I've seen more than one person on the site use the term "blooping" in referance to stopping splices from making popping noises in the sound sytem as they go by. Can someone explain?

If you do a search on it , there quite alot of info on that topic in the Forum.

i have never heard such a wonderful term, but i would guess it refers to using a marker to cover up the gap on the splice where the soundtrack is. am i close?

That's exactly it, Brian -Aaron

Something that works very well is a piece of black electrician's tape cut with a blade into an enlongated triangle shape. No wider than the soundtrack. Total length no longer than half an inch. Put it down after the first tape splice then cover it up with the second tape splice on the opposite side. In the military circuit we have the National Anthems and policy trailers that get used over and over. The splices will stretch some over time but the electrician's tape goes right along with it still blocking any light gaps that may develope. The reason for the triangular shape is to cut on/off the slit light gradually instead of all at once. (a gradient) No pop. No click. Not even a thump.
You can see these on some older SMTP headers. Seems it was used on the negative to bring up the soundtract from dead zero. Those old headers had the beep at the number "2". That's how I got the idea. Otherwise I was running out of grease pencils.

When I was in the business we used blooping ink(like printer's ink) which was supplied in a bottle and brush arrangement similar to women's nail varnish. A steady hand was required to paint a small "v" across the splice at the soundtrack to prevent popping if there was a gap in the splice. Of course the practice was entirely unnecessary if the splice was done properly in the first instance i.e. with no gap .Jim

At my place we cover the soundtrack gap by making a small mark with black chinagraph pencil.

Wouldn't it be easier to perform the splicer modification as mentioned in the "Tips" section?

I am not a great fan of overlapped splices. I have seen several trap assemblies have problems with them specificly some of the older straight gate turreted simplex and some of the prevost machines

The first roller on a newer Nuemade platter payout head has very little clearance. If you run some film where someone got lazy and did not remove the splicing tape from the last user and applied another, the film will get stuck for a moment, but pull through. An over lapping splice might be worse.

For tungsten light readers, "Blooping" ink or tape needs to be opaque to both visible and infrared energy, or it will not fully cover the analog sound "pop" at a splice. With red LED readers, the "bloop" just needs to be opaque to red light.------------------
