Very sorry I have been away for so long but I’ve been working on things and have found an abandonded baby rat which I am taking care of and nursing. I’m a sucker for baby animals. Anyway I thought that since CamStudio and windows movie maker hate me so much that I could screen cap how to screentone in gimp.
When you have finished and inked your work change the image mode to Greyscale. This step is very important! It’s so the tones will work properly later. The above image is one of my inked works.
Next colour in grey tones in a layer underneath the lineart layer and label it tones. Colour where you’d liked shadows to be. Add patterns to it if you like or pattern stamp in the background. Keep it on the tone layer. If you have to use a sperate layer for some parts, remember to merge them at the end. Later if you want tones of differnt sizes just repeat the process on a new layer.
When you’re done with your lighting and shading and are ready to tone go to, Filter >> Distort >> Newsprint. (Just a little note, using gradient tool will give you gradient tones which is what I did to the character to the left as an example.)
This control panel type of thing (I forget the term) will pop up. Play with Input and cell size to get the tones you want. You will have to go by the preview box. If the preview is blank don’t worry, click hold and drag in the preview area until you find your coloured area which will show it as tones. Leave the angel at 45 for now. When you have the size you think it right, click ok and you will have digital screentones. (also you can choose more than just dots, you can have lines or diamonds, it’s up to you with what you use. You can do this by looking through the spot function.)
It’s that simple. After you get use to it and judging the dot sizes, play around with the angel and dots to get other effects. When in a small view the tones will look distorted so be sure to check them with the image zoomed in at actual size or actual pixels. Also printing them out can often be the best test. You can do similar in photoshop. I’ll post a new post on how to do it in ps7. It’s almost the same process but slightly more complicated.
In GIMP it doesn’t seem to matter as much if you chose a paper size. The newsprint feature seems to be unaffected and works the same way in most resolutions. Photoshop on the other hand, if you choose to screentone in photoshop with the colour halftone feature then your image MUST be AT LEAST 300 resolution (or dpi). You can work from either 300, 600 or 1200 in any paper size eg A4, A5, A6, B4 etc. These are the main used resolutions or dpi for manga/comic’s and in order for colour halftone to work best you MUST have your image set to greyscale when you are ready to tone and you will find similar controls to what GIMP uses. Halftone doesn’t work as well so you’ll have to use the colour halftone filter in greyscale mode for the best results. I’ve found paper size B4 set to a resolution of 600 works quite well.
Next post I will give screen caps on how to do it along with a small repeat of the previous paragraph.
