Customize Tshirts From 100 Units

Core Crewnecks

160–200 GSM ring-spun jersey suits everyday crewnecks for broad retail customers and repeat-logo programs. Keep a regular shoulder and moderate body length; stable neck rib and shrinkage control matter more than novelty.

Streetwear And Heavyweight

220–280 GSM cotton supports oversized and heavyweight tees aimed at streetwear customers seeking structure and drop-shoulder volume. Specify body width, sleeve opening, neck-rib recovery, and garment-wash allowance before sampling.

Fitted And Performance

150–180 GSM stretch jersey suits fitted tees, while 140–180 GSM performance knits suit active customers. Test recovery, opacity, seam comfort, and print compatibility because close fits expose measurement and fabric variation.

Long Sleeves And Inclusive Fits

180–240 GSM long sleeves add transitional-season depth; extended-size programs require independent grading from XS through 3XL. Rebalance shoulder, sleeve, body, and armhole proportions instead of scaling one standard block.

Weight, Handfeel, And Opacity

140–160 GSM jersey suits lightweight promotional or warm-climate tees, but light colors may need opacity checks. A 180–220 GSM single jersey gives a more substantial handfeel and stronger retail presentation. 5% or less dimensional change after the agreed wash test is a practical approval target. Combed and ringspun yarns feel smoother than open-end cotton, while higher GSM generally improves opacity and durability.

Performance And Blend Selection

100% cotton is breathable and absorbent, making it dependable for premium basics and water-based prints. Polyester improves abrasion resistance, color retention, and moisture management, but can feel less natural and may retain odor. 50/50 and 60/40 cotton-poly blends balance softness, strength, and lower shrinkage for uniforms, active casualwear, and repeat programs. Recycled blends require clear fiber percentages because recycled polyester and recycled cotton affect handfeel and consistency differently.

Certification And Test Requests

GOTS applies to qualifying organic textile supply chains, while OEKO-TEX STANDARD 100 addresses harmful-substance testing in the certified article. Request current transaction or scope documents rather than relying on a logo claim. AATCC or ISO wash, colorfastness, pilling, spirality, and shrinkage tests should match the garment’s end use. Approve a washed fabric swatch and a decorated sample, especially for dark shades, pigment dye, and recycled blends.

• Confirm fiber-content tolerances and certification scope.
• Set wash method, temperature, and shrinkage limits.
• Test print adhesion after agreed wash cycles.

Print Method Comparison

One-color-to-six-color screen printing suits cotton jersey and repeat orders; each color needs a separate screen and setup. DTG handles photographic art on light cotton, while DTF carries fine multicolor artwork onto cotton blends and dark garments.

Match Method To Garment

100% polyester supports dye sublimation only where a pale, polyester-rich ground is acceptable; it performs poorly on cotton. Discharge produces a soft hand on dischargeable dark cotton but cannot reliably match every Pantone shade.

• Screen print: lowest unit cost at volume
• DTG: detailed, short-run cotton artwork
• DTF: versatile small runs; film handfeel
• Sublimation: all-over polyester graphics
• Discharge: soft vintage cotton effect

Texture And Premium Details

3D puff ink needs broad, uncluttered shapes because fine lines can close up after curing. Flat or puff embroidery suits left-chest logos and patches, but dense stitches can pucker lightweight jersey and feel heavy on large back art.

• Heat transfer suits names, numbers and limited placements
• Foil, flock and silicone add retail distinction
• Request wash tests for specialty finishes

Collar And Shoulder Stability

1×1 or 2×1 rib should be specified by composition, finished height, and neck-opening measurement; rib with elastane generally recovers better than loose all-cotton rib. Shoulder-to-shoulder tape must lie flat, cover the join cleanly, and prevent stretching without pulling the neckline.

• State rib width and finished collar height
• Approve neck recovery after a gentle stretch test
• Confirm tape color, width, and attachment method

Seams, Side Shape, And Hems

8–10 stitches per inch is a practical baseline for durable jersey seams, while hem and sleeve coverstitching should be even, untwisted, and free of skipped stitches. Side-seamed tees provide more reliable grading and side-label placement; tubular bodies can reduce side seams but require careful alignment of front graphics and grain.

• Match underarm seams at both sides
• Check hem depth and coverstitch consistency
• Inspect shoulder seams for puckering

Shrinkage And Measurement Control

3% or less residual shrinkage is a common target when the intended fabric and wash process permit it; require the test method, wash temperature, and tumble-dry condition in the report. Tech packs should list point-of-measure diagrams and tolerances, while the pre-production sample and final QC report should record actual measurements by size.

• Set chest, body length, sleeve, and neck tolerances
• Review fabric shrinkage before bulk cutting
• Compare graded sizes with the approved size set

Match Product Capability

100-unit MOQs can suit capsule launches, but confirm the MOQ applies per style, color, fabric, and decoration. Ask for comparable jersey weights, print methods, and size-range examples—not generic factory photos.

• Which T-shirt constructions run in-house?
• Can patterns grade from XS through 3XL?
• What is the repeat-order MOQ?

Audit Development And Materials

1 approved pre-production sample should lock measurements, Pantone references, artwork placement, labels, and packing. Request a quotation breakdown, fabric composition and GSM, shrinkage test results, and a dated critical-path schedule. 2 fabric options should be compared for hand feel, wash performance, lead time, and replenishment risk. A capable partner can source swatches and flag substitutions before cutting.

Verify Scale And Controls

80,000-plus monthly units may indicate capacity, but ask how many lines, operators, and active orders share it. Request inline and final inspection procedures, measurement tolerances, defect reports, and certification copies where claimed. 3 warning signs are vague sample dates, changing contacts, unexplained fabric substitutions, or refusal to provide production records. Check destination-market export experience and who owns booking, documents, and customs coordination.

• Ask for QC checklist and AQL standard
• Confirm weekly production-status reporting
• Verify payment milestones before deposit

Set Commercial Terms

100% prepayment can be normal for a first low-volume order, while established programs may move to staged deposits. Put sample charges, revision limits, balance timing, incoterms, and ownership of patterns and artwork in writing. 2 named contacts—commercial and production—reduce handoff errors across time zones. JUNSHEEN supports T/T, PayPal, and major credit cards, with terms reviewed as stable cooperation develops.

Specify Fabric Beyond Photos

180–220 GSM jersey can look similar online yet differ sharply in opacity, twist, and recovery. Buying from photos alone can cause returns; approve swatches, composition, GSM, and wash-tested hand feel. 3–5% shrinkage is common in cotton jersey after washing. Ignoring it changes finished measurements; require a shrinkage allowance and post-wash measurement report before grading.

Lock Fit And Sample Approval

XS–3XL grading cannot safely be inferred from a single medium sample. Under-specified shoulder, body, sleeve, and tolerance measurements create inconsistent fits; approve a graded spec and size set. 48 hours is often too short for a meaningful sample review. Rushed approval can lock in construction errors; wash, wear, measure, and photograph the sample against the tech pack.

Prepare Production-Ready Artwork

1 mm lines and small negative spaces may plug during screen printing. Unsuitable artwork produces muddy logos; submit vector files, Pantone references, print dimensions, and a strike-off approval. 3D puff, silicone, and high-density inks change hand feel and stretch. Skipping compatibility tests can crack decoration; test the selected ink on the actual fabric after laundering.

Control Commercial Details

1 missing wash-care label can block retail receiving or trigger relabeling costs. Overlooking packaging rules causes delays; approve label text, country-of-origin requirements, barcode placement, folds, and carton marks. 10–15% schedule buffer protects launches from fabric, sample, and freight variation. Chasing the lowest quote or booking no buffer invites quality compromises and missed drops; compare like-for-like specifications and reserve contingency time.

Define The Customer And Brief

1 target customer, price point, channel, and wear occasion should define silhouette, fit, color count, and target cost. The brand owner signs the product brief before development begins.

• Record target retail price and margin
• Specify regular, oversized, or extended-size fit
• Limit the first drop to controllable colorways

Build Production-Ready Specifications

1 tech pack should state measurements, construction, Pantone references, BOM, label placement, packaging, and tolerance rules. Supply print artwork as vector AI, PDF, or EPS with final dimensions and color separations. 100-unit programs still need a written quotation covering MOQ by style and color, sample charges, lead time, shipping terms, and payment milestones. The factory owner flags risks before sampling.

Approve Samples And Size Sets

1 prototype verifies proportions, fabric hand feel, print scale, and sewing method; it is not bulk authorization. Log every revision in dated comments, then approve a sealed sample or equivalent signed reference. XS–3XL grading requires measurement review at each critical size, especially chest, body length, shoulder, and sleeve balance. The brand owner approves fit; the factory owner confirms grading and repeatability.

Clear Bulk Release Gates

4 records should be complete before cutting: approved sample, final PO, bulk fabric and trim approval, and artwork/color confirmation. Require applicable compliance documents—such as OEKO-TEX, GOTS, WRAP, or BSCI—where the customer or market requires them. 1 pre-production meeting aligns cutting, decoration, measurements, packing, and inspection criteria. Changes after this point need written cost and timing approval.

Inspect And Deliver

3 inspection stages—incoming materials, in-line production, and final packed goods—should check shade, measurements, construction, decoration, labels, and carton counts. Release the balance and delivery only after the final report matches the approved standard.
