Decoration compatibility

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

Cotton-dominant knit takes plastisol and water-based ink cleanly with standard cure settings.

  • 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.

Cotton-rich blend prints acceptably; expect a softer, more vintage result than 100% cotton.

  • 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.

  • 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.

Sublimation

Not Recommended

Cotton-dominant fabric does not bond sublimation dye.

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.
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.
Heather Fabric
Heather fabric is knit or woven from a blend of dyed and undyed fiber, creating a mottled two-tone look that usually signals polyester content.
Gusset
A gusset is a diamond-shaped panel of extra fabric set into an underarm or crotch seam to add stretch room and stop that seam from ripping under stress.
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.
Tear-Away Label
A tear-away label is a neck or side-seam tag stitched along a single perforated line so it pulls out cleanly by hand for private labeling.
