Author Topic: bad print John Pytlak Film God Posts: 9987 From: Rochester, NY 14650-1922 Registered: Jan 2000 posted 09-22-2000 06:00 AM                        If you ever do get a new "wet" or "sticky" reel, ask for a replacement immediately! If there was a problem in drying the film, the gelatin emulsion will be softer, and much more likely to scratch, build up hard deposits in the gate, or pick up dirt. In my experience, poorly dried prints are very rare, but it can happen. ------------------ John P.

Even though I shouldn't be I am still amazed everytime I hear about the lack of training some people get. How could someone teach a person to be a "projectionist" and not even mention how to thread the Cat 700 properly? Do the teachers in these cases even know how to thread themselves?  |  IP: Logged Leo Enticknap Film God Posts: 7474 From: Loma Linda, CA Registered: Jul 2000 posted 09-23-2000 12:34 PM                        Brad - thanks for the FM-35 tip. I've wanted a way of bypassing the sensors for a long time. When running manually using changeovers, if you don't manage to stop the motor before the reel runs out then 'presence detect' alarms and raises the house lights. There have been times when this has happened about 10 secs after a perfect changeover, and I'm sick of it. Will investigate moving FM-35 units back. Have also had problems running silents - 16fps dosen't seem to be fast enough for 'motion detect' to work, so I have to bypass it using the microswitch in the TA-10. This should put an end to that, too. Dunno why I didn't think of it...  |  IP: Logged System Notices Forum Watchdog / Soup Nazi Posts: 215 Registered: Apr 2004 posted 05-26-2008 04:33 AM                 It has been 2801 days since the last post.  |  IP: Logged Ben LaCrosse Film Handler Posts: 27 From: Alpharetta, GA, USA Registered: Feb 2008 posted 05-26-2008 04:33 AM                     On the topic of cat 700 threading... If someone were to thread the reader at maximum tightness, for 4 shows in a row, would this cause areas of black on the soundtrack side? It is hard to explain, they happen so fast. Kinda splotchy, but instead of staying on screen like a normal scratch, they flash. This happened today, on both of our Dolbly cat 700 houses. Doing a walk-through when my shift came on and then I heard the sound. That film under high stress sound, like a prolonged ripping. Those tension rollers were wide open. And now there is this black smudge crap on both prints. I inspected the film and counted upwards of 7 scratches and reoccurring abrasions on the soundtrack side. The vertical scratches are not visible on screen. And maybe the blackness is the abraded areas I'm seeing. But can I safely argue that the negligent threading of the reader could have led to this? SDDS dfp 2000 reader sits on top of both readers, if that matters.  |  IP: Logged Sean McKinnon Phenomenal Film Handler Posts: 1712 From: Peabody Massachusetts Registered: Sep 2000 posted 05-26-2008 09:54 AM                        The rollers on the penthouse reader are bevelled so that even if the roller were to seize and stop spinning only the sprocket hole area of the film is in contact with the rollers. As far as having too much tension maybe it caused the film to buckle and come into contact with the rollers?  |  IP: Logged
