can accumulate and dry there, filling the recessed impression. This partial drying inside the logo fills the recess and bleaches out the sharpness of the logo, producing Logo Infilling. Other defects like rough coating, delayed dissolution, or tablet twinning come from different issues in film formation, disintegration behavior, or mechanical sticking, not from material filling an embossed area. To prevent this, optimize spray parameters and drying conditions to reduce coating droplets lingering in the logo recess.
