Hi if anyone can help me with my manroland 202

We have a problem with the lower unit print is not coming out perfectly on solid colour horizontal banding we have changed ink rollers and set accordingly problem improved slightly when we changed rollers but still not 100% any ideas

Regards
Kurt

 

Did you try to change oscillator step? Try to eliminate dampening problem by printing without water see if it improves.

 

We have tryed to print without dampiming problem is the same regarding oscillator step what deg should we put it on

 

Its a hit or miss there is no set scale for this

 

HI Problem remained the same anyting wls we can do

 

Hi we have removed all oscillating on rollers that touch plate and dry solids are now almost perfect but as we print with damping its banding starts any other ideas

 

Used to run one of these machines we had a large copper roller that sat between water meter and water form it oscillates and would help reduce banding on solids. Was called McKinley roller.

 

Mine is crome. i also have an attachment that some how fits on top of the standerd damping system have you ever seen this before? and would you know how to install it?

Thanks

 

It sits astride water form and meter the handle on the roller itself drops on to water form

 

yes 5he one i have has a handel on it and has like 3 small rollers in it

 

It is about a stroke of the roller, it is necessary to adjust the damping rollers correctly and to check the ink button on the plate, also check the ink button of the ink rollers on the plate
Good luck

 

Its called Tandem and check your form rollers if they oscillate much try to close the ring to null movement -though ghosting might appear-
