Section 5: Restrictions on Use
Licensee may not use or permit the use of the Content beyond the terms of this Agreement without first obtaining an additional license. 

Licensee may not:
1.   Sublicense, sell, distribute, assign, convey, or transfer the Content, this Agreement, or any of its rights under this Agreement;
2.   Sell, license, or distribute its final product in such a way that allows others to extract or access the Content as a stand-alone file;
3.   Use or display the Content in any item intended for resale, license, or other distribution or for use in “print on demand” products, including but not limited to t-shirts, postcards, posters, mugs, artwork, etc.;
...

2. Physical and Electronic Items for Resale (additional fee applies)

Notwithstanding the restriction contained in Section 5 (3) prohibiting the use or display of the Content in any item intended for resale, license, or other distribution, and the restriction contained in Section 5 (6) prohibiting the use of the Content in any electronic template or application, Licensee shall, with respect to the Content, be entitled to:

 

(i) produce physical items for resale, including t-shirts, postcards, greeting cards, calendars, mugs, and mouse pads, provided the aggregate quantity is ten thousand (10,000) or less (“Physical Items for Resale”), and



(ii) produce electronic items for resale, including electronic templates or applications, provided these products are not intended to allow the re-distribution or re-use of the Content (“Electronic Items for Resale”). Collectively, Physical Items for Resale and Electronic Items for Resale shall be referred to as “Items for Resale”.
 

So a standard licence does not allow print on demand or use of images on products but an enhanced licence allows use of images on products but not if the products are offered 'print on demand'?
