PAPER Continued
Varieties of Paper -
Printers classify varieties of paper by name. It is useful to know
broadly what they are.
Uncoated Cartridge
A strong matte paper; not always pure white. Pleasant as a surface to
read from. Good for continuous text and simple line drawings. Usually
too rough a surface for halftones unless it has been smoothed in
manufacture (machine finished), in which case it will probably have
lost some of its opacity and bulk.
Coated Cartridge
A paper that has been coated with china clay to give greater
smoothness. Usually whiter than uncoated papers. Gives excellent
halftone reproduction. Highly polished versions will reflect light
badly but matte surfaces avoid this and still give good halftone
reproduction. Matte coated cartridge used in a laser printer gives a
good quality original for offset plate-making.
Art Paper
Sometimes called "super calendered (SC)". A very glossy paper with a
highly polished coating of china clay. Originally intended for the
reproduction of halftones from metal blocks. Reflects the light badly
and often feels unpleasantly slimy.
Antique
Uncoated with a matte, or even a rough, surface. Can be very pleasant
to read from, with a comfortable feel. Some versions are made to be
very bulky. If the surface is very soft or fluffy the printer may have
difficulty using it on an offset press.
Writing Papers
Writing papers are described as "wove" or "laid" depending on the type
of wire-covered roller used to squeeze out the water from the pulp
during production.
"Wove" papers usually have an even surface with no obvious pattern
visible in the paper itself if held up to the light.
"Laid" papers sometimes feel slightly ribbed and have a clear pattern
of horizontal lines, crossed by more widely spaced vertical lines when
held against the light. The horizontal laid lines usually run across
the grain.
Newsprint
As the name implies it is meant for newspapers. It is therefore cheap
and lightweight, but tears easily and fades quickly. Not suitable for
anything that has to survive for very long.
Copying Paper
The surface of copying paper is specially finished to accept the toner
used in copying machines. It is not particularly pleasant to handle,
so unless a publication is to be produced entirely on a copying
machine it is better to use a more general printing paper.
A couple of recommendations:
If you are preparing your publication to be sent to a printer for
offset press printing, use a 70 lb heavily coated paper in your laser.
The output will be very sharp but the image will not bind into the
paper surface well so your originals must be handled with care.
If you are doing a short run on your own laser, use a writing paper
specially made for lasers (not photocopier paper!) in 24 to 40lb
stock, but don't try to reproduce halftones on this type of paper.
