After setting up your design using the Chile Template (Making sure you keep all important information within the "safe" area of the template), you will "export" or "Save as" a CMYK, 300DPI, JPEG.
Make sure you DO NOT have the layer with the Chile Template turned on. The "exported" or "Saved as" JPEGS should be exactly the way you want them to print.
Next you will need to delete (or turn off the layers of) all Objects, shapes, or text that you DO NOT WANT to have the spot UV on. Also be sure to remove (or turn off) any effects like drop shadows or glows, and make sure to bring all opacity back to 100%.
The last step will be to select all objects, shapes, or text and change them to 100% Black (C=0 M=0 Y=0 K=100). Taking care not to move any of the objects, shapes, or text. These "spot files" should match up perfectly to the files from step 2. Finally you will "export" or "save as" a CMYK, 300DPI JPEG.
