The prepress proof gives an approximation of
what the final image will look like, this is
especially important in four-color printing. This is
your last chance to catch prepress errors. Bluelines,
color keys, "Rainbows," ink-jet, and laminated
four-color proofs are examples of prepress proofs.
- Review the proof
counting page numbers. Make sure that pages back
up to each other.
- Check borders
and rules for alignment and crossovers.
- Reexamine
headlines and other display type for typos and
placement.
- Study areas
which may have critical register.
- Look carefully
at each page to be sure no elements have been
mistakenly masked out or trimmed off.
- Check every
photo to be sure it is positioned, scaled and
cropped correctly.
- Clearly circle
every blemish, flaw, broken letter and anything
else that seems wrong.
- Are all
corrections made from previous proofs?
- When proofing
multicolor jobs, know what copy prints in each
color. Are color breaks clearly indicated?
- When reviewing
process color proofs, are the proofs being
reviewed under the same lighting conditions?
(Industry standard is 5000 K.)
- Are neutral
colors in proper balance? Look at whites, grays
and blacks (gray balance). If they show a
significant color cast, the color is probably
out of balance.
- How is the
overall reproduction of color? Focus on "memory"
colors such as blue skies, green grass and red
tomatoes - they are the toughest to match. How
does the rest of the color look?
- If spot varnish
or coating is being applied, is it indicated?
- Are screen
percentages correctly indicated?
- Are the margins
consistent?
- Have you
confirmed: Paper stock? Quantity? Type of
binding?
- Are place, date
and time, contact name and phone number included
in delivery instructions?
- Is the job
trimmed to the correct size and properly folded?
- Are all perfs,
scores, glue spots, etc., correctly indicated?
- Any last minute
corrections to the copy?
