Voluntary third-party forest certification began in the 1990s in response to market concerns about forest management and illegal logging, primarily in developing countries. The SFI program was launched in 1994 as one of the U.S. forest sector’s contributions to the vision of sustainable development established by the 1992 United Nations Conference on Environment and Development. Its original principles and implementation guidelines began in 1995, and it evolved as the first SFI national standard backed by third-party audits in 1998. Today, SFI Inc. is an independent, non-profit organization responsible for maintaining, overseeing and improving a sustainable forestry certification program that is internationally recognized and is the largest single forest standard in the world. The SFI 2010-2014 Standard is based on principles and measures that promote sustainable forest management and consider all forest values. It includes unique fiber sourcing requirements to promote responsible forest management on all forest lands in North America. SFI certification also extends to the market. When they see the SFI label on a product, consumers can be confident they are buying wood or paper from responsible sources – whether it is reams of paper, packaging or two-by-fours.
SGML (Standardized Generalized Mark-Up Language)
SGML is one of the newer languages for marking text for a variety of purposes, including typesetting and disk publishing. A well-designed SGML scheme enables the publisher to mark text just once for multiple uses.
Dark area of a continuous-tone image or its halftone reproduction.
To decrease in color strength, as when halftone dots become smaller.
Press that prints on individual sheets of paper rather than on paper from a roll.
To print one side of a sheet of paper with one plate, then turn the sheet over and print the other side with another plate using the same gripper and opposite side guide.
For large signatures the center or gutter margin is varied according to the position of the page in the signature and the bulk of the paper.
An ink that is buttery and does not flow freely.
The undesirable condition is which the printing on the reverse side of the sheet can be seen through the sheet under normal lighting conditions.
A guide on the feed board to position as it feeds into the front guides before entering the impression cylinder.
A large printed sheet or form after it has been printed, folded and trimmed down to page size.
A halftone of a subject with all of the background removed.
The treatment of paper which gives it resistance to the penetration of liquids or vapors.
A platform support for a pile of cut sheets of paper.
Cutting printed sheets or webs into two or more sections by means of cutting wheels on a press or folder.
An alphabet of SMALL CAPITAL LETTERS available in most roman typefaces approximately the size of lower-case letters. Used in combination with larger capital letters.
Measure of paper surface irregularities; affects the appearance of printing by affecting how the ink lays on the surface of the sheet.
Halftone dot with considerable fringe which causes dot gain or sharpening in printing or photography.
Descriptive of the consistency of paste inks.
Instrument for measuring color for CIE color spaces. It is more accurate than most color colorimeters.
The Spectrum digital halftone proofing system provides consistently accurate proofs. Its Squarespot thermal imaging produces solid density, tone curves and color that are consistent from proof to proof. Spectrum proofing delivers the highest proof-to-plate consistency in the industry by imaging proofs using the same input file, resolution line screen, screen angle, spot function and thermal imaging system used to image plates. The Spectrum allows you to select the receiver onto which the color media is imaged to enable you to see how the paper on which you will print affects the appearance of the printed piece. The Spectrum is superior to a matchprint in quality and accuracy.
A book bound with wires in spiral form inserted through holes punched along the binding side.
Smallest visible point that can be displayed or printed. The smallest diameter of light that a scanner can detect, or an imagesetter or printer can image. Dot should not be confused with spot.
Printed color other than black, but not one of the three process colors.
An Aattachement designed to remove the static electricity from the paper to avoid ink set-odd and trouble with feeding the paper.
Step and Repeat
The procedure of mulitple exposure using the same image by stepping it in position according to a predetermined layout or program.
A profreader's mark, written in the margin, signifying that copy was marked for correction should remain as it was.
A digital screening process that converts images into very small dots (14-40 microns) of equal size and variable spacing. Second order screened images have variable size dots and variable spacing. Also called Frequency Modulation Screening.
Paper or other material to be printed.
In lithography formerly used as the plate material and present used by artists as an art medium. In letterpress, the bed on which metal type is leveled and locked up.
One of three variables in alphabet design; refers to distribution of visual "heaviness" or "slant" of the character.
Type set on typewriter composing machines.
Strike-through varnish is a technique in which a dull or matte varnish is applied on all areas of a coated sheet except for the areas that are intended to be glossy. Then, a high-gloss aqueous coating is flooded over the sheet. As it cures, the varnish strikes through the aqueous coating to achieve a dull finish wherever varnish was applied and the areas where the varnish was not applied appears glossy. This process is more cost-effective than a dry-trap varnish, but it does not achieve the same contrast.
Process of assembling pieces of film containing images that will be carried on the same plate and securing them on a masking sheet that will hold them in position during the platemaking process; much of the function is now being performed by computers.
In image assembly the positioning of negatives (or positives) on a flat to compose a page or layout for platemaking. In printing ink stripping on ink rollers prevented by plastic or copper coated steel rollers in the ink roller train.
