Custom Photo Tshirt OEM Manufacturing From 100 Units

Classic And Long-Sleeve Core

160–180 GSM ring-spun cotton crewnecks target broad wholesale, event, and everyday markets. Center-chest photos, left-chest marks, and full-back artwork create reliable core-color programs. 180–220 GSM long-sleeves add sleeve-print real estate and extend the collection into transitional weather. Use them for tour merchandise, layered looks, or a higher average order value.

• Crewneck: regular silhouette, accessible opening price
• Long-sleeve: regular silhouette, sleeve graphics
• Photo placement: chest, back, sleeve

Oversized And Heavyweight

220–260 GSM oversized jerseys serve streetwear customers seeking dropped shoulders, wider bodies, and longer or boxier proportions. Large front photos, shoulder-to-shoulder back prints, and oversized halftones read best on this canvas. 240–300 GSM heavyweight tees justify premium pricing when fabric recovery, neck rib, and construction match the weight. Keep photographic artwork intentional: a smaller chest image can signal a more refined product.

• Oversized: youth and streetwear capsules
• Heavyweight: premium retail and limited drops
• Photo placement: large front or full back

Washed And Extended-Size

180–240 GSM garment-dyed, acid-washed, or vintage-look tees appeal to customers wanting a broken-in aesthetic. Test photo contrast after washing because fading and surface variation can soften image detail. XS–3XL programs need more than an enlarged base pattern: shoulder balance, body length, sleeve opening, and photo placement should be graded deliberately. Extended sizing broadens the customer base and supports inclusive core collections.

• Washed: vintage capsules and band-inspired assortments
• Extended-size: consistent artwork placement across sizes
• Photo placement: centered chest or back, scaled by size

Fiber And Knit Comparison

100% cotton offers a natural hand and strong screen-print adhesion, while ring-spun and combed yarns create a smoother, less hairy surface for sharper halftones. Open-end cotton costs less but can look more textured under detailed artwork.

Weight, Shrinkage, And Color

180 GSM suits mainstream short-sleeve tees; 200–240 GSM gives premium structure and better opacity for pale inks. Pre-shrunk fabric and controlled compaction reduce post-wash measurement drift, protecting image placement and fit consistency. White and light shades reproduce DTG and sublimation colors most accurately, while dark grounds need an opaque underbase. Garment-dyed fabric creates a washed, individual character, but dye variation and seams require artwork placement tests.

• 160–180 GSM: hot-climate, value retail
• 180–200 GSM: versatile branded retail
• 200–240 GSM: heavyweight premium programs

Match Fabric To Print

60/40 cotton-poly blends dry faster, resist wrinkles, and suit active or warm-climate programs, though polyester can affect discharge results. Recycled cotton or recycled polyester supports material-positioned collections, but variable fiber length makes strike-offs essential. 100% combed cotton is the dependable choice for DTG and detailed water-based prints; polyester-rich light fabrics suit dye sublimation. Screen printing tolerates more fabric variation, but smooth combed surfaces still improve small type and photographic gradients.

Digital Methods

DTG prints directly into cotton-rich garments and gives the softest photographic result on light tees; a white underbase makes it viable on dark colors. It suits samples and small runs, although pretreatment and slower per-piece output raise unit cost. DTF transfers full-color artwork from film onto cotton, blends, and dark garments with flexible placement. Its slightly more noticeable film feel is traded for fast setup, consistent color, and practical low-MOQ production.

Volume Print Choices

Screen printing uses separated colors and a screen for each color, producing durable prints with a low hand feel when inks are properly cured. Setup cost favors repeat artwork and larger OEM runs, while simulated-process separations can reproduce detailed photos. Sublimation permanently dyes polyester fibers and delivers unrestricted color with no surface feel, but it requires light or white polyester garments. It is unsuitable for black cotton photo tees.

Effects And Placement

HTV is cut from colored film, making it best for names, simple graphics, and one-off placement rather than fine photographs. Puff ink, reflective transfers, foil, or high-density details work best as controlled accents over a photo image. 100-unit programs benefit from approving a wash-tested strike-off that checks underbase opacity, cracking, edge adhesion, and color shift. Large-volume orders should lock artwork, Pantone targets, curing conditions, and placement tolerances before bulk.

Neck And Shoulder Stability

1×1 rib collars should recover cleanly after a 10% hand stretch, without permanent waves or a loose neckline. Specify collar width, rib composition, and neck-opening measurement in the tech pack. 6 mm to 10 mm neck tape should cover the back-neck seam, while shoulder-to-shoulder tape reduces stretching on heavier jerseys. Check that tape ends are secure and do not create puckering.

• Stretch collar and release it three times
• Inspect neck tape at both shoulder ends
• Check twin-needle stitching is even

Seams, Sleeves, And Shape

8 to 12 stitches per inch is a practical starting range for T-shirt seams; the correct setting depends on fabric weight and yarn. Look for balanced overlock seams, no skipped stitches, and controlled seam allowance. 2 sleeve openings should sit at matching angles when the garment is laid flat. Confirm side-seam alignment or, for tubular bodies, consistent twisting tolerance after wash.

• Match sleeve lengths and openings
• Check hem and cuff coverstitch
• Measure body twist after laundering

Wash Test And Approval Checklist

3 wash cycles at the intended care temperature reveal most avoidable failures before bulk approval. Record shrinkage separately for body length, chest width, collar opening, print area, and torque. XS through 3XL grading must preserve shoulder balance, body proportion, and sleeve length rather than merely scaling every point equally. Verify main, size, and care labels against the approved artwork and market requirements.

• Compare measurements against graded tolerances
• Photograph and retain the washed sample record
• Approve packed labeling before final balance

Confirm Production Ownership

100-unit programs need a written map of who prints, sews, washes, and performs final inspection. Ask whether DTG, screen printing, DTF, and heat transfer are in-house or subcontracted, and request the subcontractor’s controls if applicable. 4-color artwork should be approved against a Pantone target or signed digital proof. Request production photos, print-registration tolerances, and retained strike-offs from each colorway.

• Factory address and production-line photos
• Print method and subcontracting disclosure
• Artwork proof, Pantone callouts, strike-off approval

Test Materials And Samples

160–220 GSM ring-spun cotton and cotton blends should be specified by composition, weight tolerance, shrinkage, and color standard. Ask for mill test reports and any applicable OEKO-TEX, GOTS, WRAP, or BSCI documentation rather than assuming certification. 2 approved samples are more useful than one: a fit sample and a production-standard pre-production sample. Wash-test both for shrinkage, cracking, colorfastness, hand feel, and image durability.

• Fabric swatch with composition and GSM
• Graded measurement chart from XS through 3XL
• Wash-test and rub-test results

Control Scale And Delivery

80,000-unit monthly capacity is relevant only when the factory confirms available line capacity for your delivery window. Compare stated MOQ by style, color, print placement, and size range; 100 units per style and color can suit a controlled capsule launch. 30–45 days after approval is a typical bulk-planning range, but obtain a dated critical path covering sourcing, sampling, printing, sewing, inspection, and freight. Define Incoterms such as EXW, FOB, or DDP, plus inspection level, defect remedy, and balance-before-shipment terms. 1 shared tech-pack revision log prevents artwork drift between sales, development, and production. Require a mutual NDA, restricted artwork access, file-return terms, and written approval before any substitution.

• Weekly status update with dated milestones
• AQL or agreed final-inspection standard
• Named contact for technical approvals

Artwork And Color Approval

300 dpi at final print size is the practical minimum for raster artwork; low-resolution files produce soft faces, jagged edges and unusable detail. Ask: Can you confirm the final file dimensions, resolution and print-ready color mode? Pantone references or approved physical strike-offs are safer than screen-only approval, because monitor calibration and ink-on-fabric appearance differ. Ask: Which physical sample or Pantone target controls color acceptance?

Fabric, Underbase And Shrinkage

150–220 GSM jersey can print very differently by fiber content, knit density and surface finish; selecting fabric before a print test risks dull color, migration or poor hand feel. Ask: Will this exact fabric receive a wash-tested print strike-off? White underbases make artwork visible on dark garments, but can alter color and add stiffness; shrinkage also changes post-wash measurements. Ask: What underbase, wash cycle and allowable shrinkage will the approval sample use?

Fit Tolerances And Quote Matching

XS–3XL assortments cannot be guessed from a single sample; inadequate extended-size planning causes stock imbalance and inconsistent grading. Ask: What size curve and graded measurement chart are approved for the order? 1–2 cm measurement tolerances, decoration size, fabric GSM, print colors, labels and packing must match before quotes are compared. Ask: Are all suppliers pricing the same bill of materials, tolerances and inspection standard?

Concept And Rights Review

Week 1 should define the customer, target price, 2-4 coordinated colorways, and sales channel. Confirm written rights for every photograph, model release, logo, typeface, and licensed artwork before sampling.

• Build a visual reference board
• Set retail price and margin target
• Record image ownership and approvals

Artwork And Tech Pack

Week 2 should deliver print-ready artwork at 300 DPI at final size, preferably with a transparent background. Add Pantone references, placement measurements, print dimensions, garment color, and a tech pack covering fabric, fit, labels, and stitching.

• Front, back, and neck placement
• Pantone color callouts
• Label and hangtag artwork

Sample, Test, And Approve

Weeks 3-4 should produce one prototype before bulk commitment. Review measurements, photo sharpness, hand feel, registration, and neck recovery; then wear-test and wash-test the approved sample at least three cycles for cracking, shrinkage, and color change.

• Approve a sealed production sample
• Confirm XS-3XL grading where required
• Sign off print placement tolerance

Book Production And Launch

After approval, reserve fabric and print capacity, then submit final size ratios and packaging files. Specify a branded neck label, size label, care label, hangtag, folding method, polybag warning requirements, and carton marks before the production order is released. At retail launch, photograph the approved bulk-equivalent sample and publish fit notes, garment measurements, and care guidance. Hold back 5-10% inventory for exchanges, seeding, and quality contingencies.

• Freeze artwork before bulk release
• Approve pre-production sample
• Match ecommerce images to final colorways
