Hi,
Thank you for your answer.
The size of my watermark is 2993 pixels wide.
When I edit the watermark, if I click on the size cursor, the watermark is sharp. When I click on other settings or export photos, it becomes unsharp.
Here are two printscreens of the sharp and unsharp .
The one on the right look a little bit blurry, and that's the output watermark...
The watermark is originally 2993 X 488 at 118 pixels per cm (i'm european)
The one in the two examples above is huge 12000 X... at 600 p/cm
Any ideas?
