Custom Tshirt Printing Built for Brand Growth

Screen Printing

1–6 spot-color graphics on cotton jersey or blends suit screen printing. Opaque plastisol gives strong dark-garment color; water-based ink feels softer. 100+ units usually spreads screen setup efficiently. Properly cured prints wash well, but photo art and frequent color changes add separations and cost.

DTG And DTF

DTG reproduces detailed, full-color artwork on high-cotton tees with a soft result. Pretreatment and fabric color affect brightness and consistency. DTF handles cotton, blends, and polyester with vivid color and low setup. Its transferred film can feel heavier and requires controlled pressing for wash durability.

Vinyl And Heat Transfer

1–2 color names, numbers, and simple logos suit cut vinyl or heat transfer. Cotton, polyester, and blends accept it, including small personalized runs. 10–50 pieces can be practical because artwork setup is minimal. Large solid areas feel plasticky, and edge lifting is the principal wash-risk.

Sublimation And Specialty Effects

100% polyester white or pale garments are required for dye sublimation. The dye becomes part of the fiber, producing all-over color with virtually no added hand. Discharge, puff, foil, flock, silicone, and high-density effects add texture or dimension. Each needs fabric and wash testing; discharge performance varies with garment dye chemistry.

Cotton And Organic Cotton

100% cotton accepts water-based, discharge, DTG, and screen inks well because its absorbent surface anchors color. Combed ring-spun yarn is smoother and less fuzzy than carded or open-end yarn, producing sharper fine detail. 160–220 GSM cotton suits retail tees; organic cotton requires a documented certification chain when GOTS claims are planned. Allow for controlled wash shrinkage and use opaque underbases on dark shades.

Blends And Performance Fibers

50/50 cotton-poly blends reduce shrinkage and add durability, but polyester can cause dye migration under heat. Low-bleed inks and a production cure test are essential for deep polyester colors. 100% polyester and recycled polyester manage moisture and dry quickly, making them appropriate for activewear. Sublimation requires high-polyester, usually light-colored fabric; DTF and screen print broaden design options.

Weight, Knit, And Opacity

180–260 GSM heavyweight jersey creates a structured premium silhouette and improves opacity for bold graphics. A compact single jersey surface generally prints cleaner than loose, uneven knitting. 4.5–6.5 oz promotional tees prioritize cost and breathability, while 6–8 oz fashion programs support a more substantial hand. Request finished-GSM tolerances after wash, especially for garment-dyed cotton.

Print Placement And Scale

A 28–32 cm full-front print reads like a graphic tee, while a 7–10 cm left-chest mark suits retail uniforms or understated labels. A 5–8 cm sleeve print and inside-neck print add recognition without competing with the front artwork. Specify placement from center-front, maximum dimensions, Pantone colors, and tolerance on the tech pack.

• Full front: strongest graphic impact
• Sleeve print: visible in layered outfits
• Neck print: replaces a separate label

Decoration Combinations

One primary decoration method usually produces a clearer product than three competing effects. Water-based screen print suits soft cotton hand feel; puff, high-density, foil, flocking, silicone, DTF, and embroidery create different height, sheen, and wash-risk profiles. Two decoration locations raise setup, handling, and inspection time. All-over sublimation requires polyester or a compatible blend and is planned before garment assembly; dense embroidery may need backing and can distort lightweight jersey.

Private Label Finish

Three private-label components—main label, size label, and wash-care label—make a blank garment identifiable as a branded product. Woven labels, neck tape, hangtags, custom patches, and branded mailers increase perceived value but add approvals and material lead time. One cohesive brief should match logo scale, ink colors, patch material, and packaging to the target price. Request digital artwork, label copy, placement drawings, and a pre-production sample before bulk approval.

Pattern, Fit, And Grading

XS–3XL size sets should be checked on body-relevant forms, not scaled blindly from one sample. Confirm shoulder slope, chest ease, body length, sleeve opening, and grading increments before approving bulk.

• Measure against the approved spec sheet
• Compare all sizes, not only the base size
• Check print placement after size grading

Collar And Shoulder Stability

1×1 or 2×1 rib collars need enough recovery to return after repeated stretching; a loose neck opening is a frequent return trigger. Inspect neck tape or shoulder-to-shoulder reinforcement, clean coverstitching, and balanced seam tension.

• Stretch the collar and allow full recovery
• Check tape ends and shoulder seams
• Look for skipped stitches or seam puckering

Fabric And Color Control

160–220 GSM jersey commonly suits premium printed tees, but the fabric must be stable before artwork is positioned. Request pre-shrinking or wash testing, then compare shade consistency under daylight against the approved Pantone or lab dip.

• Record wash shrinkage in length and width
• Inspect spirality after laundering
• Approve bulk shade against retained standard

Sample And Bulk Inspection

3 wash cycles provide a practical early screen for shrinkage, cracking, bleeding, and collar distortion before production release. During bulk QC, inspect measurements, stitch density, seams, print registration, and packed-garment appearance against the sealed sample.

• Retain an approved sealed sample
• Audit random cartons from each production lot
• Photograph defects and record corrective action

Verify Category And Capacity

Ask for recent reference samples matching your jersey weight, color count, placement, and print effect. A factory experienced in custom tshirt printing should explain whether screen print, DTF, DTG, discharge, water-based, puff, or silicone suits the artwork and expected wash life. Junsheen can support programs from 100 units per style and color and reports monthly capacity above 80,000 units. Confirm the available production slot, quoted lead time, and whether sampling or peak-season orders change that schedule.

• Which comparable tees were produced in the last 12 months?
• What is the MOQ by color, size run, and print method?
• Can you provide an approved bulk-reference sample?

Lock Materials And Artwork

Specify a fabric target before approving price: for example, 180–220 GSM ring-spun cotton jersey or a defined cotton blend. Request swatches, composition, shrinkage expectations, color standard, and any applicable OEKO-TEX, GOTS, WRAP, or BSCI documentation rather than assuming certification applies. Provide vector artwork, Pantone references, dimensions, placements, and print layers for preflight. Ask the supplier to flag fine lines, gradients, underbase needs, registration risk, and color limitations before a deposit is paid.

• Which fabric lot will the bulk order use?
• Will preflight include a print-size and placement proof?
• Which compliance documents apply to this exact material?

Approve Sampling And Quality Gates

Require a prototype, then a size set or pre-production sample when fit, decoration, or wash performance is critical. Junsheen’s development workflow can include pattern review, grading, fabric selection, and pre-production approval; record every approved measurement and trim detail. Set inspection checkpoints for incoming fabric, in-line sewing, measurements, decoration, wash appearance, and final packed goods. Before bulk approval, ask who signs off deviations, what AQL standard is used, and how reprints, rejects, or delivery delays are handled in writing.

• Is the bulk print matched to the approved sample?
• What measurement tolerances apply by size?
• Who sends inspection photos and reports before shipment?

Deliver Production-Ready Artwork

300 dpi artwork at final print size prevents soft edges, unintended halftones, and costly redraws. Supply vector AI, PDF, or EPS files, define Pantone references, and request a prepress proof before sampling.

Match Method To Fabric

180 GSM ring-spun jersey, fleece, and stretch blends accept ink differently; the cheapest method can crack, bleed, or feel heavy. Compare screen-print, DTF, DTG, and discharge on the actual fabric, not a paper quote.

Specify Tolerances And Color

±1–2 cm garment measurement tolerances and approved Pantone targets prevent disputes after delivery. State print placement, maximum variation, and color standard in the tech pack; approve a strike-off under normal viewing light.

Test Before Bulk Approval

3–5 wash cycles can reveal dye migration, ink cracking, shrinkage, or poor adhesion that a fresh sample hides. Wash-test the strike-off, record the method and temperature, then approve only the tested construction.

Protect Schedule And Design

2–4 weeks for sampling and additional bulk-production time can be lost to artwork revisions or late approvals. Build approval buffers and limit a tee to compatible embellishments; excessive prints, embroidery, patches, and washes increase distortion and rejection risk.

Define Audience And Assortment

One target customer and two to four core SKUs are enough for a first capsule; define intended fit, retail price, climate, and competitor references. Established retailers should also forecast channel allocation and replenishment depth. Three locked inputs before sampling are the size range, garment silhouette, and initial colorway count. Oversized proportions or XS–3XL grading require pattern decisions early; names, campaign imagery, and seasonal color extensions can evolve later.

Build Production-Ready Artwork

300 dpi artwork at final print size, Pantone references, placement measurements, and vector logos prevent interpretation errors. Supply AI, EPS, PDF, or editable source files alongside a tech pack. Two approval files should separate visual intent from factory instruction: a presentation mockup and a print-placement sheet. Lock ink colors, print dimensions, neckline, labels, and tolerance expectations before the sample is cut.

Select Fabric And Print Method

180–220 GSM ring-spun cotton jersey suits many premium tees, while 240 GSM supports a heavier streetwear hand feel. Match decoration to artwork: water-based screen print for soft coverage, plastisol for opacity, and DTF for detailed small runs. One physical swatch review should confirm shrinkage, opacity, hand feel, and wash behavior before bulk fabric booking. Finish treatments, alternate blanks, and extra artwork colorways can be tested after the first approved sample.

Sample, Approve, And Replenish

One prototype, one revision round, and a signed pre-production sample create a practical approval gate. Check chest width, body length, print registration, wash-care content, packing ratio, and final carton marks. Three compliance checks commonly affect export readiness: fiber content, country-of-origin marking, and destination-specific care labeling. Confirm quotation, production schedule, inspection standard, shipping terms, and branded packaging before bulk; reorder from retained patterns and material records after sell-through proves demand.
