During the order process, the Pictorem system checks the resolution of your uploaded image to ensure it is suitable for the print size you've chosen. 

They recommend printing at 300 DPI, but will accept a minimum of 150 DPI. 

If your image doesn't meet these requirements for the size you've selected, the system will let you know so you can adjust the print size or provide a higher resolution file. 

Pictorem strives to ensure that your final print meets the highest quality standards.
