Printing Press Simulation with Acrobat X

Question

I created a CMYK file for press in InDesign CS6 (Mac OSX 10.8.5). I exported from ID to PDF using PDF/X-4. The output intent is Coated_GRACoL 2006 (ISO 12647-2:2004). The file checks out great in ID and Acrobat preflight and all is as it should be.
I wanted to print a hard copy press simulation on my Epson 3880 (custom RGB profiles, no RIP). I set up Acrobat Output Preview with the above profile, Simulate Paper Color and Simulate Overprinting. I left the Output Preview window open. Then I printed it from Acrobat X Pro (v10.1.12). I selected Advanced > Color Management with the following settings:
Acrobat Color Management
Chose my custom RGB Inkjet profile
I checked Apply Output Preview Settings
Then I printed the file. There are pure white elements in this design, and using a loupe, it is clear that no dots were laid down to simulate the paper color. It also appears that the print is darker than it should be, so I don't think it is simulating press blacks, but the deeper blacks I can achieve on my inkjet with a semigloss RC paper. I printed the same file from InDesign and it properly lays down dots in the pure white components and prints a less dense black. BTW, I chose to leave the Output Preview dialog box open in Acrobat, because a previous print from Acrobat also gave me pure whites. I thought perhaps you need to keep that dialog box open to retain the simulation settings, but open or closed, I got the same results.
Maybe I'm doing something wrong, but I can't figure out what it is. Or, is Acrobat not working properly for printing press simulations?
Thanks,
Lou

Answer 1

I'll answer my own question. I think Acrobat is broken and doesn't print accurate press simulations even if you check "Apply output preview settings". At least that is the case with an RGB printer through the driver. I've tried a lot of different options, but none of them worked. I even converted the color to the output intent in Acrobat (as an experiment) and them printed. No dice.
Both InDesign and Photoshop print press simulations properly, but Acrobat X Pro does not.
I just wanted to post this in case somebody else has a similar problem. If somebody finds that I am mistaken, please let me know and post the correct steps or settings to get an accurate Press Simulation on an inkjet from Acrobat.
