Introduction
"Drawing illustrations is fun, but the submission process is a burden..."
"I thought the size was right, but it was rejected for the 10px margin rule."
"I saved it as a transparent PNG, but the background looks incorrect."
If you have experienced these issues, let's solve them efficiently using EzStampify.
Common Causes for Rejection
While the review process is faster now, rejections due to "format issues" are still common. Here are two critical points:
① The '10px Margin Rule' Drawing right up to the edges of the 370x320px canvas may lead to rejection. Use the 'Auto Padding' setting in EzStampify to create the correct margins automatically.
② Transparency and Artifacts Unpainted areas or tiny leftover pixels can ruin the look in Dark Mode. Use 'Background Removal (AI)' to cleanly process edges and remove microscopic artifacts.
Recommended App Settings
For ibis Paint Users
- Draw Large: Drawing at 2x size (740x640px) ensures better line quality when scaled down.
- Saving: Always use 'Save as Transparent PNG'.
- Layer Tip: Use an opaque white background while coloring to spot leaks, then hide it before saving.
For CLIP STUDIO PAINT Users
- Vector Layers: Use vector layers for lineart to maintain quality.
- Hide Paper Layer: Ensure the 'Paper' layer is hidden during export.
- Exporting: Use 'RGBA (Color)' for .png exports.
