Solved: using a loupe to check quality

in reviewing Piezo prints is it a good idea to use a 10x loupe to evaluate sharpness and tone?

Yes, a loupe can certainly help evaluate sharpness and print quality. We have some 5x loupes that we use for basic stuff, and a few 20X loupes for seeing EXTREME detail.
The loupe will be helpful when aligning the printer to the paper thickness you are printing on, to get the best alignment- therefore the best print quality (provided the nozzle check is clean and correct).

Happy printing~ Dana :slight_smile:
