Hi Guys,

I just got a box of Inkjet Art Micro Ceramic Luster and tried to
profile it tonight. Its been nothin' but trouble from the start.

I printed the 225 patch target along with the grays last night and let
the dry 24hours. When I read the color target I placed it over two
unprinted sheets of micro ceramic luster, and after doing the reading
it showed a b value of something like -91 in the Ref White dialog box!
I new something was wrong from the start. I remembered that as I was
reading the patches there seemed to be a lot more light being
reflected up from the paper as the spectro read each patch.

So I assumed the paper has something weird with the OBAs. I removed
the two backing sheets, and re-read the color target while it was
placed over a black piece of cardboard. This brought the b value down
to about -8 in the Ref White dialog. So I next scanned the gray target
over the black backing and built the profile with all defaults in
Spyder Print 3. While looking at the soft proof page I could also
readily see that something is still wrong with the profile. The photo
with the blond woman in the dark coat had an ugly hard dividing line
between the sky and the trees behind her.

I re-examined all of my patch readings, and everything looks normal. I
then tried regenerating the profile without checking the ref white
box, but this made no difference. I then regenerated the profile with
only the color target. At this point the color only profile looks
normal. The soft-proof looks better than the one generated by the
canned profile supplied by IJA (which is way too blue-another hint
that the OBAs are weird in this paper). I haven't printed with the
color only profile yet (I only have 2 extra sheets available for the
project I bought this big box of paper for). 

What could be wrong here? Why is the black target breaking the profile?

Here are the two data files generated by PFP:

Thanks David,

I'll clean the tile and re-measure. Have you heard of this type of
problem with the IJA Micro Ceramic luster before? I've measured many
other RC papers like this and not seen the spectro freak out in such a
disastrous way.

Also why does the weirdness really only seem to come out when I add
the gray measurements?

Derek

Actually your response leaves me even more confused.

I printed the color and gray targets on the same sheet of 11x17 paper
that was cut in half to 8.5x11. Printed within 5 min of each other and
left to dry down for 24 hours before measuring. The high negative b
values only occurred when measuring over multiple sheets of paper, it
was something like -9 over the black backing sheet. For the final
profile I measured both the color and gray targets over the black
backing sheet. So there should be no difference at all between the
color and gray targets.

As far as the spectros go, do you have different classes of spectros
designed to accommodate extreme levels of OBAs? If so does this limit
the spectro's accuracy when measuring papers with lower levels of OBAs?

Gack! Oh the complexity! This box of paper was $25 less than a box of
Epson Premium Luster, maybe this wasn't a good trade off :-(

Cleaning the tile did make a difference in the negative b values,
which went from -91 to -7.x on paper white.

However the profile is still wack. The same problem exists where the
transition between the sky and the trees has a harsh ugly dark line.
After cleaning the tile I remeasured both the gray and color targets
and regenerated the profile.

I tried opening a ticket at Colorvision tech support, but they closed
it immediately 'because I had corresponded with you here on this
forum. No one has replied to my further comments after they closed the
ticket.

I responded to the reopened ticket in our support area a couple of hours ago;
if you could go back in and attach your latest measurement files, I'd be
glad to have a look at them.

I have profiled the Inkjet art luster and it came out very nice using
the Printfix Pro, if that helps at all.

I have been running an olde (AMD 3200!) pc with dual LCD monitors and 
happily printing with profiles & calibration a la Printfix Pro and spyder.

Having just acquired an HP Pavilion dv6500 special edition laptop, I was 
contemplating connecting my main LCD screen to the laptop while using 
the laptop's screen as the secondary monitor.  The laptop has analog and 
HDMI outputs - I was told I could get and HDMI-DVI adaptor to run the 
outboard screen.  Then I can retire the olde beast and run a quicker and 
quieter machine.

While I think it's feasible to do this, and I'm going to give it a try 
in a day or so when the latest project delivers, are there any landmines 
to watch for?  The laptop has an NVIDIA GeForce 8400M GS video card with 
128 meg of RAM, the computer's RAM is 2 gig.  Of course the laptop is 
running Vista, and I'm also concerned about printer drivers - have not 
looked into updates and will do so - I run Epson 2200 and 9800.  My main 
screen is a Viewsonic 21" which is ok for now, some day I'll upgrade that.

Thanks for any hints or help on the subject!

Thanks CD, I can live with not having my toolbar monitor calibrated.

Setup

Windows Vista, spyder3print 3.0

Ilford Classic Pearl.

3 page color target plus black and white target.

 

Problem

On "print proofing" the profile in "spyder3 print" the  black and white
images have a color cast with obvious yellow areas in the 4th target.

Prints from printer are OK.

Spyder2pro 2.3.5 used to calibrate screen 

 

Any advice?
