Decoration compatibility

VisePrint guidance derived from this garment's stated fabric and construction — not manufacturer claims.

Prints well with a low-bleed ink system made for polyester; standard plastisol can dye-migrate.

  • Dye-migration risk on polyester content — use a low-bleed or poly-specific ink system and cure at lower temperatures.
  • Stretch content — use an ink with good elongation to avoid cracking.

DTF transfer

Conditional

Open or slick mesh surface — adhesion varies; run a wash test first.

  • High press heat can affect polyester — test temperature and dwell time before a full run.
  • Moisture-management finishes can reduce adhesion — verify wash durability on a test piece.

DTG printing

Not Recommended

Polyester-dominant fabric is a poor DTG substrate; choose DTF or screen printing instead.

  • Water-based DTG ink absorbs poorly into polyester and can wash out — pretreat and test.
  • Non-flat mesh surface reduces DTG detail.

Embroiders well with appropriate backing.

  • Lightweight or performance knit — use a stabilizer/backing to prevent puckering.
  • Stretch fabric — hoop with light tension and use a ballpoint needle.

Standard HTV and transfers apply well at the correct temperature for this fiber mix.

  • Use low-temperature transfer material to avoid scorch or dye migration on polyester.
  • Verify transfer adhesion over moisture-management finishes.

Sublimation

Conditional

Partial polyester content gives muted, distressed color rather than full saturation.

  • Cotton content will not hold sublimation dye — expect a faded, vintage result.

Decoration results can vary by equipment, ink, transfer material, garment color, and production settings. Always test before beginning a full production run.

Terms used on this page

Polyester
Polyester is a synthetic, petroleum-based fiber prized for durability, quick-dry performance, and colorfastness, but prone to dye migration under screen-print inks.
Spandex (Elastane)
Spandex, also called elastane, is a synthetic stretch fiber blended in small percentages into fitted and athletic apparel to add four-way stretch and recovery.
Mesh
Mesh is an open-construction knit fabric with visible holes for airflow, used in athletic jerseys, cap back panels, and moisture-wicking gear.
UPF (Ultraviolet Protection Factor)
UPF rates how much UV radiation a fabric blocks, from 15 (good) to 50+ (excellent, blocking over 97.5% of rays), tested under AATCC 183.
Crew neck
A crew neck is a round, close-fitting neckline finished with a ribbed collar band, the default cut on most t-shirts, sweatshirts, and hoodies.
Raglan Sleeve
A raglan sleeve is cut in one piece with the shoulder, creating a diagonal seam from underarm to collar instead of a rounded shoulder seam.
