Sometime next week I will do a pour with less diazo sensitiser in it.

Clearing, drying, washing leaves a yellow stain but maintains the integrity of the transfer. Clearing and then washing works about the same.

2 clearing cycles and then immediately washing cleared the stain but I left my wedge soaking in the sink and when I came back 2 hrs later it had started to dissolve.

There is a balance that will work. Stain may not be a problem with some supports.

This is RC paper I am working with and only the coated side stains, not the back. Something in there is reacting with the diazo. Gelatine sized watercolour paper will probably be fine.

I am too busy now to spend time on this, but it is a workable option and I hope someone will be able to repeat my results soon.

Yes, non iodised salt was used.
