Clean Up a Scanned Logo in Photoshop

The short answer

Photoshop can turn a rough scan of a printed logo into a clean, usable image. You can straighten it, flatten paper texture and background tone, remove specks, firm up edges and recolour it. What Photoshop cleanup produces is still raster artwork: a grid of pixels at a fixed resolution. It is not a vector logo, and saving the file as PSD, PDF or EPS does not change that. If you need artwork that scales to any size with crisp edges, such as for signage, embroidery, vinyl cutting or a brand master file, treat the Photoshop cleanup as a reference or stopgap and plan a vector redraw.

No details about a specific logo, scanner or Photoshop version were supplied for this article. The guidance below therefore covers general Photoshop techniques and principles rather than results measured on a particular file. Menu names can vary between Photoshop versions.

What you are working with

A scan of a printed logo is a photograph of ink on paper. Along with the logo, it captures paper grain, uneven lighting, slight rotation, dust and ink spread around the edges. Printing processes can also add halftone dots or a moiré pattern that the scanner records. Each of these issues needs a different fix, and none of them can be fully solved by sharpening or enlarging the image.

It also helps to separate three kinds of file that are often confused. Vector artwork is made of mathematically defined paths and fills. A raster image is made of pixels. A file such as a PDF, EPS or SVG can hold vector paths, embedded raster images, or both. A logo that looks like a vector file because of its extension may simply contain a pasted bitmap. You can only confirm editable paths by opening the file in a vector editor and inspecting it, not by its filename.

Start with the best possible scan

Cleanup is easier when the source carries as much detail as possible. Scan at a high resolution, so curves and small lettering have enough pixels to work with. Scan colour logos in colour, even if you later reduce them to a few flat colours. Use grayscale for single-colour marks. Place the print flat on the glass and close the lid, or weight it down, to reduce shadows and warping. If the print has a visible halftone pattern, check whether your scanning software has a descreen option before you scan, because removing a dot pattern afterwards is harder.

A practical cleanup workflow in Photoshop

• Duplicate the background layer, or convert it to a Smart Object, so the original scan stays untouched.
• Straighten the logo with the Crop tool's Straighten option or the Ruler tool along a baseline or edge that should be level, then crop away excess paper.
• Use Levels or Curves to push the paper toward pure white and the ink toward solid colour. This removes most background tone and grain.
• For a single-colour logo, try a Threshold adjustment to force every pixel to black or white, and adjust the slider until thin strokes survive without the edges filling in.
• Remove isolated specks with a light Dust & Scratches or Median filter, or by hand with the Brush, Eraser or Spot Healing Brush. Strong filter settings will round off sharp corners.
• Repair broken or bleeding edges by hand on a separate layer, zoomed in, using hard-edged brushes and selections.
• Isolate each colour with Select > Color Range or the Magic Wand, refine edges in Select and Mask if needed, and fill each selection with the correct solid colour on its own layer.
• Remove the white background if you need transparency, and save a layered PSD as your working master, plus a PNG with transparency for everyday screen use.

Work on separate layers where possible, so a heavy-handed adjustment can be undone without starting again. Check the result at full size and at the size it will actually be used, since minor edge flaws can be invisible on screen but obvious in print.

Fixing a pixelated logo

A pixelated logo is a low-resolution raster image that has been enlarged until the individual pixels show as blocks or blurry steps. Photoshop cannot recover detail that was never captured. Enlarging the image only creates new pixels that are estimated from the old ones.

Within that limit, there are useful options. In Image > Image Size, enlarge with resampling turned on and try the detail-preserving resampling methods. Then apply Threshold or Levels to snap soft, stepped edges back to solid shapes. For colour logos, rebuild each colour area from a selection filled with flat colour, rather than keeping the blurry edges. Camera Raw also includes an Enhance feature with super resolution, which can produce a smoother enlargement. How well any of these methods work depends on the source, and simple, bold logos usually respond better than fine lettering or thin outlines.

If the enlarged result still shows lumpy curves or uneven letterforms, more Photoshop work tends to give diminishing returns. That is usually the point to redraw the logo as vector artwork.

Getting from Photoshop toward vector artwork

Photoshop does have some vector tools. The Pen tool and shape layers create real paths. A selection can be converted with Make Work Path, and paths can be exported for use in Illustrator. For simple geometric marks, carefully drawn Photoshop paths can be a reasonable basis for a vector version. Paths generated automatically from a scanned selection, however, tend to carry the scan's irregularities and contain too many anchor points. They need significant correction before they are clean enough to use.

For most logos, the more dependable route is to place the cleaned-up scan in a dedicated vector editor as a locked template. You then redraw the shapes with deliberate anchor points, consistent curves and accurate alignment. Auto-trace features can give a quick starting point, but their output should be reviewed and corrected, not treated as finished artwork. If the lettering is set in an identifiable typeface, it is often cleaner to set the text with the licensed font and convert it to outlines than to trace letterforms from a scan.

Which approach fits your use

Use | Photoshop cleanup alone | Vector redraw recommended

Website, social media or slide decks at fixed sizes | Usually adequate if the cleaned file is large enough | Optional

Office documents and small print items | Often adequate at the printed size | Helpful for consistency

Large-format print, signage, vehicle graphics | Risky, as edges may soften when enlarged | Yes

Vinyl cutting, engraving, embroidery digitising, screen printing separations | Not suitable as the production file | Yes

Brand master file handed to designers or printers | Not suitable as the only master | Yes

Permissions and ownership

Being able to scan or download a logo is not the same as having permission to modify or reuse it. Logos are commonly protected as trademarks, and the artwork and any fonts used in it may have their own copyright or licence terms. Cleaning up your own organisation's logo, or one you are commissioned to restore, is routine. Redrawing or altering someone else's mark for your own use is a different matter. If the logo belongs to another party, confirm you have permission for the specific use. Check whether the owner can supply an original vector master before you rebuild it, and make sure any font you use to reset the lettering is properly licensed.

Gaps in this guidance

Without a specific logo, scan or output requirement, this article cannot say whether a particular file will clean up well enough for its intended use, what resolution it needs, or how long a redraw would take. Those depend on the source quality, the logo's complexity and the final output method. Your printer or production vendor can tell you which file types and resolutions they need.
