Claim One:
1. A computer system running a preprocessor program that is implemented on a computer usable medium having computer readable code for preparing a document for proofing of spot colors, the computer readable code causing the following steps to occur comprising: accessing a spot color space in the document automatically with the computer system; using the computer system to automatically determine whether or not multiple spot colors are mixed together; determining whether the color space is a separation space or a DeviceN space automatically with the computer system; replacing an alternate color representation for said separation space if the color space is a separation space with a device independent alternate color representation as a new transform automatically with the computer system; using the computer system to automatically describe the multiple spot colors based on the DeviceN color space if the multiple spot colors are mixed together; applying the new transform to tint levels in the document, modifying the tint levels in the DeviceN color space so that spot color channels are sent to correct corresponding color channels in the device independent alternate color representation, and reconverting the new transform into proofer machine signals as a proofer profile automatically with the computer system; and combining the new transform and the proofer profile to produce a composite transform that is applied to image data automatically with the computer system to generate machine signals for operating the proofer.
