+ * As the purpose of this program is to allow fine grained control over
+ * the output, it uses the raw CMYK output type. This feeds 16 bits each
+ * of CMYK to the driver. This mode performs no correction on the data;
+ * it passes it directly to the dither engine, performing no color,
+ * density, gamma, etc. correction. Most programs will use one of the
+ * other modes (RGB, density and gamma corrected 8-bit CMYK, grayscale, or
+ * black and white).
