How do I get pure b/w in my prints and no colour tinge?

[Argee]

I import all my colour images into Lightroom 4 and then use Photoshop to convert to b/w and process final printing through Lightroom 4 to my Epson Stylus 360 Photo printer. However I find that I get a variation in my mono prints with a very slight colour hue showing in certain areas particularly where I have digitally modified. I understand that to get pure b/w from my 6 colour printer is difficult but ask if there is something I can do to achieve more accurate mono colour without these slight tinges. I always use the printer colour management so should I be using alternative colour management? In the Lightroom profile management list there are many setting choices, Adobe etc, and I don't know which one to go for. Also is it best to just reduce saturation instead of using the Photoshop b/w conversion to b/w? Any advice appreciated. Thanks in advance.

Why not use LIghtroom 4to convert to B/W? That's what I do. There's a button you click on, it converts and then you can change contrast, highlights etc.

There should be a Grayscale checkbox in the Advanced page of the Epson Printer Properties dialog. Tick that & it should only use the black cartridge.

When you have edited in photoshop and go to print, let photoshop manage colour, select the right paper profile and then when you get to the printer dialogue then select the correct paper type then turn off colour management (not sure with your printer, possibly check no colour adjustment) and away you go. One of the most common mistakes when getting a colour cast is double profiling (having both PS and printer managing colour) Grayscale isnt really the way to go as it will restrict tones.
