Matsui DS Hybrid UB White | Water-Based White Underbase Ink for Digital Hybrid Screen Printing — Build the Opaque White Foundation for Digital Color on M&R Digital Squeegee and ROQ Hybrid Presses
Matsui
Matsui DS Hybrid UB White is the standard white underbase ink for digital hybrid screen printing — the first screen-printed layer applied to dark garments before the digital inkjet CMYK pass. It provides the opaque white foundation that digital colors print onto, blocks dye migration from the garment, and creates a consistent surface for accurate color reproduction. Requires Digiace Digital Screen Clear printed over it for optimal digital ink bonding. Prints through 160 mesh. Cure at 320°F for 2–3 minutes. Works on cotton, blends, and performance fabrics. PVC-free. No pretreatment required.
Price range: $69.99 through $499.99
Description
DS Hybrid UB White — STEP 1 — Screen Printed First
Every vivid digital hybrid print on a dark garment starts here. Dark fabric absorbs and distorts digital inkjet colors — garment dye bleeds through, CMYK values shift, and the result looks muddy and off-color. UB White solves this by screen printing a solid, opaque white barrier between the dark garment and the digital color layer. It blocks dye migration, creates a bright reflective surface for accurate color, and gives the digital printhead a consistent base to print onto. UB White is the workhorse white in the Matsui digital hybrid system — reliable, versatile, and compatible with every fabric type.
