Matsui Alpha Series Purple C | Ready-for-Use Water-Based and Dischargeable primary purple Ink — Print Straight from the Bucket or Mix Custom Pantone® Colors Using Your Pantone Book — No Software Required

Alpha Series Purple C — Ready for Use, No Base, No Software

Alpha Series Purple C is a complete ink. Open the container and print.

Unlike Neo Pigments (which are pigment concentrates that MUST be mixed into a separate base), Alpha Purple C is a ready-for-use ink that requires no base, no mixing software, and no pigment calculations. Print it straight from the bucket as a primary purple spot color, or blend it with other Alpha colors following the formulas printed directly in your Pantone Formula Guide.

Alpha Purple C is the primary purple — the starting point for most purple Pantone formulas. Blend with Rubine Red C for warm berry and plum tones. Blend with Violet C for deeper indigo. Blend with Reflex Blue C for royal purple. Add Trans White C for lavender and lilac pastels. Add Black C for dark eggplant and near-black purple.

Two Modes — Water-Based on Lights, Discharge on Darks

Mode 1: Water-based on light and medium garments. Print Alpha Purple C directly on white, ash, light-colored, or medium-colored cotton and cotton-poly blend garments. No activator needed. The ink deposits color on the fabric surface with an ultra-soft hand feel.

Mode 2: Discharge on dark 100% cotton. Add 3-8% Matsui or Printers Choice Discharge Activator by weight. The discharge chemistry removes the garment dye and replaces it with the Alpha color — embedded in the cotton fibers with zero surface buildup. 12-hour pot life once activated. 100% cotton with dischargeable (reactive) dyes only.

On dark garments WITHOUT discharge: Print over a white underbase. Use Under Base Blocker Gray (dark cotton) or Under Base Blocker Black LG (dark polyester/blends) under the white to prevent dye migration. Or print two hits with a flash in between.

How to Match Pantone® Colors — Book Formulas, No Software

Step 1: Customer selects a Pantone color from the Pantone Formula Guide.

Step 2: Open the book to the selected color. The formula is printed right there — showing pigment ratios by weight.

Step 3: Follow those ratios using Alpha Series colors. Weigh on a gram scale. Mix thoroughly.

Step 4: Print a test swatch on your actual garment. Compare to the Pantone page. Adjust if needed.

Important: Pantone book formulas are designed for ink on paper. Minor adjustments may be required for an exact visual match on fabric. Discharge ink colors shift upon complete curing — the wet color may differ from the final cured result. Always test before production.
