ICCs were developed for color systems so that they would be more uniform in how they treat color images. For example, they greatly improved the chances that what you'd see on the monitor would match what the printer made. In B&W I'm starting to incorporate ICCs into my workflows. I use Roy Harrington's "Create ICC" program to do this. The ICCs are, I believe, the easiest way to get a good match between the monitor and the print. Because anyone can make these with Roy's program, it allows people to make custom ICCs for their systems. A custom ICC that fine tunes your particular system is generally going to be better than a "canned" one that is made on a different printer. You do need a spectrophotometer or at least a flatbed scanner for this. I'm now using the ColorVision Print Fix Pro (about $500). The version I use outputs a text file that can be used by Roy's program and also can be opened in Excel, which then makes a graph of the output. That graph is a very nice way to see what your system is doing. I'll post a few examples of this shortly. I'm also using the ICCs to control the variable tone inksets. Previously I used Photoshop curves directly for this. Now I make the curves and then embed them into the ICC. This allows printing from a grayscale file with no more need to convert to RGB and then apply a curve. It's an easier workflow. This ICC workflow also allows those with Photoshop Elements to use "profiles" (and the MIS variable tone inksets, for example) even though Elements does not allow the direct use of curves. So, from my perspective, the ICC approach appears to be the easiest way to get top notch control of inksets. On the other hand, I still design the inksets to be useable with no ICCs, additional software, or equipment. The UT-3D inkset I'm working on, for example, allows the highest degree of control of any B&W inkset I've used. However, I expect most with R220 printers should stay with the simple UT-R2 inkset that does rather well right out of the box. There is a lot to be said for simplicity. However, for perfectionists, the additional control is very nice to have. Paul www.PaulRoark.com
