I've finally acquired the final item I needed to begin color print processing (a Beseler print drum, bought via this eBay auction, if anybody cares). So today I tried my hand at it, using the chemistry and processing steps described here. Most of my prints came out OK -- or at least, the problems were obvious ones of exposure or color balance that I could correct. About 1/4 of the prints, though, have an odd green streak down the center, as shown in this example. I've tried Googling and searching the archives here but haven't found an explanation. My best guesses at this point are stray bits of water dribbling on the print before processing begins and improper coverage of the print in developer or another chemical. (I tried quantities of 75ml-100ml in my drum, but I'm really not certain what the correct amount is.) Any advice is appreciated. Thanks!

srs5694 said:Thanks for the suggestions. It could very well be a trickle of water or even a bit of blix; I've only got one drum and was doing prints in quick succession, washing and drying the drum between prints. Any tips on quickly drying the drum and its cap to avoid this problem? I tried using a hair dryer, but it didn't seem to be doing quite a complete enough job.
I'll also look into the pre-wash, but the placement of these streaks is suspicious; all three affected prints have a single streak right down the middle of the print. If the pre-wash were causing problems, I'd expect a more even pattern of streaks -- or did you get a single streak with your pre-wash problem, Mick?
