Hey,,, I simply want to download adobe stock images for selling canvas printing on online.
I decided to make canvas printings just only depends on order.
I have planned to buy extended license of the image if I sell the printed image.
Is this okey with adobe rules?
It depends what you plan do to before buying the license. For example, do you intend to put mock-ups on your site made with the Adobe sample image?
If you use the Adobe API, you may offer the assets to your customers for on-demand printing. I suppose that would be the best option for your intended business.
There is also a provision in the licensing terms to use the watermarked picture for showing your customers how the design could be. You will need to look into the licensing terms.
Look here for more information on licensing: https://community.adobe.com/t5/stock/links-for-licensing-terms/td-p/11366788
(Disclaimer: As always with licensing, this is my interpretation of the rules. I think they are correct and advice is based on reading and interpreting the licence terms and on fair use for both the buyer and the artist/stock company, but I cannot rule out that my interpretation is wrong. I'm not an Adobe employee).
