EFI RIP and G7 Certification EFI RIP and G7 Certification Hi Levy, Let me try to answer your original question, then move on to this one. First, as Glenn has pointed out, there is currently no specification for individual user proofs in North America as there is in Europe. The default...

Re: HP z3100 as colour proof printer Good question. No, not complete bullshit. The color could be anything from a dark blue to a purplish blue, depending on what you mean by these terms, the car stock, press type, and many other factors, such as wet trapping, etc.. Most people don't realize...

Gray Balance Optimizer Gray Balance Optimizer Mike: I knew I could count on you to charge heedlessly into the Great Debate, but I'm glad it was you and not me. Yes, this is the elephant in the room: custom press characterization and profiling. How many blithely march into this minefield...

Near Neutral and other Products Near Neutral and other Products I was referring to a previous product that measured only primary ramps and thus did nothing to address gray balance. We are both in agreement that this was inadequate and is the reason the Near Neutral product now exists. I do...

G-7 Implementation and DL Conversions G-7 Implementation and DL Conversions Mark: I AM aware, which is why I referred to Prinect's "older press calibration," which is what T-Roy has currently, from his description. T-Roy: You have just heard from H'berg's Rapid Response Team that they are...

Re: Advanced colour management in Prinect Workflow Gads, you've covered a lot of territory in this question and actually raised additional issues. First, Prinect's older press calibration isn't as good as it could be because it measures only C, M, Y, and K ramps, as i recall. This cannot...

CMYK Blacks in EFI ColorProof XF CMYK Blacks in EFI ColorProof XF There should be no great problem in making CMYK blacks neutral in a proof with any good proofing RIP, but certain preliminaries must be attended to. First, the color you're trying to reproduce must itself be truly neutral. Is...

Whoops Whoops Ah--just realized one can edit one's posts later for spelling, etc. Very nice.

EFI Colorproof XF and Profiling EFI Colorproof XF and Profiling All three solutions produce excellent results. The last time I bothered to check such things, the order of accuracy of proof-reference (GRACoL) match on the 1617-patch IT8.7/4 target was 1. Profilemaker 5 2. EFI Color Manager 3...

You mentioned the iSis XL but not the profiling or other program you want to use it with. Colorport targets must be measured with Colorport, though the result may be saved in CGATS or Profilemaker format, or a Monaco Profilemaker session. The ECI reference data is provided in Colorport as a...

I recommend using a specialized proofing paper that has a newsprint substrate but an inkjet receiver coating. I know Mid States and others carry this product. You don't need Color Manager to make this work--Lin Tool and a third-party profiling app will do fine (with a certain workaround). You DO...

Why consider only GMG and ORIS? EFI Colorproof XF v. 4.0 is so much easier to use, has more automation and sophisticated color control--e.g., the "Dynamic Wedge" that verifies proof compliance based on actual image content and generates an L*a*b* correction curve on the fly, scheduled relins...

As someone who has had the opportunity to work with printing, prepress, and design personnel over the years on color management issues I'll offer my own "real-world" perspective. Two common mistakes are frequently made by these businesses. The first is trying to solve complex problems by simply...

Hi Scott, This is a bit like asking, "What is the best car?" It depends on the needs and the budget. After years of testing and using many different proofing papers the issue for me breaks down to a few criteria. 1. Color: must be bright enough and BLUE enough to simulate the brightest and...

I just typed a reply that vanished--thought I was signed in but apparently not--and now read that Glenn has written the same comment almost word for word. Let me add that your plate reader is probably responsible for a lot of the "fluctuation" you see, notwithstanding the mfr's discliamer...

Just to expand a bit on what's been said: So long as the proofing stock isn't dramatically shinier or duller than the target press substrate, abs. colorimetric rendering will allow you to simulate the press paper color. Be sure that the source/reference profile is correct for the press and paper...

HP Z2100 Printers HP Z2100 Printers Hi Todd, These are excellent 8-color printers. Results are extremely similar to an Epson 7800. Reds are a bit on the timid side, but ample for proofing to GRACoL. Built-in spectro and easy recalibration. Never seems to clog, easy on ink consumption. User...

Hi Lee, Colorproof eXpress does not support multiple print queues, for example for simulating different press conditions or for different output media. You must go into the settings and change them each time these parameters change--and remember to change them back. Fiery XF, like Colorproof...

Dot Proofing Solutions Dot Proofing Solutions EFI Colorproof XF has a true dot-for-dot option (called 1-bit TIFF) that uses the actual screened TIFFs that the platesetter uses, so you can use these proofs to check chokes and spreads, and they are color-managed as well. It works extremely well...

Uncoated, TAC, and GCR Uncoated, TAC, and GCR Hi Dwayne, I agree with Mike: stick with a TAC of 260 or below for uncoated. I also endorse the idea of going with a well-tested data set such as Fogra29, if you are making your own profile, which should be done in a bonafide profiling program...
