EPS export wrote every gradient with a spot color stop in process colors. A gradient of tints of one spot color and paper white is now written in that ink's Separation space, at Level 2 and 3. At Level 3, a gradient that mixes a spot color with CMYK or gray colors, or two spot colors, is written in a DeviceN space of the process inks its stops use and the spot inks, each spot ink with the CMYK equivalent its Separation space has. An off-center midpoint is a stop with the inks halfway between its two stops. Paper white is an exact white, whether or not the stop is linked to a process swatch. These gradients are still written in process colors, each with its own warning: a mix with other inks at Level 2; a mix with RGB or Lab colors in an RGB export (a CMYK export converts those stops to CMYK first); a DeviceN space that would need more than 32 colorants or a spot ink named Cyan, Magenta, Yellow, Black, All or None; and a Perceptual gradient. The old warning for every spot gradient has been removed. The header lists two or more spot colors with each %%+ line right after the comment it continues: %%DocumentCustomColors and %%CMYKCustomColor were interleaved, so a DSC reader took the second ink's name as part of the first ink's %%CMYKCustomColor.
