DTG & DTF Printing for Custom Apparel

Light And Dark DTG

Light-garment DTG prints directly onto pale, cotton-rich blanks without a white underbase, giving a soft, low-profile hand for detailed artwork and short runs. Dark-garment DTG adds a cured white underbase before CMYK ink, improving opacity but making pretreatment consistency and wash testing essential. Ask whether the supplier tests artwork on the actual garment color and provides a 5–10 wash sample.

DTF Film Variants

Cotton-focused DTF suits detailed logos, small mixed-color orders, and awkward placements where direct printing is impractical; its finish is typically smoother and more film-like than DTG. Stretch or performance-fabric DTF uses elastic film and adhesive for polyester blends, activewear, or rib areas. Ask for stretch-recovery, dye-migration, and 40°C wash-test results before approving bulk.

Gang Sheets And Ready Transfers

Gang-sheet transfers combine multiple logos or sizes on one film sheet, reducing setup waste for 100-unit capsule programs and repeat branding. Heat-applied ready transfers are preprinted, then pressed onto garments after production; they support inventory flexibility but require controlled temperature, pressure, and peel timing. Ask for sheet dimensions, minimum line weight, press settings, and replacement-transfer policy.

Fabric Comparison

160–220 GSM cotton jersey gives DTG a soft hand and reliable detail; cotton-rich blends also work well. Polyester, nylon, and most performance knits usually favor DTF for stronger opacity and adhesion. 280–360 GSM fleece needs a smooth, low-lint face, while brushed surfaces can obscure fine lines. Denim and textured slub knits should receive DTF strike-offs because seams, ridges, and uneven faces affect transfer contact.

Choose By Fiber And Surface

50/50 cotton-polyester can accept DTG, but results vary with the cotton percentage and dye migration risk. Tri-blends often produce a deliberately vintage, lower-opacity DTG look; use DTF when solid coverage is required. 100% polyester requires a low-temperature DTF process and migration testing, especially on red, navy, and black goods. WR or silicone softeners can block adhesion, so request untreated test panels or confirm finishing before bulk approval.

• Cotton jersey: DTG for soft, breathable prints
• Polyester: DTF with dye-migration testing
• Nylon: DTF after adhesion testing
• Performance knits: DTF on smooth, stable faces

Control Weight And Wash Results

180–240 GSM smooth jersey provides a stable print field; very lightweight knits can distort under curing. High-stretch elastane fabrics need DTF films selected for recovery, since rigid transfers can crack when worn. 3–5 pre-production wash cycles should test cracking, edge lift, fading, and color migration. Junsheen can review swatches and sample garments so the approved fabric, print method, and curing settings carry into bulk production.

Artwork And Color Files

300 DPI artwork at final print size is the practical starting point; supply transparent PNG files for DTG or DTF, plus vector AI, PDF, or SVG files for spot-color logos. Pantone references set expectations for branded colors, but digital inks, fabric shade, pretreatment, and underbase can shift the finished result. Approve a physical strike-off for gradients, photography, and critical colors.

• Provide transparent backgrounds and flattened final artwork
• Mark intended print dimensions in inches or centimeters
• Flag neon, metallic, and exact Pantone requirements

Placement And Personalization

1-inch placement tolerance is a sensible production allowance on chest, sleeve, back, and oversized prints; measure from stable landmarks such as the high-point shoulder or center back neck. 100-unit runs can divide into low-volume colorways, front-and-back combinations, sleeve logos, and individual names or numbers when the variable-data list is supplied in a clean spreadsheet.

• Left chest and full-back graphics
• Oversized front or wraparound placements
• Sleeve prints, names, and player numbers

Labels, Finishing, And Packs

2 label zones—neck and side seam—should be planned with print method, garment construction, and care requirements in mind. Printed neck labels suit soft jersey; woven main labels add a more structured private-label finish. JUNSHEEN can coordinate branded hang tags, polybags, size stickers, folding instructions, and carton marks with approved artwork. Mixed decoration, such as a DTF full-color graphic with puff screen-print lettering or embroidered chest logo, works best when each technique has a distinct visual job.

• Neck labels and wash-care labels
• Hang tags and branded polybags
• Carton marks for wholesale receiving

Ink And Transfer Controls

100% cotton DTG requires even pretreatment and opaque white-ink coverage; streaks, halos, or uneven underbase texture signal an unstable process. 75–90°C film peeling conditions, powder grade, transfer pressure, and curing time must follow the supplier’s specification. Record settings by fabric and colorway so reorders match.

• Check white underbase at edges and fine details.
• Match approved Pantone targets under consistent lighting.
• Confirm artwork registration around seams and panels.

Feel, Durability, And Migration

1 finished transfer should flex with the garment rather than feel like a stiff plaque. Excess powder or over-curing increases hand feel and can make large chest prints uncomfortable. 40°C wash testing should assess cracking, peeling, color loss, and edge lift after multiple cycles. Polyester and dark dyed fabrics require migration testing because sublimated dye can discolor light inks.

• Stretch the print across its widest dimension.
• Inspect peeled corners and fine-line adhesion.
• Compare washed samples with the sealed approval sample.

Buyer Approval Checklist

3 checkpoints—pre-production, in-line, and final packing—catch different failures. Junsheen can retain approved patterns, material records, and samples to support repeat-order consistency. AQL acceptance levels and sample quantities should be agreed before bulk begins. Inspect garments under daylight-equivalent lighting and after a full cure period.

• Verify garment color, measurements, placement, and registration.
• Check print opacity, hand feel, cracking, and peeling.
• Confirm wash-test result, labels, packing, and carton count.

Verify Fabric And Print Experience

160–280 GSM ring-spun jersey, French terry, fleece, and blended fabrics each accept inks and transfers differently; ask for comparable production samples. Request the supplier’s recommended pretreatment, print method, curing approach, and wash-test result for your exact fiber blend.

• Which fabrics have you printed repeatedly?
• Can you supply swatches before sampling?
• What wash-test cycle and pass criteria apply?

Control Sampling And Color

1 approved pre-production sample should match the bulk artwork file, placement tolerance, Pantone target, garment color, and size specification. Ask whether artwork cleanup, white-underbase settings, color proofs, and approval photos are documented before the production release.

• Who checks raster resolution and transparencies?
• How are Pantone deviations approved?
• What placement tolerance is used?

Test Operational Reliability

7–21 days is a common sampling window, while bulk lead time depends on fabric availability, decoration load, and final approvals. Request written QC records covering incoming fabric, measurements, print adhesion, packed-goods inspection, compliance documents, export terms, and shipment tracking.

• What is the confirmed MOQ by style and color?
• Can you share a QC inspection template?
• Which compliance certificates cover selected materials?
• Who owns daily production communication?

Price And Artwork Shortcuts

1 low quote can exclude artwork cleanup, white underbase, color matching, or test prints. Supply 300-DPI artwork at final size, separate spot colors where required, and compare like-for-like quotations before approving bulk.

• Avoid hairline details and unsupported transparency
• Confirm print dimensions and ink-color count
• Request a preflight report for every design

Garment And Sample Mismatches

180 GSM ring-spun cotton and brushed polyester fleece accept ink differently, especially with DTG pretreatment or DTF adhesion. Match the decoration method to the exact fabric, color, finish, and stretch level; approve a physical sample rather than a digital mockup. 3 wash cycles should check cracking, edge lift, shrinkage, hand feel, and color change. Review samples under daylight and specified retail lighting, then retain the approved standard for bulk QC.

Specifications, Timing, And Reorders

2 cm of placement ambiguity can create visibly inconsistent chest prints across a run. Provide measured reference points from neck, side seam, or center front, plus a placement diagram and tolerances. 14–28 days is a common production-planning range after approval, but fabric sourcing, sampling, and shipping add time. Lock Pantone targets, approved fabric lots, artwork files, size specifications, and wash-test records for repeat orders.

• Build sampling and transit time into launch dates
• Store approved print and garment standards
• Reconfirm material availability before reordering

Define The First Drop

One target customer should determine the garment, price band, and fit before artwork begins. Start with one hoodie, T-shirt, or sweatshirt silhouette and specify fabric weight, intended use, and XS–3XL grading. Two colorways are usually easier to launch than five because each additional color divides the size run and raises material complexity.

• Name the customer and selling climate
• Select one core silhouette
• Set retail price before costing

Lock Artwork And Brief

One production brief should include Pantone references, print dimensions, placement measurements, garment color, artwork files, labels, packaging, and tolerances. For dtg & dtf printing, approve the final artwork at actual print size rather than judging only a screen preview. Three files prevent common confusion: editable artwork, a placement sheet, and a tech pack or measurement specification.

Sample Before Bulk Approval

One prototype exposes fit, hand feel, print adhesion, color, and wash-performance issues before production. Revise the sample only against documented comments, then approve a sealed reference or pre-production sample. Two wash checks—after initial curing and after repeated laundering—are especially useful for digitally printed garments.

Build A Reorderable Size Run

A 100-unit MOQ can be split across one style and limited colors when the size curve reflects expected demand. Keep the first run concentrated in core sizes; avoid equal quantities from XS through 3XL unless sales data supports it. After delivery, retain approved patterns, graded size sets, fabric codes, print files, Pantones, and inspection records. Those records make reorders faster and reduce avoidable sampling changes.

• Inspect measurements and decoration before packing
• Track sales by color and size
• Reorder proven units before expanding variants
