We aim to get print quality pdfs from TCPDF and been using SetTextColor with CMYK values when creating Text.
However, when we view the final PDF via Acrobat Pro > Tools > Print Production > Output Preview, select to show only CMYK and then take away black we expect the text to be removed as this was set at 0,0,0,100. However the PDF seems to be overprinting the colours so when you only show one colour at a time (Cyan eg) the text is still visible.
Any help would be much appreciated.
