4K Print-Ready Panels Replication

I’ve attached three PDF artworks, each file name already states its exact print dimensions. I need those very same designs prepared as separate, press-ready panels in true 4K resolution. No alterations, colour tweaks, or cropping—just a flawless, high-definition rebuild so every line prints razor-sharp at large format without a hint of blur or pixelation.

What I’ll call a success:
• Three individual files delivered in both PDF (preferred for the print shop) and PNG.
• Pixel dimensions and aspect ratios must match the measurements in the file names precisely.
• Minimum 300 DPI (or higher if required to achieve full 4K) across the whole canvas.
• Colours embedded in CMYK and RGB versions so I can switch depending on the printer’s profile.
• Zero visible artefacts when zoomed to 400 %.
