How We Restore Antique Maps for Print

The scans that archives publish are made for research, not for a wall. They include the scanner bed, the ruler, the library’s stamp and barcode, and the colour cast of whatever lamp was used. Folds cast shadows; the paper’s age reads as a muddy yellow on screen. Print that as it is and you get what most marketplaces sell.

1. The scan

We start from the highest-resolution file the archive offers — usually a TIFF or JPEG2000 master of 100 to 1,000 MB — never from a web thumbnail. Before anything else we record the archive’s item-level rights statement; if it doesn’t allow commercial reuse, the map isn’t listed, however good it looks.

2. The restoration

Working at full resolution, we crop to the sheet, correct levels per colour channel, and neutralise the cast only partly — the warm paper tone is part of the map and stays. Library stamps, barcodes, dust and scanner artefacts go. Fold shadows and stains are reduced where they distract and left where they belong to the object’s history. Then a gentle sharpening pass, and a proof at print size to check that the smallest lettering holds.

What we never do: redraw lines, recolour areas, “clean up” the sea, or invent detail that isn’t in the scan. The restoration notes on each product page say exactly what was done to that map.

3. Fitting the sizes

Every scan has its own proportions. Instead of cropping a map to fit a standard frame, we offer only the sizes whose proportions match the sheet within 3 percent — or, where the proportions are off by more, the map floats whole on a toned aged-paper margin. And a size is only offered where the scan gives 200 dots per inch or more; 24×36 needs roughly 4,800 pixels on the short side, so a small scan is simply not sold that large.

4. Printing and framing

Prints are made on archival matte paper (200 gsm, acid-free) with pigment inks that resist fading, by our print partner’s facility nearest to you — US orders print in the US, UK orders in the UK, EU orders in the EU. Framed prints use a solid wood frame with an acrylic front (lighter and safer in transit than glass) and arrive ready to hang. Canvas is stretched on a wooden bar with the image continued around the edge.

The before-and-after slider

On the home page and on many product pages you can drag between the archive scan and our restored version. The “before” is the archive’s own preview; the “after” is the file that goes to the printer.
