The most important thing to remember is that your artwork file needs to tell our printers where to cut to make a shape out of your product. So, unless you have artwork that has just a head and no background color, you want to make sure you create a 'cut' line in the artwork.
How do I make a Special Cut line in Adobe Illustrator?
The easiest way to create a cut line is to use a software program like Adobe Illustrator. The Pen tool works great for tracing that cut line. Make sure to select a bright color for your cut line, something unique to the other colors in the photo, something that really stands out. Once you complete the tracing step, you need to open up the Swatches panel (Windows -> Swatches) and make a few changes (see photo example above and read steps just below here).
1) Swatch Name: Cut (name your Swatch cut).
2) Change the Color Type to Spot Color
3) Change the Color Mode to CMYK
Now click on OK, save your file and you are done! Go upload your artwork directly to our printers!
