AI Upscale for wide-format printing: Preparing the file for 8K (T

Task: Prepare a low-quality image (1200 px) for large-format printing on a poster sized 100x60 cm.
The problem with simple enlargement: When simply stretching the file in Photoshop, "pixels," "blurriness," and compression artifacts appear. The image looks cheap when printed.
My solution (AI Generative Upscale):
Instead of stretching, I used neural network upscaling, which restores and adds micro-details (textures, materials, light).
Technical results:
• Resolution increased nearly 6 times: to 8K (4600x8192 px).
• Achieved density of 208 DPI — this is the golden printing standard for interior printing of paintings and posters (provides crystal clarity without overloading printing equipment).
• The file delivered in professional TIFF format (CMYK) with optimized LZW compression without loss of quality — fully ready for printing on a plotter.
In the preview (in the small square), you can see the level of detail of the original compared to the final result.
I will save your photos or illustrations for quality printing in any size.
The platform does not allow uploading large images, so an example in JPG.
