Grain direction is the orientation of fibres with respect to the long edge
of the paper. For example, in an A4 sheet, the fibres of a long grain
sheet are parallel to the 297 mm dimension of the page (the pages of a
short grain sheet are parallel to the 210 mm dimension).
Weak image (on an offset print) with a granular look caused by ink
becoming waterlogged and caked.
The weight in grams of one square metre of paper (abbreviated to gsm).
The mix of cyan, magenta, yellow and black that produces a neutral grey
across the tonal range.
The 10 mm lead edge of the sheet that is rendered unprintable by
grippers (the row of clips that holds a sheet of paper as it moves
through an offset press).
The weight in grams of one square metre of paper. Also called
grammage.
The blank space, or inner margin, from the printing area to the binding.
A continuous tone image that has been reproduced with groups of small
dots.
To produce continuous tone images on a printing device, the image must
be broken down into a series of dots of various sizes and colours, called
a halftone screen.
The result when a dark coloured object knocks out a coloured
background that is composed of more than 30 to 70% of one toner
colour on a xerographic printer.
A recurring, unplanned spot appearing on an offset printed image
caused by dust, lint, dried ink or paper stuck to the blanket.
The lightest area in an image or photograph.
The name of colour, such as green, blue, purple or orange. One of the
three characteristics that describe colour (along with saturation and
value).
Short for International Colour Consortium. An industry body that has
been set up to create a common framework for colour management.
A file that describes how a particular device (eg, printer, display or
scanner) reproduces colour (ie, its gamut or colour space).
Short for Image Colour Matching. The colour management framework
that is used in the Windows environment. ICC profiles in the Windows
environment have a .icm extension.
The positioning of individual pages on a signature (or press sheet) so
that after printing, folding and cutting, all pages will appear in the
proper sequence.
