Image Quality
Displaced or Fragmented
Image Distorted images. Displaced images. See digital defects. - -
Dropout Areas of missing ink pixels usually in mid-scale density areas. Image may look grainy. IQ 6 TP 11
Duplex
Ghosting Faint image which shows as a gloss differential from the previous print or previous area repeated onto a subsequent print. IQ 19 TP 4 ( TP 2
to TP 10 )
Gloss bands (process or
cross process direction) Lines or bands of irregular gloss, most noticeable in solid areas, in process or cross process direction. IQ 16 , IQ 17 TP 5 ( TP 2
to TP 10 )
Gloss irregularities Random changes in gloss level causing an irregular, uneven gloss or matted appearance, most noticeable in solid areas. IQ 18 TP 5 ( TP 2
to TP 10 )
Grainy Speckled or sand-like appearance in what is meant to be a smooth area. IQ 6 TP 11
Ink discolouration Color shift noted on the print relative to other prints of the same image. May be localized in process direction wide bands:
•
If the defect is across some of the printheads and matches any in Figure 3 , go to the IQ 14 Some Colours Uneven RAP.
• If the wrong colours are printed, Figure 9 , go to the IQ 15 Wrong Colour RAP.
• If the defect is across all colours and matches any in Figure 1 , go to the IQ 13 All Colours Uneven RAP.
IQ 14 , IQ 15 , IQ 13 TP 10 ( TP 2
to TP 10 )
Ink transfer See residual image. - -
Irregular line See jagged lines. - -
Irregular process direction
streak See banding. - -
Irregular text See jagged text. - -
Jagged line Lines meant to be straight in the cross process direction are blurry, jagged or have relative misalignments. May be localized at
the 3 boundaries between printheads. Pixel position may be slightly incorrect in the process direction. IQ 5 TP 1
Jagged text Text meant to be correctly formed in the cross process direction is blurry, jagged or has relative misalignments. May be local-
ized at the 3 boundaries between printheads. Pixel position may be slightly incorrect in the process direction. IQ 5 TP 1
Lead edge smear See smudges, smears -
Light image The image is visible on the print, but with insufficient overall density:
•
If the defect is across all colours, go to the IQ 13 All Colours Uneven RAP.
• If the defect is across some of the colours, go to the IQ 14 Some Colours Uneven RAP.
IQ 13 , IQ 14 TP 1
Light lines in the cross pro-
cess direction Image dependent increasingly faint localized bands in the cross process direction, Figure 10 . IQ 13 TP 1
Lines Lines of missing ink - see deletions.Lines of extra ink - see smudges, smears. - -
Marks See spots of ink.See smudges, smears. - -
Missing colours See deletions. - -
Missing images See partial images. - -
Non uniformity See banding.See dropout.See light Image. - -
Offsetting See residual image. - -
Oil on output Spots or splatter of oil on the output. IQ 21 TP 1
Partial images Either the complete or portions of the image are missing. IQ 12 TP 1
Print damage Creases, curls, cuts, folds, wrinkles, or embossed marks on the print. Also see wrinkling. IQ 2 N/A
Repeat images • Gloss - see ghosting
• Ink/density - see residual images
- -
Residual image Ink from a previous print is deposited onto subsequent print. See also blocking. IQ 23 TP 10 ( TP 2
to TP 10 )
