In PDF24 Creator, Tools>Output profiles> PDF general tab, Only RGB, CMYK and GREY are the options available in the tab 'colour Model'. As we are using Black&white(1bit) TIFF files for creating PDF documents, we would like to have the option for B/W also in the tab 'colour model'. Otherwise the file size of the final PDF created is too large. Pls suggest a solution to get the PDF output file also in black & White. (we have enabled PDF/A1 mode)
