🎯 Target specs for print

Aim for 300 DPI (dots per inch) or higher when the piece will be viewed up close. That means an 8 × 10 inch print needs roughly 2400 × 3000 pixels before you export to TIFF or high-quality JPEG (LetsEnhance).

🤖 Step 1: Upscale with AI

1. Upload to LetsEnhance. Select the upscaler preset that matches your image (Smart Enhance for photos, Digital Art for illustrations) and bump resolution 4× or 8× while maintaining clarity (LetsEnhance).
2. Try Adobe Lightroom’s Super Resolution. Right-click your image → Enhance → enable Super Resolution to quadruple pixel count automatically—perfect for RAW workflows (Adobe Lightroom).
3. Experiment with Adobe’s Image Upscaler or Upscalepics for additional AI-driven boosts when you need more than 4× enlargement (Adobe Image Upscaler; Upscalepics).

🛠️ Step 2: Prep for 300 DPI output

1. Open the upscaled file in Photoshop, Affinity Photo, or another editor.
2. Set the final canvas size (Image Size dialog) to your print dimensions with Resample off so DPI adjusts automatically.
3. If you need a larger print than your upscale allows, enable resample with Bicubic Smoother and apply a minor (≤10%) increase, then re-run AI upscaling to avoid artifacts.

💡 Step 3: Sharpen and proof

• Apply a gentle High Pass filter (1–2 px radius) or Lightroom sharpening to restore micro-contrast.
• Soft-proof on screen or send a small test print to verify color and clarity.
• Export as TIFF or high-quality JPEG (quality 10–12) with the embedded profile used by your print lab.

🚀 Next steps

Once your low-res image is print-ready, store both the AI-upscaled master and the final DPI-specific export. Need to add extra background or adapt to alternate aspect ratios? Visit ImageStretcher.com to create additional space without stretching your subject.
