# Printing & Surface Decoration on Latex Sheet

> **Safety.** Solvent inks and chlorination chemistry belong to industrial PPE contexts. This article defines **good** in industrial terms — not a print-shop tutorial.

## Executive summary

NR sheet stretches like an elastomer, not like cotton. Decoration must survive large strain without cracking or peeling. Industrial stretch-ink patents use **polyurethane/polyester elastomer vehicles** with pigment dispersions on **latex rubber** substrates.[^2] Use this when judging whether an ink or transfer method matches NR elongation, and when surface finish (gloss vs matte) is ignored in prep.

## Why NR sheet is a hard print substrate

Vulcanized film must stretch to at least **twice** its length under stress and recover.[^1] Rigid textile inks assume the wrong substrate class until proven otherwise.

---

## Stretch-ink architecture

Stretchable ink patents combine polyester, **polyurethane elastomer**, pigment dispersion, and surfactants for **latex rubber** substrates with high elongation without cracking (US10487228 family).[^2]

---

## QC language

ASTM D751 adhesion, D3389 abrasion, and D1876 T-peel provide **method classes** for coating and flexible bonds.[^3][^4][^5]

See [Adhesives and Seam Integrity](/literature-reviews/adhesives-and-seam-integrity) for peel vocabulary.

## Surface prep literacy

Glazed former finish → shiny, vibrant colors; bisque → dull flat colors.[^6] Halogenation reduces tack permanently — see [Surface Finish Literacy](/literature-reviews/surface-finish-literacy-gloss-matte-bloom). Print-after-chlorination on fashion sheet needs its own prep branch.

## Sheet-based vs liquid latex work

**Sheet-based work:** decorate purchased face finish.

**Liquid latex work:** former or bed sets gloss before print; bulk color may be compounded — see [Pigment & Filler Decks](/literature-reviews/pigment-filler-decks-wearable-nr-film).

Industrial print-binder vocabulary (NBR/acrylate/SBR) for textiles — partial analogy to NR sheet decoration; polymer family must match substrate elongation.
