Tetenal COLORTEC C-41 Manual De Instrucciones página 7

It is important to set the drying temperature so that the film emerges flat from the drying cabinet. If

the emulsion side is buckled, then the drying temperature is too high. If the reverse side is buckled,
then the temperature is too low. The drying temperature needs to be adjusted to take account of
prevailing conditions, with due regard to relative humidity (seasonal variations).
The times given in the tables include times of approx. 10 sec for pouring out the bath concerned. The

times given for bleach fixing and final rinsing are minimum times and may be exceeded by up to 50%.
