In this section, Hume first argues that our ideas and impressions of space and time aren't infinitely divisible, one of the arguments is that the capacity of the mind is limited therefore it cannot perceive an object with an infinite number of parts, so it cannot be infinitely divisible, the same for impressions and the proof is that if someone moves a piece of paper with a spot of ink on it until it disappears, the moment before it does, it represents the smallest indivisible impression.

Pen manufacturers using a proprietary cartridge ( which in almost all cases are the more expensive ones like the ones mentioned above ), tend to discourage the use of cheaper internationally " recognised " short / long cartridges or adaptations thereof due to their variance in ink quality in the cartridges which may not offer as much performance / or be of lesser quality than the manufacturer of the pen ; ink that has been designed specifically for the pen.

In the patented Electroetch system, invented by Marion and Omri Behr, in contrast to certain nontoxic etching methods, an etched plate can be reworked as often as the artist desires The system uses voltages below 2 volts which exposes the uneven metal crystals in the etched areas resulting in superior ink retention and printed image appearance of quality equivalent to traditional acid methods.

Copper is a traditional metal, and is still preferred, for etching, as it bites evenly, holds texture well, and does not distort the colour of the ink when wiped.

Pens may be obtained from various stationery sources-from the traditional " nib " pens dipped in ink, to calligraphy pens that have cartridges built-in, avoiding the need to have to continually dip them into inkwells.
