All Over Print Sublimation for Fit-Focused OEM Apparel

Transfer-Paper Sublimation

180–210°C heat and pressure transfer disperse dyes from printed paper into polyester fibers, giving strong repeatability on cut panels. 100% polyester goods produce the clearest color; cotton-rich fabrics require a different decoration method and should not be specified as sublimation.

Roll-To-Roll Printing

1.6–3.2 m production widths make roll-to-roll suitable for continuous yardage, repeating prints, and larger programs. Pantone references should be approved on the actual fabric, because knit texture, base whiteness, and finishing alter perceived color.

Panel And Finished Garments

2–5 mm seam shifts can change artwork placement, so panel printing is preferred for engineered graphics, matching sleeves, and full-coverage hoodies. Finished-garment sublimation suits simple polyester blanks but cannot reliably cover underarms, seams, labels, or deep folds.

Fiber Content And Color

100% polyester is the baseline for saturated color, sharp detail and reliable washfastness. Recycled polyester can print comparably, but supplier-to-supplier yarn variation makes a strike-off essential. 85/15 polyester-spandex improves recovery for leggings and fitted tops, while cotton-rich blends produce deliberately softer, less vivid results. Low-shine yarns and a clean, smooth face usually reproduce fine artwork better than textured surfaces.

Structure, Weight And Opacity

140–180 GSM interlock or jersey suits lightweight tees, whereas 180–240 GSM performance knits give more coverage and shape. Open mesh improves airflow but can make pale artwork and seam allowances more visible. 240–320 GSM polyester fleece supports hoodies and joggers, although its brushed surface softens micro-detail. Use a compatible printed lining or a solid polyester lining when the garment interior will be visible.

Stretch And Moisture Management

4-way stretch fabric must be tested while extended because dense dark artwork can look lighter under tension. Specify recovery, stretch direction and opacity during the fit-sample review. Wicking performance knits move moisture through engineered yarns or finishes; excessive softener can reduce that effect. Test print color, hand feel and moisture transfer after the intended wash cycle.

Artwork Layouts

3 layout types cover most collections: seamless repeats, engineered chest-to-hem placements, and photographic or gradient artwork. Engineered files must account for panel shapes, collar openings, seam allowances, and artwork lost inside overlock seams. XS–3XL programs need size-specific placement rules when a centered motif, face, logo, or border cannot simply scale with the garment. Junsheen can review panels and approve digital mockups before sampling.

• Use 300-dpi artwork at final print size
• Extend backgrounds beyond cut lines
• Mark grain direction and panel names

Branding Beyond The Print

4 complementary methods solve details sublimation should not: embroidery adds texture, patches create a removable badge effect, screen printing suits opaque spot graphics, and heat-applied logos work for small marks. Dense embroidery and heavy patches should be positioned after fit testing to avoid distortion on lightweight knits. 1 neck print, woven main label, size label, wash-care label, hang tag, and branded mailer can be specified as one private-label package. Decoration approvals should show exact logo dimensions, thread or ink colors, and attachment location.

Color And Approval Control

1 master artwork file should define Pantone targets, color builds, print scale, and version number. Sublimation produces gradients and photographic detail well, but the final result depends on fabric whiteness, polyester content, and approved sample viewing conditions. 2 approvals protect consistency: first approve the digital layout, then approve a physical strike-off or garment sample under agreed lighting. Retaining approved files, graded layouts, and material records supports accurate reorders.

Pattern And Panel Registration

A 3–5 mm seam allowance should be built into the print layout so critical motifs do not disappear into overlock stitching. Front, back, sleeve, hood, and pocket panels need clear grainline and placement references. A pre-production sample should confirm that stripes, checks, borders, and repeat motifs meet intentionally at visible seams. Ask the factory to flag unavoidable mismatches around curved armholes, collars, and underarms before bulk cutting.

Stitching And Reinforcement

Four-thread overlock seams suit most polyester jerseys, while coverstitch hems provide a flatter, more durable finish on tees and activewear. Stitch density, balanced thread tension, and trimmed seam tails prevent puckering and loose ends. Two-needle reinforcement at shoulder seams, pocket corners, and high-stress joins helps garments survive repeat wear. Inspect seam stretch by gently extending the sample; stitches should recover without popping or permanently wavering.

Collars Cuffs And Wash Testing

1×1 or 2×2 rib collars and cuffs require compatible recovery with the body fabric; overly soft rib can bag out after laundering. Neck tape and clean coverstitching help stabilize the neckline and improve comfort. Three wash cycles before approval can reveal seam torque, collar distortion, pilling, and print-related surface damage. Record measurements before and after washing, then approve a sealed production sample with the agreed tolerances.

Verify Relevant Production Experience

2–3 recent comparable styles reveal more than a generic print portfolio. Ask for photos of cut panels, finished seams, size ranges, and wash-tested garments. 100% polyester performancewear, mesh, and interlock behave differently under heat. Request fabric specifications, garment weights, and references for similar cut-and-sew programs.

Confirm Printing And Color Control

190–210°C transfer processes demand controlled press settings and repeatable artwork preparation. Ask whether sublimation is in-house or outsourced, who owns color approval, and how reprints are handled. Pantone targets should be approved on the final production fabric, not only on screen. Request strike-off swatches, ICC workflow details, and documented lot-to-lot color checks.

Test Development And MOQ Flexibility

100 units per style and color can suit a capsule, but minimums must be confirmed by fabric, print layout, and size mix. Ask for sample, size-set, and bulk lead times separately. XS–3XL programs need graded patterns rather than enlarged base sizes. Request measurement charts, patternmaking ownership terms, revision records, and a pre-production sample approval point.

Audit Quality And Delivery Support

AQL inspection should cover panel placement, measurements, seam construction, decoration, and packed quantities. Ask for inspection reports, defect handling procedures, and retained production records. OEKO-TEX, GOTS, WRAP, and BSCI claims require current supplier-specific documentation. Request compliance certificates where applicable, a named account contact, export terms, carton specifications, and shipping options.

Specify Fabric Performance

At 150–220 GSM, polyester-rich jersey typically produces vivid dye transfer; cotton-rich fabrics will not accept conventional sublimation consistently. Approve fiber content, GSM, stretch recovery, and a washed swatch before bulk booking. After the first wash, knit shrinkage and heat-related dimensional change can alter body length and print alignment. Require a wash test, allowable shrinkage tolerance, and measurement spec taken before and after washing.

Prepare Print-Ready Artwork

At 300 DPI at final print size, raster artwork retains detail; enlarged web graphics can create visible pixelation. Supply original files, embedded or linked fonts, and a defined RGB or CMYK workflow with Pantone references where color matters. Across a full garment panel, unplanned artwork can land on underarms, side seams, or zipper areas. Approve a panel map showing scale, repeat, seam locations, and the permitted placement tolerance.

Approve Physical Samples

One digital mockup can confirm intent, but it cannot reveal hand feel, seam distortion, strike-off color, or fit. Approve a printed strike-off and a sewn pre-production sample under normal lighting before releasing bulk. Two to three sample rounds are common when fit, artwork scale, and trims are still moving. Freeze the tech pack, graded measurements, artwork version, and comments after final approval to prevent mixed instructions.

Compare Total Manufacturing Value

A lower unit quote may exclude sampling, special packing, inspection, or realistic remake responsibility. Compare quotations against the same fabric specification, print coverage, construction, packaging, MOQ, and delivery terms. At a 100-unit style-and-color starting program, a supplier’s communication and repeat-order records often matter more than a small initial saving. Confirm the quality checklist, defect handling process, approval gates, and final balance timing in writing.

Build A Focused First Assortment

Three to five coordinated SKUs usually give a new label enough visual range without multiplying development risk. Use one core silhouette, such as a polyester performance tee or hoodie, across two colorways and one hero print. 100 units per style and color is a practical gate: consolidate demand into proven sizes and avoid launching four unrelated fits. Reserve extended-size grading only where customer data supports XS through 3XL demand.

Approve Production-Ready Inputs

One complete tech pack should specify graded measurements, fabric GSM, seam construction, Pantone references, label placement, and packaging. Supply repeat artwork at final scale with bleed, panel mapping, and clear placement marks before sampling. 1 prototype sample exposes fit, color migration, seam alignment, and artwork continuity. Revise the pattern or file once evidence is clear, then approve a sealed pre-production sample before bulk cutting.

Control Bulk And Delivery

80,000-plus monthly-unit capacity does not remove the need for a written production calendar. Confirm bulk fabric, approved trim, size ratios, inspection standard, and shipping method before the order moves from pre-production approval. 100% of packed goods should receive final checks for measurements, decoration, construction, labeling, and carton quantities. Retain approved patterns, graded size sets, and material records so a winning capsule can scale into repeat colorways or bulk programs.
