Congratulations to your daughters wedding.
Now for your problem, I understood the following:
You have a PDF of 190 pages and you want doing the bindings yourself.
I normally send that to a service provider, who does all the hard work for me, but if I would need to do it myself, I would proceed as follows:
In the "Pages to print" you need to select the bindings, using a multiple of 4. In addition, the bindings should be the same size (i.e. having the same amount of sheets. You need to decide how many sheets you can handle per signature (because that's basically the reason for using signatures).
Your 190 pages will lead you to 47.5 sheets which will be 48 sheets (2 blanc pages). 48 sheets may be separated in 8 signatures à 6 sheets. You can probably handle that quite easily. Other possibility: 3 signatures à 16 sheets, 4 à 12, 6 à 8 etc.
First signature will be 1-24 pages to print, second 25-48, ...
I hope this helps. Good luck.
Thank you Abambo! I will give this a shot later today! And thank you for acknowledging my daughters wedding. It was beautiful!
Mission accomplished and now I understand how all this work! Will take this info forward in life with me. Thank you for giving me a guru moment!
