In the table below PCSTATS has two sets of industry
standard printer test images; the first set are in the original (full size) jpg format, and the second set below are the scanned in copy
of the actual printout from the Samsung SPP-2040 photo printer. Have a look at each
to get a better sense of the image quality capable through dye sublimation
There are some slight colour differences between
the PhotoDisk reference jpegs and the pictures printed by the Samsung
SPP-2040 photo printer. The SPP-2040 firmware also has a mildly annoying habit
of cropping the image to fit into the 4"x6" frame such that a small portion
off every edge is cut off.
We've been able to live with that quirk, but it's the image damage that
happens when a dye sublimation printer encounters dust or lint that is not so
||experts tip: lint and dust control|
Blemishes like this close up section
of photo-print are permanent; the result of lint on the surface
of the photo paper during the printing process. The foreign object
prevented the cyan film from transferring to the paper below.
Here's a suggestion, before printing out your own photos
clean dust and lint from the area around the Samsung
SPP-2040 with a damp cloth so it isn't drawn into the vicinity by static
charges. If lint gets onto the glossy photo paper during the printing
process it will prevent the cyan, magenta or yellow film from transferring
to the paper below. The last pass the paper takes through the machine
applies a clear coating, and by this point lint always seems to
become affixed to the surface of the photo. Keep things clean and dust
free, and the quality of pictures will kept first class.

Dust and Lint - Enemies of Glossy Photo Paper
The PCSTATS labs must be particularly lint filled this time of year, because
no matter how well we cleaned off the special glossy photo paper and the area
behind the SPP-2040, some small particles always managed to get between one
layer of the CMYK film as it was printing. Take a look at the scanned
in photo prints above and see if you can spot the few odd blotches of
colour which don't belong...
While this is
certainly undesirable, in most cases the little blemishes (which are the direct result of dust
or lint on the paper) are very small and go largely unnoticed unless it is over
a solid dark colour.
