    Interesting. I used to run sheet-fed presses, but this is the first time I've had any insight into the web process.

    Everything looks soo clean, when doing a plate changes I could get ink up to my arm pits .
    Alot of jobs have been lost in printing in the last 20 years which is a real shame as they were very well-paying jobs.

    When setting four colours regarding magazine work it’s important a tradesman can initially determine coulor properly to change what primary ink needed to increase or decrease.The giving the ink duct time to process changes is also important.

    Fascinating! How do you print things with more than 16 pages? Multiple press runs and binding them all together? Or multiple presses?

      Good question. Both of your suggestions are done by different printers with different amounts of equipment. Plus, there are presses with capacity for more than 16 pages. I visited Brown Printing in Minnesota in the mid 1970s. They were in the process of building a press that could print 96 pages in one pass, based on a contract they entered into with _Newsweek_ Magazine. On the other end of the spectrum, I ran a sheet-fed offset press that produced 8 pages -4 on one side of the sheet, four on the back side. I had to put the sheets through the press twice, one for each side. Separately, in the bindery, they were folded into signatures and saddle stitched together to make catalogs, high school sports programs, etc. The presses with large page counts probably run multiple webs at one time, as do newspaper presses, also. The webs are threaded into the folder after they are printed. I'm retired now, but I still enjoy ink on paper!

      @@Mxsmanic How in the world did anyone hold a newspaper that thick in their hands to read it? Do you have particulars about that issue? When was it? Why so may pages, etc.? Thanks.

      I just found it on Google. It says it was a Sunday issue in 1987. Very often newspapers print Sunday sections (such as Travel, Fashion, Food, Theater, etc.) in advance, during the preceding week. Then they are stored, and inserted into the main paper. That must have been a back-breaker for the carriers on that Sunday!

      @@kenschwentker4446 Those were the days. I like ink on paper because it doesn't jump around when you try to read it, and advertisements don't blink into existence right in front of it.

    Those festoons are in an odd spot, and it looks so enclosed. Not great to work on.

      Is that a Butler splicer? A Letterflex(Cameron) Press I operated for 12+ years had a Butler that worked very well. The narrow web Offset webs there also had Butlers.
