The given test file uses both PDF 1.4 transparency (soft masks) and spot colors. PDF 1.4 transparency compositing currently uses either an RGB or a CMYK process color model. As a result when doing PDF 1.4 transparency compositing, the spot colors are converted using the color space's tint transform function. To properly support spot colors with PDF 1.4 transparency features, the process color model for the PDF 1.4 conpositor needs to be extened to support spot colors. (A sub task of this enhancement is to determine the number of spot colors prior to the main processing of page. This is needed so that buffer space can be allocated and to limit processing time. Determining the number of spot colors is probably practical for a PDF file but not for a PS file. Fortunately transparency compositing is only a feature of PDF and not PostScript.)
