| A printer will usually leave a dot pattern to reproduce shapes, with a resolution fine enough that everything will be sharply defined. The blackness of a laser printer is a bit less qualitative than ink, because it's shinier from a large variety of viewing angles. Here if you zoom it a bit, you can see a very slight wobble in the pen tracks because it catches a bit of the paper's grain, and depositing ink, the paper "drinks" the ink which fattens the lines a tiny bit. This is more noticeable on the drawings with a lot of pen lifts/drops, where both the lift and the drop leave a dot a bit larger than the line between them. The one with gradients made with lines closer and closer is especially eye-catching to me because all of those imperfections adding to produce this "worn-out" look in the darkest parts of the gradients. Some paths overlap a bit and if you look very closely there are more than one nuance of black because of this - in some other places, the lift/drop are close enough that a bit of ink seems to travel by capillarity between the lift and the drop, resulting in two touching lines that were separated in the program.. The ones having a lot of circles show other imperfections, with a bit of ovalization in the circles, and the paths generated to fill the circles with black missing a few parts.. What I like a lot is that the result shows all of those little details that accumulate and produce this imperfect look, without needing to simulate it in Photoshop or another software if you were to print it with a regular printer. |
I think you're misattributing things. Plotters use stepper motors and so have a minimum distance they can move along each axis. Due to this, they don't produce perfect lines at an angle and do introduce similar artifacts to what you'd see on a screen.
