5.

The area with extremely high light can be netted, but large areas should not be netted, and dark areas should be preserved.
Comparison of traditional proofing and digital proofing techniques
Traditional Proofing Digital Proofing
The color of the relative printing effect is poor, the color difference is good, and the color difference is small
Image reproduction performance
Good image resolution (overprint accuracy)
Proof consistency is poor
Slow output speed
Sampling format can be large or small
Higher system cost Lower
Personnel requirements High requirements No special requirements
Others Need color separation sheet output, printing plate matching
Large floor space
High environmental requirements No special environmental requirements
Initially, proofing was done on the printing press by printing plates (plates and impression cylinders). From a technical point of view, only really outstanding proofs can be called proofing.
Of course, proofing on the press is not profitable. Therefore, people are looking for more favorable proofing methods - printing proofs on roll paper and flat proofers. In order to simulate the results of an actual production press, the proofing conditions must be closer to the actual printing conditions.
Later, people began to use reproducible proofing methods, but these methods can only be a substitute for proofing, because it is no longer printed on the official printed paper with ink, but with pigments and other pigments in the synthetic material. The proofs are printed on the carrier. German called this proofing method "Proof," but in the English vocabulary, the meaning of the word is completely different.
English "Proof" is all proofing methods, German means "color proofing", and color proofing is divided into "colored material proofing" and "non-material color proofing." The corresponding English names are "hard proof" and "soft proofing." "Hard copy proofing" is further divided into "machine proofing" and "offset proofing machine proofing". The corresponding German names are "proof proof" and "proof proof substitute". Analog proofing substitutes are produced by film and digital proofing substitutes are produced by digital data.
In French idioms, there is no professional vocabulary representing proofing substitutes. The more commonly used is its synonym, "Comalin."
In PS, an image size is 103MM*103MM (including bleeding)
