Product illustration has to do two jobs: look great and work perfectly in production. Art directors and manufacturers don’t have time to fix misaligned vectors, messy layers or the wrong colour mode. A beautiful drawing that fails at the printer is a problem, not an asset. A clear, repeatable workflow is what makes illustration reliable enough for commercial use.

Constraints help creativity
Many artists fear that technical limits will kill the creative spark. In practice, limits often make work stronger. A knitted sock pattern might allow only five colours and a set pixel grid. A label might have a tiny space and a die-cut shape. Working within those rules forces clear choices, which suits a bold, minimal style.
My workflow, step by step
- Read the specs first. Size, bleed, colour mode (CMYK, Pantone or RGB), file format, print method, colour limits.
- Thumbnail sketches. Small, quick ideas to agree on direction.
- Rough at final size. Check that details survive at real scale.
- Clean line art or vectors. Tidy paths, closed shapes, no stray points.
- Colour with a fixed palette. Named swatches matching the print method.
- Organise layers. Clear names and groups, with text, art and die lines separate.
- Preflight. Check bleed, resolution, overprint and fonts.
- Export in every format the client needs, with a short readme.

Why a process helps when energy varies
A fixed checklist means quality doesn’t depend on how I feel that day. On low-energy days I can still follow the steps and produce files that are right. That reliability is what clients notice. It’s also part of building a stable freelance practice; see Freelance Illustrator Stability.
Common file problems to avoid
- RGB files sent for CMYK printing, which causes colour shifts
- Missing bleed, which leaves white edges after trimming
- Low-resolution images inside vector files
- Unoutlined fonts the printer doesn’t have
- Hundreds of unnamed layers
Colour is the most common surprise. Screens show light (RGB) while printers use ink (CMYK), so bright purples often print duller. The CMYK colour model explains why. I check key colours against a printed swatch book before final delivery.
Printing companies publish guidance on these. The preflight overview on Wikipedia is a good general reference.
Keeping your style in commercial work
Precision doesn’t mean losing personality. My characters keep their slightly strange, outsider feel even on a sock or a cereal box. Style lives in shapes, colour choices and ideas, which survive any format. For more, see Product Branding Narrative and Visual Storytelling.
Frequently asked questions
Vector or raster for product illustration?
Vector for logos, labels and anything that needs scaling. Raster can work for textured art if resolution is high enough for the final size.
What files should I deliver?
Usually a layered source file, a print-ready PDF and web-ready PNG or JPG. Confirm with the client.
