-Digital printing works beautifully for designs with photos, illustrations, rich color variety, gradients, and transparency — though solid colors also come out looking great.
To ensure the best results for your digital print, please follow these simple file guidelines when creating and submitting your artwork:
-300 DPI resolution for sharp, high-quality prints
-Transparent background (especially for .png files)
-Trim the image to your actual design — the file edges should match the edges of your artwork
-Save your file as a .PNG or .JPG-
