Hello Cornish, The PDF is from the M.A.N press manual, a challenge for you, find any modern printing
presses that move the impression cylinder, if you do - I will enter a Cornish Pasty eating competition!

Hello SheetSQ.
Clarification again! the Blanket cylinder adjustment moves toward or away from the Impression Cylinder
which does not have Bearers!
Regards, Alois
The press is in a "Disgraceful state" --- El Hilal, you need some tuition on printing!
Even the Cylinder Bearers are in a bad state - the "Case Harding of the Steel shows signs of DAMAGE.
Regards, Alois
Hello, chriscozi and SheetSq.
I agree - use the "Grid Test"
Clarification re Printing Press Cylinder Config. - The Impression Cyl. on most modern Presses run in FIXED Bearings any
adjustment is set via the Blanket Cyl !!!
Also, have a qualified Press Engineer - Check the Backlash...
Hello Steve, thank you, couldn't see the wood for the Trees !!! - I'm getting better all the time with the
benefit of all the "Sages of the Printing Industry"

Gentlemen,
In simple terms, the Pressroom requires the Pre-press to produce " Production Compliant Image Reproduction" be it Halftone/Text or Solids.
Pondering: GB?

Hello Bashv,
The 4 Colour page needs "Tone Reproduction Curves for U/coated Paper also the Mono (B/W pages)
Why are you printing the 4Col on U/coated Paper?
Regards, Alois
Gentlemen and fellow Lithography
Explainer - There is competition for Metal Surfaces in Lithography between Ink(Fatty Acids) and Desensitization (Fluids) Gum Arabic/ FS Concentrates etc. Fatty Acids (Ink) usually win because they have stronger Molecular bonds than weaker Desensitization...
Hello Bashv,
Question - are the pages a mixture of B/W and 4 colour images on the same page?
2) How many pages in total eg. 12/16/24 or 32 pages?
Regards, Alois
