Flat-lay of 300gsm coral fleece throw swatches beside a sampling printer, shade bands, rub test cards, and QC tools on a cutting table

1. Start with the fibre, dye route, and pile structure

A 300gsm coral fleece throw is usually a brushed polyester pile fabric, often 100% polyester. Some mills offer blends, but the decoration path changes materially if the base is not polyester-rich. On a lofty pile, the print sits on a compressible surface, so sharp edges, small type, and tight halftones will spread or lose definition once the pile is disturbed by curing, washing, or packing.

Before discussing artwork, confirm three things in writing: fibre composition, base-dye route, and whether the mill has already run the exact decoration recipe on the exact bulk cloth. If the article is 100% polyester, true discharge printing is generally not the default route. Classic discharge chemistry is built for cellulosics; on polyester coral fleece, the practical choices are pigment, sublimation, transfer, or a specialty low-build effect that is not the same as true discharge. If a supplier says they can “discharge print” polyester coral fleece, ask them to define the mechanism, binder system, and post-cure wash result in the quote.

For sourcing, the buy is a substrate-print system, not an image file. If the base cloth changes from lot to lot, shade, nap angle, and pile density shift, and the graphic follows. A repeat order stays stable only if the buyer locks the fabric construction, base colour, decoration method, and wash route in the tech pack. For a cleaner comparison on colour built into the fibre, see solution-dyed polyester fleece.

2. What print routes can buy you, and what they cannot

If the fibre system is compatible, a low-build print route can reduce surface film compared with a heavy pigment print. The main benefit is softer hand after curing and less visible cracking on fold lines. On coral fleece, that matters because buyers usually want the blanket to feel plush after decoration, not coated.

The limitation is more important than the pitch. On polyester coral fleece, a true discharge effect is often unavailable or unstable unless the material was selected for that exact process. In practice, some mills use the term loosely for a low-build polyester print system, a special pretreatment, or a reduced-ink effect. Those are not interchangeable. Ask the supplier which process they are actually using, the cure temperature, the fabric pre-treatment, and whether the bulk base has been tested with the same recipe and lot combination.

Put the acceptance criteria in the PO. For colour fastness, specify ISO 105-C06 with the laundering method, specimen size, and a minimum grey scale result. For a promotional throw, a practical target is often grade 4 or better for colour change and staining, but the threshold should be set to the artwork and market. For rubbing, specify ISO 105-X12 dry and wet crocking, commonly targeting at least grade 3-4 dry and grade 3 wet for a soft-goods throw, with the method and specimen count stated. For appearance retention, use ISO 6330 wash cycles and ISO 12945-2 for pilling where the buyer needs wash durability. If the supplier cannot state the sample count, wash cycle, and pass/fail threshold, the test reference is too vague to enforce.

3. The five procurement routes buyers actually compare

1. Low-build print effect on an approved light base: Use only when the base fabric, dye system, and chemistry are already proven together. This gives the softest hand, but colour depth is limited and dark-brand reproduction is weak. Best for tonal logos, silhouettes, and gift throws where touch matters more than graphic impact.

2. Direct pigment print on coral fleece: This is the most common fallback. It is easier to source and easier to repeat, but the binder adds stiffness and can flatten the pile. Expect more visible print film on solid areas, especially after heat curing. Use this when the buyer wants broader colour freedom and can accept a firmer hand.

3. Sublimation or transfer on polyester fleece: Better for artwork detail and stronger colour, but it is not the same product experience as an unprinted throw. Sublimation only works on polyester-rich construction and usually performs better on smoother surfaces than on high-loft coral fleece. It can look cleaner than direct print, yet the pile still softens the image and can reduce edge sharpness.

4. Plain dyed base with embroidered or woven branding: This is the safest route when the brand needs repeatability and the artwork is small. It avoids print distortion entirely and often gives a more reliable buying result than forcing detailed art into fleece pile. The trade-off is less visual area for the message.

5. Unprinted throw plus branded packaging: If the blanket itself should stay understated, move brand expression to the belly band, insert card, satin ribbon, or woven label. This protects handfeel and reduces artwork risk. For related trim and presentation details, see embroidered patch application and heat-transfer woven labels.

4. Artwork rules that are production-ready

The old advice to “keep it simple” is directionally right but not enough for a PO. On 300gsm coral fleece, the pile height, nap direction, and binder migration set the real limit. A stable starting point is 1 to 3 colours for repeat production. Four colours can work on broad graphics, but the registration window narrows as the pile moves under the print head or screen.

For text, set measurable limits. As a sourcing rule, keep positive text at roughly 6 pt equivalent minimum for bold sans-serif, with reversed text at 8 pt minimum unless the line weight has been tested on the bulk fabric. Set the minimum positive line width at about 0.4 mm and reversed line width at 0.6 mm. Keep negative spaces in logos at least 0.5 mm where the art must survive laundering and pile movement. Thin serifs, hairlines, and dense gradients are poor candidates.

Require print-ready files in vector PDF, AI, or EPS, with Pantone references called out against the actual print route, not only against the screen preview. Raster artwork should be at least 300 dpi at final size. If the supplier is using screens, require separated colour layers, overprint instructions, trap allowances, and a defined tolerance for registration. The buyer should approve a strike-off on the actual bulk cloth and inspect it after wash, dry, and recovery. A sample that looks sharp only before laundering is not production approval.

For fleece specifically, require the strike-off on the same bulk cloth lot, after the final brushing and shearing step, not on lab yardage from an earlier stage. Ask the mill to mark nap direction on the strike-off and to show the artwork both ways if the graphic has directional elements. Pile compression is a real failure mode: a print can look clean in the press room and then blur after folding, vacuum packing, or a 30 to 40 degree C wash cycle. The PO should say that final approval depends on wash-tested bulk cloth, not on pre-wash studio samples.

5. Handfeel is the main failure mode

With fleece, the biggest mistake is treating print quality as only visual. On coral fleece, the common failure is a patch that feels boardy, glossy, or dead compared with the surrounding fabric. That usually comes from too much binder, too much heat, or pile compression during finishing. Once the nap is flattened, the throw loses the soft-selling point that justified coral fleece in the first place.

A good result should keep the decorated area only slightly firmer than the surrounding fabric. If the print feels plasticky, the binder load is too high. If it feels chalky or powdery, the chemistry and after-wash balance are off. Ask for a handfeel approval sample from the same fabric lot, not a studio mock-up made on a different base.

This is where low-build print has a narrow use case. It can reduce surface build-up, but if it depends on an unstable substrate or aggressive chemistry, consistency drops from lot to lot. When the buyer values touch and drape more than graphic detail, a woven label, embroidery, or packaging branding is often the better procurement choice.

6. EXW Ningbo costing: what should be on the quote

An EXW quote should separate fabric, cut-and-sew, decoration, packing, and yield loss. For a 300gsm coral fleece throw in a common size such as 127 x 152 cm or 150 x 200 cm, the fabric and sewing usually dominate. Decoration cost then depends on coverage, colour count, strike-off loops, and reject risk. A simple one-colour logo is a different commercial object from an all-over print with tight registration.

A usable quote should list these lines separately: base fabric cost, fabric loss allowance, cutting, sewing, print or transfer setup, screen or plate charges if applicable, curing, post-wash if required, label application, polybag or belly band, inner carton, master carton, and QC allowance. Add the commercial terms buyers compare: MOQ, strike-off charge, screen/plate charge, colour-change fee, overrun/underrun tolerance, and defect allowance. For smaller orders, sampling and make-ready can materially change the first-run price; ask for sample cost, bulk unit cost, and repeat-order cost as separate numbers.

A buyer-ready quote template should request the following commercial and technical line items: fabric GSM tolerance, finished size tolerance, decoration coverage percentage, print process name, artwork colour count, decoration loss allowance, packing spec, carton pack ratio, carton dimensions, gross/net carton weight, inner polybag gauge, master carton burst strength if retail-handled, and rework policy for print misregister or shade drift. If the order is for export, also ask whether the quote is truly EXW or includes inland freight to port, because that changes the comparison. If you need an apples-to-apples landed comparison, benchmark EXW against FOB Ningbo, not against an all-in quote with unclear freight assumptions. For freight logic, see FOB Ningbo vs DDP costing.

7. Inspection, acceptance, and tolerance controls

The PO should define what a pass looks like before production starts. State the fibre composition, finished GSM tolerance, print placement, colour target, handfeel expectation, and packing format. For a 300gsm article, a finished weight tolerance of roughly +/- 5 percent is a reasonable commercial target for a stable program, while a looser +/- 8 percent band may be necessary where brushing, washing, or pile finishing creates more variation. Set the tolerance to the route, not to a generic blanket rule.

Use an explicit AQL and defect list. For promotional soft goods, AQL 2.5 for major defects and AQL 4.0 for minor defects is common. Define major defects as wrong print placement, wrong base shade, broken logo, severe handfeel patch, oil stain, hole, open seam, or failed wash fastness. Define minor defects as slight thread ends, small label skew, or light shade drift within the approved range. Without those definitions, AQL is just a number.

For laboratory references, state the exact method and acceptance rule in the spec sheet: wash cycle, number of laundering cycles, crocking grading threshold, pilling class, and any dimensional change limit after wash. For example, a buyer might specify ISO 6330 at 40C with 5 wash cycles, ISO 105-X12 dry crocking minimum grade 3-4, wet crocking minimum grade 3, ISO 105-C06 colour change minimum grade 4, and ISO 12945-2 pilling class 3 to 4 after the agreed cycle count. The exact numbers should match the intended use, but the point is the same: name the method, the cycle count, and the pass grade, or the supplier can treat the test as advisory only.

For production control, add an inline checklist to the tech pack: approved bulk cloth lot number, approved strike-off reference, nap direction marking, print registration tolerance, curing temperature band, post-wash result, packing count per carton, carton mark content, barcode position, and spare ratio for retail fill. This avoids the common failure where the lab sample passes but the mass run shifts on a different cloth lot or with a different cure setting.

8. Buyer checklist before placing the order

Use this checklist before signing the PO: confirm the fibre is polyester-rich if you want a print route that depends on polyester, confirm the print name is actual pigment, sublimation, transfer, or a defined low-build effect, confirm the strike-off will be made on the same bulk cloth lot, and confirm wash-tested approval is required before bulk release. Ask for the exact lab methods, not just the test names.

For artwork, check minimum line weight, small text size, colour count, and whether the art will sit across the nap or with the nap. Ask for one pre-production strike-off, one post-wash strike-off, and one bulk photo from the same cloth lot under neutral light. If the supplier cannot show all three, they do not yet have a stable control plan.

For commercial terms, ask for MOQ, EXW scope, overrun/underrun tolerance, defect allowance, rework policy, carton pack ratio, and lead time by stage: fabric booking, printing, sewing, packing, and final inspection. A cheap first quote that hides rework, shrink allowance, or packing extras will not stay cheap in production.

Frequently asked

Can you truly discharge print 100% polyester coral fleece? Usually no, not in the classic discharge sense. True discharge chemistry is built for cellulosic fibres. On 100% polyester coral fleece, buyers should expect pigment, sublimation, transfer, or a defined low-build specialty print effect instead. If a supplier uses the word discharge, ask them to explain the chemistry and provide wash-tested bulk samples.

Which print method gives the softest hand on coral fleece? A low-build print route or a small woven/embroidered branding element usually preserves hand best. Heavy pigment prints are more likely to create a boardy or glossy patch because the binder sits on the pile surface.

What lab tests should be named in the PO? At minimum, buyers usually specify ISO 105-C06 for wash fastness, ISO 105-X12 for crocking, ISO 6330 for laundering, and ISO 12945-2 for pilling. The PO should state the wash temperature, cycle count, and pass grade, not just the standard number.

Why insist on strike-off approval from the same bulk cloth lot? Because fleece pile, nap direction, and absorbency vary by lot. A sample on different cloth can hide registration loss, binder build-up, or colour shift that appears only in bulk production.

What should an EXW quote include? At minimum: fabric cost, cutting, sewing, decoration setup, print or transfer cost, packing, inner and outer carton cost, QC allowance, fabrication tolerances, overrun/underrun terms, and rework policy. If the order is export-bound, ask whether inland freight to port is excluded, because EXW stops at the factory gate.
