View Full Version : Bottling Standards w/ Preps for Textbook Work?

08-01-2007, 02:08 PM
We are primarily a textbook company that produces MANY products on a daily basis. We have established set standards for our shingling/creep depending on thickness of paper and no. of pages in a signature as well as the differences between saddlestitch and perfect bound books.

We are looking to establish similar standards for bottling. With the research we have done it appears that .5 degrees seems to be what most shops are using. From the testing we have done, we have seen better results when we are NOT using a consistent number on the various middle pages on our templates.

Does anyone have some guidelines or magic formula they are using based on paper weight and signature size that they would be willing to share?

wouldn't that be press and stock specific? We ran test after test to make those numbers and i would be really afraid to use someones elses numbers. - tc

You are correct. It is not only press / paper specific, it is also affected by the bindery equipment and changes outside our control. At this point we are looking to apply it to only books that are very obvious due to the image area being closer to the trim, and for specific clients.

It is a very labor intensive process for an imposition operator since you have to apply the bottling angles on each page you want to be skewed. Applying the shingling/creep is a no-brainer in comparision.

It would be wonderful if Preps had a way to apply "smart bottling" like it does "smart marks" that could be saved and applied to templates (32 PG SIG/48 PG / 64 PG) and shops could categorize them by press/paper, etc. (Some competing imposition softwares can do this.)

Thanks for confirming my thoughts.

We use .5 degree on the middle 32 pages of a 64 page sig for 30# newsprint. It's a far from perfect system. Ideally you would be able to set the maximum creep in the middle of the book and have Preps calculate it at lessening values as it goes towards the outside....just like shingling, which you've already stated.
