Pre-press model · Trained on 3,000 real works

Lupa v1.

Lupa · the printer’s loupe. The lens held to a film to check every dot before it goes to press.

Our pre-press model. It reads a design the way a printer does before it goes to press: what will hold, what will drop out, what to fix, and what to leave alone.

What it does

  • Reads the fileThe artwork and the print files made from it, colour by colour, at the size it will print.
  • Judges the pressLines too thin to hold, specks a screen can’t keep, colours too close to separate, halos on dark garments, files too soft for their size.
  • Leaves the work aloneIt tells deliberate texture from noise. Grit, grain and distress are part of the work, and they stay.
  • Routes the fixEach decision goes to the right tool in our print engine, where the fix is exact and repeatable. A person signs it off.

  1. BackgroundRemove it. Only the art goes to print.
  2. Worn texture in the titleKeep it. It is part of the work, not damage.
  3. Fine lines in the frameCheck they are thick enough to hold ink at print size.
  4. Soft glow in the lightningPrint it as halftone dots, so the fade stays smooth.
  5. ResolutionEnlarged to print size, low-resolution artwork loses definition, so Lupa rebuilds it at 4K. It adds pixels, never design: nothing is drawn, moved or changed.
    The face enlarged to print size from the file as sent: soft, losing definition.

    The same face rebuilt at 4K: sharp, with the same shapes.

How a file moves

  1. A design comes in. Lupa reads its colours, judges which inks will look best on the garment, and picks the spot colours, each matched to a Pantone colour.Lupa v1
  2. The engine makes the print files. A screen PSD with one film for each ink, and a DTG/DTF PSD for direct-to-garment and film printers. It checks every one, and draws a proof of how it will print on the garment.Print engine
  3. Lupa reads the films. It judges what will fail on the press and proposes what to do, region by region.Lupa v1
  4. A designer decides. Accept, change, reject, or leave it as it is. Anything missed is added by hand.Our Design team
  5. The engine makes the fix. Exact operations, never a redraw. The artist’s art stays theirs.Print engine
  6. It goes to press. And what happens there teaches the next decision.The press floor

How it learns

  • From our own workThe decisions our designers and printers make on our own archive of past print work: what they accept, change, reject or leave alone, and why.
  • From years on the pressYears of screen printing for bands, tattoo artists and illustrators in Europe and South America, and the work we printed along the way.
  • People decideThe model proposes. Every label it learns from is a person’s decision.

Colour, from screen to garment

  • Plans the separationLupa plans each separation the way a printer does: which colours become inks, which to merge, which to print as halftones, and where a screen can be saved without anyone seeing the difference.
  • Matches Pantone coloursEvery colour in the design is matched to a PANTONE® colour, and every ink is mixed in our studio to its PANTONE® formula and checked against the approved proof. PANTONE® and other Pantone trademarks are the property of Pantone LLC.
  • Separates realistic artWith our print engine, it separates photorealistic art, like a lifelike face or animal, into simulated-process screens: halftones that rebuild the full image in a few inks on fabric.
  • Shows the print firstBefore anything is printed, the artist sees a proof of the design on the garment, drawn from the real films and inks.
  • Keeps the artist’s coloursA band’s red or a brand’s colour is marked as theirs, and never merged away.

What it never does

  • Make artIt never draws, redraws or generates artwork. It decides what to fix and where.
  • Copy a styleIt is never trained to generate images or imitate an artist.
  • Use members’ filesIt learns from our own archive and print shops in our training programme, never from members’ artwork or what they do in the Studio. Read how
