Vectorization, explained by people who build the engine

Practical guides on turning raster images into clean vectors: logos, gradients, JPEG noise, cutting files, quality checks and batch work.

• How to vectorize a logo (and get a file a printer will accept) — A practical, step-by-step guide to turning a small PNG or JPG logo into a clean SVG, PDF or EPS with sharp corners, exact brand colours and editable curves.
• PNG vs SVG: what designers, printers and developers actually need — When a PNG is fine, when only a vector will do, and how to convert between them without losing the sharpness of your artwork.
• Fixing a blurry, low-resolution logo without redrawing it — How sub-pixel edge reconstruction recovers smooth shapes from tiny, blurry or pixelated logos — and where the limits are.
• Why your vectorized logo comes out in the wrong colours — and how Curvora avoids it — Phantom colours, muddy blends and shifted brand tones are the commonest vectorization complaints. What causes them, and how a colour-aware engine prevents them.
• Getting real gradients out of a raster image — How smooth shading becomes linear and radial gradient fills in SVG, PDF and EPS instead of dozens of banded shapes.
• Preparing vector files for laser cutting, vinyl plotters and CNC — What cutting software expects from a file — outlines, not fills — and how to export DXF or stroke-only SVG that cuts cleanly.
• Vectorizing a JPEG without tracing the compression artifacts — JPEG ringing, blocking and colour bleed turn into hundreds of stray shapes in naive tracers. Here is how noise-aware vectorization keeps them out.
• How to judge vector quality before you download (a 60-second checklist) — Zoom, wireframe, node counts and the loupe: five quick checks that separate a clean vector from a messy trace.
• Vectorizing vs AI upscaling: which one do you actually need? — Two different tools for two different problems. When an upscaler is right, when a vectorizer is right, and why the vector route is often both smaller and sharper.
• Batch-vectorizing an icon set or a folder of logos — Queue dozens of images, keep consistent settings, and download everything as a ZIP — or automate the whole thing with the API.
• Preparing a logo for embroidery digitising (what the digitiser actually needs) — Embroidery software follows outlines, not pixels. Turn a small JPEG logo into clean closed shapes a digitiser can stitch — and avoid three common rejections.
• From a pencil sketch to a vector: jewellery drawings for CAD, catalogues and casting — A scanned or photographed jewellery sketch is grey, uneven and full of paper texture. How to turn it into clean line work for CAD, a catalogue or a laser engraver.
• Getting a cuttable DXF out of an image (CNC, laser and vinyl) — A cutter follows closed paths. What that means when tracing a part from an image, why scale is what everybody gets wrong, and how to check a DXF before cutting.
• One crest, every use: preparing a school or college emblem for uniforms, print and the web — A crest gets embroidered, printed, engraved, put on a website and blown up for a banner. How to make one clean vector master that survives all of it.
• Artwork a screen printer will not send back (T-shirts, hoodies and tote bags) — Screen printing splits your design into one screen per colour. What that means for the file you send, why colour count is a price, and what to check first.
• Getting a sign made from the only logo file you can find — Sign makers and vinyl cutters all ask for vector artwork. How to make it from a small logo file or a photo of the old sign — and what to check at full size.
• Turning a sketch into a clean tattoo stencil — A stencil prints at exactly the size it goes on skin. How to get even, unbroken line work from a photographed or scanned drawing, and what to fix first.
• Cutting files for cake toppers, card and craft vinyl — Cricut, Silhouette and lasers all follow paths. How to turn a design into a file that cuts cleanly, holds together, and lifts off the mat in one piece.
• Clean floor plans for listings, brochures and boards — Floor plans get reused at every size, from a phone listing to an A1 board. How to turn a scanned or screenshotted plan into line work that stays sharp everywhere.
• Die-cut sticker artwork: the design, and the line it is cut on — A sticker is two things: a printed design, and a separate path the blade follows. How to prepare both — and why the cut line is not the edge of the artwork.
• A wedding monogram that survives foil, letterpress and a 2 cm seal — Foil dies, letterpress plates and laser-cut seals are all made from paths. How to prepare a monogram that works at every size an invitation job asks for.
• Sponsor logos on an event backdrop: why one bad file ruins the wall — A backdrop is printed two metres wide from logos sponsors email at 300 pixels. What to ask for, and where tracing stops helping.
• Delegate badges: artwork that stays sharp at 90 mm and at a glance — Badges are printed small, read fast and produced in hundreds. How to prepare the artwork so names stay legible and the mark stays crisp.
• Printed tickets and wristbands: artwork, numbering and the tear line — Tickets are printed in long runs with sequential numbers and a perforation. Why the design belongs in vector, and what must stay out of it.
• Venue signage: arrows that work at ten metres and on a phone screen — Wayfinding at an event is printed large, cut from vinyl and shown on screens. One vector set does all three — here is how to prepare it.
• Photo booth props: turning a drawing into something a cutter can follow — Props are cut from board or acrylic, so the file has to be closed paths with no thin necks. How to prepare artwork that survives the evening.
• Paisley and floral motifs: one drawing, printed, cut and projected — A hand-drawn motif ends up on backdrops, stencils, menu cards and cut panels. Line art mode turns the scan into geometry that scales to all of them.
• A boutique mark that works on a bag, a box and a 12 mm stamp — Small fashion businesses use one mark everywhere: bags, boxes, foil, stamps and labels. Why it has to be vector, and how to check the smallest size.
• Hang tags: the artwork, the hole, and the thing everyone forgets — A swing ticket is die-cut, punched and strung. Which parts of that belong in your artwork file, which belong on their own layer, and why the shape has to be a path.
• Woven labels: designing for thread, not for pixels — A woven label is made of threads on a grid, which sets a hard floor on detail. How to prepare artwork, and how to know in advance what will be lost.
• Printed carry bags: one file, several sizes, no reprints — Paper bags are ordered in three sizes and printed from a flat die line. Why the artwork has to scale without redrawing, and where the fold lines go.
• Shop window decals: cut vinyl is a path, not a picture — Vinyl is cut, weeded and applied by hand. Which means strokes must be outlines, islands need thought, and the file has to be geometry from the start.
• Rubber stamps: solid black, no grey, nothing thinner than the rubber — A stamp is a raised rubber surface, so the artwork has to be pure black and white with no soft edges. How to prepare one from a logo you already have.
• Border motifs: repeating artwork that has to be exact — A border repeats dozens of times along a length of cloth, so every small error repeats with it. Why the motif belongs in vector first.
• Hand block prints: keeping the character while cleaning the file — Block prints have deliberate irregularity. How to digitise a motif for screens, digital printing and catalogues without flattening what makes it a block print.
• Seamless repeats: the tile has to meet itself exactly — A repeat that is one pixel out shows as a line down every metre of cloth. Why vector tiles are easier to keep exact, and how to check the join before you print.
• Placement drawings: telling the embroiderer exactly where it goes — A yoke, a chest mark or a sleeve motif needs a placement drawing as well as artwork. What belongs on it, and why it should be vector.
• Appliqué patches: a cut edge, a stitched edge and a clean outline — A patch is cut from fabric and stitched to the garment, so the outline is both a cut path and a stitch path. How to prepare artwork that serves both.
• Corner motifs: one drawing, mirrored four ways — Corner designs are drawn once and reflected. Vector geometry keeps every corner identical; a photograph of a corner does not.
• Colour separations: one screen per colour, and the overlap between them — Screen printing needs one file per colour, plus a deliberate overlap so small misregistration does not show. How vector artwork makes both straightforward.
