The published articles are meant to primarily educate the students in printing to supplement their knowledge in the field of Printing. These are not simple Glossary of printing terms, but to the extent possible every term has been explained in brief so that it can be of some use to the students who appear in some sort of examinations and interviews.
I served the Printing Industry for over 40 years
in various capacities, a major part in an Security Printing Organization. In order not to waste the printing and paper related knowledge which I gained over years, I decided to keep them in public domain for the reason stated in prepara. Most of the illustrations - over 90% - have been generated by me to explain the terms suitably.
While I am not sure to what extent the published content will help, if the content is going to be of use to some one in some manner, I will be greatly satisfied.
Your views may be sent to me ( for my record and correction wherever needed.

features of the special device for sequential numbering -2

One of the features of the
special device for sequential
numbering of sheets


Of late concern has been raised over the menace of forged bank notes and currencies all over the world. In order to strengthen the security one should not concentrate on the design aspect alone. Some different thinking is needed. Few ideas emerges in the direction of the numbering systems. They are shown below:

Over the years we have been numbering the documents only with a set of standard fonts and letters without realizing that some security can be added to them in addition to the style of font the specially prepared numerals can also have some designs which can not be copied by the counterfeiters. How could this be done ? With the special device (numbering box) it can be done.

We are using the conventional numbers so far which are of plain text as shown below.


However in the suggested number each numerals will have a specific design element in it. Say No 1 will have a design which will be different than No 2. The No 2 different than No 3 and so on.

Either the designed number panel can remain on the top or at the bottom in the manner suggested . The design element can also be country specific so that the cost of reproducing them will become very high to the counterfeiters as such Numbering boxes will not be available. More over it will remain an overt feature for the Public. Both the two Numbering boxes will have to be engraved with such Numerals. 

The numbers can be printed with specific shades as per the design element content in it. The numbers can also be printed alternately with colour changing ink which will alter the shade as shown above even with touch of finger which will have minimum body heat. The counterfeiters will not be able to produce such a numerical wheel which will be very costly.

This is one of the advantage of the device patented as registration will be highly difficult for counterfeiters to register the numbers besides it is non photo copyable as the color copied print will not change the color of ink with body heat from  the finger .
