Abbreviated "fpm," and describes the speed of a papermaking machine in terms of how many feet per minute the forming web of paper traverses the length of the machine.
felt
Woven, endless belt made of wool, cotton or synthetic materials used to transport the paper web on the paper machine, during manufacture. Felts act as conveyors while at the same time removing water from paper as it progresses through the paper machine.
felt finish
(1) Surface which is achieved at the wet end of the Fourdrinier machine by using felts of a distinctive weave rather than standard or regular wove felts. (2) On a Yankee papermaking machine this finish is accomplished by pressing the felt against the paper under pressure. (3) Felt finishing can also be obtained after the manufacturing process by impressing the felt against the paper under pressure. Also felt mark.

fine papers
Large category of paper that includes those grades used for writing, printing and cultural purposes.
finish
The most important physical property of paper. The term finish has a broad meaning. It describes surface contour and characteristics measurable by smoothness, gloss, absorptiveness and print quality. Surface character of paper differs greatly. Finish of paper can be aesthetic. It can be functional. The finish of a text or cover paper is more often than not selected by a designer to express an aesthetic view. High fidelity halftone illustrations require a glossy enamel finish. Finish may be a top-priority choice. Or it may be secondary. If high-bulk paper weight is necessary, a low finish, antique paper must be acceptable. The choice of finishes for letterpress or gravure is subject to the limitations of these print methods. Offset lithography does not impose finish limitations since it is capable of printing on almost all surface conditions. Finishes originating during the papermaking process may be described in order of their smoothness--roughest to smoothest. Antique describes the roughest surface. It gives maximum bulk-to-weight ratio. Antique papers are soft to touch. They are used for high-bulk purposes and in those cases where the surface characteristic is required. Papers with a smooth finish are described as having an eggshell finish. It is selected by printers because it is easier to handle after printing. It possesses a greater degree of ink absorbency; which means it has less tendency to set-off. Further smoothing of the paper results in a machine finish or an English Finish. The latter represents the highest possible finish that can be produced on a paper machine. The levels of finish--antique, eggshell, vellum, machine and English--may be measured with instruments in the laboratory. Paper machines are capable of making finishes other than those discussed. A felt finish paper possesses a textured surface provided by marking felt, or by use of rolls with an embossed surface at the press section of the paper machine. In each case, a design is impressed into the paper web while it continues to carry a high percentage of water. Felt finishes so produced are applied to text, cover and superior quality wedding paper. Aside from printing requirements, finishes are chosen for their aesthetic appearances to help designers achieve purpose. Specific end-use requirements may dictate that a paper's surface possesses properties that repel water or grease. Plastic coated cover papers for example resist soiling of any kind, water and grease.
finished art
Art in such forms as handlettering, charts, color blocks, illustrations, photographs that are ready for camera.
finishing
Covers a wide variety of processes used to finish and package paper.
finishing broke
Discarded paper resulting from any finishing operation.
flag
A strip of paper protruding from a roll or skid of paper. May be used to mark a splice in a roll of paper or used to mark off reams in a skid.
flat
Assembled composite of negatives, usually on goldenrod paper, ready for platemaking.
flat bed
Press with flatbed and an impression cylinder.
flat forms
Standard dimensions for flat forms include nine sizes that cut without waste from business paper size 44" x 34". Or, which when combined in multiples of 2, 4, 8, 16, 32 or 64, will form press sheets that will cut without waste from standard-size business papers.
flat screening
Shading effect on an area of a form by screening over that part where the negatives are made.
flat tones
Areas of dot formation that contain a single tone value.
flats
Paper coming from the paper mill in flat sheets, larger than 17" x 22".
flexography
Letterpress printing using relief plates on direct presses. This process of printing uses rubber plates and special aniline inks.
flint glazing
Flint glazing is still another method of achieving high gloss finish. In the process, a coated-one-side paper travels slowly over a supporting surface with its coated side in a direction perpendicular to the direction of web travel. The web moves very slowly so that a smooth stone or stone burnisher has time to make a number of passes over the paper's surface and polish it to a high glaze of patent leather intensity.
flint paper
Highly glazed, brightly colored paper coated on one side.
floating load
Paper loaded into a freight car in a manner that allows it the freedom to shift slightly without damage when the car is bumped in transit.
flock papers
Decorative paper sized on one side and dusted with fibers of rayon, wool or cotton on the other in imitation of velvet or suede.
flong
Absorbent paperboard which when impressed and dried becomes a matrix for preparing stereotypes.
flooding
In reference to printing, when the ink flows onto a printing plate because the ink fountain has not been set properly.
flow
In reference to printing ink, the extent to which it levels out when still a liquid.
fluorescent paper
Paper that has been manufactured with the addition of fluorescent dyes which give the brilliance that appears brighter when viewed in natural daylight. A variety of whites are produced including green-white, cream-white and blue-white. All are high-white with a large brightness measuring number in the middle 90s. Most popular is neutral white for paper surface efficiency.
flush cover
Cover of a book that has been trimmed to the same dimensions as the text papers.
flush paragraphs
Paragraphs without indentations.
flying paster
Machine which connects the lead end of a new web of paper to be pasted to the tail end of the previous web without ceasing operation.
flyleaf

fold marks
Short line printed on a business form indicating where it may be folded.
folder
Device at delivery end of a press or collator to fold continuous forms.
folding bristol
Bristol board with good folding ability and printability.
folding endurance
Capability of paper to resist folding determined by the M.I.T. tester or the Schopper Folding Endurance Tester. Also known as fold resistance. For the explanation of the test to determine foldability of paper and board, see Chapter 6.
folio
A ream or sheet in its full size, e.g. 17" x 22", 25" x 38". When used in connection with books, means the sheet has been folded once, producing four pages.
font
Assortment of type characters of a particular size and style.
formation
Visible physical property of paper influenced by the extent of fiber refining. The term is descriptive of the paper's fibrous structure and point-to-point (caliper thickness) uniformity or lack of it in the distribution of the fibers. Increased refining improves the quality of formation. Formation is a relative property, determined by end usage. The properties of levelness and smoothness are dependent upon the paper's uniform formation. When the formation is wild, the paper will not possess good qualities of levelness or smoothness.
foundry proof
Final proof before sending a letterpress form to the electrotyper.
fountain solution
Solution used in the water fountain of offset presses; usually contains water, gum arabic and an etch.
four-color process

free-flowing carbon
Non-processed carbon in a continuous form held in place by crimps along each edge.
free-sheet
The word "free" in this context means free from mechanical pulp. The definition issued by the U.S. Bureau of Census and by the Custom Cooperation Council for world trade permits up to 10% mechanical pulp content in paper termed "free sheet". The definition used by some individual buyers requires the fiber content to be totally free of mechanical pulp, i.e. 100% chemical pulp.
friction glazed
High finish applied to paper by passing the web through chilled iron rolls, one large and one small, revolving at different peripheral speeds. The rolling friction between the two rolls produces a highly glazed surface.
fugitive colors
Inks which are not permanent, which fade or change color when exposed to light.
full body imprint
Form with no limit on the area to be imprinted.
full coated carbon
Carbon paper coated completely on one surface.
furan
