We currently receive "problem PDFs" where either the CMYK ink levels are too high or, most commonly, the PDF is RGB and when we convert to CMYK, the TAC is too high. This is not really an issue where files are going to a digital machine, but is for litho, especially uncoated stocks.
I know that Gray Component Replacement (GCR) and Under Color Removal (UCR) are techniques that can reduce TAC, but I can only find tools costing tens of thousands of dollars (i.e. Alwan) to achieve this.
Am I missing a trick here? I'd like to "fix" customer's PDFs, not just reject (for example) MS Publisher created files. Can anyone point me in the right direction for researching a solution?
