	Pen plotters expose this friction: they are machines, and so we expect them to possess the machine's perfect seamlessness. Yet they do not. They are canonically machinal, yet they are flawed. Their works are made with a careful and hand-made quality, while being explicitly produced by a machine.

	I am passionate about animation, and a layperson. A tradition of hand-illustrated animations is ~~practices~~ by a select few. These projects tend to be impressive. They are also inaccessible to many to make: they tend to require a lot of labour, a lot of skill and, hence, a lot of funds. I don't have funds, and my skills are questionable. But I do have labour to dedicate, and a passion for plotting.		I am passionate about animation, and a layperson. A tradition of hand-illustrated animations is practiced by a select few.

			Some ambitions:

			Some questions:
			* Keep it digital, or build a mutoscope?

	...		At first, I had planned to physically cut the frames and make a flipbook out of them. After plotting, I decided not to because (1) alignment imperfections made the frames bleed into each other, and (2) I quite liked the sight of all frames together. So for this test, I went with a digital animation. This went as follows:

			# I made a scan using the WdKA's office printers.
			# I opened the PDF scan on my machine.
			# I opened [https://www.getpaint.net/ paint.net].
			# For each frame, I...
			## created a new paint.net layer with 50% opacity,
			## took a screenshot from the PDF,
			## pasted it into the new paint.net layer,
			## carefully aligned it with the previous frame underneath,
			## set the new layer's opacity to 100%,
			## and saved the new layer seperately.

	...		After our preparations, plotting should go smoothly! Instruction for plotting through Inkscape have been documented [[User:Thijshijsijsjss/Pen_Plotting_Panache/Plothatching_Workflow#Plotting_through_Inkscape\|here]]. Some notes:
			* I plotted with the Template layer visible, so that there would be clear lines to cut or align the frames.
			* For no reason in partcicular, I plotted Red first and then Blue.
			* The red and blue layer both took about 50 minutes to plot.
			* The SVG paths were amazingly nice and quite efficient. The Inkscape HPGL conversion follows the paths faithfully, so this is quite important.
