Homebrew PCBs

I just finished the electronics for a chorded keyboard, using strip
board, which kind of spills out of the keyboard housing.
Using kicad I designed a pcb that is a little less volume challenged.
I have an Epson 580, so I bought some 0.016" (about 1/64th") thick
single sided copper clad from goldmine-elec.com.

First I tried feeding the pcb material directly through (the 580's
print path has only one roughly 45 degree turn).  With proper
placement and applying force to the pcb at the right place and time,
it would feed, but the printer wouldn't recognize that a sheet had fed
through it.
So I printed to paper, cut a small piece of pcb and taped it over the
printout.
Worked great!  I stuck it into my toaster oven for two shots of
"medium toast", and it's fast on.  I did get puddling, and some
smearing, but I did no board prep, and was using black.  I understand
this is not cured.
I am about to make copies of the board on different layers, so I can
do a black, magenta, yellow and cyan copies, all at once, on prepped
pcb, and see how much toasting is required for them to cure.
Thanks for the good ideas
