A buyer sends us a tech pack for a 120 × 120 cm swaddle in a colour that is not on any stock card, and asks for 150 pieces. Two weeks later they have a quote for 600 pieces, or a quote for 150 at a unit price that makes no sense. Both outcomes feel like the factory is negotiating.
Neither is. The number is not a sales tactic. It is the dyeing machine.
Muslin reaches your colour by two completely different routes, and their minimums differ by a factor of six hundred. Knowing which route your product is on tells you, before you send a single email, whether a small first order is possible — and what it costs you to insist on the wrong one.
Three routes, three constraints
Buyers talk about “custom colour” as one thing. In production it is three.
| Route | What it actually is | Minimum | The constraint |
|---|---|---|---|
| Stock colour | Fabric already dyed to a colour on our card | 500 pcs per colour | The fabric exists; the floor is production setup |
| Custom dyeing | Your colour, dyed to an approved lab dip | 600 pcs per colour, quoted on a 120 × 120 cm swaddle | The dye bath |
| Digital print | Your artwork printed directly onto the fabric | 1 piece | Nothing but the file |
The third row surprises people. There is no minimum because there is no bath and no screen — the file goes to the printer and the printer prints what you send. If your product is a print rather than a solid colour, the conversation about minimums disappears. If it is a solid colour, it does not.
Why a dye bath has a floor
Cotton gauze is dyed in rope form: the fabric is fed into a machine as a continuous rope and circulated through a heated dye liquor. Two things set the minimum load.
The machine has a working range. Below a certain weight of fabric the rope does not run evenly — it tangles, and the liquor-to-goods ratio drifts away from what the recipe was written for. The result is not “a bit lighter”. It is uneven: shade variation across the piece, and a selvedge that reads differently from the centre. A batch that small is not a cheap batch, it is a reject batch.
The per-colour costs are fixed. A lab dip has to be matched and approved. The recipe has to be written. The machine has to be cleaned down between colours, and the first metres of the next colour are lost to flushing. None of that scales with quantity. Across 600 pieces it is a few cents a piece; across 120 it is most of your unit cost.
So when we quote 600 as the floor for a custom colour, we are not asking you to buy more. We are telling you where the machine starts working properly.
600 is per colour, quoted on a 120 × 120 cm swaddle. That basis matters. A 150 × 200 cm blanket consumes roughly twice the fabric per piece, so 600 of it is a much larger batch than 600 swaddles. The number is a proxy for fabric weight, not a count of pieces.
What the 600 actually buys you
One lab dip, approved before any production fabric is dyed. One dye lot — every piece is the same shade because it came out of the same bath; split that volume into four small batches and you have four lots that will not match under retail lighting. And a reorder that matches, because we keep the dye lot record, so your second order can be matched to the first.
Colour variation is one of the four defect types we track on every order, alongside open overlock seams, snags and oil spots. Our target is 2–3 defective pieces per 100. On a solid-colour product, shade consistency hurts most, because it is the only defect a consumer can see without examining a seam.
Why digital print starts at one piece
Digital print removes both constraints at once. No bath to fill, no screen to burn per colour, so the setup cost lives almost entirely in the file: the repeat, the colour separation, the profile for that fabric. Once that is done, piece one and piece one thousand cost roughly the same to set up — which is why a single piece is possible, and why a 150-piece first order in your own artwork is a normal order rather than a favour.
Two honest limits, because they matter for costing.
Print is more expensive per unit at volume. Digital print does not get dramatically cheaper as quantity climbs the way dyeing does. A two-colour repeat that will run at 5,000 pieces a season belongs on dyed or screen-printed fabric, and you should plan that transition deliberately rather than discover it.
Print sits on the surface. On 80–130 GSM double-layer gauze, a print changes the hand slightly compared with a dyed ground, and very deep saturated darks are harder to hold on a thin, open weave than mid-tones are. If your artwork depends on a near-black field, ask for a strike-off on the actual fabric — not a digital proof on paper.
The mistake that costs a season
The expensive error is not picking the wrong route. It is switching routes halfway and assuming the colour comes with you. A print is ink sitting on the surface; a dye is a chemical bond inside the fibre. They can be matched closely, and a good lab will get them close, but they are not the same physical thing and will not age identically through fifty washes.
So “print the first run small, dye it once volume justifies it” is a sound plan — but approve both colours at the same time, side by side, in the same light. Buyers who approve a strike-off in March and move to dyeing in September usually find the shift in October, with stock already on a boat.
The reverse happens too: if a print has to sit next to a dyed solid on the same shelf, say so at the artwork stage, and we will print the ground to the dyed reference rather than to the Pantone alone.
How to route your first order
If you are testing artwork, print and start small — a few hundred pieces tells you whether the pattern sells. If you want a solid colour in a shade we already carry, that is the stock card at 500 pieces per colour, and the cheapest route per unit because the dyeing has already happened. If the colour is yours and you expect to reorder it, it is custom dyeing at 600; and if 600 is more than your first season needs, the honest options are fewer colours rather than fewer pieces, or launching the solid as a print and converting later.
That last one is where most first orders go wrong, and it is usually arithmetic rather than budget:
A buyer asks for 1,200 pieces across three colours. That is not 1,200 pieces. It is three colours at 400 each, and 400 is below the floor for every one of them. The order that clears is 1,800 pieces, or two colours at 600, or one colour at 600 plus a print.
Ask for the quote per colour, not per order. Almost every “your minimum is too high” email we receive turns out to be this.
What to put in the RFQ
- Quantity per colour, not total, and the size each colour applies to.
- Vector artwork and a Pantone reference if it is a print. A JPEG cannot be colour-separated.
- GSM and layer count. We work in 80–130 GSM measured as double-layer finished weight, not single-layer greige weight. The two are not comparable, and mixing them up changes the quote.
- Finished size, and whether it is cut or washed. Cotton gauze shrinks; a size stated before washing is not the size your customer receives.
- Market and test requirements. For the US, CPSIA and the applicable 16 CFR rules, with a CPC covering the finished product — reflecting the printed surface, not a greige swatch, if the product is printed.
Production runs 25–30 days from deposit and artwork approval. Sampling on stock fabric is 1–3 days to make plus about a week in courier. Neither clock starts until the colour question is settled, which is why this decision belongs at the front of a project rather than the middle.
Where we say no
We turn down custom colours below 600 pieces — not because we would rather sell more, but because the batch we would produce is the batch that comes out uneven, and we would end up remaking it. We also turn down orders that cannot fit 25–30 days: compressing a schedule on gauze means skipping the wash or the relaxed drying, and the shrinkage then shows up at your customer instead of at our inspection table.
If your quantity is below the floor and your colour is fixed, the useful conversation is not about the minimum — it is about which route gets you closest to that colour at a quantity that makes sense, and that is usually a print.
If you are weighing a print against a dye for an upcoming collection, send the artwork, the colour reference and your quantity per colour, and we will tell you which route we would run and what it changes about your cost and timeline. Start here.
