Press Performance & Modifier Rules
- Viscosity & Shearing: High-density, short-body ink that shears out smoothly across high-tension screens without tack pull.
- Underbase & Wet-on-Wet: Fast-flashing properties prevent skin pickup on subsequent heads during high-speed automated runs.
- Viscosity Reduction: If necessary, modify with max 1–3% Curable Reducer by weight. Exceeding 5% risks opacity loss and fibrillation.
- Stretch & Elasticity: Maintains elongation across athletic jerseys and rib knits without cracking when fully cross-linked.
Technical Pressroom Parameters
| Operational Variable | Specification Standard | Shop Operational Notes |
|---|---|---|
| Chemical Chemistry | [Plastisol / Water-Based / Silicone] | 100% Solid, Non-phthalate, PVC-compliant formula. |
| Full Fusion Cure Temp | 320°F (160°C) | Ensure entire ink film depth reaches temperature, verified via donut probe. |
| Flash Gel Temp | 220°F – 240°F (105°–115°C) | Dry to touch; do not over-flash or subsequent colors will delaminate. |
| Emulsion Compatibility | Solvent-Resistant / Dual Cure / Pure Photopolymer | Requires standard solvent or plastisol-safe stencil systems. |
| Compatible Reducer | [Compatible Reducer Name] | Add sparingly by weight (1–3%); mix thoroughly prior to press setup. |
Diagnostic Troubleshooting (Shop Q&A)
Why is the cured ink cracking or peeling after the first wash?
Cracking is caused by under-curing. The entire ink layer down to the garment fibers must reach the specified fusion temperature (320°F / 160°C). Surface temp readings via infrared guns often read hotter than the lower layer; calibrate conveyor belt speed using a thermal cross-probe/donut probe.
How do I prevent garment fibers from fuzzing through (fibrillation)?
Fibrillation occurs when open cotton fibers break through a thin ink layer post-wash. Ensure your underbase screen uses an adequate emulsion-over-mesh (EOM) gasket (15–20%), smooth the garment print surface with a flattening screen or roller on head two, and ensure full fusion cure.
How can I avoid dye migration on 50/50 and 100% polyester apparel?
Polyester dyes sublimate into gas starting around 330°F. For polyester garments, use a dedicated Low-Bleed barrier white or run low-cure inks (fusing at 270°–280°F) to stay well below the garment dye vaporization threshold.
