I decided to put together a masterpost of resources I know and have (mostly) used when making doujinshi, comics, etc. I hope this helps someone!
blambot - their free fonts are great for comics, and their license allows you to use them for self published works even if you’re making a profit
fontsquirrel - all fonts are advertised as being free for commercial use, but I’ve found quite a few that actually are not. has a lot of fonts, but please read the license first. if no license is included or if it’s not explicitly free for commercial use, don’t use it in printed works
eikou’s templates [JPN] - templates for comics are here if you don’t want to set up the guides yourself. however, if you’re printing, it’s probably best to use the templates/bleed specifications your printer provides
jetpens - they actually carry a lot of useful traditional manga drawing materials, like dip pens, manuscript paper, etc. also free US shipping over 25 dollars! the doujinshi size manuscript paper is A4 size (it trims down to B5)
deleter mangashop - sells manuscript paper, pens, screentone, etc. shipping is pretty expensive, however.
DaVinci Artist Supply - this particular davinci tends to carry screentones and doujinshi size manuscript paper, probably because they are so close to SVA
137 East 23rd Street New York NY 10010 Ph: 212 982-8607
clip studio paint - sai and mangastudio in one package. relatively cheap, also. carries a lot of screentones within the program and allows you to put down trim lines, text, etc. the cheaper version doesn’t allow you to organize your pages together in one big story, but shouldn’t really matter unless you want to mass export your files. UI is very similar to SAI when in illustration mode. I noticed that there was little to no learning curve when I first picked it up from using photoshop, SAI, and manga studio. overall a great drawing program and is great for drawing comics as well!
manga studio - a little hard to use but very versatile for comic drawing. I personally like drawing in clip studio more, but manga studio is still very good at what it does. it’s pretty hard to create illustrations with this software, but it’s more dedicated to comics (personally I use it to draw comics even though I have clip studio)
photoshop - if you really want to torture yourself. Not originally a drawing program, but has so so so many features. you can create your own guides which is a plus if you don’t want to use templates (clip studio doesn’t really allow for this, manga studio does but it’s a little confusing)
how to make doujinshi [JPN] - very useful site! google translate is ok here… mostly. even if you don’t speak japanese, you should be able to grasp the basic idea.
Understanding Comics by Scott Mccloud - this book was given to me as basically the bible of comics. you can judge it for yourself, but I think it was a very good read, even if you don’t plan on drawing comics. It’s less about the technicalities of drawing comics and more about understanding comic based storytelling. It is also a comic book itself, interestingly.
wally wood’s 22 panels that always work - I’m always looking at this when I draw comics!!!! it’s great when I wrote a long bit of dialogue and realized I don’t know where to put anyone because I’m a dang idiot!!!!!!!
hajimete no doujinshi [JPN] - google translate sort of fails here, so this is better if you have at least a little knowledge of japanese/japanese doujin terms (for example the japanese term for trim lines translates to “dragonfly”)
doujinpress - print quality was not great a year ago, but they are currently in the process of increasing their print quality. Staff are very helpful and kind. long loooong turnaround (6 weeks). they offer perfect bound. reasonably priced. not a lot of cover stock options, but I hear that will possibly change soon… also prints R18 material (!!)
smartpress - lots of cover options, paper options, etc! billies printed with them and quality looked good (I haven’t printed with them personally). reasonably priced and offers custom sizing. default turnaround time is 3 days (!!)
this is an incomplete list. Please add more if you think it belongs on here. Thanks!
