Factors Governing Inkjet Print Quality
Many times when poor print quality is encountered it is assumed the ink is the
cause. More often than not, the problem can be the wrong paper, or the printer
setup is improperly set for the type of job on hand. These factors can have a
dramatic effect on the print quality and should be considered whenever poor
print quality is experienced.
Paper and Inkjet printing
Paper or media on which you print has a basic job to dry the ink as soon as it
comes in contact with it. The way paper absorbs ink is what we are concerned with.
The terms used to describe problems associated with paper are:
Blooming
This term refers to effects seen when the size of the original dot has expanded
outward like a flower making the print fuzzy and blurred.
Wicking
This term is used when the ink is absorbed by the fibres in the paper creating
a spider web effect.
Bleeding
This is seen when colours are right next to other colours or black areas and
they start to mix, creating a muddy undefined look in that area.
All of these problems are caused by the ink sitting on the surface, it is wet
and problems can occur. Laser or Photocopy paper is not suitable for inkjet
printing, unless it is specified on the wrapper for inkjet use and even then,
some are better than others. The Majority of inks are dye based and will fade if
exposed to constant light. In direct sun light some prints will fade within 90
days.
Hi Resolution Paper
This type of paper will improve the quality of any inkjet printed image, because
the surface has a chemical coating which causes the ink to combine with it and
stops the ink from bleeding into the paper.
Photo Gloss Paper
This has the same effect as hi-resolution paper, but has a gloss finish and is
available in various thicknesses.
Printing On Specialist Paper
When printing on specialist papers remember to change the printer settings to
match.
