OK, I spent all day yesterday making new scans, new targets, and new profiles using 8.4.
I use basically, 4 papers.  Epson Ultra Premium Glossy Epson's standard for glossy paper, Ultra Premium Luster, my favorite, Ultra Presentation Matte, (if you need to use a matte, it's pretty good and not expensive), and my give away paper, HP Advanced Glossy.
I still have Ilford Pearl in the closet, but I don't intend to buy any more.  Epson's Luster is just too good.

OK Profiling:
All the chatter that prevailed over 8.1, 8.3 was well deserved because it created the fine tuned 8.4
The intent setting when using your profile is up to what paper you are profiling and the ink, and even what printer driver.
The intent setting choices are P or RC.
To boil it down, you are going to make one profile per paper type anyway,. You don't have to make two to see which way you like it.
Make a test print with P Perceptual setting, and one with RC, Relative Colorimetric.
The RC setting might give you 2 skinches more saturation.
For you Metric people, 1 Skinch = .001 millicolours

Select the one that is most natural and accurate. Put the dot in the P or RC in the profile setup box, and then SAVE P Printer setup with a good name.

Screen snap below to help.

Now let's try that Epson profile for the Ultra Premium Glossy again.
I wanted to show how much better the Profile Prism came out, and I scanned my print to show here.
It was too many operations. Scans and resize and screen snap.... save at a lower Quality....
So I found a better way.
This is REAL!

Now if I can beat the Epson Premium Glossy profile, you can too.  
Imagine that you will improve all your papers if you can improve on the PGPP paper.

151 shows where to find the Profile setup screen
152 shows the setup screen and where to change  the INTENT P or RC
149 and 150 show the Epson vs. Profile Prism   (Both profiles using P)

I am having a ball.
Hope you are too.

Peter,

Whatever happened with your impressions on 8.4?  You said you were going to try it but then never reported back.

Regards,
Mike

The gamut hull won't change much because the profile is mostly just associating different RGB values with the same gamut.  The profile knows the real gamut of the printer/paper/ink and we are really only changing the RGB values that are mapped both inside and out of that gamut.  Still, the gamut won't really change so what you see in a gamut representation (3D map) won't change much if at all.

I use a LiDE 200 but any scanner with an LED light source is best.  I believe that leaves the Canon LiDE scanners and the Epson V500, V600 series.  Those are just the ones I am aware of so if you find others (maybe HP has some), just post here.

Hello Mike.

Following your recommendation I reprinted and rescaned all five Ilford papers I use, using an "LED" scanner, the Epson v500.

There are subtle differences in the 3D display of the colour profiles cf the older scans using the Epson 4990. Whether the differences are due to using the LED scanner and/or the more recent printing is not clear. Nevertheless I was happy with the "LED" generated output.

Since then I have regenerated all profiles using PP 8.41 and printed the same test image used in all the recent PP deliberations. I printed other images as well.

For my purposes, the PP 8.41 generated profiles are my choice over PP 8.0.   

I appreciate this further development of Profile Prism.

Regards

Peter
 

Yes!~  Yes Yes!
Oh Peter, I do this over and over, and could kick myself.

Fred

I will try, but I know it will involve buying him lunch.
Can you cover the tip?

Fred
