Our Black-and-White Variable Contrast Paper is a professional-grade imaging solution engineered for high-precision enlarging and portrait printing. Featuring a uniform chlorobromide emulsion coated on a premium polyethylene (PE)-laminated base, this paper ensures exceptional stability and consistent tonal reproduction for photography and medical imaging applications.
Designed for versatility and efficiency, the paper is available in four distinct contrast grades (No. 1 to No. 4) and multiple professional finishes, including glossy, pearl, satin, and matte. Its advanced formulation allows for rapid exposure and fixing times, making it the ideal choice for high-temperature rapid processing environments without compromising image quality.

The product must be handled under a dark red safelight with a transmission spectrum above 630 nm. We recommend Lucky LZ-2 or Wratten No. 2 filters with a 15W bulb at a distance of at least 2 meters.
This paper is fully compatible with Lucky HB-18 developer, D-72, or similar black-and-white paper developers, and F-5 fixer.
Yes, custom sizes are available upon request to meet your specific project or imaging requirements.
To ensure the integrity of the emulsion, continuous exposure under the recommended safelights should not exceed 40 minutes.
Yes, while manual tray development is recommended for maximum control, satisfactory results can be achieved through machine processing.
The paper should be stored in its original packaging in a cool, dry environment to prevent degradation and maintain its superior shelf stability.
