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.
