to supplement flyingarrow's handy link;
if you take the pdf to a local printers,
and use 180gsm cardstock (or 220gsm satin finish printboard);
the pdfs are already in 600DPI and CBYMK'd, all ready to print.
that will produce a card in the hand which feels similar to the 'official' ones,
and you'll know it when you see it hehe
you can also have them cut to spec at the time of printing,
so the only drawback can be, if it bleeds,
the edging can be a little rough as there's not enough bleedspace on that format of sheet etc..
the only problem can be,
a minimum run size, depending on the local printer's proclivities etc.
sometimes a local printer'll not want to touch 'lame sci-fi stuff'
with a tenfoot pole, other times, they'll be cool
Another option, is to use an in-home A4 or A3 printer,
though confer with your manual as to whether or not your printer will tolerate
180GSM-220GSM. You may also have to override the bleed area to adjust for the in-home laser printer etc,
and the feedrate - slightly slower tends to prevent any jarring/smudges
an option of last resort can be;
to print on regular paper, and laminate.
the laminated card is a similar thickness and size as a SWMinis statcard in a deckprotector sleeve.
its great to hear you're enjoying SWMinis,
and looking for more statcards - at this rate,
soon we'll be seeing some accompanying custom miniatures on the customs thread too.
good hunting, roblyon,
and let us know
how you get on.
