You will have to do the compensation yourself based on your observed
printed output.

Hi,

If I create a rectangle shape with a width of 10 * 72 / 25.4 and then print
it and measure the width with digital calipers, the actual width is 10.27 mm
not 10 mm.

Can anyone tell me why please and how to print a rectangle of 10 mm width?

I actually want to get the precision down to under 1/2 mm.

TIA
Lisa
