The 3200 in use.
The
3200 scanner first caught my attention through its high resolution film
scanning capability, before I look at that in great detail I put the scanner
through some tests on photographs etc. I have a reference file and carefully
controlled print from the file. The reference file and print are part
of the Colour
Confidence Studio suite.
The maximum document size is 216 x 297mm (8.5 x 11.7 inches) or A4 &
US Letter size. This is standard on most A4 scanners, although I have
know a couple to have a larger area (Microtek). There are ruler markings
on the top and right hand side of the document table, but no figures other
than B5, LTR and A4. Documents have to be aligned with the white arrow
in the top right corner. This is the recommendation in the electronic
manual, but further down the page it states that there is an unreadable
area of 2 and 1.5mm from the edges (see illustration below), for most
practical purposes this should not be a problem. The scanner lid (the
Transparency Unit, TPU) is not sprung, this could mean an expensive slam
down if you let go of it. The TPU can be removed with ease, handy for
scanning thick books or objects.

is even across the whole document table as can be seen in the above scans.
Although I have included a small section of a test target, (this has been
magnified beyond the recomended size). I will not be testing for resolution
numbers in this review, there are plenty of sources for those types of
tests on the net. I will be testing for visual appearance of pictures,
colours and sharpness.
Colour test.
The reference print test below is supplied with the original digital file.
This reference print is produced in small batches which are spectro read
for colour accuracy, in other words the print is about as accurate as
you can get.

3.
Scan with Auto Exposure selected |

4.
Scan using the colour controls in Epson Scan |
The
first picture is the original file, was supplied on CD as a 38mb file,
it has been reduced in size to match the scans. Picture number 2 was made
with No colour correction selected in the Epson Scan Configuration panel.
This mode would be the equivelant of shooting in RAW mode on a digital
camera. Although the scan looks dull and lifeless, it does contain a lot
of untampered with information. You would use this setting if you wanted
to apply a custom profile to the scan. Picture number 3 was made using
the Auto Exposure, this gave a nice looking scan which would be sufficient
for 90% of all scans. The last scan, number 4, has been tweaked using
the controls in Epson Scan software, this could be further improved on
with your imaging application.
Before moving on to the next test, I will clarify using custom profiles
with this scanner. When you use the scanner in its normal mode the scanner
automatically applies a profile to the scan. The profile is based on which
options you have selected, i.e, reflective or transmitted light. Any adjustments
you make are applied on top of the profiled scan, this is a seamless "under
the bonnet" operation which you don't have to think about. When
you select No colour correction, the scan is performed without any profile
being applied. You can't make any colour adjustments to the file at this
stage as the buttons are greyed out. With the scan in Photoshop you have
to Assign a profile, from the menu select Image
> Mode > Assign Profile, select the Profile button and
choose your custom profile from the drop down list. You would of course
need to create a profile using a application such as Monaco
EZ Color 2 or other.
