Booklet cylinder numbers
Hi all,
I have just been checking through our booklet panes and came across these two cylinder panes.
Following threads and e-mails over the last couple of months has shown me just how ignorant I am about basic printing processes.
I should imagine a guided tour of Harrisons or similar firm would set things right in my head,
but that aint going to happen. Being security printers it is also unlikely that they would issue a nice user friendly 'how to' dvd.
Regarding the cylinder numbers on booklet sheets, are they replaceable like the dates on modern handstamps?
In these examples the 3 on the left looks to have a straight line at the top right and on the F the serifs are different .
Can anyone fill me in on details of these please.
Regards to all
Ron
