Bill Atkinson 1728 target for i1

[ericstaud]

Hello,

So I've read that I can replace one of the Eye-One reference files with Bill's 1728 patch reference file.  I am having trouble making it work though.

I took the file named "RGB 1728 Eye-One.txt" renamed it to "i1 Easy RGB 1.2.txt" a swapped it with the real "i1 Easy RGB 1.2.txt" in the i1 folder.  It shows up in the pull down menu, but..

When seleted, the image that shows up in Eye One Match looks a little off....

This is what the measurement window looks like:

It should just look like a turned version of this, right?

Also, The real printed chart has 48 Rows to measure, the version in i1 has only 34 Rows.
When I try to measure the first row it only gives me an error.


To Print the test chart I used photoshop...
Leave image as is (no color management)
Color Management: Document Profile:  Untagged RGB
Options:  No Color Management
Epson Driver:  Premium Luster Paper, No Color Management.

The Printed chart looks like image of the chart on the computer screen.

I did a search here and on google, but could not find a more thorough description of the process and what I may be doing wrong.

From memory, Bill's targets all use gaps to differentiate one patch from another. Instead of using Match to read the target, use the PM5 MeasureTool in Spectral mode and specify "Strip with gaps".    Read from left to right only. When all the patches look good, save the measurement file and load it into Match to generate the profile. You can also use MeasureTool to compare multiple readings of a single target.

Thank you Stephen,

The test chart does have gaps in it.

I have just installed PM5 Photostudio and the MeasureTool is in that folder.  It needs the dongle to run though.  I made the 50% off Photostudio purchase last week, so the dongle is in the mail to me.

Because I will have PM5, I would just use PM5 to build the profile once the measurement is done, correct?  PM5 should provide me with all sorts of confusing options to mess up the resulting profile

On my 3800, with the canned profiles, there is banding in the shadows and the stepped grayscales have colorshifts.  Based on other user's forum posts, I have decided to just go straight to the larger 1728 chart and not spend time with the i1 918 patch chart.

An appropriate dongle is required for averaging etc. but you can still use it now for measurement and comparisons. PhotoStudio doesn't give you any more MeasureTool functionality than what you've already got (or so I believe). You need to license the Publish Plus package or pay additional fees to get full MeasureTool functionality. Bummer eh?

I don't have a PM5 license but my understanding is that it will do everything Match does so you won't need it anymore. Match is hardwired for LOGO Colorful gamut mapping and auto OBA detection.

The MeasureTool doesn't work at all for me right now.  So the dongle will add at least that.  I have found one reference on the web that states the MeasureTool will not average in PhotoStudio.  I have found other product descriptions that just list averaging as a standard feature of PM5 with no mention of different versions of the MeasureTool.

When I bought the PhotoStudio version the sales person had been told by Gretag there was no SG color checker included in the sale version.  Of course, every web site listing the PhotoStudio version listed the SG checker as included.  He had to call the director of sales for the U.S. to find out the real answer (that it is included).  This is a Sales Person who is the specialist in profiling software, working at a web store that specializes in profiling software.  If he did not know, how should we be able to decipher the marketing materials?

Anyway, when the dongle shows up, I will back here posting more question (and possibly more rants).

Thanks again.

It won't see the spectro until you quit Match.

[madmanchan]

First, quit Match. Then plug in your Eye One (the device), launch MeasureTool, go to Configuration mode. Make sure it locates your device. (Should say OK in the box.) If not, then you might try toggling from Reflective to Emissive and back to Reflective, just to get MeasureTool to find your device. Ultimately you have to make sure you choose Reflective though and make sure that Spectral is checked in the configuration box.

Once MeasureTool has found your device, you will be able to access the other features of MeasureTool, including the button for Measuring charts. You will then need to load the reference text file (.txt) and choose "Strips with gaps" for the measurement mode. The order of scanning matters. Make sure to start with row 1 and to scan from left to right (i.e., starting with the white patch).

Once you are done scanning, if you will be building profiles with Match (or ProfileMaker one day), then go to File menu, Save As, and save the measurement data as text. If you think you might one day build profiles with a separate tool such as MonacoPROFILER, also click the Export LAB button and save a separate measurement file.

Hi,

i1match relies on adjacent patches varying significantly in contrast in order to differentiate one from the other.

You would need to jumble them up in order to use i1match. It is however possible as i1match supports upto 4 pages of chart squares at 34 rows.

If you want to duplicate Bills profiles then you need to use PMP measure.

A clarification to my post above: for Bill Atkinson's Eye One targets, use MeasureTool to measure the targets and save the data, then use Match to build the profile from the saved data. Don't use Match to read/measure Bill's targets.

Thanks everyone,

I guess I had wrongly assumed that, because Bill's profiles where called "Eye-One Profiles", that I would use i1 to measure them.  

I have not been running i1 Match while trying to use PM5.  I am out of town for the day, but I will try to get the MeasureTool to work on Tuesday.  It is currently telling me that it is working in Demo Mode.  MeasureTool DOES see the Eye-One Spectrophotometer.  I have tried re-plugging in the spectro so that it hasn't been talking to i1 Match behind my back.  In MeasureTool it only shows an option to create a target (but does not give me an option to save the target).  The other tool buttons are grayed out.  All of this will become a mute point when the dongle shows.

Stephen, which PM5 did you install?  Maybe the PhotoStudio version is a little different in the funtionality of MeasureTool sans dongle.  You did not find a standalone MeasureTool, correct?

Once I get it up and running, will there be any qualitative difference to profiles generated in i1 versus PM5 using the same settings?  Does anyone here prefer different settings in PM5 rather than using the default i1 settings?  I am making pretty straight forward prints on Premium Luster, Premium Glossy and a few matte papers.  Some go in a portfolio, some will be framed and hung on a wall.

I'm using the MeasureTool from the PM 5.07 download. Prior to that, I used PM 5.05 without problems. I'm not sure what's happening your end ... but it should work as outlined above.

[madmanchan]

As I noted above, if the "Measuring Chart" button in MeasureTool is grayed out, then you need to make sure that MeasureTool has found your device properly. When I first loaded up MeasureTool myself, that button was grayed out. I needed to first click on the "Configuring Device/Port" button, then click on the Emission button, then click on the Reflection button. Somehow, this sequence of steps triggered MeasureTool into finding the device properly. After that, the "Chart" and "Spot" buttons under the Measuring section of the toolbar became available.

You do not need a dongle or a software license to measure charts or perform spot measurements using MeasureTool.

Charts that you can use directly with i1Match have two critical requirements:

1. Jumbled patches
2. Pages have exactly 17 rows of patches each.

You can have more than 4 pages of patches - the GUI misbehaves a bit, but it still works.

If you don't have a total number of rows being a multiple of 17, you cannot complete the chart reading phase.

SUCCESS!!!

I got home tonight and went straight to it.  The Measure button on the toolbar was still grayed out, and would not respond.  I went to the "Tools" pulldown menu and "Test Chart Measurement was not grayed out, and would respond.  

I measured the Atkinson 1728 chart and then made a profile in i1 Match.  By the way, later I went back to the MeasureTool and the tool strip was no longer grayed out.  Go figure.

Compared to the canned profiles the custom profile has smoother gradations (not perfect),  more gray uniformity in the stepped grayscale, and less yellow cast overall in the grays.  The colors also reach much deeper saturation across the board.

Thanks for all your help.  When the Dongle shows up I will let you know which other MeasureTool features are activated.  Here is the current setup, sans dongle:

[attachment=1408:attachment]

I am going to print another chart with Hi Speed turned off this time.  I think I also need to run the alignment on the printer as well.  This may help improve the profile, as I think I'm seeing some vertical lines.

Does anyone have an opinion about the point of diminishing returns in printing the larger 3600, 4096, or 5202 patch profiles created by Bill Atkinson?
