Matsui HM Discharge White | High Mesh Premixed Discharge White for Halftone & Fine Detail White Discharge Art on Dark Cotton — The Softest White at 305 Mesh

Matsui HM Discharge White — The White That Whispers Detail

When the design calls for photorealistic white halftone art on a black tee — smooth tonal gradients, whisper-thin highlights, detailed faces and photographic imagery — HM Discharge White is the tool.

It prints through mesh up to 305/inch. At that mesh count, the dots are microscopic. The tonal range is wide. The gradients are smooth. And the hand feel is virtually zero — the discharged white is so thin and so embedded in the fibers that it feels like the fabric itself.

This is not the white you choose for heavy opaque spot fills. That is what Brite Discharge White does at low mesh. HM Discharge White is the white you choose when detail and softness outrank opacity and brightness.

Premixed convenience: Unlike HM Discharge Base (which is clear and requires Neo Pigments for color), HM Discharge White comes ready-loaded with white pigment. Add activator and print. No pigment mixing required for white.

The White Discharge Hierarchy — Brightness vs. Detail

Matsui’s discharge whites form a spectrum from maximum brightness to maximum detail:

Brite Discharge White → BRIGHTEST white. Highest pigment load. Lower mesh (up to 160). The whitest white for spot printing.

Brite Discharge Super 75 → Pre-blended bright white (75% Brite White + 25% Brite Base). Economical. Lower mesh (up to 160).

HM Discharge White → FINEST detail. Softest hand. Highest mesh (up to 305). The halftone white.

Brite White + HM White blended 50/50 → Brighter than HM alone, finer than Brite alone. Prints up to 230 mesh.

Choose based on the job: spot white → Brite White. Halftone white → HM White. Both → blend.

Recommended Additives for HM Discharge White Production

Pro tip — mesh lubricant: Mix 30% Softener MG + 70% water in a spray bottle. Wipe on the ink side of the mesh before printing. Lubricates the mesh threads and prevents ink from sticking in the open areas.

Production best practices: Less ink is better on the screen. Add a small amount and continuously add fresh, hydrated ink during the run. Do not let discharge ink sit unused in the screen.
