(Note that a number of the PictureMate printers that were
previously included generated grossly incorrect output. Not
all of the PictureMate printers have been fully tuned at this
point.)
* Canon inkjet printers:
Canon PIXMA MP520 (#1872394)
Canon PIXMA iP6000D
2) Printing for the Canon PIXMA iP4500 has been fixed (#1834153).
3) Printing near the bottom of the page has been improved for many
modern Epson inkjet printers. In addition, we have determined
that most of these printers can print with consistent high
quality at 2880x2880 and 5760x2880 DPI. Therefore, these
resolutions will be used for Ultra Photo and Best qualities
respectively on these printers.
Printers affected include:
* Stylus Photo R800, R1800, PM-G820
* Stylus Photo R2400
* All printers using Claria ink
4) Full bleed printing now works properly on the Epson Stylus Photo
R2400.
5) The Epson Stylus C120 now allows printing at 2880x2880 and
5760x2880. However, print quality near the bottom of the page
may be poor, and these settings are therefore not used for Ultra
Photo and Best quality.
5) The ink drop sizes on the Epson Stylus Photo printers using
Claria ink have been retuned, yielding improved quality at lower
resolutions.
6) A problem with determining the system printer queues in the GIMP
plugin on certain systems using languages other than English has
been fixed.
7) Envelope paper sizes are now offered in both portrait and
landscape form factor, as some printers expect envelopes to be
fed long edge first while some expect them to be fed short edge
first.
PCL laser printers now offer paper trays with adjustable guides.
Many laser printers use adjustable guides for manual feed of
papers narrower than letter size.
9) The GIMP plugin now offers reset buttons for individual
settings, so it is possible to reset a single setting to its
default without resetting all settings.
9) Various new controls and settings have been added to assist in
printer calibration. While the tools for using these controls
are not yet created, these tools will assist in calibrating
printers in the future.
* The Epson driver now offers additional controls for adjusting
the relationship between light and dark ink:
+ The Value parameters (such as Light Cyan Value) specify the
relative darkness of the light vs. dark inks.
+ The Cutoff parameters now specify the point at which the
darker ink is first used, relative to the value of the light
ink.
+ The Scale parameters now specify the amount of light ink
used (essentially the density of the light ink). This is
the same as the parameters previously called Cutoff.
* The Epson driver now exposes as defaults the actual GCR
settings used for the printer, paper, and ink combination in
use.
* The Epson driver now allows passing low level settings such as
printer base resolution, ink drop size selection, and relative
ink drop size as parameters. The ink drop size can be
accessed in the GIMP plugin, while the base resolution and ink
drop size selection can only be used via the test pattern
generator or other application that allows setting integer
parameters.
* Two new dither algorithms, Segmented and Segmented New, have
been added. These are not intended for normal use, and will
normally behave like Ordered and Ordered New. However, if Raw
color correction is selected and a printer with multiple drop
sizes is used, the range of input will be divided up such that
the high order bits will select the drop size to be used and
the lower bits will specify the amount of ink. High order
bits of 0 indicate that all drop sizes should be used.
For example, if a printer offers 3 drop sizes (2 bits), the
range of 0-16383 will print all drop sizes normally (with the
range of 0-16383 being scaled to 0-65535), 16384-32767 will
use the small drop size, and so forth.
This is intended to assist in tuning ink drop sizes.
* A new parameter allowing dumping out of color correction state
(lookup tables, GCR data, curves, etc.) has been added, and is
accessible in the GIMP plugin. At present, this data cannot
be used directly, but it is intended that in the future this
mechanism be used to allow calibration information to be saved
and restored.
