Ektacolor paper

It is symbolized by colored photosensitive paper sheets prepared to produce colored positive images printed or enlarged from colored negative films Ektacolor or Kodacolor. The appropriate safety light is the Wratten 10 H Safelight. To fix colors by dropping out during printing or enlarging, it is recommended to use Kodak Color printing Filters by C.P. Filters, their densities range from 25... to.... These filters are placed between the light source and the negative images. But if circumstances call for placing filters between the negative image and the sensitive paper (in front of the magnifier lens, for example), then a group of filters known as CC Filters (meaning Kodak Color Compensating Filters) is used, which we have previously referred to in Table 12, page 81 of this book. Kodak factories have not published Nothing about the compositions of the solutions required for the operations of displaying these papers, except that they are packed salts prepared for dissolving in containers of different sizes (suitable for one gallon of solutions, i.e. 1 liter, and others suitable for three gallons, i.e. 1385 liters). To be 2 gallons (i.e. 9 liters) of the solution after dissolving the salts.The failure to publish the original formulas of the solutions prompted one of the researchers, Ernest Gehret, to search for the preparation of alternative formulae (which we will mention starting from). 350). The work steps shown on p. 350 and the duration of treatment in solutions and temperatures agree with the same data published by Kodak factories on the treatment of these films in their original formulations produced by these factories, according to the formulations known by the following symbols (122 - Process, P). We show the steps as follows: - 5 pages. Completely sequence
