Photographers who aspire to enter the fine art market understand that professional presentation and authentication play an important role in preparing their work for sale. Hahnemühle’s Authentication Product Range gives photo artists a complete package, including their world-renowned archival papers and portfolio boxes and special pre-printed Certificates of Authenticity. In addition, there’s now a free online print registry service for establishing provenance. Hahnemühle inkjet papers have earned high regard among gallerists and curators, thus the association with the brand itself shows the artist’s regard for their work. Other tools include the Hahnemühle Signing Pen Duo, which combines a pigment liner and graphite signing pencil that will not bleed through any paper surface, and various specialty coating sprays for print protection, preservation and presentation.
