Translucent strip on negatives from Hasselblad A12 back

[dave_lewis]

Hello,

 

I have a Hasselblad A12 back which is giving me problems and I'm

looking for a little guidance and insight. It's from 1988 and

mechanically gives me no problems. I purchased it used earlier this

year. I just had some enlargements done and noticed a translucent

strip that runs from top to bottom on the very right hand side of the

print. It is the same width from top to bottom and on a 9x9 print is

about a 1/4". The strip still shows everything on the print and

negative.

 

Going back over my contact sheets carefully, I notice it's been there

the whole time. Is this a symptom of a bad light seal or something

else? The line is there in nighttime and daytime shooting and doesn't

seem to be any worse in sunny or overcast weather.

 

Thanks for your help!

Might be time to change out the felt light traps.

Not sure what you mean by "translucent" on the print. A print can't be

translcent that I know of, do you mean its white? If its translucient on the

negative you would see a black strip on the print.

 

If you had a print that was of an 18% grey card that filled the intire image,

would the strip be white or black on the print?

 

Funny thing is, today I did a print and noticed a dark strip from top to bottom

on the far right. I looked back at other prints and have never seen it so I'm

going to have to watch this. If I look close it is on the neg.

Translucent means it transmits light, but presumably not as clearly as if the strip was not there - do you mean opaque? I guess too that you need a new felt trap - light is leaking in through the dark slide slit.

I have had the same problem. I found out the strip was a peice if film cut by the back's stainless steel blade. The strip gets stuck in the side, behind the blade frame.
