Printing and finishing guidelines
Screen Ruling: For optimun print results
a screen of 133-150 lpi should be used. Finer screens, up to a maximun
of 200 lpi can also give very good results with careful ink density
control. For dark 4 colour images with high ink density, Under Colour
Removal may be required depending on the quality of the visual. This
will also help to reduce print drying time.
Printing Inks: Conventional, positive drying
inks should de used with or without Infra Red drying assistance. UV
inks may also be used. Avoid using overnight / stay fresh / duct stable
inks (this is essential for all Ice colours and other iridescent papers,
where fully-oxidising inks are recommended). Always allow sufficient
drying time. Anti set-off spray is recommended when printing multiple
colours. Use laser-stable inks fpr subsequent laser printing. It is
always advisable to consult your ink supplier about specific proyects
to ensure ink suitability.
Paper Handling: Select a slower press speed
for board printing. Do not allow the delivery stack to become too
large; prints at the bottom will still be wet and less resistant to
marking. Protect paper from environmental humidity and temperature
changes by always using stack covers or strech wrap.
Litho Printing: For optimun results on textured
and embossed papers increase the blanket pressure or use a softer
blanket to achieve consistent ink lay down.
Varnishing: To achieve a gloss varnish,
it is essential to pre-seal the surface. Silk screen matt UV varnish
should be used first, followed by subsequent applications of gloss
UV varnish to achieve the desired effect. Ensure suitable inks are
used prior to varnishing and that the inks are completely dry before
varnish application. Not recommended for papers weights.
Blind Embossing: All finishes can be blind
embossed. For subsequent laser printing, we recommend a shallow emboss
to allow good feeding and to avoid damaging the emboss.
Laser-cutting: While laser-cutting is easy,
some scorching will be apparent around the cut area. Lase-cut papers
are more prone to misfeeds and jams within office printing technologies.
Hot Foil Blocking: All finishes in the range
can be foil blocked. Foil blockers can recommend the best foil for
the image and the paper chosen.
Folding and Creasing: To guarantee good
folding results, prior creasing is recommended. Creases should be
made parallel to the grain of the board. For best results a creasing
rule and matrix system should be used. Foild into the bead for prominent
Screen Printing: All finishes can be successfully
Additional Information for Embossed Papers:
When trying to blind emboss, hot foil block or screen print on the
embossed papers, it is recommended to first plate sink the area which
will be used.
The direction of the grain and the embossing is always parallel to
the long side ("machine direction" = 2nd number indicated
in the stock size of the sheet. Example: 70x100).
