Here the meaning of the acronyms:
Personal Use (PU) – A kit labeled with PU is for personal use only. This means you can use it for all kind of layouts, to upload in galleries on the Internet, and for other graphic projects but for your personal use only, not to create profit in any way.
Scrap for Hire (S4H) – A kit labeled with ‘Scrap for Hire’ is not just for personal use but also to scrap for someone else. For example: someone hires you to create a layout for her with the kit you have in your stock. You cannot make quickpages and sell them again and again – but you can create unique layouts for a customer. Often this means that you are also allowed to create notebooks, cards, and other items with the provided graphics. But for a specific meaning be sure to check the designer’s terms.
Scrap for Others (S4O) – ‘Scrap for Others’ is similar to ‘Scrap for Hire’ and means that you are allowed to give the layouts you created away to others.
Commercial Use (CU) – Products labeled as CU or ‘Commercial Use’ can be used for commercial projects. You can create with the items provided in the kit a new element or new papers and resell them. If a kit is appropriate for commercial use it can also be used for PU/ S4H or S4O.
Commercial Use for Commercial Use (CU4CU) – CU4CU products are seldom. Such kind of products allow the customer to create her own commercial use products from the provided elements or papers. With CU4CU items nearly everything is allowed except reselling them as they are.
