Hi all, I am fairly new to alternative printing and I have been wanting to get consistent results with my cyanotypes (soon to be salt prints). So i contacted a local screen printing company that makes their own uv exposure boxes and purchased one of their units. I have done a bit of experimenting with it and it seems woefully underpowered for digital negatives (one step print took around 2 hours to expose!). I have attached a photo of the box. Currently there are 6x T5 8W tubes. Now I can always add more T5 Tubes to the unit or I could start from scratch and build something bigger and more powerful myself. What are your thoughts?
