I have noticed, since [Lr] 5 and thru to 6.3, the font rendition in the watermarks are fuzzy in Windows. If I use the same watermark definition on Mac, the rendition is sharp. Has anyone else noticed this?
My solution, currently, is to export a catalog from Windows and open it on my Mac to export the images! What a pain in the butt.
Can you show the watermark settings that you have used to create/apply watermark.
Also post a screen shot of the results from both Mac and Windows.
