I've dabbled a little bit in Van Dyke prints and can offer you a bit of help with your problem. The chemicals used to Van Dyke prints are not sensitive, I believe, to visible light which is why the paper can be coated under tungsten (indoor) light. Van Dyke paper is, however, sensitive to ultraviolet light. Generally, Van Dyke prints are made by contact printing a black and white negative in sunlight. Of course, the larger the negative the better.
