The digital
desktop shifts the responsibility of preparing artwork for reproduction
to the designer. Identify an area of file preparation you need to learn more
about and provide an overview (200 word max) of the process and its
significance.
Printer’s Marks
and Bleed Areas
I find that I am still lacking in the
terminology of printing and why I should get into the habit of using printer’s
marks and bleed areas. They help the printer to line up and make sure that the
print is running properly and make sure that mistakes are kept to a minimum.
They determine where to trim the paper after printing, align separation films
when producing proofs, measure film for correct calibration and dot density,
and allow colour consistency within a print run.
Printer’s marks including -
- Crop marks that add cross hairs in each corner
that determine where the page is to trim it.
- Bleed marks add lines that define the
amount of extra space outside the page size that show how far you should extend
your artwork of the page.
- Registration marks add small targets
outside the page area that the printer can align different separations to in a
colour document
- Colour bars add small squares of colour
representing CMYK tints and grey tints that the printer follows for colour
consistency
These marks are used for all manner of
different areas of printing, from the beginning, making sure your print is
lined up correctly through to colour consistency and the finishing of the job,
aligning and trimming.
