T-Shirt Screen Printing Service for Brand-Ready Custom Apparel

Manual Versus Automatic Printing

1–2-color runs, placements, and specialty registrations suit manual presses; automatic presses become more efficient for repeatable multi-color bulk runs. Automatic setups deliver tighter consistency, while manual printing supports flexible small-batch changeovers.

Plastisol Printing

Plastisol gives high opacity on light or dark cotton, blends, and many fleece garments. Its durable, vibrant film suits bold logos, but a heavier hand and PVC-related environmental considerations require deliberate specification.

Water-Based Printing

Water-based ink absorbs into cotton-rich jersey, producing a soft hand and breathable print. Opacity is lower on dark garments without an underbase, and wash testing should confirm colorfastness and cure quality.

Discharge Printing

Discharge printing removes dye from compatible 100% cotton garments, leaving an exceptionally soft result. Dark reactive-dyed shirts work best; dye response varies, so approve strike-offs before production.

Specialty-Effect Printing

Puff, high-density, silicone, foil, flock, and glow effects add dimension beyond standard ink. Fine details, stretch behavior, and abrasion resistance need sample review because each effect changes hand feel and artwork tolerance.

Fiber Content And Ink

100% ring-spun cotton accepts plastisol and water-based ink reliably, with a soft surface and low dye-migration risk. Combed organic cotton offers similar print behavior, but verify certification requirements and lot-to-lot shade consistency. 50/50 cotton-poly blends need low-bleed inks or a blocker underbase on dark colors. Polyester is lightweight and quick-drying, yet disperse dyes can migrate through white ink during curing.

• Ring-spun cotton: smoother print surface
• Open-end cotton: economical, rougher hand
• Polyester: use tested low-bleed systems

Weight By Program

140–160 GSM suits promotional and warm-weather tees, while 180–220 GSM supports a more substantial fashion hand. Heavyweight jersey at 220–280 GSM improves structure and opacity but increases material cost and drying time.

Preparation And Stability

3–5% residual shrinkage can distort print placement after washing unless fabric is pre-shrunk and the pattern allowance is confirmed. Tubular versus open-width knit also affects side seams, skew, and repeatable placement. Dark navy, red, and black fabrics require strike-off testing for underbase opacity, crocking, and dye migration. Confirm curing temperature against fiber content so the print bonds without scorching or excessive hand.

Prepare Artwork Precisely

Vector AI, PDF, or EPS files preserve clean edges; 300-dpi PNG artwork is suitable only at final print size. Supply each print dimension in millimeters, garment color, placement reference, and Pantone Solid Coated color callouts. A 5 mm placement tolerance is a practical approval point for chest, sleeve, and back prints, while oversized artwork needs a measured maximum width and side-seam clearance. Approve a digital separation and physical sample when fine lines, distressed texture, or close registration matters.

• Provide vector logos with outlined fonts
• State finished width and height
• Name each ink with Pantone reference
• Mark placement from neckline or center front

Choose Ink Effects Carefully

1-2 spot colors usually offer the clearest cost control and dependable registration on cotton jersey. Simulated process uses layered spot inks to reproduce detailed artwork, while halftones create tonal transitions without adding a separate ink for every shade. Puff, metallic, high-density, and glow inks add tactile or visual impact but increase curing, registration, and wash-test risk. Fine detail below roughly 1 mm and dense oversized ink coverage deserve a strike-off before bulk approval.

Build Details Into Placement

30-35 cm is a common adult front-print width, but the workable size changes with garment grade, neckline, and intended fit. Sleeve prints, neck prints, woven hem labels, and heat-transfer neck labels should be specified separately on the tech pack. 100-unit programs benefit from limiting special effects to one focal placement, then using woven or heat-transfer additions for secondary branding. That approach protects readability, reduces setup complexity, and keeps repeat orders easier to match.

Control The Blank

160–220 GSM is a common jersey range, but buyers should set an agreed fabric-weight tolerance and compare roll-to-roll hand feel. Check knit density, shade consistency, shrinkage, collar recovery, shoulder tape, and seam appearance before printing. 2–3 cm of collar height variation or uneven coverstitch can make an otherwise correct tee look off-spec. Approve a size-set sample with measured chest, length, sleeve, and collar specifications.

Verify Print Performance

1 mm registration tolerance is a practical target for multicolor artwork, especially around fine type and outlines. Review ink coverage, edge sharpness, Pantone target, underbase opacity, and placement from neck, center front, or side seam. 320°F/160°C is a typical plastisol curing benchmark, although the supplier must follow the ink system’s specified time and temperature. Request stretch-recovery checks and wash-test results for cracking, fading, dye migration, and adhesion.

Approve Before Bulk

3 approval stages reduce preventable disputes: strike-off, fit sample, and pre-production sample. The pre-production sample should use approved fabric, trim, artwork, placement, and finishing—not substitute development materials. 100% final inspection is not always necessary, but the agreed AQL level, measurement method, defect definitions, and carton count should be documented. Request signed approvals, Pantone references, wash-test records, curing data, and final inspection reports before shipment.

• Approved strike-off or production print sample
• Graded size-set measurement record
• Wash, stretch, and color-match test record
• Final AQL inspection and packing report

Relevant Factory Experience

Ask for production samples matching your fabric, ink effect and print placement; a 180 GSM ring-spun jersey behaves differently from open-end cotton. Request photos of comparable jobs and the approved artwork specifications. JUNSHEEN can combine garment development with plastisol, water-based, puff and high-density printing, which reduces handoffs between pattern, sewing and decoration teams.

Printing Control And MOQ

Ask whether screens, exposure, printing and curing are in-house or subcontracted, then request press, dryer and color-matching details. Outsourcing can work, but it adds approval and transit risk. A 100-unit per style-and-color starting point suits capsule programs; confirm whether the MOQ changes with fabric, print colors or specialty inks.

Sampling Capacity And Compliance

Request a pre-production sample, realistic sample-to-bulk timeline, monthly capacity and a written critical-path schedule. Check how strike-offs, Pantone approvals and size-set signoff are recorded. Ask which evidence is available for your market: fabric test reports, ink safety documentation and applicable OEKO-TEX, GOTS, WRAP or BSCI records. Never treat a logo claim as proof.

Quality Communication And Shipping

Set measurable acceptance points before bulk production: print registration, wash adhesion, measurement tolerances, packed-goods inspection and defect reporting. Ask for inspection records and production photos, not assurances alone. Confirm one accountable contact, response windows, export documents, Incoterms and shipment options. Final balances normally clear before shipment, so align freight lead time with your retail launch date.

Price Without Scope

$1.00 less per tee can disappear through reprints, freight, and markdowns when the quote excludes color count, Pantone matching, folding, or polybagging. Compare like-for-like specifications and approve a written costed bill of materials.

• Confirm fabric GSM and composition
• State ink colors and print locations
• Include labels, packaging, and inspection

Artwork And Fabric Mismatches

300 dpi artwork at final print size prevents jagged edges and weak halftones; a phone screenshot does not. Supply vector AI, EPS, or PDF files, plus linked fonts and Pantone references. 100% cotton accepts water-based and discharge systems differently from polyester or cotton-poly blends. Submit the actual garment fabric for strike-offs, especially for silicone, puff, discharge, or white underbases.

Unclear Bulk Approval

1 approved sample is not enough when placement, color, and construction remain verbal. Sign a pre-production sample with a placement sheet showing print dimensions and center-front or neckline measurements. 3 wash cycles should be completed before bulk approval to check cracking, adhesion, color bleed, shrinkage, and hand feel. Keep the approved sample and signed records as the production reference.

Timing And Color Risk

2 fabric lots can show visible shade variation, particularly in garment-dyed colors and heather blends. Approve a lab dip or bulk fabric cutting before printing and define acceptable Pantone tolerance. 4–8 weeks of production planning is safer than ordering against a fixed launch date with no buffer. Reserve sampling, revisions, curing, inspection, and international shipping time before announcing delivery.

Write The Product Brief

1 target customer, price point, channel and launch date should anchor the brief before artwork begins. Specify fit, fabric weight, colorway count, decoration placement, Pantone references and required labels. 2 core colors plus one seasonal color is usually easier to replenish than a broad first drop. Build XS–3XL ratios from customer data; do not grade demand evenly across every size.

Lock Blanks And Artwork

160–220 GSM ring-spun cotton suits many retail tees, while heavier jersey changes both hand feel and print behavior. Confirm blank measurements, shrinkage expectation and wash test before approving colors. 1 final art package should include vector files, print dimensions, ink colors and placement tolerances. Request a strike-off or decorated sample for the chosen t-shirt screen printing service.

Set Approval Gates

3 written gates prevent bulk surprises: fit sample, pre-production sample and production-ready purchase order. Freeze artwork, graded measurements, trim details and packaging at the PO gate. 100% of approvals should be dated and retained with the tech pack. At Junsheen, retained patterns, graded size sets and material records support more consistent repeat programs.

• Approve fit and size grading
• Approve print color and placement
• Approve packed production sample

Produce, Ship, Replenish

4 control points—fabric receipt, in-line sewing, decoration and final packed-goods inspection—should align with the approved sample. Confirm carton marks, units per carton and acceptable quality limits before final balance and shipment. 2 freight plans protect launch timing: a primary sea or rail plan and an air option for a small launch-critical allocation. Reorder from sell-through data early enough to cover production and transit, not after stockouts.
