  2. Offset printing - Wikipedia

    en.wikipedia.org/wiki/Offset_printing

    Offset printing is a common printing technique in which the inked image is transferred (or "offset") from a plate to a rubber blanket and then to the printing surface. When used in combination with the lithographic process, which is based on the repulsion of oil and water, the offset technique employs a flat (planographic) image carrier.

  3. Set-off (printing) - Wikipedia

    en.wikipedia.org/wiki/Set-off_(printing)

    The problem can occur with most types of printing, and is avoided by the use of slipsheets between copies (so any ink transfer occurs onto discardable paper) or anti-set-off spray powder. The term in offset printing also refers to the unwanted transfer of ink to rollers and friction points throughout the printing press. Ink that is not properly ...

  4. Waterless printing - Wikipedia

    en.wikipedia.org/wiki/Waterless_printing

    Waterless printing yields higher ink densities and a broader color spectrum than conventional offset printing does. Waterless plates used on sheet-fed presses are commonly rated for runs of 100,000 to 200,000 impressions. The plates designed for use on web-offset presses can yield 300,000 to 500,000 impressions.

  5. Pad printing - Wikipedia

    en.wikipedia.org/wiki/Pad_printing

    Pad printing (also called tampography) is a printing process that can transfer a 2-D image onto a 3-D object (e.g., a ceramic pottery). This is accomplished using an indirect offset ( gravure ) printing process that involves an image being transferred from the cliché via a silicone pad onto a substrate .

  6. Prepress - Wikipedia

    en.wikipedia.org/wiki/Prepress

    Prepress is the term used in the printing and publishing industries for the processes and procedures that occur between the creation of a print layout and the final printing. The prepress process includes the preparation of artwork for press, media selection, proofing, quality control checks and the production of printing plates if required.

  7. Offset ink - Wikipedia

    en.wikipedia.org/wiki/Offset_ink

    It is crucial that offset ink resist water-in-ink emulsification (i.e., repel rather than absorb water). It also should withstand degradation by the fountain solution that covers the non-printing areas of the engraved plate. Offset ink needs to be very rich in pigment so that its full color vibrancy is perceptible, even in minute quantity. [2] [3]

  8. Anti-set-off spray powder - Wikipedia

    en.wikipedia.org/wiki/Anti-set-off_spray_powder

    Similarly, spray powder is not generally used in sheet-fed (silk) screen-printing, ink-jet or toner based digital printing. In the UK, many Carrom players use a version of anti-set-off spray powder from the printing industry [ citation needed ] which has specific electrostatic properties with particles of 50 micrometres in diameter.

  9. Trap (printing) - Wikipedia

    en.wikipedia.org/wiki/Trap_(printing)

    Thinner traps are less visible. Therefore, the trap width is set to a strict minimum, dictated by the maximum amount of misregistration of the entire workflow up to the press. When printing at 150 lpi, traps are usually between 1/150 and 1/300 inch (0.48 pt and 0.24 pt, 0.16 mm and 0.08 mm). These values are usually multiplied by 1.5 or 2 when ...
