: Black and white printing I have some problems printing rich black, and I´ve spent days trying to find a solution on the internet, but there is just too much information... I´d happily spend

@Shelley591

After some quick googling, I found this:

It appears that an ideal process for printing B/W on this printer is to use their special UltraChrome K3TM Ink Technology which includes three-levels of black inks. You'd use these specific inks in you printer.

Again, though, this is less of a Graphic Design question and much more a photography question. I'd suggest you migrate it to the photography SE site to get some insights from actual photographers who make their own prints.

My guess is that you copy the greyscale image, create an new CMYK image, paste the greyscale into each channel, and then adjust the curves on the CM and Y channels.

If I were you, I would talk about this with your printer: they may have experience coverting greyscale images for this purpose.

Note that flooding the page with nearly 100% of all inks can be a problem depending on circumstance and paper choice. I know that "painting a sheet" can cause issues (color cast etc) for other pages on the form in-line.

Having your file in CMYK is your best bet, I'd say. You can check whether your adjustment layer yields rich black by 'stamping' a copy of all visible layers (select your topmost visible layer and press Shift+Ctrl+Alt+E) and use the eyedropper to check the CMYK values. If there's just black, then it's a poor black/grey, if there's also C, M and Y, it's a rich one.

For the actual printing process, I'd second @vector 's suggestion by doing a few tries of a smaller area, to save both time and ink, and compare the results.
