DTF Glossary
BigTIFF
BigTIFF is a TIFF extension that replaces ClassicTIFF’s 32-bit file offsets with 64-bit offsets so the container can address larger data structures. It solves an offset boundary, not every large-file problem: decoded raster memory, pixel dimensions, channel count, application limits, and RIP support remain separate constraints.
In practice
A “.tif” extension does not reveal whether a file is ClassicTIFF or BigTIFF. The writer and every reader in the handoff must agree on the variant; otherwise a technically valid file can still be rejected.
NestSheet’s Production DTF preset export uses a classic TIFF with CMYK and one W1 white channel at 300 dpi. Keep sheet dimensions and the receiving MainTOP queue in the job record, and check the actual production file before a long run.
