TEKTOL BLACK is a liquid concentrate print developer designed to produce cold black to neutral tones with most papers, and can also provide crisp highlight contrast. Some papers display slightly warm blacks or olive blacks when processed in a standard print developer, but this developer will minimize this bias while maintaining rich blacks and bright whites. Tektol Black offers a modest range of toning effect with most archival toners, and is the ideal choice for printers who routinely use selenium or polysulfide (brown) toner to enhance the permanence of the prints. Prints developed in Tektol Black can be toned deeply enough for permanence, with a minimum of the warm hue typically associated with these toners. Tektol Black may be mixed with Tektol Standard as an additional control to obtain intermediate cold tones.
Dilute 1+9 for most applications, or 1+14 when greater control or economy is important.
