Producing exam papers using the Smart-binder
The Smart-binder is the premium saddle-binding solution for production of Examination booklets from digital printed sheets:
Typical Exam booklet production lines
More printing companies are using IBIS Smart-binders to produce exam booklets compared with any other digital finishing system. The reasons for this are as follows:
1/ Booklet security and integrity
The highest priorities for exam booklet production are security and page integrity. Security is needed to ensure that there is no breach of printed examination test data. Finishing in-line with the printer is often preferred because then printed sheets or rolls do not need to be stored prior to stitching: they are finished directly into booklets. Finished booklets are often immediately stacked, strapped and/or wrapped so that the printed data cannot be viewed by anyone until the pile bundles are unwrapped in the examination test location.
It is essential that no sheet can mistakenly end up in the wrong paper resulting in one student with a page missing and another with an additional incorrect page - not the best start for a successful exam result for those individuals!
For this reason the Smart-binder has a fully integrated sheet detection and tracking system (using a bar code printed on each sheet) to ensure the integrity of each finished booklet. If there is any risk that a booklet could have incorrect pages, or the correct pages in the wrong sequence, then it is automatically rejected.

2/ High reliability with minimum maintenance
Machine 'availability' (up-time) is important in a high volume exam booklet production environment, particularly when operating in-line with a digital web printer. The Smart-binder is a very heavy-duty system designed to operate 24/7 with the minimum of maintenance and with the highest possibility reliability. Some IBIS Smart-binders have produced over 70 million examination test booklets.
3/ High speed output
Exam booklets normally contain a small number of pages which means a high cycling rate if running inline with a high speed digital printer. The Smart-binder can therefore run constantly at web speeds around 100- 150 meters/minute and typically producing around 7,000 A4 booklets/hour when making 8 - 16 page booklets
4/ Stacking, strapping, wrapping and labelling
The optional booklet stacker BSS-10 is often used when making examination
booklets when they contain a small number of pages because of the resulting
high production and also because it is desirable to reduce the number
of operator contact points and the number of opportunities for the printed
data to be visible.
BSS-10 book stacker
For this latter reason the stacked booklet piles are often then immediately
in-line strapped (to avoid the booklets being removed and opened) and
also sometimes fully wrapped. Printed labels may need to be added at this
stage to identify the school and/or the specific exam for which the booklet
stack is intended.
5/ Variable page extents
Sometimes the run lengths for exam papers can be very low, even though the daily volumes can be very high. e.g. 1 million exam paper booklets a month from each Smart-binder. The Smart-binder can change the number of pages 'on-the-run' under bar-code control, while maintaining the integrity in each individual booklet (correct pages in the correct sequence).
6/ Cover matching
A separately-printed cover sheet, if needed, may be fed from the optional Smart-binder cover feeder. If personalized then the cover may be bar coded so the Smart-binder can ensure it is correct one for the booklet to which it is attached (note: examination test booklet do not normally require a separately fed outside cover sheet).
7/ Document personalization, question shuffling and booklet tracking/reprint
Exam papers may be personalized and may include the student's name. Consecutive papers may include the same questions but in a different sequence to reduce risk of the student copying from their neighbor during the exam process. This is sometimes called 'question shuffling'.
Data tracking is often essential in order to know exactly which exam booklets have been produced and to allow any missing/rejected booklets to be reprinted. The Smart-binder includes a sophisticated tracking system using Bar code (or Datamatrix) code readers and sensors. The Smart-binder control PC retains log files containing production data relating to each booklet that has been produced or rejected. The production log files may be viewed externally with a network connection if required. The optional SDA-100 Smart-Data Analysis system assists with the upstream interface to enable automatic reprinting of any missing booklets
8/ Answer sheets and automated marking
Exam question booklets may sometimes need to include an 'answer sheet' on which the student provides an answer to each question during the exam. The Smart-binder can produce a booklet which contains both the questions and the answer sheet. The answer sheet may be printed together with the question sheets in which case it may receive a line of perforation from the option DMP-100 dynamic perforator to allow it to be easily detached from the question booklet.
Alternatively, the answer sheet may be separately printed and loose -inserted into the finished question booklet . Automatic 'matching' is then provided to ensure that each booklet contains the correct answer sheet
Automatic 'marking' of completed 'multiple choice' examinations may require the spine of the booklet to be slit off so that the pages can then be fed individually thought an automatic marking machine. Alternatively it may be the completed multiple-choice answer sheet itself which is removed from the booklet for processing by the marking machine.
9/ Wire stitching or ISG cold gluing
IBIS's unique and patented ISG cold glue system provides a higher quality
binding alternative to wire stitching. This results in improved booklet
lay-flat which can help subsequent inserting and mailing operations.

Each of the following customers are using the IBIS Smart-binder exclusively to produce exam test booklets:
Case study 1: UK
In 2008 this customer purchased the first 6 IBIS Smart-binders for exam paper production. 3 were installed in-line with cut-sheet printers and 3 in-line with web toner printers. Since then the Smart-binders fed from the web printers have each produced over 60 million booklets. In 2014 this customer ordered two more Smartbinders which were installed in-line with ink-jet web printers and in 2015 two further in-line Smart-binders were installed.
Case study 2: Japan
In 2006 the large Japanese printer 'TF' ordered from us their first Smart-binder systems to produce examination test papers for Japanese students. These machines operate 'off-line' using high- pile sheet feeders which are fed from color-printed sheets using a loading trolley system. During the period 2006 - 2010 IBIS installed a total of 9 Smart-binders at this site in Tokyo, all of which are used to produce exam test papers of variable thickness and with dynamic sheet perforation. All exam booklets produced by TF are bound using the Smart-binder's unique ISG cold-glue system instead of being wire stitched. Every booklet has separately-fed cover sheet which is personalized and 'matched' to the inside sheets.
Case Study 3 USA
This customer near Minneapolis has special requirements for finishing exam test booklets in-line with ink-jet web printers and uses three 'customized' Smart-binders for this purpose.
Case Study 4: Africa
Over the last 5 years, a number of IBIS Smart-binders have been installed at customer sites in Tanzania, Malawi, S. Africa and Zimbabwe to produce exam test booklet in-line with web printers. We are finding increasingly that countries such as these which in the past have chosen to have their exam papers produced in other countries (such as in the UK) are now preferring to bring production back to their own country. The extra security resulting from Digital Web printing with in-line IBIS finishing (Smart-binders) is contributing to this change.
