I asked our printer for color settings and specifications, and they sent me a .csf file to load for proper color settings. But I noticed that it is almost exactly the same as the U.S. Prepress Defaults settings included with Photoshop—Adobe RGB, US Web Coated (SWOP) v2, 20% dot gain and Black Ink—US Web Coated (SWOP) v2 for grays. I’m most wary of the CMYK setting, which sets black limit at 100 and GCR at medium (just like the default).

I've based my current settings on what Dan's book recommended, and I've gotten good results. Should I conclude that the printer's settings are dubious?

It's a bit of a crap shoot. Is the printer known for high quality printing? If so, there's a good chance they pass the resulting separation through a set of curves to account for their actual press behavior, and if printing on a good quality stock, and printing CTP a 100% black ink limit and medium GCR with good process control in place won't be a problem. But SWOP separations are geared for printing at 133 line screen, conventional platemaking, on a #5 stock. Adapting such separations to different printing conditions is possible but are inferior custom separations for actual printing conditions.

Further questioning of the printer may reveal what happens to your file once they get it. Will it be going through a set of plate curves, or will it be processed using a DeviceLink? Have you communicated to them your level of tolerance for a match between your display and their contract proof? If so, I'd use what they're recommending until proven this is not good advice. If they balk at the display to proof match, and instead bring up the proof to press match, that merely means they are banking on any discrepancy showing up in the proof, and you'll fix the problem at the proofing stage through iterations, and then they will match the proof. A big part of the point of color management is reducing those proof-color correction iterations.

If you get back a proof that is clearly not representative of your file, let them know their suggestion isn't a particularly high quality one. The options, as you see it are: a.) a custom profile for the press or proofing system so you can get closer in one or two iterations; b.) unlimited free proofs and a discount for the time you lose having to guess how their setup behaves.

A printer is obligated to either accept tagged RGB and separate correctly (for a fee, or not as long as this is explained up front), or he is obligated to inform you how his press/proofing system behaves. A 'ballpark' suggestion isn't useful, and it's certainly appropriate to let him know this in the context of 'do we really have a fit here? Should I be looking for a different printer?' But until you've received the first proof, how good their suggested setup is, is an open ended question. But you're suspicion is reasonable.

This is CUSTOM CMYK - not the values of the Adobe v2 profile.

This has been confused many times in the past.

The v2 profile has a 90% K limit and the GCR is not the same as custom CMYK Medium GCR, but it does seem to be a havier or 'medium' GCR more so than light or UCR.

I've based my current settings on what Dan's book recommended, and I've

No, you should conclude that the printers settings are accurate and that they print to TR001 aimpoints.

If you have entered custom CMYK then you have changed their CSF file, the popup menu should now read custom and not have the original CSF name.

Do you mean that the CSF actually has legacy Custom CMYK and not the v2 TR001 profile from Adobe?

Although these two profiles have 'swop' in their name - they do not describe the same thing at all.

As Stephen points out, the black limit and GCR settings are contained in the SWOP v2 setting, which cannot be altered or even examined. When you change to Custom CMYK you get an older default. The 100% ink limit you see is therefore not valid with these settings.

Most printers know almost nothing about Photoshop or how to prepare files for printing. There are some happy exceptions who can make our life much easier. It helps to find out which kind of printer you're dealing with.

Here, the printer has, in response to your inquiry, given you the Photoshop defaults as a file, as opposed to just telling you to use Photoshop defaults. This is not a happy sign. Stephen has indicated that you should assume that the printer prints to those specs. I respectfully disagree. It may be true that they've looked at their output and have made an intelligent decision to use these settings, but I certainly wouldn't assume that.

If you can find out anything more about whether this particular printer has any competence in this area you'll be way ahead. But if all you have to go on is that they've fed you back the Photoshop defaults then the odds are unfor
