Viewing single post of blog Notes on the chlorophyll printing process

This blog post is an archive of things that didn’t work. Realising the 3 facts described below had a very strong impact in my research.

I hope you enjoy my archive of failures and that it saves you some time if you decide to practice the bleaching technique. Enjoy!

 

UV lamps

UV lamps release very little light compared to the Sun, and they mainly release UVA light. In order to bleach a leaf one needs UVB light mainly, as well as large amounts of visible light.

If you use a UV lamp, it will cook your leaf, as this lamps release much more heat than light!

 

Black back printing frame

The majority of the photographers working with printing process use printing frames with black backs.  It doesn’t work for this process as it helps to rise temperature, and again it will cook the leaf in your printing frame rather than bleaching it!

 

One layer of acetate

One needs to print the same image twice onto different acetates. This is very important because the Sun bleaches everything including the ink pigments on the acetate. If one wants to have a successful outcome then it is mandatory to have a double layer.

I hope sharing my research journey with you was useful and encouraging :)
