satin finish

A smooth delicately embossed finished paper with sheen.

saturation

The attribute of color that describes its degree of strength and its departure from gray with the same lightness.

The illuminator that is used inside the scanner to light the original during content analysis.

scatter proof

A proof of one single picture or a group of images made to check color and image quality.

SCITEX

Abbreviation for Scientific Textiles – Scitex evolved into one of the largest suppliers of prepress equipment, was bought by Creo which itself was later purchased by Kodak.

score

A crease put on paper to help it fold better.

scoring

Creasing paper mechanically so it will fold more easily. This is usually necessary when the paper is even moderately stiff or when the fold goes across the grain.

scratch off printing

Scratch printing or scratch off printing is the process of applying a foil to specific areas of a document. The foil can be removed with the edge of a coin or a fingernail to reveal the information printed beneath it. The process is often used on giveaway and contest printed materials, such as lottery tickets.

Screen

Dainippon Screen, formed in 1943, is one of the largest companies supplying scanners, workflows and output devices to the graphic arts.

screen angle

The position of the two rows of halftone dots relative to degrees of a circle. When outputting the four films of reproduction, the dots of each process color are placed at a distinct and different angle, one to another. Usually, the major strong colors of cyan, magenta and black are placed at a distance of 30 degrees, although some software generates other screen angles.

screen curve

A graph that illustrates the relationship between the stored gray level for a pixel and the dot size that will result on output. Screen curves are established during linearization of an output device.

screened print

A photo print made by using a halftone negative; also called a Velox.

screen fonts

Computer files containing the bitmap outlines of digitally rendered typefaces for display on a computer monitor. Screen fonts offer high fidelity to the printed output.

screen frequency

An expression of the number of lines or dots per unit of length in a screen for producing a halftone screen.

screening

Screening is the technique that is used in printing to simulate tints or continuous-tone images such as photographs using dots. Almost all printing technologies such as offset, gravure or inkjet printing simulate shades of colors using dots.

screen printing

A fairly simple and inexpensive printing technique that is well suited for low volume printing on highly irregular surfaces, like binders or clothing. The colors of screen printing tend to be vibrant and long-lasting which also makes the process suitable for outdoor displays and printing on frequently used items. Billboards and t-shirts are almost always printed in this process. Due to the long time the heavy ink takes to dry as well as registration problems, screen-printing may never be a viable option for high-quality print jobs.

screen ruling

A measurement equaling the number of lines or dots per inch on a halftone screen.

screen tint

A halftone that contains a uniform dot size over the entire area.

security printing

The segment of the printing industry that handles printing banknotes, passports, identity documents, driver’s licenses, vouchers, lottery tickets but also packages for luxury or pharmaceutical products.

self cover or self-cover

The cover of a book or booklet that is printed using the same paper grade and weight as the inside pages. This can be done to assure that a slim booklet can lay flat but is is also a good way of reducing cost.

serif

– Thin lines added to the end of a letterform’s stem and stroke.

– A typeface that uses serifs. According to most typographers, serif typefaces are ideal for large blocks of text because the serifs improve readability.

service bureau

An organization that provides output from digital files, usually to a PostScript imagesetter. Service bureaus are contrasted to trade shops, which ordinarily use a combination of manual and electronic prepress equipment to output and assemble film.

set off

A printing problem that occurs when wet ink from the printed side of the sheet transfers to the back of the sheet above it.

set-off spray

A dry or liquid spray attachment on presses to prevent ink from transferring from the top of one printed sheet to the bottom of the next. It is also called anti-offset spray.

set size

The width of the type body of a given point size.

shading

To change the brightness or color of parts of a graphic image to simulate a three-dimensional depth.

shadow

The darkest part of an image, usually with the density at or near maximum density.

shape

An attribute of an image that gives it the three-dimensional appearance. For example, the cyan separation gives an apple its three-dimensional appearance by printing a minimum amount of cyan in the front and an increasing amount of cyan around the side of the apple.

sharpen

To make halftone printing dots smaller. Using negative separations, sharpening is accomplished with dot etching. Over exposure will also sharpen the negative films. When positive working plates are made using positive transparencies, sharpening happens automatically and the size of the printing dots are reduced by 5%. This sharpening is called negative dot gain.

sharpness

The term that describes the appearance of the image edges in a picture, photograph, video display, proof or anywhere images are seen. As the image edges are sharpened, more detail will be visible. Unsharpened image edges are fuzzy and appear ‘out of focus’. The clearer cut the image edge, the sharper and ‘in focus’ the image is. Edge sharpness can be increased with unsharp masking.

sheet

A single piece of paper.

sheet work

See sheetwise

sheetfed press

A printing press that feeds sheets of paper, rather than a continuous paper roll or web. Sheets of different sizes can be printed on the same press.

sheetwise

– The layout of images in a way that requires the use of separate plates to print the front and back of a sheet.
– The printing of two different images on two different sides of a sheet of paper by turning the page over after the first side is printed and using the same gripper and side guides.

shingling

A technique used to prevent creep or push-out in a saddle stitched (or to a far lesser account perfect bound) book made up of a great number of pages of thick paper.

The above drawing demonstrates the problem: once a publication has been trimmed, the inner pages are narrower than the outer pages. This makes the layout shift towards the outer edge and things like page number may actually disappear. To compensate for this inevitable fact, the content of the pages is gradually moved towards the spine for the inner sections.

short ink

Ink that is smooth and creamy but does not flow freely.

shortcut

A pointer file that actually represents another file. This word is only used on Windows systems. On Macs, the same pointer file is referred to as an ‘alias’.

short grain web press

A web press that uses printing plates whose long dimension is along the cylinders.  For long grain web presses the long dimension is around the cylinders. With web presses, the paper grain is always parallel to the direction of the movement of the paper. This means short grain cylinders are smaller than long grain cylinders.

short-run

Four-color print runs of 1000 or fewer copies.

show-through

The effect of one side of a sheet of printed paper showing through to the other side. This usually occurs on thin newspaper or magazine printing paper. An ‘off-white’ type of paper is often used to help reduce this in thinner paper stocks.

slug

– In layout applications such as Adobe InDesign, the slug is an area outside of the trim and bleed area that can be used by the designer to add comments or other information related to the publication. It is not visible in the final printed pieces since it disappears when the document is trimmed to its final size.
– In typesetting, a slug was a line of type in one piece, as produced by a Linotype or other typesetting machine from the 19th or 20th century,

slurring

The smearing of the halftone dots on the press sheet in the direction of the travel through the press. Slurring is caused by paper slipping during the impression stage. It makes the dots look like little comets and causes dot gain.

spadea

A separately printed, unbound broadsheet that is folded around a newspaper, magazine or other periodical. The spadea can also be wrapped around one of the publication’s sections, such as the sports section of a newspaper. This page is not as large as the other pages of the publication, so it appears as a partial page or flap over the front and back. Spadeas are used for advertising and work well since they immediately draw the attention to the reader. This special sheet is also called a spadia, spadea fold or spadea wrap.

specialty printer
