Photoshop & Illustrator
When submitting raster art (Photoshop) please set up your files to the actual size you want to print with a resolution of at least 300dpi. It is not necessary to "flatten your image", but remove any layers with extra information.
All fonts should be converted to outlines. To convert text to outlines, go Select > Select All. It doesn't matter if other graphic elements are selected. Select Type > Create Outlines from the menu.
If you need help with any specific artwork questions please call or email us and we will be happy to assist you.
