We undertake the redesign and editing of books made in our electronic format, but we also undertake the processing of books, documents and archival materials made in other electronic books. In the latter case, written permission from the right holder of the publication is required to complete the work in order to avoid further disputes. (There is no need for companies to process their own internal materials.) More and more companies are seeing fantasy in their digital document processing, which significantly shortens data retrieval and, if necessary, paper-based reproduction. There are several possible ways and formats of these archives. We look for the most economical solution for concrete cases.
