Preparing Print Photos: Color Modes & File Formats Explained

At Kastleman Media, we often get asked about the best settings and file formats when submitting photos for printing. Whether you're printing cherished family photos or high-quality art, getting the right settings can make all the difference. To help you prepare your files for the best results, we want to dive into two key areas: color modes and file formats.

RGB vs. CMYK: Which is Best for Printing Photos?


Color modes are essential when printing photos, and two of the most commonly used are RGB and CMYK.


  • RGB (Red, Green, Blue) is the color mode used for digital screens like your phone, computer, or TV. It offers a wider range of colors, perfect for on-screen viewing.

  • CMYK (Cyan, Magenta, Yellow, Black), on the other hand, is specifically designed for print. It limits the color range slightly, but it’s optimized for ink and paper.


When it comes to printing photos, CMYK is the preferred option. This mode ensures that colors translate correctly from your screen to the final printed version. RGB files may appear too bright or overly saturated when printed, as printers can't replicate the full RGB color spectrum. So, when submitting your photos for print, it’s best to convert them to CMYK to ensure accurate, high-quality results.

File Formats: Which One Should You Use for Printing Photos?


Another important factor is the file format you choose. The four most common formats are JPG, PNG, TIFF, and PDF. Each serves a different purpose:


  • JPG (or JPEG) is the most commonly used format for photos. It compresses the file size, making it easier to share or upload, but this compression can reduce quality slightly. JPGs are great for everyday photo printing where ultra-high resolution isn’t necessary.

  • PNG supports transparency and offers higher quality than JPG, but it also creates larger file sizes. While PNGs are great for web use, they’re not typically used for printing because of their larger size and lack of print-specific advantages.

  • TIFF is often considered the best format for high-quality printing. It is a lossless format, meaning no data is lost during compression. TIFF files are much larger than JPGs, but they retain every bit of detail, making them ideal for professional-quality photo prints.

  • PDF is commonly used for documents but can also be useful for printing photos, especially in situations where text or additional design elements are involved. PDFs preserve image quality while maintaining the layout, which is especially useful for projects like photo books or posters.

  • PSD is a Adobe Photoshop file format. Here at Kastleman Media we love working with PSD files as this will offer the absolute best quality. Printing directly from Photoshop will result in the least amount of lost detail and color.


For the best results when printing photos, TIFF is usually the top choice for professionals, while JPG is more than sufficient for everyday prints. PSD files is also a great option!
