Digital BW, The Print

Paul,
You guys have surely forgotten more then I'll ever know in the printing area.. As far as the tooth brush thing..  All I could see is getting ink in allllllllll the wrong places when you fired it up. Maybe kinda scary.. I think the ink needs to be contained and the container subject to the vibration..

As far as using old ink with out stirring.. If it's settled in my opinion your screwed if you don't get the particles back in suspension properly.. I have a 10k that runs Jons K6 inks.. If it sits for over 2 weeks unused I find I have issues ..Longer then 3... real issues.. When the ink settles all your linearization's are useless.. If you use some amount of the ink in the carts then regardless of what you do the mix is different so your original linearization is off even if you agitate the carts. My nutty shaker solution seems to keep the process on the fence when things are slow so I'll stick to it.

I have pulled carts and gently shaken them religiously.. but if we get to vigorous with that we cause other issues. The high frequency vibrations in my opinion is the right answer all the way around.. Ernst suggestion is really the correct way to go.. My offering , is a bit off beat but I find it works.. even though it may not be well received amongst the group.. In my personal experience. The lines hold a lot of ink.. these are subject to settling just like that in the carts.. So if we get the inks in the carts back in suspension and don't deal with the lines I think were kidding ourselves. It has been an honest issue for me.. Like anyone on the group I just try to do my best.. I sort of recall Jon doing a post on one of the blogs.. hopefully I don't blow this.. but my recollection is that if he knows a machine will be idol for 3 weeks he purges it.. 

Paul as far as old inks.. I'm not a real player here but I have never found ink age to be an issue.. Not one time... If the inks are settled in the cart then that is another deal.. that is a pain.. and the price if over looked will show in the images. I think we can all get that the pigments can and do settle..

  That gives me an idea... I use an electric toothbrush every am. I change the brush every 3-4 months. I dug an old one out of the wastebasket... what I trimmed the bristles and used that to stir up the ink? I'd have to be careful not to get carbon ink all over the main unit. But it vibrates something fierce.

  BTW, what happens if I used this old ink, without stirring?

  > Here's an optional suggestion.. Ernst.. I hope you read this also.. Their is another option.. I posted it maybe a good year ago and well nobody bit on it.. I think I freaked everyone out.. I honestly do this here and the stuff is still working..( It's used on a 7600 and a 10K) So guys.. I'm serious .. this is not a joke and it sure seems to work really well.. 
  > Ok so adult toys.. as in vibrators.. I bought a rig.. that was composed of two vibrating kinda egg things.. The control mechanism would run either or both..and you could dial in how crazy you wanted either of them to run (vibrate).. Originally I used it with batteries but quickly converted it to a small plug in power source.. So here's what I can do.... I can tape or Velcro it to the ink feed lines on a large format printer that isn't used very much ...It sends it little vibrations across the entire set of lines so the inks in the lines stay suspended.. I can take the two eggs and rubber band them to two ink cart's and in less then 20 minutes ( I've been doing this for a while so that's my honest recipe assessment ) their done.. As a note I have an ultrasonic rig complements of my sister in law ( It's a fancy ring cleaner).. My vote goes to this odd quasi adult process. You guys can all laugh if you want to.. I understand.. but I will say I kinda laugh most of the times I use this set up too.. I even have a few customers that have found incredible amusement in my odd ball process..
