How Custom Colors, Sizes and Packaging Work with Textile Factories

Consider a common scenario: a buyer sends a factory a photo of a throw in “dusty rose” and asks for several thousand pieces. The bulk arrives in three visibly different pinks. Nobody made an error, exactly — the buyer never specified which pink, the factory matched the photo as best it could, and photos lie about color. The entire dispute traces back to one missing step: an approved lab dip against a real color standard.

Customization is where textile factories earn their keep — and where vague instructions go to die. This guide walks through how custom colors, sizes, and packaging actually work: the ordered steps, the tolerances, and exactly what you must supply so the bulk matches the vision.

How does custom color work with a textile factory?

The process runs in a fixed order. First, you supply a color standard — almost always a Pantone TCX (cotton) reference for textiles, which the dyehouse can formulate against. The factory’s lab then produces lab dips: small dyed swatches, typically 2–4 variants bracketing your target shade. You review them under controlled lighting and approve one, sometimes requesting a second round if none hit the mark. The approved dip becomes the sealed reference for bulk dyeing.

Two details decide whether this works. Lighting: evaluate dips in a lightbox under D65 (artificial daylight), because the same swatch looks different under store fluorescents, warm LEDs, and daylight — a phenomenon called metamerism that causes a surprising share of color disputes. Tolerance: agree in writing what counts as acceptable bulk variation (commonly assessed against the grey scale for color change), because bulk dyeing thousands of throws will never match the dip molecule-for-molecule. The approved dip plus a written tolerance is the entire color contract.

Expect the lab dip cycle to take roughly a week per round including courier time — confirm the lab’s current schedule when you place the request — and budget for two rounds on difficult shades like deep navies, bright reds, and heathered greys. Faux fur colors deserve special care: the pile’s depth and direction shift the perceived color, so approve dips on the actual pile fabric, not on flat cloth.

How do custom sizes work?

Custom sizes sound simple — “make it bigger” — but they ripple through costing and production. Every size change alters the cutting marker (the layout that nests pattern pieces on the fabric roll), which changes fabric consumption per unit and therefore the unit price. A throw that grows from 130×170 cm to 150×200 cm doesn’t just use more fabric; it may break the marker efficiency the original price assumed.

The process: you supply finished measurements for each size in the range, the factory’s pattern team grades the spec sheet, and you approve a pre-production sample in the actual size before bulk cutting. Check the details that photos hide — corner finishing, hem width, fringe length — because these are set at the pattern stage and expensive to change later. For bedding sets, confirm that all pieces in the set (fitted sheet, flat sheet, pillowcases, duvet cover) are graded consistently; a “queen” that fits one retailer’s mattress spec may not fit another’s, so anchor sizes to your market’s standard, not the factory’s default.

How does custom packaging work?

Packaging is a separate production stream with its own timeline, and buyers who treat it as an afterthought discover this when the goods are ready but the boxes aren’t. The standard options: polybag with a printed insert card (the value default), belly band (a printed paper wrap — cheap, retail-friendly, common for throws), hangtag with barcode (needed for most retail receiving), and full gift box or window box (premium positioning, highest cost).

Quote packaging separately and confirm three things: dimensions (the box must fit the folded, compressed product — send the factory your folding spec or approve theirs), artwork (supply print-ready files; confirm proofs on the actual board stock, because colors shift on kraft vs. white), and barcodes/regulatory marks (UPC/EAN, care labels, and any market-required symbols must be correct before print runs). Packaging production commonly takes a few weeks after artwork approval — confirm the printer’s schedule and run it in parallel with bulk sewing, not after.

What must the buyer supply?

Factories execute specs; they don’t invent them. The complete buyer package for a custom program has four parts. First, color standards: Pantone TCX references for every colorway, plus the approved lab dip once issued. Second, a tech pack: finished measurements, construction details, stitching and finishing notes, and a bill of materials if trims matter. Third, artwork files for prints and packaging: vector files with fonts outlined, at the correct scale, with a color-separated proof for printed designs.

Fourth — and most skipped — the commercial terms that constrain the spec: target price, MOQ per colorway, and the market’s regulatory requirements (care labeling, fiber content declarations, chemical compliance — see our OEKO-TEX and REACH compliance guide for the EU chemical side). A tech pack without a target price gets engineered to the wrong cost; a color standard without an MOQ gets dyed in a lot size that ruins the economics. Supply all four and the factory can quote accurately the first time.

Ordered process: from idea to approved bulk

1. Brief: send Pantone TCX references, tech pack with measurements, artwork files, target price, and MOQ per colorway.
2. Lab dips: factory dyes swatches against your standard; you approve one under D65 lighting (allow roughly a week per round — confirm the schedule).
3. Strike-off / pre-production sample: for prints, approve the strike-off; for all products, approve a PPS in final materials, size, and packaging.
4. Bulk costing lock: confirm unit price against the approved spec — size, color count, and packaging are now fixed.
5. Bulk production: dyeing to the approved dip, cutting to the approved marker, sewing to the tech pack.
6. Packaging in parallel: print and convert packaging while bulk sews; confirm proofs before the print run.
7. Pre-shipment inspection: check bulk against the sealed lab dip, the PPS, and the spec sheet — not against memory. Our pre-shipment inspection guide covers how to structure that check.

Notice what the process protects: every approval creates a physical reference (dip, strike-off, PPS) that later inspections measure against. Disputes happen when references are verbal. Keep the chain of physical standards unbroken and customization becomes routine instead of risky.

Requesting a quote: specs to confirm

When you request a quotation for a custom program, confirm these items in writing so the quote is comparable across factories:

• Color: Pantone TCX references per colorway; lab dip rounds included in the price and the lab’s current turnaround
• Sizes: finished measurements per size; whether the quote assumes your graded spec sheet or theirs
• Packaging: exact packaging type, dieline/dimensions, artwork proof stage, and whether packaging is included or quoted separately
• Commercial: MOQ per colorway, unit price at your quantity, payment terms, and production lead time with its start condition
• QC: inspection standard and who inspects; acceptance criteria for color (grey scale grade) agreed before bulk

Frequently asked questions

What is a lab dip and why does it matter?

A lab dip is a small fabric swatch dyed by the factory’s laboratory to match your specified color, usually supplied in 2–4 shade variants. It matters because it converts a subjective color (“dusty rose”) into an objective physical standard. Once you approve one variant under standard lighting, it becomes the contractual reference for bulk dyeing — without it, color disputes have no referee.

Can I approve colors from photos?

No — not for anything you intend to sell. Phone screens and cameras shift color unpredictably with white balance, ambient light, and display calibration. Photos are fine for direction (“warmer than this”), but final approval must be on a physical swatch viewed under D65 standard lighting. Every experienced dyehouse will insist on this.

How many custom colors can I order per style?

As many as the economics support. Each colorway typically carries its own MOQ because dye lots have minimum quantities — commonly a few hundred to a few thousand units per color depending on the fabric. Spreading a small total order across many colors raises the per-unit cost and complicates QC, so most buyers consolidate to 3–6 colorways per style. Confirm the per-color MOQ on the quotation — it varies by fabric and dyehouse.

Does custom packaging delay my order?

It can, if sequenced poorly. Printed packaging commonly needs a few weeks after artwork approval, which fits comfortably inside a typical multi-week production window when run in parallel. Delays happen when artwork arrives late or proofs need rework — send packaging artwork with the initial tech pack, not after bulk starts.

What file format should artwork be supplied in?

Vector files (AI, EPS, or PDF with outlined fonts) at actual print scale, with colors specified as Pantone references where brand colors matter. Raster images should be at least 300 DPI at final size. Always request a physical or digital proof on the actual substrate before the print run — screen previews don’t show how ink behaves on kraft board or fabric.
