- Thread-topic: Do I need to upgrade to i1Profiler?
My reasons for Oupgrading¹ to I1Profiler were quite straightforward I need
to produce CMYK+R profiles for the new range of HP DesignJet Z6200 printers
and my ProfileMaker license doesn¹t support CMYK+N. I say Oupgrade¹
because it proved cheaper to buy a new copy of i1Profiler rather than
upgrade my existing ProfileMaker v5 for some reason.
I create profiles for large format and proofing printers using a variety of
RIP software. Some of this software already has CMYK+N capability of its own
(Onyx), some have licensed it from X-Rite (Caldera), but some, such as
Wasatch has no profiling capability at all. For this I use the calibration
tools within the RIP or printer (channel ink limit, linearisation, total ink
limit) and then create the profile externally.
This is where some of the limitations of i1Profiler vs ProfileMaker have
become apparent, after having excitedly ripped open the packaging the end of
last week.
Measure Tool allows me to measure the chroma of CMY and the density of black
to test where I should apply the individual channel ink limit for
linearisation of the device/RIP. There seems to be no equivalent in
i1ProfileMaker. Similarly, after deciding the ink limit for the R channel
(on the Z6200), I would like to measure the Lab value of it in order to use
it to generate the CMYK+R profiling test chart. Again, I have to either
revert back to Measure Tool to do this in Lab or use i1Profiler Pantone
Color Manager to choose the nearest Pantone colour to it.
The chart generated for CMYK+N is a DCS EPS file. This means that I have to
open it in Photoshop and resave it as a PSD file in order to add it to most
RIP software. Why doesn¹t it allow me to create it as (for example) a PDF?
Having said that I have created CMYK+N profiles (linearised, limited and
profiled) with Wasatch/i1Profiler and straightforward RGB profiles with
Wasatch/i1Profiler and the two are pretty much the same despite the
different workflows.
I like to prove that my profiles are working to a customer with my own test
files (nothing spectacular, just a technical file, a greyscale file a
vibrant RGB file and a vibrant CMYK file all judged visually and in the case
of the technical file judged visually against a reference). One of the
things that attracted me to i1Profiler is the Printer QA feature I was
hoping to use this to implement a more technical proof of the quality of my
profiles on RIPs that don¹t have certification but it only seems to support
CMYK and not CMYK+N or RGB printers.
Other gripes: it doesn¹t seem to be particularly fast. At first glance it
appears to be menu-driven but isn¹t. Also, it doesn¹t put files
automatically in the right place moving from creating a CMYK+N profile to
an RGB profile, it wanted to put the test files in the CMYK+N slot. It¹s
only when I went looking for the files that I discovered this.
Nothing wrong with trying to make profiling into more of a mass-market
activity, but my first impressions are that a few too many higher-end things
have been dropped in order to achieve this.
