In contrast to a proof, a press proof is created using films or CTP printing plates on special press proof machines with the same colours and parameters as the subsequent production print. Press proofs are rarely used today for cost reasons.
The printing form is a central element in the printing process; it contains the image to be printed, i.e. the information that is transferred to paper during the printing process. The type, manufacture and function of the printing form vary depending on the printing process. However, it forms the basis for the reproduction of text and images in print. Four types of printing forms Printing forms can be divided into four main categories, which correspond to the classic printing processes: relief printing, intaglio printing, planographic printing and gravure printing. In …
The printing plate is an important element in printing technology and is mainly used in flat printing such as offset printing. It contains printing and non-printing areas and transfers the printing information to the printing material. This is usually done indirectly, i.e. via a rubber blanket cylinder. The print motif is the correct way round on the printing plate, reversed on the rubber blanket, and the correct way round again on the paper. Modern printing plates are usually made of anodised aluminium with a light-sensitive coating. This coating is directly …
Process colours are the colours that are created in printing when several colours are printed on top of each other (usually using halftone screening).
In four-colour printing, this colour is composed of cyan, magenta, yellow and black. With these four colours a very large number of colours with different tonal values can be printed.
To “proof” means to produce a proof or have a proof produced.
A proof (correct: contract proof) is an ISO-certified testing device for the graphic arts industry. A proof simulates the colourfulness of offset or gravure printing in a colour and legally binding manner within the narrow tolerances of ISO 12647-7.
Proof cheap is a typical search term that people use in search engines to search for a cheap, colour and legally binding proof. But what makes a cheap proof? A proof becomes a proof that it is produced according to the specifications of the latest revision of the proofing standard ISO 12467-7 and that it is within the tolerances of this standard. The current revision is ISO 12647-7:2016, which has been tightened even further with this standard and has been supplemented by a certified edition of spot colours such as …
The proof costs, i.e. the costs for a proof, are usually calculated according to the format to be proofed and the quantity of proofs.
