Spend the Black

A dense black-and-white sticker illustration — a creature fused with machinery — with solid black treated as a material you place, not a colour you run out of. Five fields.

Two runs of the same template. 7.6 percent by the same measurement, and the separation test is clearer here than in the first run: the shell reads as a separate object from the legs because the gap between them is filled solid rather than hatched. Both runs land in the same place - the law moves the number off zero and makes the drawing structural, and neither run spends as much black as the template asks. If you want the full quarter, name large areas in the field and expect to argue for them.

Measured rather than eyeballed. Eroding the black mask so hairlines drop out and only real masses survive, the reference run scores 0.0 percent - not one solid black area in the entire drawing, which is exactly the fault. This run scores 9.4 percent: the gauge faces, the cup interior, the portafilter handle and the gaps between the boiler and the mantle are all filled, and the boiler now separates from the body because of it. Short of the quarter the template asks for - the small named areas got blacked and the large ones, the undersides and arm shadow sides, stayed stipple.

You fill in 5 fields — the braced lines at the top. Everything below them is fixed.

  1. 1The creature, and the machine fused into it
  2. 2What it is doing, and what it holds
  3. 3Where the solid blacks sit
  4. 4The parts bolted on
  5. 5What is underneath

Spend the Black

Produce ONE image, 2:3 portrait: a dense black-and-white creature- machine illustration on plain white. Follow every line. Replace only the FIELDS block; everything after it is fixed.

First — do you have the fields?

If any field below still has braces around it, stop and ask. Put all the questions in one short message, and show the example under each one so they can see the shape of a useful answer. Wait for the replies, then draw. Never fill a brace yourself: a value you invented is a value nobody asked for, and it will look exactly as considered as the ones they did give you.

Ask in whatever language they are writing to you in. Translate the questions and the examples; do not make someone read English to tell you what they want.

The examples are only examples. If someone answers a question, use their answer; never fall back to the example because you prefer it.

If the fields are already filled in, ignore this and carry on.

Fields — replace these five lines only

  • The creature, and the machine fused into it: {an animal — a machine}
  • What it is doing, and what it holds: {an action, and the objects}
  • Where the solid blacks sit: {four or five places on the subject}
  • The parts bolted on: {fittings and hardware}
  • What is underneath: {what it stands in, rises from, or sits on}

The black law

"Black and white" describes two things, and only one of them ever turns up. Asked for high contrast, this style reliably returns a drawing made entirely of outline and stipple — no solid area anywhere, every part at one hairline weight, the whole thing reading as a single field of pale grey.

Roughly a quarter of the drawn area is solid black. Not hatched, not stippled — filled.

The fields say where it goes, and it goes on structure, not decoration:

  • undersides — beneath the body, beneath every limb, beneath every shelf and plate
  • insides — the inside of a cup, a mouth, a pipe, an opening
  • shadow sides — the far side of every rounded form, following one consistent light
  • the gaps between parts — where a bolted-on component meets the body, the gap is filled black

A reference run of this style drew a superb mechanical octopus with not one solid black mark in it. Every gauge, sucker, rivet and pipe was rendered in the same fine line, and the result was a colouring page: no weight, no depth, and no way to tell where the animal ended and the machine began.

The separation test

Black is what separates the creature from what is bolted to it.

Where a machine part sits on the body, do not distinguish them by drawing more detail on one. Fill the gap between them solid. If two things touch and you cannot tell which is in front, the black is missing.

Line weights

Exactly three, doing three jobs:

  • Heavy — the outer contour of the whole subject, one continuous weight, holding the silhouette.
  • Medium — the edge of every distinct part.
  • Fine — texture only: stipple, hatch, grain, suckers, knurling.

Fine lines never describe an edge, and heavy lines never describe texture.

Density

  • Detail is dense but organised: every area belongs to a part, and every part has a boundary you could trace.
  • Texture varies by material — stipple for organic surfaces, straight hatch for metal, dots for grip, concentric lines for turned parts.
  • Leave a few rest areas — plain white on the largest forms — so the eye can tell the detail from the shape.

Ground and finish

  • Plain white, edge to edge. No border, no frame, no cast shadow, no panel behind the subject.
  • The subject sits alone, centred, drawn to be cut out.
  • No colour, no grey ink, no gradient, no texture on the ground.
  • No text anywhere.

Never

  • ✕ a drawing with no solid black in it
  • ✕ black used only for a keyline or an outline
  • ✕ one line weight throughout
  • ✕ fine lines used to describe an edge
  • ✕ two touching parts separated by detail rather than by black
  • ✕ grey, colour, gradients or airbrushing
  • ✕ a border, background panel or drop shadow
  • ✕ text, labels or logos

The result

A drawing with weight in it: a heavy silhouette you can read across a room, solid black doing the structural work underneath and between, and fine detail sitting where there is room for it.

The whole template, in one piece. The steps below are the entire workflow.

How to use it

  1. Copy the whole template with the button above.
  2. Replace the five FIELDS lines. Name the black areas as places on the subject — undersides, insides, shadow sides — rather than as an amount.
  3. Paste it into any image-capable agent or model, in one message. One run returns the illustration.
  4. Squint at it before shipping. If it goes uniformly grey, no black was spent and the picture has no weight.

What you swap

The creature, and the machine fused into it
an octopus crossed with an espresso machine — brass boiler head, gauges set into the mantle
What it is doing, and what it holds
pulling a shot and pouring it — a kettle in one arm, a tamper in another, a cup and saucer held out front, a portafilter locked into a third
Where the solid blacks sit
the whole underside of the mantle · the shadow side of every arm · the inside of the cup · the gauge faces · the gaps between the machine parts on the body
The parts bolted on
pressure gauges, a pipe coil, riveted plates, a small aerial, a power lead trailing off
What is underneath
a bank of steam clouds with jets driving down into it

Before it runs

  • A creature with a heavy mass to it. Black needs somewhere to sit; a spindly subject leaves nowhere to put it.
  • A willingness to lose detail. The blacks will cover things you drew, and that is the trade that makes the drawing read.
  • Parts that are genuinely bolted on, not merely nearby. Fusion is what the black then has to separate.

When to reach for it

Merch, stickers, band and skate graphics, mascot art with grease under its fingernails. Templates in this style ask for strong black-and-white contrast and return a colouring-book page: every part drawn at one hairline weight, nothing solid anywhere, and no way to tell the creature from the machine bolted to it.

What changes

  • One dense creature-machine illustration on plain white, drawn to be cut out.
  • Solid black placed deliberately — a stated share of the image — so the drawing has weight rather than only detail.
  • Three line weights doing three jobs: a heavy contour that holds the silhouette, medium for parts, fine for texture.
  • The creature readable against its own machinery, because black separates the masses instead of line density hiding them.
  • Detail that survives being printed small, since the blacks carry the shape when the hairlines disappear.
