Hi everyone,

I am currently experiencing an issue with my cyanotype traditional printing process, specifically concerning the edges of my prints. Despite my efforts to mask the edges with an opaque material during exposure, I consistently encounter a visible edge around the emulsion after the development bath. I have attached some pictures to provide visual context for the problem.

To apply the emulsion, I use a soft brush or sponge, laying down a generous amount of emulsion on the paper. This technique has resulted in prints that are rich and free from visible brushstrokes. The black areas of the negative clear out wonderfully, but unfortunately, the edges do not. While the presence of an analog feel in certain instances is intriguing, I would like to understand why this occurs and how I can control this parameter.

I have experimented with various techniques to address this issue, including adjusting exposure times, distances between the light source and the print, as well as modifying the washing process. However, the problem persists.

I would greatly appreciate any advice, suggestions, or insights from those who have encountered a similar issue or possess expertise in cyanotype printing.

Best regards,

Alessandro
