Help, I want to print a CMYK cross-rendered proof?

[davi russo]

Hello all,

I want to print a CMYK cross-rendered proof, can you please look over this and help?

i am currently using an Epson 3880 and working in CS4.

before posting this, i have been reading all over these boards and also inside the books Real World Color Management and Color Management for Photographers, but i am still unsure of the exact steps i am taking are correct.

here are the steps i am taking.

1. soft-proof and gama warn RGB to CYMK using the desired printer (or generic) swop profile

2. adjust image to desired taste

3. convert from my RGB working space (ProPhoto) to my desired output profile (CMYK U.S. Web Coated SWOP v2) using the rendering intent that gives my image the best results.

4. convert that profile to my Epson (SP3880 2880 Premiun Glossy Photo PK.icc) profile using Absolute Colorimetric rendering

5. in the CS4 Print Dialogue
make a Document profiled print,
PS managed colors,  
Printer Profile is matching the current Document profile, (which in this case is an Epson printer profile?)
Rendering Intent is Relative Col,
with Black Point Comp switched on,
onto paper (Epson Ultra Premium Glossy Photo Paper)

6. trim off unprinted paper, because the difference in white points.

as you might see i am unsure of steps 4 and 5.
can someone please confirm this is a correct way or illustrate a proper way, i know this has been
thank you very much.

That’s where you’re off. You applied all the color management in Photoshop so now you select in Photoshop’s print dialog “no color management”.

Correct.

Hi Andrew,
thank you so much for finding the time to reply on this,
great to know i am good up to step #4

can you please take a look over this
as for step #5 i will attach a screenshot to better explain if my settings are correct to print or not???
for some reason the “no color management” in PS print dialog is not available for me to select, it is grayed out?

Nope. You applied the color management in Photoshop right? So now all you need to do is set the popup to No Color Management and pass the color managed data to the driver.
Now you COULD do this in area if you wanted. You could have converted from RGB to CMYK in Photoshop (Convert to Profile), then set the print dialog as you show, converting from CMYK to Epson RGB (but you’d set Absolute Colorimetric here). In fact you could do the entire three way conversion using the Proof radio button (once you setup a customize proof setup to show up here, something that has always seemed odd to me). Too many possible options.

So for simplicity, stick with what you have (RGB working space to CMYK, CMYK to Epson RGB with Absolute) using two rounds of Convert to Profile. Then set the print area in Photoshop to No CMS and off you go.

thank you again Andrew,
honesty my head was still confused, and i have been going back and firth with this for the past few days, burning throughout many mistakes making tons of 4x6  RGB vs CMYK cross rendered proof prints all over the place..

so, i just now went back into your book and read the tutorial in the back section on cross rending again,
and using the supplied Printer Test File image, and following the three way conversion using the Proof radio button you describe works fine i believe!
i can see this as well, seeing how the Proof print white point is being yellowed by the Absolute Colorimetric at work.
thank you again for finding the time to help!
all my best,
