8. When you are satisfied with the graytone image
quality, print one or two cards with Wedge_1.bmp
to test for ribbon wrinkling. This image is the
densest possible process black, meaning that on
all three passes (Y, M and C) one end of the
printhead is fully “on”, while the other end is
“off”, a sure way to induce wrinkling if there is
the slightest tendency. Wrinkling may be a head
angle issue (more clockwise than it should be),
but it may equally result from too high a ribbon
torque, page TN4-x.
Check the torque before readjusting
the head .
9. When you are satisfied that ribbon wrinkling is
under control, print one or two cards with
Wedge_2. bmp , this being the same triangle flipped
so that its black area starts full width.
10. As a final test, run Portraits.bmp to test for skin
tone realism, etc.

on the card.
Vertical (Y) Offset (Pixels): Moves the image up
and down. Used to center the image on the card.

characterized in manufacture at a specific speed.
Changing this speed will force the printer to use
