Multi-channel Export

Package every channel marked Export in the formats your RIP or screen room needs.

The Multi-channel Export section shows four checked output formats and the Export Channel Package button.
Multi-channel Export with all four formats selected: 1-bit TIFF separations, 8-bit Photoshop multi-channel TIFF, PSD spot channels and channel PNGs. Five generated channels are ready to export.

Turn on Output Channels, run Test Mask, then choose formats and select Export Channel Package.

FormatContents
1-bit TIFF separationsOne bitmap per channel. Every exported channel must be binary (0 or 255), including registered DTF/DTG white. Continuous-tone channels, including UV white with intermediate values, are refused.
8-bit Photoshop multi-channel TIFFAll channels in one TIFF with named channels.
PSD spot channelsA Photoshop document with named spot channels.
Channel PNGsOne grayscale PNG per channel.

Each package includes a manifest that follows the published manifest schema, with lossless checksums for every channel. Chromalith re-reads exported channels to confirm they are bit-identical.
