Hello ColorSyncers,
I just wanted to add a few perspectives around i1Profiler.
- Smoothness slider. For a well-behaved printer, this slider is not important. The effect is essentially nil.For an ill-behaved printer, the slider is very important. Bad behavior means irregular data. Irregular data is a profiling engine’s worst nightmare. The smoothness slider is there so that - in the event that measured data behaves really badly - you have a remedy. In this case, increasing the value of the slider can have a significant improvement on profile smoothness, although it does slightly reduce the profile’s overall dE accuracy.
- Iteration. It’s an extra step... which means extra pain... but I have seen very good things. The feature itself is not magic. What it does is basically pass a set of lab values through the profile you made (that you are optimizing), creating a new set of device values (for a CMYK printer, a new set of CMYKs). You can then print them, measure them, and add that data to your original data set. In other words, if you start with and IT8.7/4, that’s 1617 patches...and you pass a set of 1617 lab values through the profile...you get another 1617 patches. When you re-build the profile, you are using both sets, or 3234 patches. The fact of the matter is, with enough patience and fortitude, you could have done this same trick with PM5. The difference is that the new i1Profiler engine has the flexibility to accommodate this kind of data and interpolate it into a better profile.
I saw 1 comment on the quality that suggested is was “slightly better than MoncaoPROFILER”. There’s a reason for that: because the i1Profiler software inherited some of the technology that made MonacoPROFILER a great product. What MonacoPROFILER didn’t have is the flexibility to work with custom patch sets. Therefore, MonacoPROFILER could never dream of doing an iteration. On the other side of the coin was PM5. PM5 could take almost any patch set you throw at it but - overall - I don’t think it had the color-modelling chops that MonacoPROFILER did. So what you get now is an extremely powerful set of color modeling algorithms, coupled to a flexible interpreter that can handle any patch set.
This may sound like mumbo-jumbo. In practical terms, for a well behaved device, doing the same exact thing you did with MonacoPROFILER, or even ProfileMaker, i1Profiler outperform the others in a close race. However, i1Profiler has a lot more under the hood. If you want, you can rally push the product to get results from it that were simply impossible using the previous generation of tech.
That’s all for now. Hope this helps. I will be posting more tidbits to www.i1upgrades.com in the coming weeks.
