Term Description
Displaced or Fragmented Distorted images. Displaced images. See digital defects.
Image
Dropout Areas of missing ink pixels usually in mid-scale density areas. Image may look grainy.
Ghosting Faint image which shows as a gloss differential from the previous print or previous area repeated onto a subsequent print.
Gloss bands (process or Lines or bands of irregular gloss, most noticeable in solid areas, in process or cross process direction.
cross process direction)
Gloss irregularities Random changes in gloss level causing an irregular, uneven gloss or matted appearance, most noticeable in solid areas.
Grainy Speckled or sand-like appearance in what is meant to be a smooth area.
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
• If the wrong colours are printed,
• If the defect is across all colours and matches any in
Ink transfer See residual image.
Irregular line See jagged lines.
Irregular process direction See banding.
streak
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.
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.
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
• If the defect is across some of the colours, go to the
Light lines in the cross pro- Image dependent increasingly faint localized bands in the cross process direction,
cess direction
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.
Partial images Either the complete or portions of the image are missing.
Print damage Creases, curls, cuts, folds, wrinkles, or embossed marks on the print. Also see wrinkling.
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.
