My go-to method is a mix of automated tracing and hand-cleanup — it’s the fastest path to crisp print-ready artwork. First I make sure the source clipart is as high-res as possible; if it’s a small PNG or JPG I upsize it a bit with smart upscaling or reconstruct the major shapes by increasing contrast and removing background noise in an editor. Then I open it in Adobe Illustrator and use Image Trace: start with the ‘Black and White Logo’ preset for silhouettes or ‘
High Fidelity Photo’ for detailed art, then tweak Threshold, Paths, Corners and Noise until the preview looks right. Hit Expand to turn the tracing into editable paths.
After that I spend time with the Pen tool and Direct Selection tool, cleaning stray points, simplifying shapes (Object > Path > Simplify), and joining open paths so everything is a proper closed shape. For printing I always convert strokes to
outlines (Object > Path > Outline Stroke), expand appearance of effects, and merge shapes with Pathfinder so the printer gets solid fills instead of messy overlays. I also switch the document to CMYK, set artboard size at actual print dimensions, and add 3–5mm bleed.
Finally I export to PDF/X or EPS depending on the print shop, save an SVG for scalable uses, and keep a layered AI file for edits. Don’t forget to outline text, use Pantone or CMYK swatches if spot colors are needed, and run a quick check at 100% zoom to catch hairlines. It’s oddly satisfying seeing a vectorized man clipart go from pixel mush to a clean,
Giant poster — I love that crisp result.
