The brightness of the metal blends with the iridescent
reflections, creating a new paper dimension.
Innovative, technological, creative, avant-garde, provocative, sophisticated,
mysterious; Witcel Metal Color, papers with surface of light-changing
color, that allows to create differentiated printed communications.
This line uses state-of-the-art technology in paper manufacturing to
create brightness and luminosity on both sides of the paper thus achieving
impressive results of depth and dynamism, as well as character and innovative
Applications: annual reports, catalogues,
covers, invitations, packaging, menus, cards and envelopes.
WITCEL METAL COLOR AND THE ENVIRONMENT
Concern for the environment is one of our major priorities:
- We use only Elemental Chlorine Free (ECF) pulps.
- Pulp is sourced only from commercially managed forests.
- All mills are accredited with the International Environmental Management Standard.
- Investment in reduced water used and effuent volume processes. All effluent
plant residue is put to product re-use thus eliminating the need for landfill
Printing and finishing guidelines
Due to the optical effect of these papers, the printed result will
differ from other papers.
Print techniques: Witcel Metal Color papers
are suitable for widely used print techniques, such as: offset, letterpress,
embossing, hot stamping, blind embossing and silkscreen. A pre-test
is recommended for thermography.
Important: The characteristic metallic effect
of these papers will show through the printing and may reduce the
image contrast. As a result, the dark areas can be difficult to achieve.
This is not a paper defect, but one of its characteristics. It is
normal for some particles of the paper's special surface to transfer
to the blanket. Therefore, it is recommended to clean the blankets
after 3,000/4,000 impressions.
Inks: We recommend using fully oxidising
inks. Semi-fresh inks can be used. Consult your ink supplier for specific
colors or formulations. Witcel Metal Color do not contain ground metals
and are not foil papers.
Screen ruling: For best results, screen
rulings of 150 lpi are recommended. Under colour removal (UCR) may
be required on jobs with large dark areas.
UV varnishes: Silkscreen UV varnishing is
the only method to achieve a good gloss finish on this absorbent paper.
Ensure sheet is pre-sealed with acrylic sealer. A matt UV varnish
must be laid down prior to gloss UV varnishing. Repeat varnishings
may be required. We do not recommend other machine varnish applications.
UV varnish is not recommended for further laser printing.
Sealing/fixing varnishes: Sealers can be
used to avoid marking during further processing and handling, although
the paper's metallic nature will be compromised. Sealing is not recommended
for further laser printing.
Laminating: The paper accepts laminates
easily, although some "silvering" may occur. Increase laminating
pressure and apply excess adhesive to help reduce silvering. Laminates
will reduce or negate the metallic effect.
Folding and creasing: To guarantee good
folding results, prior creasing is recommended for paper weights over
120g. Creases should be made parallel to the grain direction. A creasing
rule and matrix system should also be used. Always fold towards the
opposite side of the creasing.
Binding and glueing: The use of hot melt
or acrylic adhesives is recommended. When using spiral binding, be
sure that the blades are sharp. Hole punchers work better. Witcel
Metal Color can be sewn through the center, partially or completely.
