High-quality prints start with proper design preparation. This guide explains DPI, color profiles, and transparent PNG best practices so your T-shirt and hoodie prints look professional and vibrant every time.
In print-on-demand and apparel production, a flawless print isn’t just about the printer—it starts with your design files. Many beginners overlook critical settings like DPI, color profiles, and file formats. Understanding these ensures your art translates perfectly from screen to fabric.
1) DPI: Dots Per Inch
- **Recommended:** Use 300 DPI at actual print size. Lower resolutions may look pixelated when enlarged. - **Check Your Canvas:** If your print area is 12x16 inches, set your file to 3600x4800 px at 300 DPI. - **Scaling Caution:** Upscaling small images won’t add detail—always create art at or above target resolution.
2) Color Profiles: RGB vs. CMYK
- **Upload in RGB:** POD platforms expect RGB files (e.g., sRGB) because their systems convert to printer profiles automatically. - **Preview in CMYK:** Use a CMYK preview or soft proof to anticipate how colors may shift on fabric. - **Avoid Neon & Pure Blacks:** Extreme colors may not reproduce well—use safe color ranges for consistent results.
3) Transparent PNG Essentials
- **Format:** Save as PNG-24 with transparency enabled. - **No Backgrounds:** Delete all background layers to avoid unwanted boxes or colors. - **Edge Clean-Up:** Zoom in and ensure edges are smooth to prevent white halos. - **Layer Safety:** Flatten visible layers before export to reduce file size and avoid compatibility issues.
4) File Naming and Organization
Use descriptive file names like krasswerk_hoodie_logo_12x16in_300dpi.png. Organize by product type and size to avoid errors. Consistent naming conventions make bulk uploads and revisions easier.
5) Mockup Testing
Test your PNG on realistic mockups (Placeit, POD platform mockup generators) to spot issues like low resolution, color shifts, or jagged edges. Adjust before final upload.
6) Common Pitfalls to Avoid
- Exporting at 72 DPI—will look blurry on large prints.
- Forgetting to remove hidden background layers—may cause unwanted boxes.
- Using CMYK-only files—can lead to unexpected color results on POD systems.
- Neglecting to proof colors under different lighting conditions.
7) Workflow Tips for Teams
- Use shared folders (Google Drive, Dropbox) for version control. - Keep a master template with correct canvas size, DPI, and color settings. - Communicate guidelines clearly with designers or freelancers to maintain quality across collections.
