      Canon PIXMA iP1900 (EXPERIMENTAL)

1)
I want to get old 1000 and 2000 series in as well (various up to about iP2500). I have to printjobs, and need to get the code updated this weekend.

2) I hope to get confirmation on MX870, and if so I will fix the other devices' command sets to the same.

      Canon PIXMA MX300 (EXPERIMENTAL)
      Canon PIXMA MX310 (EXPERIMENTAL)
      Canon PIXMA MX330 (EXPERIMENTAL)
      Canon PIXMA MX340 (EXPERIMENTAL)
      Canon PIXMA MX350 (EXPERIMENTAL)
      Canon PIXMA MX700 (EXPERIMENTAL)
      Canon PIXMA MX850 (EXPERIMENTAL)
      Canon PIXMA MX860 (EXPERIMENTAL)
      Canon PIXMA MX870 (EXPERIMENTAL)
      Canon PIXMA MX7600 (EXPERIMENTAL)   
 
2) Add additional photo modes to Canon inkjet printers. 

I plan to add the 300dpi draft modes to all Canon printers that I have not customized yet: these modes exist for all so it is safe to add the 300dpi modes to existing printer models that currently have only a single 600dpi mode.

It will be a long weekend, but I think I can get it done.

Gernot

Hi :)

Did you want to include the PostScript speedup patch I submitted a while
back (at the same time as the postscript options patch)?  I'd more or
less forgotten about it, actually, until a PhotoPrint user asked the
other day if there was any way to speed up printing to an HPIJS-driven
printer (via the ps2 Gutenprint driver), so I directed him to the patch.
  His response was:

"Your patch ROCKS!  The diference is impressive.
Are you send it to the Gutenprint team in order to be included?"

It can be found here:
http://www.blackfiveimaging.co.uk/gplcompliance/GP524_PSSpeedup.patch
and works by batching writes into blocks, rather than writing the data
byte by byte.  It seems to make very litle difference on Windows, but a
*huge* difference on Linux.

All the best

Feature || Bug ?

I know I promised to shut up for a while, but I see you really want to 
release 5.2.7, so here is another serious question/observation.

Setup: The same (Amd64, Linux 2.6.37, Gimp 2.6.11, Gutenprint 5.2.6,
        ESP R1900

Print: iT8.7 Reference Target

Observed:  In the Adjust Output window, the Brightness field.
            If one reduces Brightness below 1.0, rather than darken the
            colors, it appears that K ink is added to the mix.

Verified:  Observable on the 'preview' image at the top of the form,
            as well as  the preview/place image in the main form.

Confirmed: Inspecting printed image under magnification clearly shows
            increasing density of black dots over the CMYOR dots.

Problem:   Adding K to the print causes colors to be increasingly
            muddy/gray.

Correct:   Perhaps lowering the gamma should be considered.  This will
            cause colors to deepen, and image perceived 'darkness'
            increased. This will, of course darken highlights, but will
            track what many observers will find more customary.
            If highlight loss is a problem, the curve may be adjusted to
            increase contrast as white-point is approached.

A question to the knowledgeable: InkHueMaps

I promise this to be the last posting for a while.  I like the software 
that much.

I further promise to do whatever I can to help this project!

Question:  From reading the Users Manual (Page 89, just before Section 
8.3.4 - which starts Page 90), it describes the Ink maps.  It even 
states an example and the purpose of the vertical axis.

Alas, this information is insufficient for me to understand the 
explanation, and reading the source code has not helped me at all.

My plea; please show me how to achieve the following in a form of example:

Orange:  1. Increase Dmax to 100% (it looks about 50% now)
             Make the Orange color be more yellowish (and less
             magenta)
          2. Increase the use of the Orange ink vs using Yel+Mag.

Red:     1. Make the ink more yellow and less magenta
          2. Make more use of the red ink and less of Yel+Mag

I realize that requests 1 and 2 above are conflicting, but this way I 
will be able to understand the usage of this important feature.

If desired, I volunteer to enhance the relevant section of the manual.
I believe I may be capable of this task.

Possible Bug; Using Ink Hue Maps

I hope you excuse the (possible) intrusion. Please re-direct me if needed.

Setup: AMD64, 4GB memory, lots of disks, Linux 2.6.37, Gimp 2.6.11,
        Gutenprint 5.2.6, Epson Stylus Photo R1900 - Recent purchase

Print: A version of iT8.7 Reference Target (virtual, following ANSI
        definition. Tiff (8bit), sized to 8.5x11 inches.

Reproduce: Start Gimp,
            Load Tiff Image
            File -> Print with Gutenprint -> Output Tab -> Adjust Output
            Click "{Cyan,Magenta,Yellow,Red,Orange} Map" Enable Button
            Click Close
            Click Print

Output:    See Attachment file.
           [Complains about relevant plot being out of range of 0.0-1.0]

Further:  I can edit the plots any which way I choose, but as long as
           the "Enable" check mark is selected, the error condition is
           induced.

Priority: High;  I must be able (in my imperfect judgment) to use these
           corrections to tune the printer.  Without it, I cannot deliver
           a long delayed project (my fault, of course! :-)

Another Bug (?): "Edge" Printing

Setup:    Linux 2.6.37, Gimp 2.6.11, Gutenprint 5.2.6,
           Epson R1900 printer

Subject:  iT8.7 Reference Target.  Sized to 8.5x11", reduced to 4.11x5,
           printed 4up on 8x10 sheet of Luster Premium Photo Paper.

Configuration:  See attached .gimp/printc-trimmed file

Problem:  Leading Edge image degradation
           Trailing Edge image degradation

Observed: Enabling Quality Enhancement;
           Level 1:  Works properly
           Level 2:  Leading Edge:  Cyan and Light (without
                     Densitometer, estimating) +15R, +20D
                     Trailing Edge: Last inch gradually faded.

Elaborated: Leading edge problem does not exhibit fine banding, "grain"
             is uniform but density is substantially diminished and color
             is severely cyan.
             Trailing edge appears like multipath diminishing; on the
             last inch or so, fine bands are increasingly visible, and
             gray image fades to almost white. Also, print fails to
             completely eject from the printer.

Caveat:     This only happens to the second and fourth print on the
             page.  This means the prints start at 5" from the leading
             edge.  It does _not_ happen on the leading edge (prints
             span 0-5" of the 10" dimension.)

Aggravate:  Switch Color Correction from "Uncorrected" to High Accuracy"

Work Around: Switch to QE=1 reduces/changes the problem greatly:
              LE seems almost perfect but the very leading edge (first
              few scan lines) shows a square tooth pattern; dark=0.016",
              light=0.008", light~0.5*dark.
              However: Going from QE=1 to QE=2 turns the print, overall
              slightly light and cyan.

Priority:    High, unless there is a way to print an 8x10, as a 10x8;
              make the 10" side the leading edge.  This is very good as
              it enables printing 8x10s on 10" paper without waste.
              There is no work-around for cut-sheet paper, other than
              over-sizing (expensive!).

If it will help, I will try to provide some close-up photographs.  I 
cannot place my camera at the moment.

Looking at your printrc, this was at 2880x2880 SW.

I do know about this problem, but unfortunately don't have a fix.
Essentially, quality enhancement uses extra passes to achieve more
uniform printing.  Each level doubles the number of passes.  In
effect, printing 2880x2880 at QE=1 prints as many passes as 5760x2880;
QE=2 prints as many passes as 5760x5760 would, and so forth.

Unfortunately, many (but not all) Epson printers have problems at the
leading and trailing edge of the paper (not the image -- if the edge
of the image is well away from the leading and trailing edge of the
paper, I believe that it works fine, although I haven't tried it in a
while) when the effective resolution is extremely high.  The only
workaround is to refrain from using those very high combinations.  You
may find that 5760x1440 or 2880x2880 with QE=0 (turned off) gives you
the best results near the leading and trailing edge of the paper,
although it may not be quite as good away from the edges.  My
recollection is that the trailing edge has the most problem (fading
out).

I don't think this really aggravates it, although depending upon the
exact colors it may make it look worse.
