Upscale Artwork for Large Print

I will supply a PNG of my existing artwork and simply need a much higher-resolution version that can be printed at 300 cm × 280 cm without any loss of clarity. The style, colours and composition must remain exactly as in the original—no text overlays, colour shifts or other added elements—just a clean, faithful enlargement.

Your task is to upscale or faithfully recreate the piece so it holds sharp detail at full size, ready for professional wall-art printing. If vector rebuilding, AI upscaling or meticulous manual redrawing is needed, feel free to use the method you trust most; the end result should look identical to the source file when viewed at the intended dimensions.

Deliverables:
• One print-ready file (TIFF or high-quality PDF) sized 300 cm × 280 cm, 300 dpi or best-practice resolution for large-format CMYK output.
• Source or working file (PSD, AI, or equivalent) so future tweaks remain possible.

Kindly confirm the turnaround you can commit to, along with any printer specifications you may require.
