We are here to help - after all, print production can be a
demanding and complex world. At The Lettershop Group we have the
experience and expertise to help guide you through. This section of
the site is designed to do just that - and we will continue to
expand and add useful information.
To help navigate your way through the complexity of terms used
in the print production industry, we have developed a truly
comprehensive Glossary of terms that will help you tell your
friction feeder from your form rollers and your IPH from your ink
density. It's all here...
