Anastatic printing is a historic reproduction method where an original drawing or printed page is transferred to a zinc plate. The original ink is treated with acid and gum so it repels water and attracts fresh ink, essentially creating a relief facsimile without resetting type or re-engraving. It was a standard technique for reprinting older books and duplicating maps before photographic reproduction methods took over.
Heard on the job
We found an anastatic reprint of the county map, which explains why the line quality looks slightly heavier than a true copper engraving.
Insider tip
Because it relies on transferring existing ink, anastatic copies often show slight thickening of fine lines compared to the original letterpress or engraved source.
