In a revision of the Photogravure page, I added several references to photogravure technique, including one from my own website. This triggered a COI tag. However, an inspection of the several pages of technical instructions on photogravure etching at my site should indicate that the content is appropriate and not excessively self-promotional. The information should be of use to anyone contemplating doing photogravure, which is the purpose of the detailed instructional pages. Should any viewer feel otherwise (or agree) after reviewing the relevant pages, I would be pleased to answer any questions.
