Upscale a print file you made
Enlarge your own art with a conservative tool, then inspect the line at full size.
Print shops ask for more pixels than a screen file has. An upscaler can bridge a modest gap. It cannot invent a drawing that was never sharp.

How to do it
- 1
Confirm you need it
Check the shop's current file guide for size and resolution. If the scan is already large enough, do not upscale. Scaling a file that is already big only makes a heavier file.

Start local
Run Upscayl on a copy. If you use Topaz or Photoshop Super Resolution, do that on a copy too. Keep the unscaled original.
- 3
Look at crossings and type
Zoom to 100 percent on line crossings, eyes, and any letters. Halos, doubled edges, and melted corners mean the scale is too aggressive or the wrong model.

Name the derivative
Save it as a print file with the size in the name. Do not overwrite the drawing.
