I would suggest that you don't use your at-home ink jet to print them, because the cost for the quality just won't be worth it. Look around for places that will do laser printing for you, if you shop around you might be able to find a fairly reasonable price (I pay 20p per A4 sheet when I do mine)
Vicky, thanks for the thoughts. I do believe you're right - I'm going to hunt down laser printing/ colour copying for sure.
Amber! I just received a copy of your CS 18 in the mail today (from Take Care distro here in Aust.) I'll have a look through it soon :D Thanks for sharing your process, that was super helpful.
I don't actually make my zines on my computer, I cut and paste and use the scanner part to colour copy them. But yeah, it's proving to be hella expensive. I just can't do it that way because I don't want to charge people for the expense, and it's way too much cost to run at a loss.
I've also ordered those two zines you recommended, on etsy (yesterday actually!) I was checking out Eleanor's website, I love her work. Thanks for all the help. Now to hunt down a reasonable priced copy shop.
