What makes a logo vector print-ready
Printers want three things from a logo file: edges that stay sharp at any size, colours that match your brand, and as few separate shapes as possible. A traced PNG often fails the second test, because most tracers average colours and your orange comes out slightly brown.
SVG Harbor snaps every palette colour to the most common real pixel in your file, so the hex value in the SVG is the hex value in your logo. Layers are stacked to avoid hairline gaps that show up on large prints.
When should you hire a designer instead?
If your only copy is a tiny, blurry image, a tracer can only follow what’s there. In that case a designer can redraw the logo by hand. For most logos with a reasonable source file, the converter gets you a print-ready result in a minute.
