PermaJet launched a new range of fine art inkjet media at the
Convention this year. They have taken the opportunity to rationalise the line-up, tweak some products and develop a number of brand new ones.
After 15 years of service the less popular media have been retired and
user feedback has been employed to improve other products.
Changes to the workflow are hardly needed, but we took the new papers
and ran them through our standard audit routines which includes making
bespoke profiles. For completeness we have added back some legacy
data for the unchanged products. The weight reductions should help with
media transport issues that sometimes arise with weightier papers (there
is a limit of 500 microns on an Epson 3880, 270 microns on the auto feed
of the 4900 and 790 microns on the manual rear feed of the 4900. Despite
this we had a train crash using Museum Heritage on the rear slot of the
4900).
The inclusion of alpha cellulose in Museum Heritage is intended to reduce
the occurrence of paper cutting shards contaminating the printed surface
- a small fragment of rag fibre can spoil a print. The stiffness imparted by
the alpha cellulose might have added to the transport problems; it is not
insurmountable, it just needs a bit of care.
Our last full review of the PermaJet range was in 2010 (when we used an
Epson 3800, 3880, 4800 and 4880). When choosing a paper it is essential
to consider the whole range, some favourites have been left unchanged and are as good today as when they were introduced. Generally, the
legacy data are comparable to those measured recently except that
the extended gamut of the 4900 HDR ink set has improved the range
of Pantones that can be reproduced and improved the statistics for
the HiGAM patch set in our audits. Because our testing protocols have
become more stringent, we have only included legacy data which is
relevant or noted the changes with the data.
Choosing a paper for its texture is self-evidently a personal matter. You give up some highlight detail in the undulations but little else. Personally I do not care for the surface of the Artist Watercolour, others may hold
different views!
The choice of base tone and OBA tolerance is more amenable to
measurements. Gallery Etching and Artists Watercolour are OBA free
and slightly creamy - they join Alpha Natural in this regard. Museum
Heritage and Portrait Rag have slightly elevated Fluorescence values and
a moderate loading of OBAs. Photo Art Silk is almost 4 points toward blue
(ie cooler)and has a Fluorescence of 6.8 and joins Portrait White at the
cool end of the range. As the graph shows, the base tones of Portfolio Rag,
Omega Rag, Museum Heritage and Portrait Rag are closer to neutral.

PORTRAIT RAG 285gsm
This classic from the PermaJet range retains its 100% cotton base
and subtle texture while making it marginally lighter at 285gsm.
This product is acid-free and meets the highest digital art standards.
Certified by an independent UKAS laboratory this material, like many
PermaJet products, exceeds the Fine Art Trade Guild's archival standards
and is ideal for Art and Photo reproductions. The original media
has been used for many years as a standard for comparing printer
performance. The surface retains detail superbly. Key statistics from the
audit are the very low values for the Macbeth errors and skin tone errors
of less than 2.0, the error in skin tone lightness values was zero.
PHOTO ART SILK 290gsm
The popular surface and finish of the Smooth Art Silk has been
updated to a 290gsm base offering printer-friendly loading. The
unique ink-receiving layer that exhibits the silk/satin sheen once
printed on has been developed to give greater colour vibrancy and
increased scratch resistance.
Previously we have measured slightly lower gamut volumes for this
media but not this time; this returned the highest values of the range,
30% higher than the last data set with the highest Dmax also at 1.78.

MUSEUM HERITAGE 310gsm
"The new Museum Heritage has been developed in co-operation with
high-quality image reproduction labs to ensure it delivers the maximum
structure where ink can reside and be retained making it the toughest art
surface the world has seen to date."
This is a 310gsm natural white art paper with a pH neutral base that is
delicately textured. Produced from a mix of cotton and alpha cellulose
which gives a soft feel while retaining the rigidity the art printing and
framing makers demand. Museum Heritage 310 delivered a good gamut
volume of 626,217, the highest of the textured media and a colour error
overall of just 3 points.
PermaJet claim that the latest inkjet technology addresses ink transfer
issues in previous versions to provide superior ink retention and full
archival stability. The moderate level of OBAs will give it a bit of a lift to
the tones.
ARTIST WATERCOLOUR 250gsm
The Artist Watercolour 250gsm textured art paper has an off-white base
tone and is made from alpha cellulose. The mould-made base material
has a highly defined rough surface that delivers incredible fine art
prints. The strength of the tooth is more akin to a pastel paper or one that
might be used for charcoal work. It is suited to the reproduction of artists'
watercolour work or the output of photographic images from which you
wish to achieve subtle artistic impressions. It has the second highest
colour gamut volume of its group and a Dmax of 1.65, the highest of the
group. The highlight end of the range is a little compressed as detail is lost
in the structure beyond 246 RGB points. Conversely, the shadow detail is
excellent, differentiating all the way down to 20 RGB points.

GALLERY ETCHING 310gsm
The heavy weight, alpha cellulose 310gsm base is reminiscent of a
modern-day etchings paper exhibiting a consistent and undulating
matt coated surface. Its natural whiteness works in harmony with any
artistic or creative photographic image.
The stand-out statistics of the audit are exceptional skin tone accuracy
and a Macbeth set under 3.0 ?Eoo.
Testing with Canon Pixma Pro 10s
By coincidence we had the opportunity to test some
PermaJet papers on the Canon Pixma Pro 10s. This is a
10-ink machine using Lucia inks including three blacks/
greys for improved monochrome renderings. It also sports
a Chroma Optimizer to enhance glossiness and expand the
gamut. A noteworthy feature of the testing was the disastrous
installation onto the Mac operating system (it wasn't us guvnor
the client did it!). It is vital with some consumer printers to install
the driver software first and THEN plug the printer USB in. Not
doing so causes the Mac to install the Gutenprint driver which is
an open-source driver which disables the colour management.
This is evident by the greyed out dialogue radio boxes in the
driver that you ordinarily expect to see. It's a long story but we
were unable to resolve the issue on our first visit but we did
audit the results we had obtained using the Gutenprint driver
and at least left the client with the ability to run work out.
Interestingly, the output was quite good once a suitable media
setting had been matched to the PermaJet Art Silk (we settled
on Canon1/2 Pro paper Glossy Gold). The result was an average
error of just 3.3?Eoo which is good for this class of material
without bespoke profiling. We were unable to bespoke profile
because we could not disable the printer colour management
in the interfaces we were being offered. For anybody who is
suffering from this issue, the solution is to delete the printer in
the Mac system, unplug the USB, install the latest drivers and
then plug the printer back in.
We are minded to come back to this issue and get the new
Prograf Pro 1000 printer in for a review and really get to grips
with things - watch this space!

Overall
Overall then the rationalisations and refinements of
the Permajet Fine Art range are a useful addition to the
media landscape. They perform every bit as well as their
predecessors and in some cases better. PermaJet have a
test pack available at £9.96 ex VAT, one for Smooth Fine
Art, one for Textured Fine Art. The pack also includes
a swatch set. Go try it for yourselves, you won't be
disappointed!
