When you choose the type of artwork you want to supply (PDF/Adobe Illustrator or Quick & Easy Upload), you are shown the following:
The current Quick & Easy Upload limits Artist names to 26 characters and Titles to 30 characters. Even with 30 characters, there could be issues because "W" takes more space than "I." It's currently impossible to predict how much space a certain text requires.
That means you must always check the text in the 3D animation to ensure it is correct. The 3D animation will appear once you have uploaded all images or PDFs.
Pause the animation and then zoom in with your mouse. You can rotate the product with your mouse (click and drag) or move it around by holding the space bar and using your mouse. Use the preset arrows to look at different positions (front, back, label, etc.)
If you need more than 30 characters for titles or artist names, select the Designer Upload option using Adobe Illustrator.
