We can print from most any file.
We recommend JPG for photos.
100-300 PPI resolution at the size you want to print
So for example if you want to print something 3×4 inches
3×4 inch file size at 72 PPI gives below average quality
3×4 inch file size at 100 PPI gives average quality
3×4 inch file size at 200 PPI gives great quality
3×4 inch file size at 300 PPI gives the best quality
For shape cutting signs and vinyl graphics EPS or AI files.
Make sure to convert fonts to outlines before saving.
