File Preparation for the Best Prints
To ensure your artwork or photography prints with exceptional detail, color, and clarity, please review the file guidelines below before submitting your files.
Accepted File Types
We accept the following file formats:
RAW, TIFF, PSD, JPEG, and PDF
- Best Option: If you’re a photographer shooting in RAW, submitting the RAW file is ideal. It gives us the most flexibility for color and tonal accuracy during preparation.
- Preferred: TIFF files are the next best option. They preserve the full color range and are excellent for any upsizing or fine-art printing.
- Also Accepted: PSD, JPEG, and PDF files are acceptable, especially for finished artwork or design layouts. Keep in mind that JPEGs are compressed, so they may not retain as much image data as TIFF or RAW files.
Color Space
For the most accurate color reproduction in print, please work in one of these color spaces:
- Preferred: Adobe RGB (1998) or ProPhoto RGB
- Not Recommended for Print: sRGB – this space is best for online or screen viewing, not for fine-art printing.
If you’re unsure, we can verify or convert your color space for you to ensure optimal results.
Resolution
Our optimal printing resolution is 360 DPI (dots per inch).
Files at 300 DPI are also perfectly acceptable.
- For best results, create or export your files at 360 DPI at the final print size.
- If your image is lower than 300 DPI, please do not resize it yourself — allow Thomas Editions to perform the upscale using our specialized software. This ensures the cleanest detail and smoothest tonal transitions.
File Delivery Options
You can send your files using our online upload system. Please note that upload times may vary depending on your internet connection speed.
If you’re local, you may also bring your files in person on a USB drive or external hard drive.
If you encounter any issues or need guidance, call us at (213) 258-5274. We’re happy to help you through the file preparation process.
Need to Print Larger?
If you can’t select the size you want during the ordering process, your file may need to be upscaled.
Please contact us — we can handle all upsizing in-house to maintain maximum quality.
