We have been having the problem of getting half circle marks about 3/4 back on sheet from gripper, 19x25 sheet, Heidelberg 72SP, mostly on 2nd unit, cyan, and they tell me its the sucker feet that hold the sheet in place with vacuum and that spray powder on these feet builds up, transfers to blanket and then over time makes a low spot in the blanket and voila, the half circle marks show up. The cure is to change the blanket.
My question is there a way to avoid this or make it longer between changes? Like cleaning those feet when blankets get cleaned or anything like that? They say no cause its just powder that's on the sheets and in the system and it wouldn't help? I've no experience on press and just looking for any info that may be helpful for them.
Thanks
