Old posters are tricky things to digitize. Clean them up too much and you lose the paper texture, the slightly off registration, the ink bleed that makes them feel like they came from a real press. Clean them up too little and you cannot print them anywhere. The goal is not to make a vintage poster look new. The goal is to make it look like it did on the day it was printed, before sixty years of sunlight and thumbtacks got to it.
Understand what you are preserving
Before you touch the file, decide what actually matters about this poster. For a travel poster, it is usually the flat color fields and the bold lettering. For a concert poster, it might be the grain and the hand-drawn type. For a product ad, it is often the illustration itself. Write that down. Every decision after this should protect that quality and sacrifice everything else.
Separate restoration from enhancement
These are two different jobs and mixing them is the most common mistake. Restoration fixes damage: tears, foxing, stains, fading. Enhancement changes the image: sharpening, color grading, upscaling. Do restoration first on a copy of the scan, then apply enhancement to the restored file. If you enhance first, you will amplify the scratches right along with the detail, and they become almost impossible to remove afterward.
Our style and conversion tools handle the enhancement side well, but they work best when the input file is already free of physical damage.
Rebuild the color from a known reference
Faded posters have lost saturation unevenly. The blues have gone green, the reds have gone pink. Do not just crank the saturation slider; that makes the surviving colors overwhelming. Instead, find a reference image of an intact copy of the same poster, or if none exists, use a color chart photograph made under the same lighting as your scan. Match the paper white first, then correct the ink colors against it. Getting the paper white right fixes more of the faded look than any other single step.
Handle the lettering last
Lettering is where conversion tools most often produce artifacts. Curved type gets warped, thin strokes get thickened or broken, and any drop shadow gets blurry. Work on the lettering as the final pass, at the highest resolution you have, and compare the result against the original at 100 percent zoom. If the tool has a strength setting, keep it low for text-heavy areas and only push it higher for the illustration and background.
Keep the paper texture
A poster with zero texture reads as a digital recreation, not a restoration. Leave some grain in. A light overlay of the original paper tone, even at low opacity, does more for authenticity than perfect digital cleanliness. Print shops can often add a paper stock that matches, so a little grain in the file composes nicely with the physical print.
Export for the printer, not for the screen
Convert to CMYK before exporting, check that your blacks are rich black rather than flat black for large dark areas, and save at 300 dpi at the final print size. Keep the RGB master file intact for any future screen use. The screen version and the print version will look different, and that is expected and fine.
Start with a single damaged poster on our image conversion tool, work through the restoration and enhancement passes separately, and keep a copy of every intermediate file. Vintage work is slow and reversible decisions matter, because you rarely get a second scan of a poster this old.
