wrong, on purpose

A generator you already have

Most shops solve "we need artwork" one of four ways now: buy stock photos everyone else already bought, pay an illustrator, stare at a blank canvas until inspiration shows up (it doesn't), or prompt an AI image generator and hope it doesn't look like every other AI image made this week. There's a fifth way sitting in the free tools already, and it's simpler, faster and more fun than any of them: throw a photo at the halftone tool, drag every slider somewhere stupid, and see what falls out. Most of it is garbage. Some of it is a genuinely good one- or two-colour print. Garbage-to-good is the only ratio that matters here, because the garbage gets deleted and nobody ever has to know about it.

You don't need Photoshop skill, an eye for illustration, or a plan. You need a photo and the patience to drag a slider back and forth like an idiot until something clicks.

Coarseness: from crisp to abstract

Coarseness is cell size, in pixels. Small, and the image barely changes — still recognisably a photo, just made of dots. Crank it up and the tool starts eating whole features for breakfast: an eye, a fold of fabric, somebody's entire face, swallowed into one grey blob. Nothing is technically "blurred" — there's no blur filter in here, it's just resampling into fewer, bigger decisions about where ink goes — but it looks like blur, reads like blur, and for our purposes is blur. Nobody's checking your math.

That range between "still a photo" and "no longer a photo" is where most usable artwork lives. Drag it slowly and watch for the moment a face stops being a face and starts being a shape — that's usually the frame worth keeping.

Strength and effect: carving out contours

Strength decides how much of the original photo survives next to the pattern. At 100% there's no mercy — every pixel is fully in or fully out, and the result looks like it was cut out of paper with scissors, not photographed. Drop the strength and some of the original tone leaks back in, softening the edge between "graphic" and "photo." Pair 100% strength with line screen or photocopy instead of a round dot and you get the fastest route from "photo of your cousin's dog" to "poster that looks like it belongs on a wall in a gallery that only sells to people in black turtlenecks."

Tone pushes the whole image lighter or darker before any of that happens, which decides which bits survive the massacre. Push it down first and only the darkest shapes make the cut — a stark, bold silhouette. Push it up and you keep almost everything, for a busier, messier result. There is no correct answer here. There's just the one you like.

Four effects, four different materials

Same photo, four completely different pieces of artwork, and none of it took longer than a slider drag.

Combine two effects and let them fight

Once you've got a favourite, there's a Combine switch next to the tiles that changes the whole game: instead of picking one pattern, you pick two or more and choose how they interact.

OR just overlaps them — denser, busier, everything either pattern would have inked on its own. AND keeps only the spots both patterns agree on — sparser, finer, oddly delicate for something built out of two aggressive patterns. XOR is the one worth your time: it keeps only where the two patterns disagree, which means two regular grids fighting each other produce exactly the kind of interference pattern every printing tutorial warns you never to make by accident. Here you're making it on purpose, and it looks fantastic.

Halftone plus line screen on XOR gives you a fine, shimmering moiré weave that no single effect can produce. Stipple plus photocopy on AND gives you a sparse, gritty texture that looks like it survived several bad photocopiers in a row. None of these combinations are things you'd think to ask for — they're things you find by clicking the wrong two tiles together and liking what happens.

Why trial and error actually works here

The whole method only works because being wrong here costs nothing. No upload, no job spent, no consequence — a bad combination costs you exactly the three seconds it takes to notice it's bad and change it. So don't plan the result. Run the same photo through six or eight combinations that make no sense together, keep the two that don't look like a mistake, and delete the rest without a moment of guilt. Trial and error only works when error is free, and here it's free.

Download a result you like, then drop that PNG straight back in as a new source image and run it through again with a different effect. Distortion compounds. Two passes deep you're somewhere a single pass could never have found on its own — which is either a happy accident or evidence the tool has better taste than you. Either way, keep it.

From artwork to a printable film

Once something's actually worth printing, treat it like any other artwork: bring it into PrintFilmReady and let the real separation tool do the actual screening for your mesh. Don't run it through a halftone twice — the halftone effect tool makes the picture, PrintFilmReady makes the film, and stacking one screen on top of another is exactly how you get moiré and a very confused customer. While you're playing around, keep the coarseness here obviously coarser than your press halftone, so you're not building the problem in before you've even separated the file.
