a) A type of offset printing plate that uses aluminium as its base material, and can be coated with a variety of photosensitive or heat-sensitive layers to carry the image.

b) It is used in an imagesetter. Negative is characterized by the areas carrying image information for print being transparent and the non-printing areas are black. Positive are those with areas carrying image information for print in black and the non-printing areas are transparent.

c) Process used for quality control in prepress and printing regarding colour reproduction, register, text and image layout, or as a sample for the production run.

d) They are produced photomechanically from films that have been exposed, for instance, using colour foils.

e) Producing page proofs directly from stored digital information without creating a film negative. Some examples are prints from laser, ink-jet, thermal transfer and dye sublimation.

f) They are produced using an NIP-technology based colour printer from the digital data file. The expected print result on a production press should be reproduced as accurately as possible. This is supported/achieved by using colour management systems.

g) This refers to a colour-proofing system which is used to make proofs for offset and gravure (positive), but also for flexo and newspaper print (negative).
