Vector and raster artwork are not competing formats with one universal winner. They represent different kinds of information. Vector objects describe shapes mathematically; raster images describe color using a fixed pixel grid. Reliable print-and-cut files use each where it performs best.
Logos, text, borders and contour paths normally benefit from remaining vector. Photographs, painted textures and continuous-tone effects normally belong in raster images at sufficient effective resolution.
The short answer
- Use vector for logos, typography, technical lines, simple illustrations and cut paths.
- Use raster for photographs, scans, complex texture and pixel-based editing.
- Use PDF or another provider-approved format to preserve both types together.
- Check effective PPI, font handling, transparency and spot-color identity before export.
How vector artwork works
Vector graphics store points, paths, curves, fills and strokes. Because the shape is mathematical, it can scale without becoming pixelated.
Vector is well suited to:
- logos and icons;
- text and line art;
- borders and geometric graphics;
- named spot-color objects;
- contour cut paths;
- artwork reused at many sizes.
Vector does not automatically mean simple or trouble free. Extremely complex paths, thousands of nodes, live effects and transparency can slow RIP processing or rasterize during export.
How raster artwork works
Raster images contain a fixed number of pixels. They are appropriate for:
- photographs;
- scanned artwork;
- retouching and compositing;
- soft shadows and painted effects;
- complex continuous-tone texture.
Scaling a raster image upward reduces effective PPI. Resampling can create additional pixels, but it cannot restore original detail that was not captured.
Why cut paths must remain vector
A contour cutter needs a path it can interpret as geometry. A visible line inside a JPEG is only colored pixels; it is not a usable cutting instruction.
Create the contour as a clean vector path and apply the technical spot-color name required by the RIP. Preserve it through PDF export, then confirm that the RIP preview identifies it as a cut path rather than printed artwork.
Keep type and logos sharp
Text and logos are sensitive to soft edges and scaling. Keep them vector whenever possible. Before handoff, either embed fonts in the approved PDF workflow or outline them when the provider requires it.
Outlining prevents missing-font substitution but removes editability and can affect accessibility. Keep an editable source file even when the production copy uses outlines.
Mixed artwork is normal
A strong production file may contain:
- a raster photograph;
- vector logo and text;
- vector clipping path;
- named spot colors;
- vector contour cut path;
- rasterized shadows or transparency effects.
Adobe notes that PDF can preserve both raster and vector content. The goal is not to force the entire design into one data type, but to preserve the best representation of each element.
Watch transparency and effects
Drop shadows, glows, meshes, blending modes and transparency may be rasterized or flattened depending on the export standard and RIP. Problems can include:
- visible stitching lines;
- different color around flattened regions;
- lost spot-color identity;
- low-resolution effects;
- unexpected white boxes;
- changed overprint behavior.
Use the print provider’s PDF preset, inspect flattening or rasterized regions when relevant, and test complex effects before production.
Do not auto-trace every photograph
Image tracing converts pixel regions into vector shapes, but a photograph can become thousands of paths without gaining useful detail. The result may be larger, harder to edit and slower to RIP than the original raster image.
Trace simple logos or line art when no clean vector source exists, then simplify and inspect the paths. Do not treat tracing as a general resolution repair.
File-format considerations
| Format | Typical role | Watch for |
|---|---|---|
| Combined production artwork | Export standard, fonts, spot colors and transparency | |
| AI | Editable vector source | Linked images and application compatibility |
| EPS | Legacy vector exchange | Limited transparency and older workflow behavior |
| TIFF | High-quality raster production image | Larger files and no live vector cut path |
| JPEG | Photographic raster delivery | Lossy compression and no usable vector path |
| PNG | Raster transparency | RGB-oriented workflow and no contour geometry |
Preflight checklist
- Confirm final dimensions and scale.
- Keep logos, text and cut paths vector.
- Check effective PPI for placed raster images.
- Confirm linked images are embedded or packaged as required.
- Verify fonts, spot colors and overprint.
- Inspect complex transparency and raster effects.
- Remove duplicate or stray cut paths.
- Export using the approved PDF standard.
- Review separations and RIP preview.
- Print and cut a representative sample.
Bottom line
Use vector data for geometry that must remain sharp, scalable or cuttable. Use raster data for photographic and continuous-tone information. Preserve both through a controlled PDF workflow and verify what the RIP will print and cut.
