Bad Logo Changes: How to Evaluate a Redesign Before and After

What counts as a bad logo change

A logo change is a bad change when the new mark is harder to recognize, harder to reproduce at real sizes, or weaker as production artwork than the mark it replaces. Preference is not the test. The test is whether identity, geometry, lettering and file fitness hold up in the same conditions the old logo already had to survive.

A vector logo is artwork built from paths: outlines defined by points, straight segments and curves, rather than a grid of pixels. Path geometry is that construction in practice—how the shapes are drawn, whether curves stay smooth, whether fills overlap or knock out, and whether strokes are still live or already expanded into outlines. Typography handling is how lettering exists in the file: live, editable type; converted outlines; or a mix—and whether spacing, alignment and weight survive reduction. A file extension such as SVG, AI, EPS or PDF is not proof that the content is vector-only, editable, or cleared for reuse.

What a before-and-after comparison has to show

Place the previous lockup and the proposed lockup in the same frame: same background, same approximate visual size, same crop. Then read the pair as artwork that must print, reverse out, sit in a favicon-sized square, and sit on a wide sign. A redesign can look decisive in a pitch deck and still fail those jobs.

Recognition: can someone who knew the old mark still name the organization from the new one at a glance, without the wordmark as a crutch.
Distinctiveness: does the new shape collide with a generic icon, a competitor, or a category cliché that the old mark avoided.
Proportion: did the mark get stretched, optically lightened, or crowded so that the old balance of symbol to type is gone.
Contrast: does the new drawing hold on white, on black, and on a mid-tone, or does it depend on a gradient, a photo, or a colour that will not be present.
Reduction: at small size, do counters, hairlines and gaps fill in or disappear.
Lettering: did custom or carefully spaced type become a default cut, uneven tracking, or a weight that collapses when reversed.
System fit: can the new mark lock up with existing sub-brands, or does it only work as a hero image.

Visual judgement of “better” or “worse” is interpretation unless the organization has written identity rules that the new mark must meet. Where those rules exist, treat them as documented requirements. Where they do not, treat size, colour and contrast notes as design recommendations, not as specifications.

How to run the evaluation and confirm the result

Start with both versions as the actual artwork files, not screenshots of a presentation. Confirm you have permission to open and compare them. Do not assume a vector container holds only vectors, or that opening the file grants a right to redraw or redistribute the mark.

No application version, menu path or export preset is supplied here, so the checks below are outcomes you can observe in any competent vector editor. If a delivery depends on a named app’s commands, verify those commands against that version before you treat them as the brief.

Ordered actions

Open the old logo and the new logo at 100 percent zoom on a neutral ground, then again at a small on-screen size and at a large on-screen size.
Turn colour off: view both as one-colour positive and one-colour reversed. A change that only works in full colour is incomplete as a logo.
Inspect the new drawing’s paths: select outlines and look at anchors and handles. Note stray points, open paths that should be closed, overlapping fills that were meant to be a single shape, and strokes that have not been expanded if the handover requires outlines.
Inspect type: if lettering is still live type, note the font names, weights and whether any glyphs are missing or substituted. If lettering is outlined, check that counters are clean holes, that overlapping letters are merged or left overlapping on purpose, and that optical alignment of caps, punctuation and word space still matches the old lockup.
Check construction logic: symbols built from circles, squares and consistent stroke weights should still read as a system. Arbitrary warping, 3D bevels, drop shadows and embedded photographs are common sources of a “new” look that will not survive one-colour, small size or recutting.
Export or save a test in the formats the use actually needs (for example a single-colour mark for print, a simplified mark for small digital use). Re-open those outputs and confirm they still match the master, rather than trusting the source filename.

Path, type and export checks that finish the job

Check	Pass looks like	Fail looks like
Paths	Closed, economical outlines; smooth curves; fills that match the intended solid shapes	Open paths, broken joins, hidden duplicates, raster images sitting inside a vector file, live effects that rasterize on output
Typography	Intended font or a faithful outline conversion; even spacing; counters that stay open when small	Substituted fonts, auto-traced letterforms, tracking that falls apart, hairline serifs that vanish in reverse
Colour	Named or clearly specified solids that survive one-colour conversion	Unspecified RGB decoration, gradients required for the idea to read, colours that only work on one background
Export	Re-opened output matches the master at the intended use	Missing fonts, split shapes, clipped artwork, a pixel image saved with a vector extension

The evaluation is complete when you can state, in one pass, whether the new mark is still identifiable as the same organization, whether its path geometry and type will reproduce, and whether the delivered files actually contain that artwork. If any of those three fail, the change is a bad change for use, even if the concept board looks finished.

Gaps this comparison cannot close by itself

This guide does not name a specific redesign, designer, date or stated intention, and it does not attach measurements, colour values or software settings that were not supplied. Legal clearance, trademark conflict and licence to modify a mark are separate from visual quality. A before-and-after that fails recognition or production still fails even when the files are technically tidy; a before-and-after that looks sharper still fails if the new paths, type or exports cannot be used.
