Once your patterns are digital, they have to get back onto fabric. There are two common
ways: print them on paper with a plotter, or shine them onto the cutting table with a
projector. They cost different amounts, fail in different ways, and suit very different
workshops.
How each one actually works
A plotter is a wide-format printer. It draws your pattern at 1:1 scale on
a roll of paper. You then cut the paper, pin it to fabric and cut around it — exactly the
traditional workflow, but with a perfect pattern every time.
A projector is mounted above the cutting table and projects the pattern
outline directly onto the fabric. You cut along the light. No paper is involved at all.
Side by side
The projector problem nobody mentions
A projector must be calibrated, and it must stay calibrated. The
image is a cone of light: if the unit shifts by even a few millimetres, or if the table is
nudged, every pattern it projects is now slightly wrong — and nothing on screen warns you.
Also, the projection is only accurate on a flat plane. Fabric on top of fabric raises the
surface. Cutting a thick stack under a projector introduces parallax error at the edges,
because the beam meets the top layer at an angle away from centre.
The daily calibration check
Project a 50cm × 50cm test square at the start of every shift and measure it with a tape.
Ten seconds. It catches drift before it costs you a garment.
The plotter problem nobody mentions
Consumables. Paper rolls and ink are a permanent line item, and at volume they add up faster
than most people budget for. Cheap paper also curls in humidity, which pulls your pattern
out of true after a day or two.
Plotters are also slower than they look. A full multi-size marker takes real minutes to
print, and if you are printing on demand behind a customer at the counter, that queue is felt.
Which one for which workshop
Buy a plotter if…
- You need physical patterns to hand to cutters, tailors or a second unit.
- Your cutting happens in more than one place.
- Your room has strong natural light you cannot control.
- You cut a lot of dark fabric.
- You want the pattern archived physically as well as digitally.
Buy a projector if…
- You cut single-ply on one fixed table.
- Volume is high and paper cost is a genuine irritation.
- You do a lot of custom sizes and want instant switching between them.
- You have a dedicated space where lighting can be controlled.
What we would actually do
For a boutique doing custom orders with frequent size changes and one cutting table, a
projector pays back quickly and removes the paper habit entirely.
For a unit that hands patterns to multiple tailors, or cuts across several rooms, a plotter
is the safer purchase — a paper pattern needs no calibration, no darkness and no explanation.
If the budget stretches, many units run both: plotter for production patterns that get
reused, projector for one-off custom sizes.
Before you decide
Neither device helps if your patterns are not yet clean and correctly scaled. Start with the
CAD roadmap. And if your bottleneck is the
cutting itself rather than the pattern output, read the
laser cutter guide before spending here.
