Thanks a lot for your reply. But sadly I am printing from Photoshop and the Text is RGB 000000
I tried from PS, Word, Indesign, even from the Text Editor. I can't get a real deep black.
Keep the testing within boundaries, so printing from Photoshop only. An RGB text + logo, both RGB 000, as an image file Jpeg, Tiff, printed through the same pipeline (same; image color space assigned, driver mode, media preset, print resolution, profile rendering, paper, paper side) gives another black than a photo as Jpeg, Tiff and with RGB 000 black? Some logic missing there. Other papers, other media presets, other print resolutions, other profile renderings may give another black Dmax, the first being the most important factor.
