Jet Letter PSL is
Industrial Strength variable data printing software product designed from the ground up for direct mail marketing firms and anyone wanting to print high volume personalized printed products. Jet Letter users range from small direct mail shops printing 100,000 marketing pieces a month to large financial and health care firms printing millions of transactional pieces a week.
Jet Letter is used by over 500 direct mail firms just in the United States.
The features and benefits of Jet Letter PSL are the result of 15 years of product development in one industry – variable data printing for direct mail. Applications ranging from simple name and address and a few variables on (n-up) marketing postcards to the most complicated transactional (and trans-promotional) applications.
Jet Letter PSL is the sort of technology that forms the foundation for a business – the competitive edge that results in growth. Many firms will attest (link to testimonials) to that. Part of the reason for that is that it is a scripting language. The other part of that is that it is a very good one. It’s good simply because we listen to our customers and improve the product on an (almost) daily basis. A scripting language means that YOU have complete control of how a document appears -- you don’t get what a programmer thought you might want when you clicked a radio button.
In Jet Letter PSL there are over 750 commands available (link to language spec) – No, you don’t need to learn any more of them than you need – but they are there!!! It’s the minute attention to detail that we deliver in Jet Letter PSL that you can use to deliver that so important attention to detail in the printed piece.
We have yet to find a project we could not do.
That simply can not be said of any drag ’n drop product. For example, we had a client who needed to print booklets ranging in page count from 16 to 32 pages as there were variable sized tables involved. Obviously imposition was required and the client planned to do such imposition manually after the PDF production. Seeing a need to be filled, we wrote an imposition routine that handled imposition for variable size booklets during production of the PDFs. Combine that with stitching controls on the fly and we now have such functionality in our product for everybody to use. That’s what Jet Letter PSL is – the software firm that listens AND responds. When we find a need we fill it!!!!
Another example of what Jet Letter PSL is – and how it listens is the help system, and other superb training aids built into the product – not off in some arcane website. When you see a command you don’t understand a right click on it and the system takes you to a description of it, and a click on the "Example" button gives you examples of how that command might be used.
Lastly, it’s fast – merge speeds in the range of 30,000 records a minute. More...
