Sorry, I completely forgot to thank you for the reply, it came in just as I was leaving for a few days and I’ve only just got back to looking at this issue.
I’ve tried what you suggested but my interpretation of the licensing requires each tile requires a watermark. The images rendered with this method only contain part of the watermark, or sometime none if the tile size is small enough. I did look at using a layout (thinking I could add the layout parameter at the proxy server) but I could not see anyway of dynamically setting the size of the logo so it filled 10% of the tile. Are there other tricks I could use? To summarise the my goal, render a graphic that fills a percentage of the requested tile at a particular zoom level.

Watermarking is fairly easy. The way I did it if memory serves; - Create a shapefile covering the entirety of the UK. - Style the shapefile with the watermark so that only the watermark is visible and somewhat transparent (20%?). - Use the watermark as the “top” layer in a layergroup with any of your OS datasets. It works quite well and gets included in all outputs, WMTS, WMS, cached or otherwise. You can see it in action here when you zoom in to 1:5k or closer.

The watermark is to cover 10% of the rendered image. This data only required when zoomed right in. I couldn’t find a way of doing this in Geoserver so I’ve made a modification to the watermarking to accept a zoom level and a ratio of the tile to resize the watermark logo to. The dataset in question is Ordinance Survey’s Master Map, so I’m sure other people must face similar watermark restrictions. Is there a way of doing the above with Geoserver and if not, is there a better way of implementing my changes as a plugin rather than the core? Lastly, if the answer to both of these is no, would such a change be of enough interest to warrant pursuing incorporation into Geoserver’s code base.
