Customized Tshirt Manufacturing From 100 Units

Crew Neck Essentials

180–220 GSM crew necks suit core retail programs and promotional capsules. Specify neck-rib recovery, shoulder width, body length, and a taped neck seam so the garment keeps a clean everyday profile after washing.

Oversized Streetwear

220–300 GSM oversized tees target streetwear and fashion-led drops. Control dropped-shoulder depth, chest ease, sleeve opening, and cropped or long body length; simply upsizing a regular block produces poor proportions.

Fitted And Baby Tees

160–200 GSM fitted styles work for women’s fashion, layering, and body-conscious assortments. Use stretch jersey where needed and approve a full graded size set, since bust shaping, armhole comfort, and length change quickly across sizes.

Polo And Long Sleeve

Polo shirts and long sleeves add a more polished or transitional-weather option to a customized tshirt range. Pique versus jersey, collar construction, placket depth, cuff rib, and sleeve length affect perceived value and retail suitability.

Performance And Extended Sizes

XS–3XL programs need deliberate grading for active, plus-size, and inclusive collections. Performance knits require stretch and recovery targets, while extended sizing needs adjusted shoulder balance, sleeve length, body proportion, and mobility rather than enlarged base patterns.

Fiber Choice And Handfeel

100% ring-spun cotton is breathable, matte, and absorbent; it suits water-based and discharge printing but can shrink without controlled compaction. Organic cotton delivers a similar natural handfeel, with certification documentation such as GOTS requiring supply-chain verification. Modal feels smoother and drapes more, but its softer surface needs careful print testing.

Blends And Performance

60/40 cotton-poly blends reduce shrinkage and improve abrasion resistance, although polyester can make discharge effects less predictable. 100% polyester is quick-drying and durable for sublimation, while recycled polyester offers comparable performance when traceability documentation is available. Both usually feel less natural than cotton.

Weight And Knit Structure

180 GSM single jersey balances breathability and cost for retail basics; open-end yarn is economical, while ring-spun yarn is softer and cleaner for print detail. 240 GSM heavyweight jersey gives structure, opacity, and better collar recovery when paired with a stable rib. Higher weight raises fabric consumption, freight, and target price.

Choose By Artwork

1–6 spot-color logos and large vector art favor screen printing; its separated screens add setup cost but lower the unit cost on repeat runs. Full-color photographs and short runs suit DTG or DTF. DTG prints into cotton-rich fabric, while DTF transfers complex artwork onto more fabric types with a noticeable film hand.

Build Texture And Positioning

3D puff ink, high-density ink, embroidery, and applique create tactile branding that reads premium on heavyweight jersey, fleece, and outerwear. 2–12 thread colors are typical for embroidery, and stitch count drives cost. Applique uses layered fabric and stitching; it suits collegiate graphics but adds labor and bulk.

Plan For Wash And MOQ

20–100 unit test runs usually favor DTF, DTG, heat transfer, or woven patches because they avoid screen charges or extensive color separation. 50+ wash-cycle durability depends on correct curing, fabric compatibility, and care labeling. Discharge gives a soft hand on dischargeable dark cotton, while heat transfers need tested adhesion and stretch recovery.

Stability And Recovery

3% to 5% shrinkage after the agreed wash method is a common commercial target for cotton jersey; the permitted result must be stated by length and width. 1×1 or 2×1 collar rib should recover after extension without waviness. Shoulder-to-shoulder tape stabilizes the neckline and reduces stretching on heavier 180–260 GSM jerseys.

Seams, Hems And Sides

8 to 12 stitches per inch is a typical lockstitch range for T-shirt seams, but stitch type must suit the fabric weight and required stretch. 4-thread overlock side seams, coverstitched hems, and reinforced shoulder seams should be specified rather than described as ‘premium.’ Side-seam versus tubular construction affects fit consistency, print placement, and grading control.

Fit Specifications And Testing

XS through 3XL grading requires defined increments for chest, body length, shoulder, sleeve, and neck opening; simply scaling a base pattern creates proportion errors. ±1 cm is a practical example of a measurement tolerance for many knit points, while critical dimensions may need a tighter rule. Wash tests should assess shrinkage, twisting, pilling, seam appearance, and colorfastness to laundering and rubbing.

Tech Pack Approval Controls

1 approved pre-production sample should carry the exact fabric, Pantone reference, trims, measurements, tolerance chart, seam construction, stitch count, and wash standard used for bulk. 100-unit capsule orders and larger repeats both benefit from retaining the approved sample, graded patterns, and test records. At JUNSHEEN, these documents turn subjective expectations into inspection checkpoints for incoming materials, in-line work, and packed goods.

Verify Relevant Capability

Request three recent, comparable style examples: fabric composition and GSM, decoration method, construction details, and finished size range. A knit specialist may not control heavy jersey, enzyme washes, or puff print as reliably as a factory producing them routinely.

• Ask for tech-pack-to-sample photos
• Review measurement sheets and grading rules
• Confirm in-house versus subcontracted processes

Test Sampling Discipline

Set a 7- to 14-day sample target only after the supplier confirms fabric availability and pattern workload. Require a sample invoice, revision log, measurement spec, Pantone callouts, and written approval gate before bulk cutting.

• Prototype sample
• Fit sample
• Pre-production sample

Audit Materials And Quality

Request supplier test reports or certificates where your market requires them, such as OEKO-TEX, GOTS, BSCI, WRAP, or REACH documentation. Confirm incoming-fabric inspection, in-line measurement checks, final AQL standard, and how defects are documented and corrected.

• Fabric test report
• Trim specifications
• Final inspection report

Check Scale And Export Readiness

Ask what happens when demand rises from 100 units to 5,000: which line produces it, monthly capacity, lead-time assumptions, and subcontractor controls. Verify export experience through packing-list, commercial-invoice, carton-mark, and shipping-document samples with sensitive details redacted.

• Who owns daily production updates?
• What capacity is reserved for repeat orders?
• What is the escalation path for delays?

Price-Only Supplier Selection

A quote 10–20% below comparable offers can omit fabric weight, print coverage, testing, or export packing. Compare a locked specification sheet and landed-cost assumptions before selecting; otherwise rework and claims erode margin.

Artwork And Decoration Files

Pantone references, vector AI/PDF files, print dimensions, and placement measurements should be approved together. A low-resolution logo or unspecified ink effect can cause blurred output, color disputes, and a missed production slot.

Fit And Wash Approval

XS–3XL grading cannot be validated from one base-size sample alone. Approve a size set and wash-tested sample against measurement tolerances; skipped checks can create returns, costly remakes, and inconsistent repeat orders.

MOQ, Timing, And Changes

A 100-unit style-and-color starting point still requires fabric availability, sampling, and bulk scheduling. Confirm the critical path before launch, then freeze approved specifications; late changes can trigger material loss, revised pricing, and delayed shipping.

Labels And Packing Requirements

US, UK, and EU sales may require market-specific fiber, care, origin, and safety labeling. Supply approved label artwork, barcode data, carton marks, folding method, and polybag rules before bulk; omissions can delay receiving or force relabeling.

Define The Collection Brief

Two customer facts should anchor the brief: target wearer and retail price. Specify silhouette, size range, color count, launch channel, and planned replenishment before requesting quotations. One capsule should begin with a controlled assortment, such as two silhouettes in two colors. Confirm the intended customized tshirt fit—standard, oversized, or extended-size—before pattern work starts.

Build Production-Ready Files

One tech pack should state measurements, tolerances, construction, labels, and packaging. Attach vector artwork, placement dimensions, Pantone references, and decoration callouts rather than relying on mockups. Three approval files prevent ambiguity: graded size chart, bill of materials, and artwork proof. Resolve missing seam, trim, or wash instructions before the sample is cut.

Sample Before Committing

One development sample tests proportion, hand feel, and decoration execution. Review fabric weight, shrinkage after washing, logo position, color accuracy, and measurements against the approved specification. Two decisions must be closed before bulk: fit approval and color approval. Request a revised sample when any critical measurement, print quality, or fabric behavior remains outside tolerance.

Approve Bulk And Fulfillment

A pre-production sample is the final production reference for fabric, trims, labels, packing, and workmanship. Sign it only after checking the complete size set and confirming the approved artwork version. Three inspection points reduce late surprises: incoming materials, in-line construction, and final packed goods. Book freight after carton marks, quantities, delivery address, and balance-payment timing are confirmed.
