Proofing > Digital Proofs vs. Wet Proofs
Digital Proofs vs. Wet Proofs:
Advantages of Digital Proofs
- The cost to output digital proofs is more competitive compared with wet proofs if only one set of proofs is required.
- Preparing digital proofs are faster than preparing wet proofs.
- There are fewer problems with dirt, spots, or registration problems which are common in wet proofing.
- Translating Digital proofs to Printed sheets: digital proofs are warmer than wet proofs because of the nature of chemical ink--it is different from actual printing ink. The color tolerance between digital proofs against the press sheet is about 10% to 15%.
- Digital proofs are the fastest to output (it takes about thirty minutes to output eight pages of an A4 size).
Disadvantages of Digital Proofs
- Digital proofs do not reveal problems in the files, such as trapping, overprints, or moirés.
- The tint colors in digital proofs cannot be matched during actual printing.
- PMS colors are not accurate in digital proofing as it is in wet proofing.
- Digital proofs are not suitable for black and white images, duotone, or 4-color black and white images.
- Lineart or rules will be thicker than actual size due to distortion.
- Digital proofs are printed on digital paper so the color will be slightly different because is not on the "actual" paper.
Advantages of Wet proofs from CTP Plates
- The cost to output wet proofs is more economical if several sets of proofs are needed.
- The color is more accurate for black and white, duotone, and 4-color black and white images or for PMS colors.
- Problems in the files will be apparent, such as trapping, overprints, and or moirés.
- Wet proofs use the same paper type and weight as it will be used during manufacturing.
Disadvantages of Wet proofs from CTP Plates
- Wet proofs take longer to prepare than digital proofs.
- Dirt, spots, and registration problems cannot be avoided.
- The cost of outputting wet proofs is high if only one or two sets of proofs are needed.
