== Proofs ==

Always supply a proof of the very latest version. If possible, a 1:1 scale version of the proof should be given. If the proof is not 1:1 scale, this should be clearly marked.

Digital proofs can be divided into two groups, content proofs and
contract proofs.

=== Content proof ===
The proof is produced using a printer or copier. The proof can be used to make a rough check on the accuracy of the text and colouring (“red is red”), but the colours do not correspond to the printed end product.

=== Contract proof ===
By contract proofs is meant proofs which can be used to check colour tones. The proof is made on a proofer calibrated for print quality. The validity of a contract proof must be checked by measuring a color
bar, like Fogra Media Wedge, which has been printed on the proof. The proof is acceptable, when all tolerances are passed. Equip the proof with the OK-label of an accepatable measurement.
