Digital BW, The Print

Roy

This is the first time I have noticed this on an image but then this is also
the first I have printed with substantial areas of deep black ­ all the
background should be dMax and consistently so.  It is interesting to note
that when the printer gets to a portion of the image that is not 100% black
the problem quickly disappears ­ by this I mean that if the pure black is
broken by a portion of the image that is not pure black and then followed
(in order of printing) by another area of pure black, the second area prints
ok.  I printed the image with the Epson driver and BO and had no problems.
QTR prints the image from right to left while the Epson driver goes from
left to right.  So QTR struggles with the lower right background area or,
when the image is rotated before printing, the mid left side (in terms of
the original perspective).  With the rotated image, QTR has no problem with
the background once it has printed through the orchid itself.  I have added
the original image to the web page so that you can get a sense of the entire
image.  Unfortunately my scanner doesn¹t scan the end effect that well to
show you but it looks as thought the print was brushed/scratched while the
ink was still wet ­ in the affected areas.

Thanks for the help

Steve

Hi Steve,

I'm not sure what more I can add, but the weird patterns you see are
the way the microweave works.  It is strange and the exact gray value
being printed does affect it showing during the lay down.  Part of the
reason using QTR shows this more than the Epson driver is that fewer
number of inks are being used.  In the cases I've seen when all the
passes are finished the effect is completely covered up.  But it sounds
like you are left with some kind of scratch-like banding.

Have you always had the problem?  Changed inks recently?  Is it
mage dependent?  Slightly tonal changes or just adding a small amount
of noise may help.
