Stock Vector EPS 10 Pre-Flight & Submission Guide: Passing Inspection Every Time
A practical, verified pre-flight guide for Shutterstock, Adobe Stock, and Freepik contributors. Avoid common rejections caused by unexpanded live fonts, stray anchor points, locked layers, and color space mismatches.
1. Why Stock Marketplaces Still Require EPS 10
In 2026, modern vector design software supports advanced features like variable typography, native SVG 2.0 gradients, and complex 3D meshes. Yet the world's leading microstock platforms—including Shutterstock, Adobe Stock, Freepik, and iStock—still mandate Illustrator 10 EPS (or CS6+ AI) as the standard vector delivery format.
Why does a legacy format from 2001 remain the industry benchmark?
- Universal Software Compatibility: EPS 10 opens reliably across any design application—CorelDRAW, Affinity Designer, Inkscape, legacy Illustrator editions, and commercial print RIPs—without proprietary feature locks.
- Deterministic Transparency Flattening: Because PostScript Level 2/3 lacks native alpha channels, Illustrator bakes blending modes and opacities into deterministic vector polygons, preventing unexpected rendering discrepancies on customer machines.
- Standardized Ingestion: Stock agency ingest engines rely on robust PostScript parsers to index bounding boxes, color spaces, and vector metadata across millions of assets.
2. The 7 Most Common Vector Rejections & How to Fix Them
When stock review queues inspect your files, automated validation scripts and human reviewers reject non-compliant submissions. Here are the top 7 rejection triggers and their exact Illustrator fixes:
2.1 Unexpanded Live Fonts (Text Frames)
The Problem: If any text element in your artwork is live, customers without that exact font installed will see missing font substitutions and broken typography.
Ctrl+A / Cmd+A) > Type > Create Outlines (Ctrl+Shift+O / Cmd+Shift+O). Verify in Type > Find/Replace Font... that no fonts remain.
2.2 Stray Anchor Points & Unpainted Paths
The Problem: Accidental clicks with the Pen Tool create single-vertex isolated points with 0 fill and 0 stroke. Automated microstock parsers flag these as uncleaned stray points.
2.3 Locked Layers and Hidden Objects
The Problem: Hidden draft layers or locked background objects can prevent customers from selecting or editing elements, leading to immediate quality rejections.
Ctrl+Alt+2 / Cmd+Opt+2) and Show all (Ctrl+Alt+3 / Cmd+Opt+3). Delete unused layers and guides before saving.
2.4 Low-Resolution Raster Effects (72 DPI Blur / Shadow)
The Problem: When applying Drop Shadows or Gaussian Blurs in documents defaulting to Screen (72 ppi), EPS 10 rasterizes effects into pixelated 72 DPI bitmap blocks.
2.5 Color Mode Mismatches (CMYK vs RGB)
The Problem: Major microstock agencies (Adobe Stock, Shutterstock, Freepik) require digital vectors to be submitted in RGB color mode. Saving in CMYK causes dramatic color shifts and muddy preview thumbnails.
2.6 Dimension Requirements: Megapixels (MP) vs Megabytes (MB)
The Problem: Stock portals enforce strict Megapixel (MP) thresholds calculated by multiplying artwork pixel width × height:
- Adobe Stock: Artboard dimensions must be between 15 MP and 65 MP (e.g. 5000×3000px = 15 MP).
- Shutterstock: Artwork bounding box must be between 4 MP and 25 MP (e.g. 2000×2000px = 4 MP).
- Freepik: Preview JPG must be between 2000px and 10,000px on its longest side (4 MP – 100 MP).
2.7 Overflowing Artwork Bounding Boxes
The Problem: Elements extending far beyond the artboard boundaries inflate the EPS file's bounding box, resulting in tiny, shrunken catalog thumbnails.
