Custom Tshirt Online Manufacturing, From 100 Units

Print-On-Demand Testing

One-unit print-on-demand suits creators validating artwork without inventory. It launches fastest, but base-garment choice, print placement, and margin control are limited.

Blank Tee Decoration

Twenty-four to 100 blank tees can suit events, merch drops, and local retail tests. Screen printing or embroidery improves identity, while the existing blank determines fit and fabric.

Private Label And OEM

100 units per style and color is a practical entry point for branded private-label or cut-and-sew programs. Private label modifies proven bases; OEM develops specifications, patterns, grading, materials, and trims for scalable differentiation.

Wholesale And Teamwear

100-plus identical units suit uniforms, schools, clubs, and reseller replenishment. Creative control stays focused on decoration and approved colors, but repeatability and purchasing efficiency are strong.

Cotton Fiber Choices

100% carded cotton is breathable and economical, but its more open yarn can feel drier and show less even print detail. Combed ringspun cotton removes short fibers, producing a softer, cleaner surface for premium screen print or DTG. 95/5 cotton-elastane adds recovery for fitted styles, while organic cotton requires credible transaction documentation when a GOTS claim is planned. Pre-shrinking or garment washing should be agreed because untreated cotton can shrink about 3–5%.

Weight, Opacity, And Season

150–180 GSM jersey suits warm-weather basics and layering, but pale colors may need testing for opacity. At 200–260 GSM, tighter construction improves drape, coverage, and perceived value for oversized silhouettes. 280 GSM and above creates a substantial heavyweight tee, though it dries more slowly and is less suitable for humid climates. Request a washed sample when hand feel, torque, and shrinkage matter.

Blends And Technical Options

60/40 cotton-poly blends resist wrinkles, dry faster, and usually shrink less than all-cotton, making them practical for uniforms. High polyester content can migrate dye under heat, so use low-bleed inks and test sublimation separately. 30–100% recycled fibers can support a lower-impact brief, but fiber content, certification scope, pilling, and shade variation require approval. Performance knits with moisture management suit activewear, not every water-based print process.

Choose The Print Method

1–6 spot-color artwork favors screen print, while DTG handles photographic shading on cotton and DTF carries full color onto varied blends. Heat transfer suits short runs; puff ink adds raised dimension, and discharge removes dye for a soft print on discharge-ready dark cotton.

• Screen print: economical for repeat bulk orders
• DTG: detailed artwork with minimal setup
• DTF: versatile transfer with a light film feel
• Embroidery: durable logos, limited tiny detail
• Appliqué: dimensional panels for premium sportswear

Compare Cost And Durability

20–50 pieces can justify DTG, DTF, or heat transfer, whereas screen-print setup spreads efficiently across larger runs. 30–50 wash tests are useful for confirming adhesion, cracking, dye migration, and colorfastness on the approved garment.

Prepare Approval-Ready Artwork

300 DPI raster files at final print size, or AI, EPS, PDF, and SVG vectors, reduce artwork conversion errors. Pantone references, placement measurements, print dimensions, and a transparent background should accompany every file. 1 strike-off should be requested when color matching, puff height, discharge behavior, foil, flocking, silicone, high-density ink, or specialty finishes matter. A sewn production sample is the safer approval point for embroidery, appliqué, mixed techniques, or dark fabrics prone to dye migration.

Yarn And Knit Consistency

100% ring-spun cotton jersey usually feels smoother than open-end yarn, while uneven courses, barre, or thin spots can become obvious after washing. 180–220 GSM is a common premium T-shirt range; review the sample under light and stretch several panels to confirm consistent opacity, weight, and surface.

Neckline And Shoulder Control

1×1 rib collars should recover after repeated stretching without rippling, and the rib width should match the intended fit rather than look undersized. 10–12 mm shoulder tape helps stabilize the seam and reduces shoulder stretch. Check that the tape lies flat, neck binding is even, and collar seams are cleanly joined.

Seams And Hem Finishing

8–12 stitches per inch is a practical inspection range for many jersey seams; low density can open under tension, while excessive density may pucker lightweight fabric. Side seams should hang straight, with matched underarm points and no twisting. Inspect double-needle hems for even distance, secure coverstitching, and no skipped stitches.

Wash Tests And Grading

3–5 wash cycles before bulk approval reveal shrinkage, torque, color loss, and collar recovery issues that a new sample can hide. XS–3XL grading must adjust shoulder, chest, body length, and sleeve proportion—not simply enlarge one base size. Approve measurement tolerances, wash-test results, and a full size set before production.

Verify Product Fit

Three recent T-shirt samples reveal more than a capability list: inspect neck rib recovery, shoulder tape, stitch density, shrinkage, print registration, and graded measurements. A supplier should explain whether it has handled your GSM, ring-spun cotton, oversized block, wash treatment, and decoration method before quoting.

• Request comparable production photos and measurement reports
• Ask for fabric composition, weight, and shrinkage tolerance
• Confirm MOQ by style, color, and size ratio

Test Development Communication

One complete RFQ should specify tech pack revision, Pantone colors, target GSM, composition, size range, artwork files, labels, packaging, quantity, Incoterm, and destination. Two sample rounds are common for a new fit; ask who owns pattern corrections, what is included, and how pre-production approval controls bulk work.

• Request a dated sampling and bulk-production timeline
• Require written measurement tolerances and test requirements
• Confirm one technical contact for revisions

Check Scale And Risk

80,000 monthly units is meaningful only when capacity is allocated after order confirmation. Ask how incoming fabric, in-line sewing, final measurements, decoration, and packed cartons are inspected. OEKO-TEX, GOTS, WRAP, or BSCI documents should be supplied when your market or retailer requires them; verify scope and validity rather than assuming coverage.

• Ask for export markets and Incoterm experience
• Compare deposits, balance timing, and sample charges
• Confirm repeat-order records for patterns and size sets

Approving Mockups Instead Of Samples

One digital mockup can conceal collar torque, print cracking, and shade variation. Approving it alone can leave a brand with 100 unsellable units. One pre-production sample in the final fabric, color, print method, and trims should be washed and measured before bulk release.

Selecting Fabric By GSM Alone

180 GSM jersey may feel crisp or flimsy depending on fiber length, knit density, yarn count, and finishing. GSM-only sourcing can produce a hand feel that misses the reference. Three checks—composition, shrinkage after washing, and stretch recovery—should accompany a swatch and finished sample.

Ignoring Fit And Artwork Limits

5% shrinkage can materially change body length, while untested grading can distort shoulders and sleeve balance from XS through 3XL. Lock a measurement chart, wash allowance, and graded size set before approval. 12-color artwork or fine halftones may not suit every screen-print process. Supply vector files, Pantone references, print dimensions, and a strike-off for approval.

Comparing Unit Price Only

A lower unit price can exclude labels, polybags, carton marks, inspection, or acceptable defect limits. The result is an incomplete landed-cost comparison and preventable rework. 100-unit programs should document label placement, packaging, measurement tolerances, approved defects, and balance timing in the purchase order before production starts.

Build A Production Brief

One product brief should specify silhouette, target retail price, competitor references, intended customer, and launch date before supplier outreach. A complete tech pack lists graded measurements, construction, Pantone colors, fabric GSM, trim callouts, label placement, and artwork files. Choose ring-spun jersey or other fabric only after reviewing hand feel, shrinkage, opacity, and wash performance.

• Confirm 100 units per style and color
• Set size ratios from expected buyers
• Limit the first launch to one or two colorways

Sample And Approve Fit

One prototype exposes pattern, print scale, sewing, and fabric issues before bulk commitment. Record each revision in a dated comment sheet rather than approving changes through scattered messages. XS–3XL size sets need fit approval across key sizes, not just a medium. Check chest, body length, shoulder balance, sleeve opening, shrinkage, and decoration alignment after wash testing.

Produce, Inspect, And Launch

A pre-production sample locks approved fabric, color, labels, packing method, and workmanship before the factory starts bulk production. In-line and final inspections should verify measurements, seams, print defects, quantities, and packed-carton markings. Three ecommerce assets should be ready before delivery: flat-lay images, on-body photography, and a precise size chart. Track sell-through by size and color, retain approved patterns and material records, then plan reorders before best-selling sizes stock out.

• Approve branded polybags, hang tags, and carton marks
• Request shipment documents before final balance
• Reserve repeat fabric where color continuity matters
