You remember last time, I shared this: Well, I have experimented further with inkjet photo paper, and made some very unpleasant discoveries along the way. The first is the streaking - without using a non-contact application method, I am not going to avoid it. The gel surface is just too fragile. So if I want to persist with this, it will be out with the air-brush. I somehow doubt I am going to find spray-cans of cyanotype sensitiser, after all.  The second is in washing.

This also means that you end up including the un-exposed chemicals in the scan, which adds considerable grain and loss of contrast - especially in the high-tones of the inverted image.  This second issue is essentially insoluble, which is a pity, as it would h
