Started getting a few complaints that black images are dark green. As always I check everything before it goes out the door so I'm very surprised. I can only assume my lighting isn't showing the proper colours or blacks are changing into green when product leaves me!

I'm using Inktec inks through my Epson 1500W printer. All profiled and everything else looks as good as always. I've not ruled out issues with the artwork files and I still feel this could be where the problems lie. One customer sends me 72dpi jpeg files which are huge, I copy it into a template and re-save at the correct size. The file is RGB but when I check the black used the RGB values are all zero and the CMYK values reflect a true black.

Even after all this time I still find profiles and colour values confusing so happy to accept it could be me! lol.

Sorry to be the first to respond to my own thread! lol.

I'm working through everything. Just out of interest I took the customers black image into Photoshop and used the convert to profile option, choosing my printer profile as the destination space. The black immediately lightened and when I checked the value it is showing as dark green now! I've never used this feature so may be misunderstanding what it does but seems interesting?

If you are printing in Photoshop, you may want to try checking the "black point compensation" tick box in the printer dialogue. As I understand it, this should ensure that a pure black in the original file is rendered as a pure black in the final output.

Its probably worth trying this, and maybe looking at the other potions in the "rendering intent" part of the print options.

Already got this ticked

Maybe the customer has a custom profile that was embedded in the original file.

Looks like its profile related. Managed to print same image on my main machine and it was fine. Looks like a profile tweek required!

Sorry to bring up an old topic, but was this a reoccurring problem Justin or was the initial fix a permanent one?

Many thanks

Happening all the while, profile needs re-making for that particular printer.
