Problem
Transparent PNG assets are composited against an unintended matte color before final export.
Solution
Root Cause / Diagnostic:
Exporting transparent cutouts or graphics using automated web export presets often bakes in an unintended default matte color (such as white or gray) around semi-transparent pixels. This produces an unsightly chalky border when placed over dark backgrounds.
Actionable Fix:
1. Set export matte settings to "None" in your export dialog, ensuring transparent alpha channels remain clean and un-matted.
2. Place a solid black or dark charcoal adjustment layer beneath all cutouts during the design phase to inspect semi-transparent edge pixels.
3. Zoom in to 300% along cutout boundaries to verify zero white or gray matte contamination around fine hair and edges.
Pro Tip:
Always design over a temporary dark backing layer; previewing cutouts against black instantly exposes unwanted white matte fringing before you export.
