Seamless Pattern Enlargement

I’m working with a fabric print that currently measures 240 mm × 130 mm and need it expanded to a final artboard of 2500 mm × 929 mm. Instead of a simple scale-up, the design must be tiled so the pattern flows seamlessly across the new dimensions—no visible repeats or mismatched joins.

You’ll receive the original artwork in high resolution. Keep the colours and brightness exactly as provided; no tonal tweaks are required. All I’m after is a flawless, repeat-ready file suitable for large-format printing.

Deliverables
• One print-ready file at 2500 mm × 929 mm (preferred formats: layered PSD, AI, or high-quality TIFF)
• Seamless pattern work verified at 100 % zoom with no hard edges or artefacts

I’ll review by placing the file into a 2500 mm × 929 mm template and zooming in for any seams, so please double-check before sending. If you’re comfortable with pattern tiling in Photoshop or Illustrator and can turn this around quickly, this should be a straightforward job.
