Comparison To Standard Office Paper
Standard office paper has traditionally been designed for use with typewriters and copy machines, where the paper usually does not get wet. With these types of paper, moisture tends to wick through the fibers away from the point of contact to form a disk. For an inkjet paper, this spreading results in the ink spreading out in the fibers to form a large smudge which lacks pigment intensity.
High-quality inkjet printing with dark, crisp lines requires the paper to have exactly the right degree of absorbency to accept the ink but prevent its sideways spread. Many general-purpose office papers of weights around 21 to 27 lb (80–100 g/m²) have been reformulated so that they can be used equally well with both inkjet and laser printers. However, this category of paper is only suitable for printing text, because the ink load is light.
When paper is manufactured, it is formed from a fiber mat that collects on an open mesh screen, which is then dried and pressed flat and smooth. Large areas of inkjet color, such as found in graphics and photographs, soak the paper fibers with so much moisture that they swell and return to their original shape from before pressing, resulting in a wavy buckling of the paper surface.
Double-sided inkjet printing is usually not possible with inexpensive low-weight copy paper because of bleed-through from one side to the other. Heavier weight paper works better due to the thickness of the fibers limiting bleed-through.
These papers are also unsuitable for photographic work because standard office paper is usually not "white" enough. This results in a poor color gamut and leads to colors being described as "muddy".
For all types of paper, the settings in the printer driver must be adjusted to suit the paper, so that the right amount of ink is delivered.

Famous quotes containing the words comparison to, comparison, standard, office and/or paper:
“In comparison to the French Revolution, the American Revolution has come to seem a parochial and rather dull event. This, despite the fact that the American Revolution was successful—realizing the purposes of the revolutionaries and establishing a durable political regime—while the French Revolution was a resounding failure, devouring its own children and leading to an imperial despotism, followed by an eventual restoration of the monarchy.”
—Irving Kristol (b. 1920)
“Clay answered the petition by declaring that while he looked on the institution of slavery as an evil, it was ‘nothing in comparison with the far greater evil which would inevitably flow from a sudden and indiscriminate emancipation.’”
—State of Indiana, U.S. public relief program (1935-1943)
“We don’t want bores in the theatre. We don’t want standardised acting, standard actors with standard-shaped legs. Acting needs everybody, cripples, dwarfs and people with noses so long. Give us something that is different.”
—Dame Sybil Thorndike (1882–1976)
“The office of the prince and that of the writer are defined and assigned as follows: the nobleman gives rank to the written work, the writer provides food for the prince.”
—Franz Grillparzer (1791–1872)
“To give money to a sufferer is only a come-off. It is only a postponement of the real payment, a bribe paid for silence, a credit system in which a paper promise to pay answers for the time instead of liquidation. We owe to man higher succors than food and fire. We owe to man.”
—Ralph Waldo Emerson (1803–1882)
