Using this specific product
Speedball Flex Opaque Fabric Screen Printing Ink is listed here as the Fabric screen-printing ink version for screen printing, fabric, and heat setting. For printing on fabric or paper, the useful question is not simply whether the surface looks finished—it is whether the exact next-action milestone shown above has been reached.
Before you start
- Confirm the package says Fabric screen-printing ink; related versions can use different timing.
- For screen printing, fabric, and heat setting, pay particular attention to ink deposit, material type and airflow.
- The page does not give a numerical definition of overnight; the countdown uses 12 hours only as the minimum boundary of that ordinary-language period.
How to check readiness
Use the stated dry or heat-set test before stacking or washing. Confirm the required heat, pressure and dwell separately; elapsed air-dry time alone does not set ink.
Avoid this mistake
A dry surface can still offset under pressure or wash out before heat setting.
