What Resolution (PPI/DPI) should I make my Images for Printing?

For the best results make sure your files are at the right resolution before uploading them to print

To get it spot on everytime. Here are a few suggestions.

CANVAS:

Minimum DPI or PPI for your images printed on Canvas at the finished size: 150ppi (240ppi is preferred, 300ppi is the maximum)

Paper & Aluminium HD Metal:

300ppi is preferred. (210ppi as a minimum).

Check your Image Size in Photoshop in the: IMAGE > IMAGE SIZE menu

Make the image the correct size. E.g. If you're ordering a 20x30" Canvas then size your image to 20x30" in Photoshop at the correct PPI (min. 150ppi) 300ppi is the max.

Can you upscale your images?

Yes, this is a very basic technique to 'resize' your images generally in a program like Photoshop or Affinity Photo or Lightroom.

You can generally upscale your images (if they're good quality) to approx. 400% if required.
