  • Fotoksiążka – więcej, niż zwykła pamiątka

    Wróciłeś z cudownych wakacji. Wszystko, co chciałeś uwieczniłeś na zdjęciach – teraz musisz tylko wymyślić, jak będziesz je przechowywał. Na dysku komputera? Niby jest to praktyczne rozwiązanie, ale czasem masz ochotę wrócić do tych chwil w miękkim fotelu, a nie przed monitorem.

Photochemicals for C-41 process

Fotoksiążka - strona główna » Photochemicals for C-41 process

 

C-41RA  is a four bath, rapid access process designed for minilab systems only. Wet processing time is approx. 6 min. 30 s. and, depending on the dryer efficiency, the resulting dry to dry time is approx. 9 min.  C-41 is compatible with AP 72 and similar processes.

Replenishment rates - The indicated replenishment rates are reference values, which depending on machine type, workload and exposure, can differ. Machine default settings for replenishment rates are usually in ml per 135-24 film. On some machines (i.e. Noritsu), the replenishment rates are set separately for each film format in ml per metre.

As a routine procedure, we recommend weekly checks of all chemical filters not forgetting the in-line ones and/or the poppet valves in the replenisher pump systems to ensure they are clean and free of obstruction. Blockages in the replenishment system will result in under replenishment causing process inconsistencies.

  • The Fixer concentrate (Art.-No. 102651) is used in processes C41RA and CN-16FA. When used in process CN16-FA the concentrate is used as “ready to use” - when used in process C41-RA, the concentrate must be diluted with water to make the Replenisher.

  • The Stabilizer STAB-BNP is compatible with NQ4-R / N4-R. It can be used universally in the processes C-41 RA, C-41 BNP, CN-16 Q, CN-16 FA and CN-16 L. The processing parameter are different, depending on the process.

  • Super Conditioner TSC is a tablet based Super Stabilizer (Super Rinse) for Fuji film- and paper processes. For mixing of replenisher and working solution tablets have to be dissolved in demineralised water. The processing parameter are different, depending on process.

  • The Stabilizer NQ4-R / N4-R is compatible with C41 STAB-BNP. It can be used in processes C-41 RA, C-41 BNP, CN-16 Q, CN-16 FA and CN-16 L. The processing parameters depend on the process used.
