It is widely suitable for portraits, landscapes, architecture, and other photographic applications.

The product excels in processing durability and offers convenient development. It is compatible with all standard black-and-white paper developers, dries quickly, and maintains excellent flatness. It accommodates both room-temperature manual processing and high-temperature automated machine processing.

Safelighting

This product must be handled under a dark red safelight with a transmission spectrum above 630 nm. Recommended safelight filters include Lucky LZ-2, Wratten No. 2, or equivalents, using a 15W bulb at a minimum distance of 2 meters. Continuous exposure should not exceed 40 minutes.

This product is crafted with a uniform chlorobromide emulsion coated on a polyethylene (PE)-laminated paper base. It is available in four contrast grades (No. 1 to No. 4) and multiple surface finishes, including glossy, pearl, satin, and matte. The silver image tone exhibits high resistance to overdevelopment, with rapid exposure and fixing times, making it ideal for high-temperature rapid processing.

Key features include robust coating strength, excellent processing durability, superior shelf stability, and fast drying. It is particularly suited for portrait printing and enlarging, offering versatile options in contrast and texture to meet diverse user preferences for tonal range, finish, and sheen. The paper delivers low fog, high density, a bright white base, neutral black tones, crisp visual clarity, and rich gradation for outstanding image texture.
