By "weight", I assume you mean file size?

Well, if it's black and white, make sure it's a greyscale image... no point in holding information for RGB if you don't need it, and that can bring the file size down by as much as 50%. Other than that, I just save it a .jpeg through Photoshop. There's an image quality slider that can save you a bit of memory in exchange for a slightly shittier image, but unless I'm trying to come in under a certain size for some reason, I never bring the slider down below 8 (and rarely below 10, anymore).

And of course, smaller images have smaller file sizes... unless you're making a wallpaper, it's rare that you should need an image for the internet larger than 1000 pixels wide (and that's pretty big on most monitors... I think the average resolution for most folks by now is 1024x786, but many people, including myself, are set at 1280x1024).

In addition to .jpeg, I think a lot of people are using the .png file format, but I'm not familiar with its specifics. I think .pngs may be smaller, though.

BTW, the .jpeg format is only for web display.

For print, the preferred format is TIFF, a lossless compression type that make huge images into really small files for storage, espescially if you use the LZW compression. Photoshop can save as a .tiff, and the format is universally recognized.

But B&W image should always be in Greyscale, either way.

It's always, ALWAYS best to draw at least 50% or larger than your final print.

Everything looks better when you shrink it a bit.

This is why comics are drawn at 10x15 but printed at about half that size. Illustrations are often done this way as well, and it's absolutely essential when you work digitally... print res is 300dpi but screen res is 72dpi, so what looks tight on screen often prints small, or poorly.

General rule of thumb: draw it twice as big as you plan to print it. Hard to go wrong that way, in my experience.

For that matter, concerning resolution:

Screen is 72dpi.
Print is 300dpi.
send files to the client for print at 400, so he can mess about with the size if he needs to.
I scan at 600, when working in ink. Convert that to a Bitmap using a 50-50 threshold, then back to Greyscale. This makes every line solid, pure digital black, and when you shrink it down to 400dpi any jaggies from the aliased Bitmap disappear.

Hey those are some helpful tips, maybe that's the reason why my hand inks look so smooth on paper but look like crap when I upload them on dA. Thanks for taking the time to provide this! I'm copying and pasting it into my folder of tutorials on my HD.
