If he's a bit upset, he might press harder with the pen or if he feels sick, maybe he presses much lighter. For example, you would need an example of this person's signature using all kinds of different pens, and all kind of different surfaces underneath the paper, and all kinds of different paper. If the owner of the original signature uses a different kind of pen, the patterns produced will be much different. This will be a little less work than the other topic, but still a lot of work.įor the idea of forgery though, I'm not sure this level of detail can really be used for such a purpose.

If you want to duplicate that signature precisely, you would have to find a way to apply the precise pattern at the precise place in the.design (pen stroke). But if you look at your original image of a signature (zoomed in), you can see that there are different patterns in different areas of the pen stroke. However, calligraphic tool is not good for thickness at all, because it has a constant angle, which resembles the calligraphic pen, but changes in thickness because of pen pressure can be in any direction.Īs an alternative, I am thinking, what if we can a real texture of pen drawing on paper, then playing with it in Inkscape The chalk and sponge filter gives good effects, but its needs careful tweak to achieve something natural. (or simpler filters/distort/roughen click live preview and tweak te settings) Turbulence effect : to change the base frequency to change the 'frequency' of bumps/spikesĭisplacement map : to change the scale to change the distance of bumps/spikes from the center of your line In the filter dialog click chalk and sponge go to the

If you don't like the holes then start with the chalk and sponge filter (Filters/distort/chalk and sponge)Īnd go into the filter editor (Filters/filter editor) to tweak the settings I don't agree when you say the middle of line is always solid (it's true in your new image much less in the old one) V1nce wrote:For thickness control use instead of
