Service introduction
Accuracy and clarity, together
Specialist illustration has to be correct first and easy to understand second — we design for both.
We work from your references, sketches and subject-matter guidance, and share drafts for expert review before finishing. Labels, callouts and colour coding are planned so the visual teaches at a glance.
Technical accuracy
Illustration where the facts matter as much as the drawing
Medical, scientific and technical illustration carries a different burden from decorative art. If the structure is wrong, the picture is wrong, however well it is drawn.
We work from your sources: papers, scans, CAD files, specimen photographs, engineering drawings. Every illustration goes through a factual review with you before it goes through an aesthetic one. Labelling, scale bars, orientation markers and legends are set to the convention of your field rather than to a general design preference.
- Factual review pass before any aesthetic refinement
- Labelling and conventions matched to your discipline
- Vector output that stays sharp at journal and poster scale
