The basic darling monograms license allows up to 250 impressions, usage above that amount requires a license upgrade, including derivative works.
What is an Impression Limit? While most folks plan to use this font for personal use, some buyers may wish to create and sell products using this font. To make it easier for those wishing to sell products created with this font, Tart Workshop is offering the added ability to purchase this license upgrade at the time you place your order.
By default, you're allowed to sell 250 items in total without any additional licensing required and should you intend to sell more items, additional levels of licensing can be purchased now or at any time in the future. To be clear, 250 items doesn't refer to how many different items you may create but rather refers to the number of total sales of any item or items created with this font.
Tart Workshop fonts or outlines created from them cannot be resold embedded in PDF documents specifically allowing 3rd parties to print with them.
If you have further questions for us or aren't sure what level of licensing is appropriate for your needs, please contact us directly. info@tartworkshop.com
