Overall very good.

I purchased PP because I lost all my profiles for my Epson R320 when I switched to a new computer.  PP ultimately worked well however, it took a bit of work to get there.  My HP scanner only had brightness and contrast adjustments and I was getting far too many XXs on both the target and printer profile.  I ended up purchasing Vuescan for my scanner software.  The secret to getting this to work well was to use RAW files to feed profile prism.  With that said, the profiles for the Epson R320 (dye ink) were very good.  I then decided to do a profile for my Epson Stylus Photo R1800 (pigment) even though I already had Epson supplied profiles for my papers.  The profile I created using PP for the Epson Premium Glossy was better than what Epson supplied.  Surprisingly, the test prints from the R320 and R1800 matched up almost perfectly.

Overall it works well for printer profiling but there is a learning curve.

I also profiled my scanner with PP.  Using a RAW file, the messages back from PP were not encouraging.  Mike responded to my posts concerning this and implied that these messages were not surprising and that I should just use the data and the results shuld be good.  He was correct and the scanner profile seems to work fine.

I'm using Vuescan to do the scanning and am creating RAW files for the scan of the target hence the settings in the COLOR tab of vuescan shouldn't matter.  I have created printer profiles but am now trying to create a profile for my HP 4850 scanner and am having an issue in Prism.

When you bring the RAW file for the target into Prism, it asks a YES/NO question as to whether you are creating a printer profile.  It instructs you to answer NO, if you are creating a camera or scanner profile.  So, I answer NO.  The RAW file/image of the target is very dark in the viewer and gives poor results.  If I answer YES (for printer profile) the same file comes into the viewer with a much brighter and easier to work with image and also give excellent results as far as X outs, illumination, etc.  What's happening and how should questions be answered to produce a scanner profile?

Screen shot of the bad results attached.

In trying to use RAW images I started out with .dng but when move into the PP folder they seemed to disappear although if you try to move another .dng scan with the identical name you do get a message.  Does this mean you need to use RAW files that are TIFF?

Thanks,

I'm a new user to PP and just started using VueScan in order to get better profiling scans.  I've been spending too much time making adjustments in the color panel of vuescan.  While reading older posts, it is suggest to use RAW and dispense with the adjustments.  Does this mean that I'm sending the RAW file directly to PP?

Thanks,
