Object printing dark grey in photoshop..not deep black

I have a vector smart object that I'm trying to print in Photoshop. It's C-75 M-68 Y-67 K-90, which I was under the impression is "True Black." However, when I print it it still comes out dark grey not black. When I print the same thing in Illustrator it comes out as true black.

What am I missing? Any help would be much appreciated.

Re: Object printing dark grey in photoshop..not deep black

What are the settings you use to print, in particular as they pertain to Color Management?

What is the image’s Color Space?

It's C-75 M-68 Y-67 K-90, which I was under the impression is "True Black."

CMYK per se has no real »true black« (and 100/100/100/100 is generally not permissible in real-life printing), it depends on the individual CMYK Color Space’s GCR/UCR and TAC.

Re: Object printing dark grey in photoshop..not deep black

Hi Karl,

That should not be happening, as it's not a typical experience with Photoshop. Let's make it right.

As blacks are printing as dark grey, could you please let us know the version of Photoshop and operating system you're working on?


Could you please make sure of the following things:

  • Image > Mode > CMYK Color is checked.
  • View > Proof Setup > Working CMYK is checked.
  • View > Proof Colors is checked.

Let us know if it helps.
Regards,
Sahil

Sahil,

All of the settings you mentioned match mine. Still printing dark grey. I'm using Photoshop 2015 on a new iMac.

You're probably seeing the normal default behavior in the two apps.

Illustrator by default remaps CMYK rich black to RGB 0-0-0, when it outputs to RGB devices like an inkjet printer. You set this in Ai preferences > Appearance of black:

Ai_black.png

Rich black is inherently a little lighter than RGB black, since you can't have 100-100-100-100. That doesn't necessarily reproduce the actual reflectance of ink on paper, just this reduction from 400% ink to actual ink limit.

Anyway, Photoshop doesn't have this option. It's permanently set to "output all blacks accurately".

Is the image in CMYK colorspace if so which one? Or is it still in RGB colorspace...if so Which one?

Actually what I wrote isn't correct and I have no idea where my head was there...it was late. Sorry.

This Illustrator preference is an option to display 100K black in the same way as rich/4-color black. Printing on the black plate only produces a charcoal gray, compared to the deeper black you get when printing all four inks.

There is still a small lightening of blacks when you convert from RGB 0-0-0 and into a CMYK profile with a total ink limit less than 100% on all plates.

So what CMYK profile are you using, and is this consistent in the master file <> smart object?
