I have only partial information on this format so take everything here with a large boulder of salt

This document outlines the little bit of the scitex NCT file format as I have been able to reverse engineer. This is not enough information to open a NCT file.

The scitex/creo/imation/kodak nct file format is a common file format used in the prepress industry. Nct files will almost always will contain either a CMYK, greyscale, or multichannel image. It’s major improvements over the ct format are the support for 16 bit channels and multichannel images (ie. PMS colors).

Common extentions are .nct

NOTE: All numbers are stored in the big endian byte order
