Dye Sublimation Printing for Custom OEM Apparel

Transfer-Paper Sublimation

Transfer-paper sublimation prints mirrored artwork onto coated paper, then heat-presses it onto polyester fabric. It suits sampled graphics, placement prints, and controlled color matching.

Direct-To-Fabric Sublimation

Direct-to-fabric systems print dye directly onto prepared polyester, followed by fixation in a calender or steamer. They reduce paper handling but demand stable fabric preparation and careful strike-through control.

Roll-To-Roll Production

Roll-to-roll printing runs continuous fabric lengths for repeating patterns and larger programs. It offers efficient meterage and repeat registration, while color approval must account for each fabric lot.

Cut-Panel Printing

Cut-panel printing applies artwork to pattern pieces before sewing, enabling edge-to-edge jerseys, leggings, and engineered placement graphics. Seam allowances and panel alignment must be built into the production file.

Finished Garments And Substrates

Finished-garment sublimation works best on polyester blanks or specially coated items such as bags and caps. It is flexible for small runs, but seams, zippers, and uneven pressure can create lighter areas.

Polyester Content First

95–100% polyester is the practical range for vivid, durable dye sublimation printing. A 90/10 polyester-elastane fabric can work for fitted activewear, but test stretch areas for whitening and recovery after heat pressing.

• Avoid cotton-rich blends for full-color coverage
• Use white or very light base fabrics
• Request a heat-and-wash strike-off

Construction By End Use

140–180 GSM jersey suits lightweight fashion tees and layering pieces, while 180–240 GSM interlock gives a smoother face and more stable opacity. Open-hole mesh supports breathable sports panels; brushed polyester fleece works for cooler-weather casualwear when pile direction is controlled.

Linings And Accessories

75–120 GSM satin gives scarves, lining panels, and promotional accessories a glossy surface, but snag resistance is limited. Outerwear linings need low friction, dimensional stability, and a print test after any water-repellent coating; untreated polyester usually transfers more reliably.

• Specify coating before print testing
• Check lining color against shell fabric
• Test zipper and seam show-through

Placement And Print Architecture

Full-bleed layouts can cover front, back, sleeves, hoods, and side panels, while engineered artwork assigns a specific graphic to each cut piece. Repeat patterns tolerate grading better than centered placements, but a logo or face must be positioned away from seam allowances, pockets, zippers, and underarm joins. 3–5 mm of bleed beyond cut lines is a practical artwork allowance for panel edges. Request a marked production layout showing grain direction, panel names, and seam joins before approving a sample.

Color, Photos, And Personalization

Pantone references, approved fabric swatches, and a physical sample provide a stronger color target than an uncalibrated screen. Gradients and photo prints need high-resolution RGB source files; avoid enlarging low-resolution web images because softness and banding become visible on large panels. One-off names, numbers, or team identifiers can be built into variable print files when the order data is checked before printing. Supply a spreadsheet with exact spelling, size, placement, and proof-approval ownership.

Labels And Added Decoration

Sublimation delivers integrated all-over color, gradients, repeats, and photographic artwork, but it does not create raised texture or metallic hardware. Add embroidery, screen print, heat transfer, silicone print, or patches when the brief needs dimension, opacity, or a separate logo finish. Woven main labels, size labels, wash-care labels, hangtags, and branded packaging should be specified alongside neck finish and seam construction. A bulky patch or embroidery backing can alter drape, so confirm its location on the approved garment.

Set Print Acceptance Standards

Pantone-referenced targets should be checked under D65 light against the approved strike-off; agree tolerances, such as Delta E 2–3, before production. Confirm full strike-through where the fabric and design require it. 100% visual checks on laid-flat panels should reject banding, ghosting, poor registration, white creases, migration, and unprinted edges. Record defect location and repeat frequency by roll, panel, and print batch.

• Compare to signed strike-off, not a screen proof
• Inspect both face and reverse where relevant
• Define approved defects with photo examples

Test Garment Performance

Three wash cycles at the agreed care condition provide a practical pre-production screen for color change, bleeding, and migration. Test stretch zones after recovery; graphics must not crack, whiten excessively, or distort on the specified fabric stretch. Four-point fabric inspection should identify holes, snags, oil marks, barre, and knitting defects before printing. Check fabric weight, width, and stretch against the approved material specification.

• Wash and dry one approved sample per colorway
• Stretch-test chest, sleeve, and side-seam graphics
• Hold defective rolls before panel printing

Control Assembly And Inspection

First-piece approval should verify panel alignment, print placement, seam matching, measurements, and logo orientation before line release. Full-print garments need matched artwork across side seams, sleeves, pockets, and collars within the agreed tolerance. AQL sampling at final inspection should cover construction, measurements, decoration, packed appearance, and shade consistency. JUNSHEEN can retain approved patterns, graded size sets, and material records to make repeat-order checks consistent.

• Approve strike-off, fit sample, and pre-production sample
• Inspect incoming fabric, in-line sewing, and packed goods
• Photograph defects and document corrective actions

Verify Production Ownership

2 production routes require different oversight: in-house transfer printing offers faster troubleshooting, while outsourced printing needs documented file, color and delivery controls. Ask which steps are owned, where printing occurs, and who approves reprints. Request dated factory photos and a process map linking fabric receipt, print, cut and sewing.

Check Color And Fabric Controls

100% polyester and polyester-rich performance knits are typical sublimation bases; fiber content, white point and GSM materially affect color yield. Ask for Pantone-targeted strike-offs and retained swatches under agreed lighting. Request wash-test results after 5 cycles, including color change, staining and print migration observations. Confirm how the supplier profiles printers, paper, ink and each fabric base.

• Pantone-referenced strike-off
• Fabric composition and GSM record
• Five-wash test sample

Approve Fit Before Bulk

XS–3XL programs need engineered grading, not simple enlargement. Review measurement tolerances, shoulder balance, sleeve length, rise and mobility on a size set before production. JUNSHEEN can develop patterns and samples from a tech pack, reference garment or concept; obtain one signed pre-production sample that defines the bulk standard.

Audit Commercial Readiness

100-unit launches require clear capacity and communication commitments. Confirm the named contact, sampling timeline, bulk window, inspection points, rework procedure and shipment handoff in writing. Ask for applicable OEKO-TEX, GOTS, WRAP or BSCI evidence only where claimed, plus final-inspection reports and packed-goods photos. Compare supplier responses against the evidence, not assurances.

Match Fiber To Process

65% polyester is a practical minimum for strong color; low-polyester cotton blends produce muted, uneven results. Confirm fiber content, fabric color, GSM, and stretch recovery on a physical swatch before sampling.

Prepare Production-Ready Artwork

300 DPI artwork at final print size prevents soft logos, pixelation, and jagged gradients. Supply layered source files, Pantone references where relevant, and a placement map with bleed beyond cut lines. 10–15 mm bleed commonly protects edge-to-edge panels, while seam allowances can consume critical details. Mark no-print zones around overlock seams, collars, zippers, pockets, and side panels before the factory makes markers.

Approve Physical Color And Repeats

Pantone-like screen-print expectations do not transfer exactly because sublimation color depends on fabric, ink, transfer paper, press settings, and monitor calibration. Approve a pressed strike-off and garment sample, not only a digital mockup. 1 repeat mismatch at a side seam can make stripes, checks, and engineered graphics look visibly broken. Request a cut-panel or sewn sample showing repeat alignment, then complete wash and abrasion testing before bulk release.

Buy Beyond Unit Price

100-unit MOQ pricing can conceal costs from weak pattern control, rework, color variation, or missed delivery windows. Compare quotations against sample quality, inspection points, fabric traceability, decoration testing, and export support. 2 pre-production approvals—fit sample and sealed production sample—reduce preventable disputes. Choose a supplier that documents artwork, graded measurements, material records, and final inspection standards before accepting a deposit.

Build The Product Brief

Two to three hero silhouettes usually create a clearer first drop than six lightly stocked styles. Define end use, target fit, size range, retail price, and colorway count before requesting fabric. 150–220 GSM polyester interlock or performance knit is a common starting range for lightweight sublimated tops; heavier constructions suit outer layers. Record fiber content, stretch, hand feel, Pantone references, seams, labels, and packaging in a production-ready tech pack.

• Limit launch colorways to proven demand signals
• Specify artwork placement and print scale
• Include measurement tolerances and construction details

Approve Artwork And Fit

300 DPI artwork at final print scale, with embedded or outlined fonts, reduces avoidable prepress delays. Submit repeat dimensions, placement guides, and Pantone targets with the art file rather than relying on a screen preview. One prototype should confirm silhouette, color, and print placement before a size set is approved. Fit approval should cover shoulder balance, sleeve length, body proportion, mobility, and measurements from XS through 3XL where applicable.

• Approve strike-off color against physical fabric
• Freeze artwork after sample approval
• Document all changes in one revision log

Release Bulk With Gates

100 units per style and color require a planned size curve, not equal quantities in every size. Allocate units from expected customer demand, then confirm the curve before bulk cutting and printing begin. One pre-production sample is the final gate for fabric, artwork, labels, measurements, and packing. Junsheen can carry the program through in-line inspection, final packed-goods checks, and export delivery after written approval.

• Confirm bulk material before production
• Approve pre-production sample in writing
• Check final cartons against packing list
