Creating a beautiful map poster is only half the battle—getting it printed or displayed properly is equally important. This guide covers everything you need to know about file formats, resolution, color management, and printing options to ensure your PosterMapsPro creations look their absolute best.
Understanding Resolution and DPI
Resolution determines how sharp and detailed your printed poster will appear. Here's what you need to know:
- 72 DPI: Perfect for digital display (websites, social media, digital frames)
- 150 DPI: Good for large format prints viewed from a distance
- 300 DPI: Professional print quality for close viewing
- 600 DPI: Ultra-high quality for premium prints and fine details
Quick Resolution Guide
For a 24"×36" poster: 300 DPI = 7200×10800 pixels. Always calculate your needed pixel dimensions before exporting to avoid pixelation.
File Format Selection
Different formats serve different purposes. Choose wisely based on your intended use:
PNG
Best for: Digital use, transparent backgrounds, web display
Pros: Lossless compression, supports transparency
Cons: Large file sizes
Best for: Professional printing, vector graphics, archival
Pros: Scalable, professional standard, small files
Cons: Limited editing options
JPEG
Best for: Photos, web use, smaller file sizes
Pros: Small files, universal compatibility
Cons: Lossy compression, no transparency
SVG
Best for: Vector graphics, infinite scalability
Pros: Infinitely scalable, small files
Cons: Limited photo support
Color Management
Colors can look different on screen versus print. Understanding color spaces helps ensure consistency:
Color Space Options:
- sRGB: Standard for digital displays and web use
- Adobe RGB: Wider color gamut for professional printing
- CMYK: Print-specific color space for commercial printing
Print Color Tip
Always request a proof print for important projects. Colors can vary significantly between different printers and paper types.
Paper and Material Selection
The right paper can make or break your poster's final appearance:
Popular Paper Types:
- Matte Paper: Reduces glare, professional appearance, good for detailed maps
- Glossy Paper: Vibrant colors, sharp details, but can reflect light
