1) What is a
Back Gate Margin?

1) The Back Gate Margin is the distance from the edge of the paper on the bind edge to the inside or beginning of the punched hole where no live copy can be placed. In designing a book for mechanical binding, allowance must be made in the gutter (inner margin) of the book for the punched holes. See Illustration

3) What is the Book “Bulk” and how does that affect
my quote?
3) The degree of thickness of paper. In book printing, the number of pages per inch (PPI) for a given basis weight is the foundation to accurately calculate the bulk of your book to be bound. Our quotes and time estimates will increase proportionately as the bulk increases.
4) What information
is required of a
new customer?
4) All new customers will be required to complete a credit application and Wisconsin Resale Certificate (Tax Exempt Certificate).
We would also highly encourage a plant tour for new customers to learn first-hand what a partnership with Binding Edge may include. (Back to top)
5) Why is a sample necessary to begin any binding project? 5) A sample of the exact manufacturing process required of the bindery is crucial before any job begins to assure that all final size measurements and Back Gate margins are strictly followed. The sample will also be representative of tab placement, special inserts, or any other production notes that need to be addressed up front. It is extremely important to make sure that the sample or prototype provided is produced with the exact paper stock that will be used for the “live job". By confirming the stock type, the bindery can properly plan for the necessary pitch and hole punch configuration, and also order the necessary binding elements well in advance of the production date. Note: Any materials that are provided different than the original sample may result in an adjustment to the original quote. (Back to top)
6) Can books that have
tabs inserted be punched automatically?
6) The only way this is possible is if the book has a 1/4” shoulder at the head and foot (top & bottom) of the book. This allows the punching equipment the necessary margin to properly push the books into the machine die block. Any supplied book outside this spec would require manual hand punching. (Back to top)
7)Purchase Orders and Subsequent Changes 7) The Binding Edge will not schedule the commencement of an order until we have received a complete purchase order from our client that includesdetailed instructions, pricing that is cross referenced to the Binding Edge quote number, and the signature from an authorized company representative. We are aware that changes may need to be made during the execution of a project. In such cases we require a revised purchase order reflecting those changes to protect both parties and minimize the opportunity for errors in the early stages of production.In the event that a client chooses not to use a purchase order we request full and detailed instructions on company letterhead, complete with the signature of an authorized representative. Any changes to these instructions must be documented in writing and be provided via fax to the Binding Edge, and must be followed up with revised, full and complete instructions toreplace the initial set (on letterhead, with authorized signature.)
(Back to top)
8)Samples 8) Samples from our clients are often necessary in communicating their desired
end product. When sending signatures, sheets and components that are to be
used as samples, please mark them clearly as such. Please separate sample
materials on their own pallet, and when possible, provide approved composite
samples as a guide for consistency. (Back to top)
9)Dry Ink 9) The importance of dry ink cannot be stressed enough. Visual alterations occur through normal bindery operations because each sheet is processed in some way. To avoid excessive markings caused by semi-dry ink, make sure that your press has qualified the ink as completely dry before shipping material to the Binding Edge, paying special attention to large areas of solid ink, dark colors, reflex blue and other specialty inks that typically require extended drying time. We will conduct basic tests to ensure the dryness of the ink, unfortunately these tests often times cannot be conducted until later than we would like in the binding process. (Back to top)

11)Product Leftovers 11) Our customer service team will be happy to discuss with you what you would
prefer to have done with leftover pre-bound materials. The Binding Edge will
gladly hold remaining stock for your future use (please ask about warehouse
pricing), or we can ship leftovers back to you with your end product. (Back to top)
12)Challenging Paper Stock

12) The Binding Edge takes great pride in meeting and exceeding industry standards, which includes the handling of extraordinary papers. In order to serve our clients best, we ask that samples be sent beforehand, especially when unique paper is involved, so that we may run tests to identify possible irregularities that may require a percentage more pre-processed materials to account for problems. The following are paper stocks which may require extra
attention:

  • Papers coated on both sides cause irregularities in the automated punch process due to slipping; this will slow the process and often require hand punching and inserting the page later in the process.
  • Matt or dull finishes cannot be automatically punched because of the possibility of scratching. These too will be hand punched and inserted.
  • Heavy stock often presents challenges and will be treated in a similar fashion.
  • Curled paper slows down the collating process, punching process and folding. Please make sure your provider packages papers according to their specific qualities. Please also take paper qualities into consideration whenpackaging material for shipping to the Binding Edge. (Back to top)
13)Proper Signature Identification 13) Signatures should be marked on the fold with numbered blocks which appear as a stepped pattern when signatures are stacked in their proper order. Different versions should be labeled separately. It will help greatly if signatures are shipped separately and are each
marked with a load flag. (Back to top)
14)Signature Folding 14) Please be sure that folding of signatures is accurate. Signatures must be perforated at the folds to let air escape during trimming and a minimum of 1/4" trim on all 4 sides is needed. Non-perforated signatures require us to trim in much shorter stacks, which greatly reduces efficiency. (Back to top)
15)Cutting

15) Cutting 

  • We require specific cutting instructions for each job. Sending a finished sample to illustrate these instructions is often recommended. This is especially important with horizontal alignment bleeds, which requires more individual attention to the cutting process.
  • Marked press sheets are required if we are to cut signatures to requested dimensions. Allow plenty of gutter/bleed around live print to allow for variances in the trimming process.
  • The Binding Edge is not able to cut laminated pages when the lamination exceeds 1/2 mil. If any other material will be used that would not be considered normal such as embossed, die cut, hot stamped or UV coated stock, please let us know.
  • If the Binding Edge is to trim covers with the signatures after collating, covers should be shipped in the same size as the signatures.
  • If book-blocks are provided, they must be perfectly square to avoid misaligned print, margins, trim edges and the need for hand punching.
  • Check with the Binding Edge before printing a project to ensure that the length will not result in a half-hole punch at the head or foot of the book. (Back to top)
16)Cover Layouts 16) Additional handling can be prevented with a cover in press sheet form (multiple up). Please be sure the layout allows enough gutter for the covers to be trimmed to size and collated with the signatures. (Back to top)
17)Mylar Reinforced Bind Edge 17) Mylar reinforcement is applied with glue, and for that reason a Mylar reinforced bind edge cannot be automatically punched and will require hand punching. Please provide samples if a Mylar reinforced edge will present this problem in the job you are sending.
(Back to top)
18)Handling of Vinyl Sleeves and Pockets 18) Vinyl or plastic material will adhere to itself along the edges, and temperature extremes can cause stacks to become misshapen. Request that your provider place dividers between short stacks of these materials. Both vinyl sleeves and pockets require special handling and will be hand punched and inserted later in the binding process. (Back to top)
19)Customer supplied perfect bound book and Binding Edge to trim spine.

19) Customer supplied perfect bound book and Binding Edge to trim spine.

  • Cover can be bound on book.
  • We would take 2 cuts — first cut 1/8” and second cut 1/8” to remove all spine glue.
  • Backgate needs to be figured for final size once the books are trimmed — ie, if final size is 6” x 9” the book dimension requirement is 6-½” x 9” and the backgate should be figured from the 6” dimension — not the 6-¼” dimension.
  • No side glue — only a light glue to hold covers and signatures together. (Back to top)
20)Shipping and Packaging of Materials

20) All incoming pre-bound materials must reference the quote number from the Binding Edge on both the purchase order and the paperwork. Necessary precautions must be taken to avoid damage to materials while in transit. The Binding Edge would strongly recommend the following:

  • Skids prepared with corner boards, stretch film and metal banding in four separate locations on the load.
  • Materials with UV coating or film laminating require additional security such as corrugated siding, covering every side of the load.
  • Materials such as loose books require additional support so that the loadwill not shift in transit. We would recommend a topper on these types ofloads.
  • When stretch wrap is applied, make sure that coverage extends below the bottom of the load to ensure product will not shift or slide out from between the load and the pallet.
  • Packed cartons must not have any unused space inside. If the carton is not filled with materials, packaging material should be used to fill remaining areas.
  • Mechanically bound books must be staggered (wire left, wire right) to prevent indentations, scratching or damage to the binding itself.
  • Tabs and other pages with irregular edges should be packaged bind edge down.

All cartons should be clearly marked with count and title information. When
materials are shipped on skids, we require a complete and clear load flag
with all necessary information, including an accurate count. Discrepancies
in the count do occur between our clients sending and our receiving the
material; we will therefore confirm the count upon receiving the materials. (Back to top)

21)Grommets 21) When shipping a job that includes pages with grommets, stack pages insmaller quantities and use slip-sheets to prevent the pages above placing weight on the grommets and marking the pages below. (Back to top)
22)Extending Index Tabs 22) Pages with extended index tabs are especially susceptible to damage during shipping. Packaging these pages with the tabs facing up and the bind edge down is often the best solution.We require 1/4" margin between the tab and the top (head) or bottom (foot) corner of a page for automatic punching. If the tabs are flush to the top (head) and bottom (foot) the project will require manual hand punching. (Back to top)
23)Varying Sheet Sizes 23) We request that sheets of different sizes are sent separately along with a sample composite whenever various sheet sizes will be put together. Swatch-books will be collated, different stocks padded together, and trimmed to size before being bound. (Back to top)
24)Oversized Covers 24) Make sure that oversized covers are packaged in such a way that they will not be damaged in transit. Shipping these covers separately is often the best solution. Covers that are larger than the book-block must be punched separately and added later in the binding process.
(Back to top)
25)Pricing and Time Amendments 25) During the course of a job it occasionally happens that unexpected obstacles are presented such as the need for hand punching/inserting, the discovery of damaged materials, an incorrect labeling of materials or inaccurate instructions and composite samples. These types of errors will effect pricing of the project, as it will force the Binding Edge to invest more time than previously estimated. Clients with questions regarding changes or any requirements in the faqs section of the website should contact Russ Brown at ext. 203 or Sara Gerndt
at ext. 236. (Back to top)
