For everyday cotton, 480 Series gives shops a creamy ink that is easy to control and has great long-term viscosity. It prints well wet-on-wet and produces a soft hand on light and medium garments.
Use a white underbase when the shirt color needs more coverage or bleed resistance. A heavy, even deposit helps prevent the blotchy look that can appear when colors are printed too thin over white.
* Note: For best results, always test print and cure on the actual fabric before production.
