Subject: Re: [Homebrew_PCBs] Printer "drag shrink"

From: DJ Delorie <dj@...>
Date: 2009-03-24

I've stuck the thick Pulsar paper to regular paper and sent it through
my laser printers in the past. However, even on just bond paper my
printers shrink the print a little, about 0.5% to 1%. Are you seeing
a small even shrinkage, or random major shrinkage? Can you measure a
reference print and compensate? (assuming your software has that
feature, gEDA's pcb does). Oh - and measure the toner on the pcb, not
the toner on the printer, as the rest of the process changes the size
a little also.

However, I have had cases where "card stock" (100lb, 5x thicker than
standard bond) has problems getting through my current laser printer.
It depends.
