Description

Matsui 4-Color Process Magenta — M — Magenta plate

The Matsui 4-Color Process CMYK set brings full-color photographic screen printing to the Matsui water-based platform. Each color is semi-transparent and formulated to blend optically through halftone dots — the same principle as 4-color offset printing, applied to screen printing on light garments. Cmyk process magenta — the m in cmyk is the M — Magenta plate component. Use all four process colors together for photographic reproduction.

The CMYK Process Set — All 4 Colors

How 4-Color Process Screen Printing Works

Photographic full-color screen printing uses halftone dots of the four CMYK process colors to simulate continuous-tone imagery. Each color is printed through a separate stencil with halftone dot patterns. The dots blend optically at print distance to reproduce the full spectrum of color. Process inks must be semi-transparent to allow this optical blending — opaque inks would block the underlaying colors. All four Matsui process inks are formulated with the semi-transparency required for accurate color reproduction on white and light garments.

Additives

AdditiveDosagePurpose
Retarder MG1–3%Extends open time — prevents ink drying in screen during longer runs.
Fixer WF-N1–3%Improves wash fastness — crosslinks binder for laundry durability.
Softener MG1–5%Improves fabric penetration and softens hand feel.
Thickener B0.25–1%Increases viscosity — thickens ink for halftone dot control.
RV Additive1–3%Reduces viscosity — thins ink for better flow and fabric penetration.
Fixer L1–3%Low-cure option for electric dryers where 320°F is difficult to reach.
Quick Additive6–9%All-in-one: Retarder MG + Fixer WF-N + Softener MG. Recommended for most jobs.

Technical Specifications

Do I need all four process colors?
Yes — for full-color photographic reproduction you need all four: Cyan, Magenta, Yellow, and Black (CMYK). Each produces a portion of the full-color image through its halftone pattern. Missing any one color will create an incomplete or color-shifted result.
Can I use process inks on dark garments?
4-color process inks are semi-transparent and designed for white or light garments. On dark garments the transparency causes the garment color to show through the ink, which corrupts the intended color reproduction. 4-color process is a light-garment technique.
What separations do I need?
Standard CMYK halftone separations. These can be generated from any image editing software (Photoshop, Illustrator) or RIP software. Each separation outputs a halftone positive for one process color channel.
What mesh should I use for process printing?
Higher mesh counts are generally better for fine halftone detail — 230 to 305/inch is typical for quality process work. The exact mesh depends on your halftone line frequency (LPI).
Do process inks need additives?
For most jobs, Quick Additive (6–9%) helps extend open time and improve wash fastness without affecting the semi-transparent formulation significantly. Avoid over-thickening process inks as this affects dot sharpness.
