Printer
Description: Available in a number of configurations
in 42-inch and 60-inch printing widths, the HP5000 and the
Adobe PostScript
enabled HP5000PS are
6-ink (CcMmYK) roll-fed
printers capable of printing up to 1200 x 600 dpi resolution.
Shipped with a choice of either dye-based or pigmented inks,
Hewlett-Packard
supplies ink change-over kits that make it possible for the
user to switch the printer’s type of ink. Prices for
the HP5000 series printers range from $8,995 for the 42-inch
non-PostScript model to $18,995 for the 60-inch PostScript
enabled unit. The Hewlett-Packard
DesignJet 5500-series printers introduced in mid-2002 are faster-printing
versions of the 5000-series printers;
both employ the same HP pigmented and dye-based ink sets and
both provide the same print permanence ratings for the various
types
of media. |

Notes
on These Tests: 2) In
typical indoor situations, the “Displayed Prints Framed
Under Glass” test condition
is considered the single most important of the three display conditions
listed. All prints intended for long-term display should be framed
under glass or
plastic to protect them from staining, image discoloration, and
other deterioration
caused by prolonged exposure to cigarette smoke, cooking fumes,
insect
residues, and other airborne contaminants; this precaution applies
to traditional
black-and-white and color photographs as well as inkjet and other
types of digital
prints. 3) Displayed
prints framed with ultraviolet filtering glass or ultraviolet
filtering plastic
sheet generally last longer than those framed under ordinary glass.
How much
longer depends upon the specific print material and the spectral
composition of
the illuminate, with some ink/paper combinations benefitting a
great deal more
than others. A few products even show reduced life when framed
under a UV
filter because one or more of the image dyes or pigments is disproportionately
vulnerable to fading caused by UV radiation, resulting in more
rapid changes in
color balance than occur with the glass-filtered and/or the bare-bulb
illumination
conditions. For these tests, Acrylite OP-3 acrylic sheet, a “museum
quality” UV
filter supplied by Cyro Industries, is used. Keep in mind that
the major cause of
fading with most digital and traditional color prints in indoor
display conditions is
visible light and although a UV filter may slow fading, it will
not stop it. 4) Illumination
from bare-bulb fluorescent lamps (with no glass or plastic sheet
between
the lamps and prints) contains significant UV emissions at 313nm
and
365nm which, with most print materials, increases the rate of fading
compared
with fluorescent illumination filtered by ordinary glass (which
absorbs UV radiation
with wavelengths below about 330nm). Some print materials are affected
greatly by UV radiation in the 313–365nm region, and others
very little. “Gas
fading” is another potential problem when prints are displayed
unframed, such
as when they are attached to kitchen refrigerator doors with magnets,
pinned to
office walls, or displayed inside of fluorescent illuminated glass
display cases in
schools, stores, and offices. Field experience has shown that,
as a class of media,
microporous “instant dry” papers used with dye-based
inkjet inks can be
very vulnerable to gas fading when displayed unframed and/or stored
exposed
to the open atmosphere where even very low levels of ozone and
certain other air
pollutants are present. In some locations, displayed unframed prints
made with
microporous papers and dye-based inks have suffered from extremely
rapid image
deterioration. This type of premature ink fading is not caused
by exposure to
light. Polluted outdoor air is the source of most ozone found indoors
in homes,
offices and public buildings. Ozone can also be generated indoors
by electrical
equipment such as electrostatic air filters (“electronic
dust precipitators”) that
may be part of heating and air conditioning systems in homes, office
buildings,
restaurants, and other public buildings to remove dust, tobacco
smoke, etc. Electrostatic
air filtration units are also supplied as small “tabletop” devices.
Potentially
harmful pollutants may be found in combustion products from gas
stoves;
in addition, microscopic droplets of cooking oil and grease in
cooking fumes can
damage unframed prints. Because of the wide range of environmental
conditions
in which prints may be displayed or stored, Display Permanence
Ratings for
the bare-bulb illumination condition will not be listed for paper/ink
combinations
of known susceptibility to gas fading. Therefore, prints made with
microporous
papers and dye-based inks should always be displayed framed under
glass or
plastic. 5) Prints
stored in the dark may suffer slow deterioration that is manifested
in yellowing
of the print paper, image fading, changes in color balance, and
physical
embrittlement, cracking, and/or delamination of the image layer.
These types of
deterioration may affect the paper support, the image layer, or
both. Each type of
print material (ink/paper combination) has its own intrinsic dark
storage stability
characteristics; some are far more stable than others. Rates of
deterioration are
influenced by temperature and relative humidity; high temperatures
and/or high
relative humidity exacerbate the problems. Long-term dark storage
stability is
determined using Arrhenius accelerated dark storage stability tests
that employ a
series of elevated temperatures (e.g., 57°C, 64°C, 71°C,
78°C, and 85°C) at a constant relative humidity of 50%
RH to permit extrapolation to ambient room
temperatures (or other conditions such those found in sub-zero,
humidity-controlled
cold storage preservation facilities). Because many types of inkjet
inks,
especially those employing pigments instead of dyes, are exceedingly
stable when
stored in the dark, the eventual life of prints made with these
inks may be limited
by the instability of the paper support, and not by the inks themselves.
Due to
this concern, as a matter of policy, Wilhelm Imaging Research does
not provide a
Display Permanence Rating of greater than 100 years for any inkjet
or other photographic
print material unless it has also been evaluated with Arrhenius
dark
storage tests and the data indicate that the print can indeed last
longer than 100
years without noticeable deterioration when stored at 73°F
(23°C) and 50% RH.
Arrhenius dark storage data are also necessary to assess the physical
and image
stability of a print material when it is stored in an album, portfolio
box, or other
dark place. The Arrhenius data given here are only applicable when
prints are
protected from the open atmosphere; that is, they are stored in
closed boxes,
placed in albums within protective plastic sleeves, or framed under
glass or highquality
acrylic sheet. If prints are stored, displayed without glass or
plastic, or
otherwise exposed to the open atmosphere, low-level air pollutants
may cause
significant paper yellowing within a relatively short period of
time. Note that these
Arrhenius dark storage data are for storage at 50% RH; depending
on the specific
type of paper and ink, storage at higher relative humidities (e.g.,
70% RH)
could produce significantly higher rates of paper yellowing and/or
other types of
physical deterioration. 6) Glass-covered
light stability tests with HP Durable Image Gloss UV had reached “>
400 years” at the time of this publication and tests are
continuing. However,
until long-term Arrhenius dark storage data are available for this
paper, the prints
will be rated as “>200 years.” 7) Glass-covered light stability tests with HP Studio Canvas had
reached “>380
years” at the time of this publication and tests are continuing.
However, until
long-term Arrhenius dark storage data are available for this paper,
the prints will
be rated as “>200 years.” 8) Glass-covered
light stability tests with HP Heavyweight Coated Paper had reached “>
300 years” at the time of this publication and tests are
continuing. However,
Arrhenius dark storage data indicate that this paper is more prone
to yellowing in
the dark than the other HP media listed and, until additional Arrhenius
data are
available, the prints will be rated as “>100 years.” 9) Glass-covered
light stability tests with 3M® Changeable Opaque Imaging
Media
had reached “>380 years” at the time of this publication
and tests are continuing.
However, until long-term Arrhenius dark storage data are available
for this
paper, the prints will be rated as “>200 years.” 10) Some
inkjet prints made with dye-based inks have poor humidity-fastness
when
stored or displayed in commonly encountered conditions of high
relative humidity
(e.g., 70% RH and higher). With some materials, humidity-induced
deterioration
can occur very quickly when the prints are in a warm and humid
environment –
sometimes within only a few days after printing. These problems
may include one or more of the following: |
