Sm52-2 straight 3 marks are ok the 4 is not ok

Hello, sorry for my English. I want to buy an sm52 2 color 2000. In the testing of the machine, when printing the 2 color 3 marks are ok but the 4 is shifted 0.5mm or plus.
And when I set pression the 2 unit is printing just the half on the sheet, in the blanket is full.

Thanks for your help

 

good evening dear sir, your machine is a sm52-2 or sm52-4. Please make sure to see if the plate cylinder and the blanket cylinder are properly adjusted. And see drive side C.E

 

Thank you for your answer, the machine is sm52-2

 

could show us some picture of the impression you made.

 

Make sure that you've got the correct packing under the blankets and that none of the packing sheets got folded when installed.
