Flat Logo to 3D Vector

I have a simple, two-colour logo that I now need rendered with a realistic 3-dimensional look while still remaining 100 % vector so it scales perfectly for print and screen. The job is entirely in Adobe Illustrator—no raster or external 3D software—so I can easily edit colours later and keep file sizes lean.

Key points I need you to hit:
• The 3D treatment should combine subtle shading and lighting to create believable depth without adding unnecessary anchor points. I want the artwork as clean and efficient as the original flat version.
• Produce three colour variants straight from the same master file: CMYK for offset print, RGB for digital, and a balanced greyscale version.
• All shapes must remain editable paths; gradients or blends are fine as long as they stay vector.

Deliverables
1. Master .ai file with organised layers and minimal paths
2. Separate artboards or saved copies for CMYK, RGB and Greyscale versions
3. PDF/X-1a proof to confirm print fidelity

I’ll review the file by expanding all appearances to make sure no hidden raster elements slipped in, then run a pre-flight for spot colours and path count. If everything checks out, the project is done. Looking forward to seeing the logo pop in 3D while keeping that crisp vector precision.
