Technical Standards & Production
Technical specifications matter. A beautifully designed portfolio produced at low resolution will feel unprofessional when printed or viewed on a quality screen. Production standards establish the difference between an amateur portfolio and a professional one.
Digital vs. Print Standards
| Parameter | Digital Standard | Print Standard |
|---|---|---|
| Resolution | 72–150 PPI | 300+ DPI |
| Color Mode | RGB | CMYK |
| File Size Limit | 10–20 MB (max) | Unlimited |
| Bleed | N/A | 1/8" (0.125") on all sides |
| File Format | PDF, JPEG, WebP | PDF (with embedded fonts) |
PDF Production and Ghostscript Optimization
When exporting your portfolio to PDF from InDesign or similar software, use these Ghostscript presets to balance file size and quality:
- /screen: 72 DPI, smallest file size (2–5 MB for 30-page portfolio). For teaser emails or quick digital sharing.
- /ebook: 150 DPI, balanced file size and readability (5–10 MB). Acceptable for digital viewing on tablets and laptops.
- /printer: 300 DPI, maximum quality (10–20 MB+). For standard desktop printing or professional printing services.
COMMON MISTAKE: Maintaining a 300 DPI standard during the creation phase is critical. It is much easier to downsample a high-resolution file for digital use than to attempt to upscale a low-resolution file for print. Start at 300 DPI, then create lower-resolution versions as needed for specific use cases.
File Organization and Version Control
Maintain separate master files for different contexts:
- Portfolio_Master_2026.indd: Your primary working file at full resolution (300 DPI)
- Portfolio_Print_2026.pdf: Optimized for printing (300 DPI, CMYK color)
- Portfolio_Digital_2026.pdf: Optimized for screens and email (150 DPI, RGB color, ~10 MB)
- Portfolio_Website_2026.pdf: Compressed for web (72 DPI, RGB, 2–5 MB)
Printing Considerations
If printing your portfolio professionally, work with a printer who understands design specifications. Provide a print-ready PDF with all fonts embedded, images at 300 DPI, and color profiles clearly specified. Request a proof before full production. Paper selection affects the final appearance: matte paper reduces glare and feels more refined; coated paper enhances color saturation and image detail.
