Description
Master printmakers and studio artists rely on Cranfield Traditional Lithographic Ink in Phthalo Blue (Red Shade) for its unmatched depth, buttery working consistency, and high-load pigmentation. Formulated specifically for stone lithography, aluminum plate lithography, and photolithography processes, this single-pigment formula delivers an exceptionally intense, warm-leaning cyan-blue that excels in both direct impression and delicate multi-plate color layering.
Manufactured in the United Kingdom using heritage triple-roll milling methods, this ink disperses fine-grade Alpha Copper Phthalocyanine (PB15:1) into high-grade polymerized linseed oils. The result is a mid-viscosity, stable body that rolls out smoothly into a velvet-thin film without tackiness, misting, or roller skid. Whether used straight from the tube for striking, high-contrast marks or extended with transparent base for luminous glazes, it maintains crisp line fidelity and clean dot reproduction.

-
Balanced Tack & Viscosity: Engineered specifically for the moisture-ink balance required in lithographic printing; rolls out evenly onto brayers and rollers.
