Custom Print Tshirt Manufacturing, Ready From 100 Units

Promotional And Retail Graphics

100–180 GSM promotional tees suit events, giveaways, and wholesale campaigns where unit cost and fast artwork approval outrank refined fit. Plastisol screen printing is usually the most economical route for simple, high-volume spot-color artwork. 180–240 GSM retail graphic tees target customers who judge hand feel, silhouette, and wash durability at point of sale. Ring-spun cotton, Pantone-approved prints, and a retained approved sample cost more initially but protect reorder consistency.

Private-Label And Streetwear

1 core block with controlled neck width, sleeve pitch, and grading supports private-label basics that must reorder across seasons. Woven labels, wash-care labels, and consistent fabric lots add setup discipline but reduce brand inconsistency. 240–300 GSM oversized styles serve streetwear labels needing dropped shoulders, longer sleeves, and deliberate body volume. Puff, high-density, embroidery, and applique create stronger retail impact, while complex placements increase labor and sampling revisions.

Performance And Extended Sizes

140–180 GSM performance shirts suit teams and activewear programs requiring moisture-management knits, stretch recovery, and sublimation-compatible light colors. Test decoration after wash because heat, dye migration, and seam stretch can affect results. XS–3XL extended-size programs need separate proportion decisions for shoulder balance, body length, sleeves, and grading increments rather than simple enlargement. A full size set raises development cost, yet gives retailers better fit control and fewer repeat-order corrections.

Fiber Selection And Printability

100% ring-spun cotton gives a soft, breathable hand and strong screen-print opacity, but can shrink unless pre-shrunk. Open-end cotton is cheaper and tougher-feeling, suited to value promotions rather than premium retail. 50/50 cotton-poly reduces shrinkage and improves wear life, although dye migration can affect light prints on dark polyester. Modal blends add drape and softness but cost more and need careful print testing.

Weight And Knit Structure

140–160 GSM jersey suits hot climates and layering; 180–220 GSM offers a more substantial retail hand. Jersey has one smooth print face and natural stretch, while interlock is denser, more opaque, and typically more stable. 240 GSM and above creates a heavyweight, oversized silhouette, but raises fabric, freight, and drying-time costs. Specify finished GSM after washing rather than greige weight.

Shrinkage And Compliance

3–5% residual shrinkage is a practical tolerance for many cotton programs after controlled pre-shrinking; confirm the test method, wash temperature, and measurement points. Enzyme washing may soften the hand but should be approved against print durability. OEKO-TEX Standard 100 addresses harmful substances, while GOTS applies stricter requirements to eligible organic textile supply chains. Recycled claims should be supported by transaction-level documentation where required.

Print Method Selection

1–6 spot-color logos and large opaque graphics suit screen print; screens and Pantone-matched inks create a durable, scalable result. DTG handles photographic art and color gradients with minimal setup, while DTF suits detailed multicolor placements on cotton blends.

• Screen print: strongest unit economics at 100+ pieces
• DTG: best for intricate art and low quantities
• DTF: vivid detail, slightly raised transfer hand

Finish And Durability

3D puff, high-density, silicone, foil, flock, and water-based inks create distinct retail cues; require an approved strike-off because texture and cracking behavior vary by fabric. Discharge removes dye on suitable dark cotton, leaving a soft hand, but dye chemistry and wash tests are essential.

• Puff: dimensional logos; avoid fine registration
• Water-based or discharge: softer hand; lower PVC use
• Plastisol: opaque coverage and dependable wash resistance

Branding Beyond The Print

1,000+ rub cycles are a useful internal benchmark for transfer adhesion checks, alongside customer wash testing. Embroidery gives premium texture for small chest logos but can pucker lightweight jersey; woven labels feel durable, while printed neck labels reduce bulk and irritation.

• Heat transfer: ideal for names, numbers, and short runs
• Embroidery: premium raised finish; limit dense large fills
• Printed labels: comfortable for next-to-skin necks

Base Garment Specifications

30/1 ring-spun cotton produces a smoother print surface than coarse open-end yarn; specify fiber content, yarn type, GSM, and allowable pilling level in the tech pack. 1×1 or 2×1 neck rib should recover after stretch, while shoulder-to-shoulder tape stabilizes the neckline. Request side seams, neckline width, hem shape, and sleeve opening measurements with ±0.5 cm tolerances.

• State fabric weight and composition
• Specify neck-rib composition and recovery
• Call out shoulder tape and side seams

Seams, Shrinkage, And Labels

10–12 stitches per inch is a practical starting point for overlock and coverstitch seams on jersey, subject to fabric weight. Specify seam allowance, thread color, bartacks where needed, and no skipped stitches. 3–5% wash shrinkage is commonly planned into cotton patterns, but the approved sample must define the actual method. Mark main-label, size-label, and care-label positions from fixed garment points, including orientation.

• Test measurements after the stated wash
• Record label distance from neckline
• Inspect seam roping and loose ends

Sample And Final Inspection

Pantone-referenced color and an agreed colorfastness test prevent avoidable shade disputes; request wash, rubbing, and perspiration requirements appropriate to the market. Confirm the approved sample after laundering, not only straight from production. 0.5–1.0 mm registration tolerance is a useful print target for multi-color artwork, depending on design complexity. Final inspection should compare random packed units against the approved sample for print placement, registration, cracking, measurements, labels, and workmanship.

• Approve a washed production sample
• Define print-placement measurement points
• Check random cartons before shipment

Verify Product And Print Expertise

Ask for three comparable custom print tshirt case studies showing fabric weight, print method, color count, and finished production photos. Request approved sample photos beside bulk goods and clarify whether screen printing, DTG, DTF, or transfers are produced in-house. Outsourced decoration requires named controls for strike-offs, Pantone matching, cure testing, and rework.

• Which print methods are in-house?
• Can you provide wash-test reports?
• Who approves bulk print strike-offs?

Test Development And Supply Controls

A 100-unit MOQ can work for a capsule, but confirm the MOQ by style, color, fabric, and decoration rather than accepting one headline figure. Ask for a sampling calendar, swatch options, pattern and grading ownership, and an approved-sample control retained for bulk inspection. Request fabric composition, GSM, shrinkage, colorfastness, and relevant OEKO-TEX, GOTS, WRAP, or BSCI evidence where claimed.

• What is the sample revision limit?
• Which fabric tests are available?
• Is the approved sample sealed?

Audit Delivery And Commercial Readiness

A factory claiming 80,000-plus monthly units should provide current line photos, capacity allocation, in-line inspection records, and final measurement reports. Confirm defect handling, AQL standard, export markets, Incoterms, and who manages packing lists and shipping documents. State payment timing in writing before production begins. JUNSHEEN’s published progression starts with full prepayment for a first order, while established relationships may qualify for lower deposits; balance is due before shipment.

• Can you share recent production-line photos?
• What AQL and measurement tolerance apply?
• Which payment milestones trigger production?

Price Before Specification

Two quotes can differ by 20% because fabric weight, print coverage, labels, and inspection are not matched; choosing the lowest figure can cause substitutions and margin loss. One signed specification sheet should list GSM, composition, decoration method, approved Pantone colors, tolerances, and packaging before comparing like-for-like quotes.

Artwork And Color Gaps

300-DPI artwork, vector logos, and separated spot colors are essential for clean screen printing; low-resolution files create blurry edges or unexpected setup charges. One Pantone reference and physical strike-off prevent subjective color disputes. Confirm whether artwork includes underbase, gradients, transparency, and the final print dimensions.

Testing And Approval Shortcuts

Three wash cycles can reveal shrinkage, cracking, crocking, or dye migration that a fresh sample conceals. Skipping wash testing risks returns after retail delivery. One approved sample is not enough without measurement tolerances and a signed size set. Measure chest, body length, sleeve, print placement, and shade against the approved standard.

Calendar And Delivery Blind Spots

30 to 60 days may be needed for development, materials, bulk production, inspection, and freight, while seasonal launch windows do not move. Underestimating lead time can force costly air shipments or missed wholesale deliveries. One packing list review should confirm carton marks, polybag rules, barcode labels, HS code support, country-of-origin marking, and destination import requirements before bulk packing.

Position The Launch

One target customer, price band, and launch channel should be set before artwork is commissioned. Define retail price, margin target, competitor references, and initial color count. Two launch colors usually create cleaner demand signals than five. Choose one core silhouette and a measured size curve before expanding the range.

Prepare Artwork And Specifications

One production pack should include vector artwork, Pantone references, print dimensions, placements, and garment views. State whether the artwork uses screen print, DTF, DTG, puff, or water-based ink. Three fit documents reduce ambiguity: a measurement chart, graded size spec, and construction callouts. Add fabric composition, target GSM, neck-rib specification, label files, and packaging requirements.

Quote, Sample, And Approve

Three to five capable suppliers are enough for a focused shortlist. Compare like-for-like quotations covering fabric, decoration colors, MOQ, sampling charge, lead time, packaging, and shipping terms. One prototype must be reviewed for fit, shrinkage, print registration, hand feel, and wash performance. Record revisions in writing, then approve a sealed pre-production sample before bulk cutting.

Control Production And Reorder

100 units per style and color can test conversion, returns, and size demand with limited inventory risk. During bulk production, inspect fabric, measurements, construction, decoration, and packed cartons against the approved sample. Thirty days after launch, review sell-through by size, color, channel, and return reason. Reorder proven winners first, then add colorways or silhouettes only when the data supports them.
