pre-press file preparation
The need for pre-press file preparation:
for your work to be seen at it's best on the printed page, each image will
need individual attention during RGB to CMYK conversion. Otherwise,
the image appearance is likely to alter and produce printed results that
disappoint.
Commercial printers, by nature of economics, usually automate the process
and you get less than optimum satisfaction.
PDS on the other hand, take a before-and-after view of all images and adjust
each one to give the best possible printed
result.


Image editing: not
all of our clients have the ability to carry out image editing to the quality
demanded by the chosen reproduction process. To them, the PDS
image editing service has proven it's worth many times.
Whether an image
needs colour correction, sizing, removal or addition of detail, background
alteration, the combining of images, blurring and sharpening, PDS will do
all this if required.
CMYK conversions: to
reproduce photographs in the printed medium requires the images to be in the
CMYK colour space and not RGB. Achieving this is not a matter of pressing
a magic button. If you want the optimum result, careful
conversion is essential.
Factors that need to be taken into consideration include: the press on which
the job will be printed, whether the pre-press process is for 'computer-to-plate',
'film-to-plate', off-set litho, web off-set, digital, and not least of all;
in which country is it being printed?
There's more; dot gain will also
need to be considered - amongst other things, this is a function of the paper
stock, the plate's screen ruling and the ink type. This is by no means
an exhaustive list! Bear in mind, that the print run costs the same using
poorly converted images as it does using correctly prepared ones - and
the difference really does show.
When we convert we also expect to have to adjust various aspects of the images so they print correctly and accomodate the restricted gamut the printing process allows. Additionally, to ensure that we are achieving this, we make full use of our 'Contract' proofer facilities to verify the changes we are making.See: Contract Proofing
