UNC Logo History: Comparing Design Changes

Before you start

The University of North Carolina has used several visual marks over time, including letterforms, seals, and athletic symbols. Historical references may appear as scanned photographs, printed programs, video frames, or modern digital files. Before comparing versions, decide whether you are working from a single image, a set of screen captures, or a printed scan. The process is local: open files on your device and inspect them at a controlled size. No special service is required.

Step-by-step instructions

1) Gather two or more clear views of the marks you want to compare. Use the highest available resolution for printed scans and avoid heavily compressed video frames when possible.

2) Open the images side by side in an editor or viewer that supports zoom. Most desktop and mobile photo tools allow zooming with a slider, pinch gesture, or keyboard shortcut.

3) Align the marks by scale and orientation. If one image is much larger, reduce it to a similar viewing height. Do not judge small details until both images are close in size.

4) Compare one element at a time: letter shape, spacing, outline weight, interior detail, and surrounding border or shield shape.

5) For color marks, place the images on the same neutral background. Differences in lighting or paper color can exaggerate a design change.

6) Save a labeled copy of your comparison view if you plan to share the result. Keep the original files unchanged.

Check the output

A useful comparison shows the same feature in both versions without forcing them to match. If a difference is only visible at extreme zoom or after heavy compression, treat it as uncertain. Historical scans can lose fine lines or shift color, so a visible change in a copy is not proof by itself that the original mark changed.

Common problems and next steps

If a low-quality scan hides detail, switch to a cleaner capture or a larger available file rather than sharpening the image. Sharpening can create edges that were not in the source. When colors seem different, compare the same file on another screen only if the screen is the likely cause; otherwise keep the conclusion limited to the files you have.

For timestamps and official usage periods, rely on published university records rather than image appearance alone. A design may appear in promotional material before or after its formal adoption date.
