Preparing Images for Large Format Printing

Image Resolution for Big, Beautiful Prints

Print resolution determines how sharp and detailed your photo appears once enlarged. While screens display images at 72 ppi (pixels per inch), prints need much higher pixel density for crisp results.

Recommended Print Resolutions

• Close viewing (2–3 ft): 300 ppi for premium sharpness.
• Wall displays viewed from afar: 150–240 ppi is often sufficient.
• Fine art or gallery prints: Up to 360–400 ppi for maximum fidelity.

To check your file’s readiness, divide its pixel dimensions by your intended print size. For example, 6000 × 4000 pixels printed at 20 × 13.3 inches = 300 ppi — perfect for a sharp, professional print.

DPI vs. PPI: What’s the Difference?

DPI and PPI sound similar but refer to different parts of the workflow:

Simply put, your photo’s PPI ensures quality input; your printer’s DPI ensures faithful output. Together, they determine print sharpness.

Sharpening for Large Prints

Large prints magnify even the smallest blur, so sharpening is crucial—but subtlety is key. Use a three-step approach for best control:

1. Capture Sharpening: Correct minor lens softness in your RAW processor.
2. Creative Sharpening: Gently enhance the subject’s focal points (eyes, edges, or textures).
3. Output Sharpening: Fine-tune for paper type and print size, often at a lower strength but wider radius.

For control, many pros use Photoshop’s High Pass filter or Lightroom’s print-specific sharpening options. Always inspect at 100% zoom and save a dedicated “print-ready” copy.

Your Louisville Large-Format Print Workflow

Louisville offers top-notch printing studios specializing in large-format photography. Whether you’re preparing fine art pieces or business displays, follow this simple workflow:

1. Manage Color

• Calibrate your monitor with a colorimeter monthly.
• Work in Adobe RGB or ProPhoto RGB for better color depth.
• Ask your lab for their ICC profile and soft proof your image before exporting.

2. Format Your Files

• Save as TIFF or PSD for uncompressed, high-quality output.
• Keep layers if needed for final tweaks, but flatten before submission if the lab requests it.
• Confirm file size limits and preferred resolution with your print provider.

3. Communicate with Your Printer

• Specify paper or medium—canvas, metal, or archival photo paper.
• Discuss finishing touches like lamination or float mounting.
• Share your expectations for color temperature (neutral, warm, or cool).
