I have a client who wants designs that are available in color and grayscale 24x36 as PDF.
Sounds pretty simple but I cannot get the grayscale version really sharp so the text is clear.
I have Photoshop essentials (not Pro) and Acrobat.
I have discarded the idea of using JPEG anywhere because of the lossiness. I have a perfect result exporting as PDF at 300dpi, opening that in Photoshop, converting to grayscale and saving as GIF and creating a PDF. Except that makes a file that thinks it is 150" x 100".
If I export as PNG I get fuzziness. TIFF has strange tonal effects. Any help would be welcome
