(End credits, Excel Saga) Yes, today I have a very sad tale to share in my cyanography experiments. 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. Because there is no cellulose for the Prussian Blue to bond with, the washing inevitably destroys the image, meaning that you cannot preserve the image long-term. 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
Haven't bought a hp printer in years, I have always found them to be expensive repair, tend to break easily, refuse to update drivers and they have always self destructed if you put non hp cartridges in them anyway.
ReplyDeleteGlad that my hp printers are way too old to be affected by this.
ReplyDeleteHad already decided that if i get a new printer it will be an epsom and this sort of thing just reinforces that decision.
