Image Lab: Neural Upscale
Quadruple an image’s resolution with AI so the laser burns real detail instead of a blur — ideal before dithering or vectorizing.

What this tutorial covers
- AI 4× resolution enhancement to 4K for sharper high-DPI engraving.
- One-click enhancement with Stop Waiting copy and durable result recovery.
- Split before/after comparison of original vs enhanced.
- Chain upscale into Photo Prep or the Fabricator without re-uploading.
1. Add the source image
Upload a PNG, JPG or WebP, choose a built-in sample, or use the shared Image Lab image. Upscale before dithering or vectorizing so later operations can use the additional pixels.
2. Review and run the upscale
Check the current upscale option and displayed charge before confirming the operation. Stopping the browser from waiting does not cancel a dispatched server job; use the result-recovery flow when needed.
3. Compare and download
Compare the original and enhanced views, especially fine edges and facial details. Download the enhanced image and check its dimensions before sending it to Photo Prep or another tool.
Validate the workflow on your machine
Treat the finished file as a controlled starting point, not a universal machine recipe. Confirm the artwork dimensions after import, verify focus and lens selection, and run a small test on scrap from the same material batch before committing the production piece. Change one variable at a time when tuning speed, power, frequency, line interval, or pass count. Record the machine, source wattage, lens, material finish, focus method, and final settings with the saved job. That short production note makes the result repeatable for the next operator and prevents a strong screen preview from being mistaken for a proven burn.
