Photogravure Conservation
Biological

FIOLOGICAL DETERIORATION IS THE RESULT OF ATTACK by flora and fauna. Paper can be a very inviting material for all manner of insect and rodents. Preventing such infestations usually centers on creating as inhospitable of an environment as possible by keeping storage areas clean and free of moisture and food. Possibly of greater concern for the collector, various species fungi can exploit trace inorganic components in paper to sustain their metabolism. Such interactions can eventually cause local red/brown stains to develop on paper commonly referred to as "foxing." Again, the key to prevention is maintaining cool, dry, conditions as fungal growth accelerates as temperature increases and at humidity levels consistently above 60%.
