WEB ROLL SIZES are also expressed in terms of sheet width, since the web press cuts the paper into sheets at the delivery end. There are five categories of size:

• form webs use rolls that are 8 1/2" wide to print business forms, sell sheets, and other items with a flat trim size of 81/2 x 11".

• mini-webs use rolls that are 11" wide to print brochures, newsletters, and other products that trim to 11 x 17".

• half-webs, which have taken a great deal of work away from sheetfed presses, print on 17" wide rolls to produce eight-page signatures that trim to 17 x 22".

• three-quarter webs also print eight-page signatures that trim to 17 x 22", but from rolls of paper that are 22" wide.

• full webs are for printing 16-page signatures that trim to 23 x 35" from rolls that are 35" wide.

INTERNATIONAL (ISO ) SIZES give the metric measurements for paper as it is used outside North America. Sizes A4 through A1 are roughly equivalent to North America's standard sheet sizes:

A4, 8 1/4 x 11 3/4" (8 1/2 x 11")
A3, 11 3/4 x 16 1/2" (11 x 17")
A2, 16 1/2 x 23 3/8" (17 x 22")
A1, 23 3/8 x 33 1/8" (25 x 35")
