Palestinian banknotes and negative templates
How to print banknotes
Printing banknotes involves complex and precise steps. This process is attributed to skilled engineers and craftsmen who operate large printing presses for long and arduous hours to print paper money in large bundles. These bundles are then cut using a special machine resembling a guillotine and distributed to banks. Special papers made of cotton or other materials are used. polymer 
The printing process takes place in two stages:
1- Offset Printing: This is a process that takes place by using large printing machines to print the background image of the banknote on both sides, and through this process the security patterns found on the background of the banknote are printed.
2- Intaglio Printing: In this stage, the images and designs are printed on both sides of the paper.
To prepare for the intaglio printing process, a template with the banknote's design must be polished using a reverse or negative method. It appears that the method of printing Palestinian banknotes at that time used the traditional method of printing postcards at that time, as negative templates made of transparent acetate sheets have recently appeared in auction houses.

What is the significance of negative templates on Palestinian banknotes?
These are the only negative plates available for personal collection, as the rest of the collection is kept in the archives of the Zionist Bank of Israel. Therefore, it is a unique collection and is considered an important evidence of the printing technology used at that time in Palestinian banknotes. Also, printing has developed and the negative plates are polished on copper or zinc plates, so it is considered a primitive printing of banknotes in itself. Despite this, the collection was sold for a low price, less than the amounts expected by Spink Auction House.
