HD Print
HD (high-density) print is a screen printing technique that lays down a thick layer of ink to give the design a raised, three-dimensional effect. It runs with high-density plastisol ink, which is PVC-based and solidifies when heat-cured, or with high-density silicone ink, which stays flexible after curing.
VISUAL EFFECTS
Raised, three-dimensional print built from a thick ink layer
HAND-FEEL
Raised and textured; firm with plastisol, flexible with silicone
BENEFITS
A thick ink layer gives bold, raised graphics with a three-dimensional quality, and the print holds up through repeated washing and wear. The silicone version stays soft and flexible.
LIMITATIONS
The technique suits bold, simple designs, because fine detail is hard to hold in a thick ink layer. Very thick prints can crack over time on fabric that stretches often, and silicone takes longer to cure than plastisol, so curing temperature and time are set precisely.
PROCESS
[01] Design Creation
Prepare the design and mark the areas that will carry the raised finish.
[02] Screen Preparation
Coat the screens with high-density ink and check that they are tensioned for precise printing.
[03] Printing
Print the design on a screen printing press, with enough pressure to deposit a thick layer of ink for the raised effect.
[04] Curing
Cure the print in a conveyor dryer or heat press so the ink solidifies into a durable, raised finish.
[05] Quality Check
Let the garment cool, then inspect the print for texture, thickness and adhesion against the quality standard.
TO CONSIDER
Ink Selection
Select high-density inks that give the flexibility and finish required, and consider the colour and transparency of the ink.
Curing Temperature and Time
Control curing temperature and time precisely so the ink sets fully without overcuring or undercuring.
Print Placement
Plan where the high-density print sits on the garment, taking the flexibility of the garment into account.
Post-Curing Inspection
Inspect cured garments for consistent texture, thickness and adhesion, and address any quality issues before production continues.
