I have tried colour printing at home with a drum then a jobo processor. I found the biggest single variable was the temperature of the colour developer. The heat has to be within 0.1 degree centigrade. If you are processing in a drum with a heated water bath you can get to within 1 degree C, but in trays I doubt if it is anywhere near the correct heat of 38 degrees C. Any change in temperature between processing will give a magenta print if too hot and a green print if too cold. I suggest you get an automatic processor for a small studio. There are some drum processors that load the chemical at the right time and automatically empty the tank at the right time and keep the heat correct to 0.1 degree C. I think Jobo does one but there are others. It will save $$ on wasted paper but the outlay is likely to be high. About $1000???

I have a couple of questions. I have a processing drum but don't know how to use it correctly. I'm using processing trays for my prints. They keep on turning out all magenta or cyan. Does anybody have an online reference that I can look at to determine what my filters should be set at? Technical Info: *Kodak Professional Supra Endura Paper *Enlarger: Durst M601 *Chemicals for print processing: Beseler RA-4AT color developer and bleach, B&W stop bath, then wash with water **the paper box said to start with filters: 0C, 60M, and 45Y ***prints first turned out blue, then we made adjustments as directed, and then they turned out green, then we made more adjustments and they turned out red or magenta! _________________________________________________________________ Join the world’s largest e-mail service with MSN Hotmail. http://www.hotmail.com
