yes, list the model. is this web press? it depends on type.
We pioneered a unique and effective cost saving method to repair damaged printing cylinders caused by accident, erosion and corrosion. Damages, such as indentations on printing cylinders can be filled electrolytically with copper then hand-polished to its original concentricity. A cosmetic nickel is then plated for final finish.
The advantage of utilising Sterling Brush Plating or selective plating technology to repair damaged printing cylinder is that REPAIR CAN BE DONE INSITU. You SAVE ON DISASSEMBLY AND REASSEMBLY COSTS, REPLACEMENT OF NEW CYLINDERS, LABOUR COST AND PRODUCTION DOWNTIME.
Conventional electroplating requires plating tanks. The printing cylinder for repair is removed from the printing machine and sent to a workshop. Sterling Brush Plating will save you shipping, disassembly and reassembly costs by bringing electroplating services to your factory premises for the repair. The bond strength and metal hardness deposited is as good as conventional immersion electroplating.
We have been offering our on-site services to the varied industries in the Asia Pacific Region for more than 20 years now. The Sterling Brush Plating or selective plating process is your best professional decision to repair damaged printing cylinders.
If you have a problem with your printing cylinder, and would like to know more about the Sterling Brush Plating process, please contact us now.
Alternatively, we also offer hardchrome and copper plating immersion services.
Yours faithfully

Or you could do like we did and use bondo. One of our guys accidentally dropped a allen wrench in one of the presses trying to adjust the forms on the run and it got caught between the plate and blanket cylinders. We filed the raised portions flat and filled in the indentations with bondo. Of course you then have to shape the bondo afterwards.

Hello HachiZenki,
you can take a look at the URL attached.
Printing Application
We are transferring our technologies to interested parties who wish to conduct the repair in-house. You will be trained and handle the repairs by yourself. Above that, we will give you the technical support on consultations and will conduct your first and second repair together with your technicians. This training attachment will ensure the skills are adequately transferred.
Do consider the offer and write to me at ([email protected])
Thank You.
Best Regards,
Sunny Tan
We accidentally did that on a Komori Sys38 between the blanket cylinders on the 1st unit. We ground it down, added "quicksteel" and its been fine ever since. That was about 2 years ago. Of course we use steelback blankets, so that makes a little bit of a difference. I'd recommend it as a temp fix though, because the quicksteel wears away after a while.

Did you guys have to file it down or could you use regular sandpaper? See that's why we used bondo instead of something like JB Weld or something similar. Yes bondo shrinks a bit when it cures but it's way easier to work with.

Hi there, my company used to do electroplating on site up until a few years ago. When it comes to small dings such as ball bearings, electroplating takes a long time . Also you have to actually open it up larger to be effective in electroplating. The best way to repair ball bearing dings is to drill the ding the same diameter as the ding and then use a taper reamer and drive a taper pin in with red or green locktite cut off excess and file down to surface height of cylinder. This a permanent fix and only the area affected.

Ive done 2 part epoxy fixes, that depending on the size of the ding have lasted well over a year, and other than the visible fix on the cylinder showed nothing when printing even the most challenging impressions.
Our Process is called selective area plating or Brush Plating. We electroplate copper to fill the damage, file and blend to the contour of the cylinder, then deposit a hard nickel cap to provide wear resistance.
This process is used by OEM and press mechanics that want a permanent repair, guaranteed for the life of the press.
It is also the only way to fix low areas or corrosion damage on cylinders "in" the press. Bondo/JB weld will not hold up on this application and is not accurate enough. We can control the deposit within .0003" depending on the type of damage.
