    Hello, New to the forums. Just wanted to get some feedback on the 07 105 universal. It was installed last November and I am finding it is a very hard press to control. We are not running conventional inks. We run sublimation dye in it. Does anyone have any tricks to get it settled down. It really seems like the damping system is what's causing the instability. I constantly have to reset waters, adjust skews and wash the metering rollers. I also adjust the curve selection. All my rollers settings are set correctly. One week it will run beautifully and then the next it's hard to hold on. Any suggestions would help. Thanks

    105U Ink Ductor Setting

    Hello,

    One of my customers has a 2006 KBA Rapida 105U press and is attempting to change and adjust their ink ductors for the first time. The manual lists them as 70mm but the factory rollers as well as both Botcher and Rotadyne replacements are 78mm. There is only one adjustment setting on the roller and they are having a heck of a time adjusting the stripe of the this roller to the osc and fountain ball. Have any of you set or adjusted this roller on your KBA? Any advise is greatly appreciated. Thank you in advance for your time.

    As far as your water issues what fountain solutions have you tried? I work with several brands and depending upon the sublimation dye and chemistry relationship they may not by working well together. I'm guessing being in California you aren't running alcohol so what Alcohol Subsitute are you using? I've found large differences in how these react with conventional and UV inks, so I'm sure sublimation dyes will react even more with these. How are you treating your Chrome rollers?

    I'm not sure if they changed the settings or not from the 2004 but on that press you engage the ductor with fountain ball off and make sure the console setting is at 100% duct. Jog the press until the ductor engages and moves toward the transfer roller as soon as it touches check that stripe. If it's too big or not touching unlock the lock screws on either end of the roller near the journal, believe it's a 5 to unlock and then 6 to make the adjustment. When you get a good stripe to the transfer adjust the bolt screws and lock. Your stripe to the fountain roller should be good once your transfer roller stripe is good. If you go too far then you have to start all over.

    Check your plate packing and blanket packing and make sure it's the same as the other units. All units should be packed the same. If it's a perma pack peal it off the corner and gage it out with a micrometer.
