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.

Compatible with this fabric type at correct press temperature and pressure.

  • 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.

Embroidery

Excellent

Midweight-plus fabric supports dense stitch counts without distortion.

  • 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

Excellent

High-polyester fabric accepts sublimation dye fully.

  • Sublimation shows only on white or very light garment colors.

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

Recycled Polyester (rPET)
Recycled polyester (rPET) is polyester fiber re-extruded from reclaimed plastic, mostly PET bottles, performing like virgin poly while supporting a garment's sustainability claim.
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.
Odor-Resistant
Odor-resistant fabric carries an antimicrobial treatment — usually silver ion or a branded finish like Polygiene — that slows the bacteria causing sweat smell between washes.
Anti-Pilling
Anti-pilling is a fabric finish or yarn construction that keeps loose fibers from tangling into the small fuzzy balls that form on fleece and knit blends.
Ribbed Collar
A ribbed collar is a stretchy rib-knit neckband, usually 1x1 rib, whose recovery after stretching depends heavily on how much spandex is blended in.
Placket
A placket is the reinforced, buttoned front opening on a polo or henley, and its width and length set the boundary for where a left-chest logo can sit.
