Photographic archival boards

Normally the difference between photographic archival board and conventional archival board is the lack of alkaline buffer. This board is generally dyed natural white throughout, without optical brightening agents and with a pH of 7.0. Boards without alkaline buffer are generally used in direct contact with photographic layers. All KLUG-CONSERVATION boards, as well as the majority of other products of the company, have passed the Photographic Activity Test (PAT) compliant to ISO 18916.
