Anyone doing alternative printing process? I have recently start doing kallitype printing and find it to be very interesting. Here is a quick summary gathered from various articles found online.
Kallitype is contact printing process in the iron-silver family. In this case we are using ferric oxalate and silver nitrate.
1. The Sensitizer is made up of silver nitrate at 10% and ferric oxalate at 20% mixed in equal amount. Then it is applied with a brush or rod on a suitable paper under week, artificial light. After application the paper should left to dry.
2. A suitable negative is then placed on top of the coated paper and weigh down with a thick piece of glass.
3. It is then exposed to UV Light. Sunlight can be used but it is inconsistent. A better option is to use UV tubes.
4. The print is then developed using a 20% sodium citrate solution for 8-10 mins.
5. Then it is rinse with water for 5 mins follow by 5 mins of EDTA (ethylenediaminetetra acetic acid tetrasodium salt) solution.
6. Toning may be apply at this stage.
7. Else the print is fixed using a hypo fixer for one min.
8. To reduce washing time, the print is immersed in a Hypo Clearing Agent solution for one min.
9. Wash for 20 mins before hanging up to dry.
