Print Your Own Images: Technical Guide

Image formats

Our Photo Lab can process JPG and TIFF images. If your imaging software saves files in a default format different from JPEG or TIFF, please export the files in the proper format before uploading them.

Data sizes & print resolution (DPI)

Do not attempt to increase the size of the image before uploading.

The maximum print size is determined by the size of the original by taking the size in pixels (your camera’s “megapixel” size), dividing it by the print resolution (“dots per inch”, “DPI”) and thus determining how large we can print the image without noticeable quality loss.

All images will be checked before print to verify that they can safely be printed at the size requested.

RGB vs. CMYK Color Space

When you save an image in Adobe Photoshop or similar photo editing programs, you can choose which color model to use. You will need to use the RGB option rather than CMYK. The color depth per color channel needs to be at least 8 bit (for a total of 24 bit of color depth). This is the default for most cameras.

Please go to the photo lab where you can upload your images for printing.
