Your high resolution digital art looks great on glass.
When printing logos, tag lines, icons, and other corporate branded artwork, it is always best practice to use vector digital files. Line work such as grid systems and schedule layouts as well work best with vector files. Using this type of file will give sharp edges and crisp lines to your finished product.
When it comes to photographic images, its best to provide us with 300 dpi jpgs or pdfs. Make sure to flatten all images if the artwork was created in photoshop. This will prevent any transparencies from showing up and causing the print to fail and look unfinished.
