Jacquard Card File
Jacquard card — the weave design as loom-ready needle data.
A jacquard card is the control data that tells a jacquard loom which warp ends to raise on every pick, encoding a woven design thread by thread. Historically punched cards, today it is a digital file matched to the loom’s needle count and controller. It is the file a woven motif — brocade, damask, a woven saree — ultimately becomes.
How PatternAI writes a Jacquard Card file
PatternAI’s weave technique composes the design and writes the jacquard control data to the loom’s needle grid — the design mapped exactly to warp and weft, not an image. The file is matched to the needle count and verified, so the woven result is the approved design.
Machines that read Jacquard Card

Native file vs auto-converter
A converter traces a picture into a Jacquard Card; the result usually fights the machine — poor registration, wrong density or an outline that won’t run. PatternAI’s weave technique instead writes the Jacquard Card natively from a design built on a real grammar, and validates it against the format before it ships — so the file is one your machine can actually run.
Frequently asked questions
- Is the card matched to my loom’s needle count?
- Yes — the design is mapped to the loom’s needle grid, so the card matches the machine.
- Can it do brocade or damask?
- Yes — woven motifs like brocade and damask are composed and written to the jacquard control data.
- Is it the exact approved design?
- Yes — the design maps thread by thread and is verified before it ships.
Turn a design into a real Jacquard Card file
PatternAI turns a prompt, your artwork, or a live trend into a production-ready design and writes the exact Jacquard Card your machine runs — verified before it ships.
