Pradip Malde and Mike Ware are cited for their work on pages 43-44
There are two corrections to be noted, both on page 43:
- “The Ware-Malde process calls for fixing, clearing, and washing of the print using ethylenediaminetetraacetic acid (EDTA), Kodak Hypo Clearing Agent, and water.” We recommend the ‘fixing’/clearing cycle as described in this Platinum and Palladium Printing summary
- “Fully processed prints are usually heat dried.” – while I have not tested for this, I do find it best to air dry, and then, for vellum papers, to further flatten them in a dry mounting press.
