RE: Inkpress Transparency Film
Not in my experiance. It really is a robust and easy to work with alternative to Pictorico. I have had zero problems with drying or pooling of ink. My negs are super (in fact the best thing about my images actually :))
I use this product for gum prints and cyanotype. For gum my exposure time is around 45 seconds in Summer months. This is with Lyson dyebased inks and a PDN negative by the way.
I think it's a really good product. The only problem is - it's so cheap!!
