So here’s a real quick thing since I get often get asked about tones. Obviously this is just my horrible way of doing it. I usually keep my files at 400dpi.
1. For this to work, do your shading on a 100% opacity layer over your lines, set to multiply. I pick a fairly light gray tone most of the time since the next steps will darken the image a bit. [Sometimes people do their tones by drawing with black on a layer and then knocking down the layer opacity — this way won’t work here.]
2. I used the lasso tool here and darkened some of the tones and added gradients, just on the same layer.
3. You can add a tiny bit of noise to this gray layer to give it a more textured look.
[This step is mostly for the tones to look better on a screen — it can print too dark if you do this without testing, but it can also work out nicely sometimes. For example I don’t add noise for stuff like OCB pages and go directly to the next step.]
4. Duplicate your noise layer (if you’re using the noise step), then use your Color Halftone filter on the new layer. You can play with the settings, but here’s what I generally use for screens. [If you want, you could duplicate your flat-graytones before adding the noise and then halftone that on top of your noise layer — I just find this way adds more grain to the overall result.]
5. Merge the two layers (ctrl+E) [not necessary if you’re just doing halftones and no noise, again] and use the eraser tool to rub out any unwanted screentone like you’d do with an X-acto knife. Highlight stuff, add speedlines, you’re the king of the world go crazy nobody can stop you now wow
