- Technical Information Sheet
• Adorama VGFB Matte is a variable contrast black and white enlarging paper with a double weight fiber base. The warmtone characteristics of this paper give warm black image tones, on a warm white base. Although a high speed paper, the warm characteristics of this paper do result in it being a slightly slower speed paper in comparison to the standard Gloss Variable Grade Fiber Based product, ie enlarger exposure times will be required to be slightly longer for this Adorama VGFB Matte product when directly compared to Adorama VGFB Gloss. The use of color filters permits selection of required contrast from a range of grades similar to that of graded papers, with the advantage to the user of reduced paper stock. The warm image tone gives a high quality paper with a consistent warm image tone across the grades, exhibits good sharpness and is suitable for dish processing.
• This paper is designed for use with tungsten or tungsten halogen light sources. Other light sources may give different contrast values. Exposure of the paper isstraightforward, depending on which filter system is in use. For Ilford Multigrade filters, grades 00 to 3.5 have the same speed (ISO P 250) and grades 4 and 5 require approximately twice the exposure. For the filter settings of table B, grades 0 to 4 have the same speed (ISO P 320). Grades 00 and 5 require more exposure (ISO P 250). When no filter is used, the paper has a contrast of approximately grade 2 and a speed of ISO P 640.
• Open only in a darkroom illuminated by safelights Ilford 904 or Kodak OC containing 15W bulbs or equivalent; red safelights may also be used. The safelights should be at least one metre from the paper at all times and good working practice of keeping exposure to safelight at a minimum should be adopted.
