All Colour images should be colour separated using the correct
icc profile.
General Points to observe.
Advertisements must be supplied in PDF format.
Please ensure the Acrobat distiller settings
are as follows:- PDFX-1a (2001) Compatibility Acrobat 4 (PDF
1.3) This is a standard option in most major design
applications and helps ensure problem-free output.
The PDF must be made to the exact size of the
advert space booked.
DO NOT include White Space, Registration
Marks, Colour Bars or other furniture.
Colour Images should be in the CMYK colour
space (NOT RGB, Indexed colour, Patterned or Lab colour space)
Monochrome (Black & White) Adverts should
be Greyscale and NOT RGB or any other Colour space.
The maximum ink weight on all newsprint
products is 240%.
The minimum ink weight visible on magazine
products is 5% per colour channel.
4-colour type should not be used smaller than
10 point.
Tinted single-colour type should not be
smaller than 8 point.
Single colour solid type no smaller than 6
point.
White out of colour type no smaller than 10
point.
4-colour lines no finer than 1.5 point.
Single colour tinted lines no finer than 1
point.
Single colour solid line no finer than 1
point.
White line out of colour, no finer than 1.5
point.
Be aware of your overprint settings.
White text set to overprint will NOT appear,
(even if it does Look correct on screen and prints out on your
laser printer) Yellow text set to overprint a Magenta panel will be
RED, therefore Knockout settings should be used if Yellow text is
the result expected in print.
View your PDF in Acrobat Professional and use
the Overprint Preview to check.
Spot Colours and Pantone colours MUST NOT be
used anywhere in the document, you must convert all these colours
to Process.
View your PDF in Adobe Acrobat and use the
menu Separation Preview to check.
If there are any channels, other than C,M,Y
or K it will need to be corrected before uploading.
All Spot Colour Advertisements should be
separated SPOT AS PROCESS i.e. for a Spot Red Advert there should
be a Black channel separation, the Magenta and Yellow separations
should be IDENTICAL, and the Cyan channel should be empty (Blank)
Outline any font that does not embedding.
Ensure only 1 page is in the PDF (i.e. No
Multi-Page Documents) RESOLUTION The Newspapers are printed with a
final screen ruling of 100 lines per inch. Therefore the absolute
minimum resolution for scanning Photographs, both Colour and
Monochrome, is 150 Lines per inch, at the final size of the
image.
Most experienced repro suppliers keep to a
standard 304 lines per inch, which serves their magazine quality
output if ever they need to re-purpose the original RGB scan.
Line art scans should be at least 600dpi for
Logos etc. and 1200dpi when scanning pre-screened artwork.
Dot gain
If you have installed, and are using the .icc profile correctly,
Dot Gain will be compensated for within Photoshop when you convert
and view your image.
TAC
If you have installed, and are using the .icc profile correctly,
GCR and TAC will be set within Photoshop when you convert and view
your image.
For information the TAC should not be more than 240%.
With Coldset Offset litho printing, NO heat or other drying
assistance is used therefore, ink levels above the recommended 240%
will result in set off and other press related problems. The
Printsure Preflight check will reject all files over the specified
limit.
Tonal correction
Workstation Monitors must be calibrated to obtain the best
results.
The best way to adjust images is to scan at the required
resolution in RGB mode, with a calibrated device that embeds an icc
profile. This scan when opened in Photoshop will enable full use of
colour management when opening the image.
Magazine file creation
Guidelines for reproduction and supply of digital
material for gravure magazines
Please note that failure to follow these guidelines may lead to
reproduction errors.
Our production process is built up in a 4-colour CMYK mode. Thus
all colour and tone staging are matched to the print colours in the
supplied digital data. A corresponding print result, within the
tolerance customary to the industry, can only be attained if these
preconditions are fulfilled.
The advertiser is responsible for the correct composition of the
digital material.
Image Structure
General:
The reproduction colour space is CMYK,
whereby the colours are processed in CMY and K is used only for
key, modulation and contrast. (Data defined in RGB/Lab is not
processed)
Do no apply spot colours.
Please avoid a strong UCR and GCR
construction as this can lead to a unexpected print
results
Exceptions:
Images with fine patterns can result in moiré
for instance with herringbone and glencheck patterns.
Black types used in images for instance on
packaging should also be avoided. Please make this in thin colour
line work with an over proportional black overprint.
Delicate structures / images with fine
structures, as well as too high a sharpness of detail, can also
result in moiré. Often this is not noticeable in proofs.
The maximum dot area is 340%. This is why we
recommend to use 360% in the separation profile. We have put
similar profiles at your disposal.
The first shade to be visible is 5% per
colour channel.
Technical shades and fonts should be defined
with at least 7% per colour channel.
Over/underfilling:
Dark colours should be made with an overfill
of 0.06 mm.
White out letters on dark backgrounds (4c)
should be defined wider in the sub-colours.
Black frames are to be defined with 0.06 mm
overlap.
Texts
Black text must be defined so that it
overprints 100%.
At pure black changes (text versions) there
must be no colour constituents in the line work. I.e. coloured
text, logos and background colours are to be incorporated into the
CT.
The selection of the type and size of the
text font must be adapted to the gravure printing process, taking
the print fit into account.
0.2 mm for lines in single and multiple
colour
For white out texts we recommend to keep at
least 0.25 mm line width.
Extremely thin type faces and serifs can
result in a bad presentation of the texts in the print.
