Foil Blocking

Certain products have an option to add a gold or silver foiled shape onto areas of your design.

How to supply us your areas to be foiled

All of our InDesign templates include specific colour swatches for all finishing options. Simply supply us your foiled shapes filled in spot colour 'OPULEAF-GOLD' or 'OPULEAF-SILVER'   on page 3 of your PDF.

OR the instructions below detail how to set up the colour yourself:

1. Create a New Colour Swatch
2. Name the swatch 'OPULEAF-GOLD' for gold and 'OPULEAF-SILVER' for silver  (must be exact)
3. Set Colour Type to Spot
4. Set Colour Mode to CMYK
5. Colour Make-up of OPULEAF-GOLD is 0% Cyan, 40% Magenta, 93% Yellow and 0% Black (must be exact)
     Colour Make-up of OPULEAF-SILVER is 14% Cyan, 9% Magenta, 0% Yellow and 0% Black (must be exact)
6. Set swatch to Overprint (Window > Output > Attributes)

Design with a little tolerance for mis-registration

Foil stamping or blocking is a process where a solid area of the paper has a silver or gold metallic foil applied by heat and pressure This means that the registration with print can vary by ±1 mm. This means you should expect the Foiled element to move around the page by up to ±1mm.

Don't try to align fine detail

Foiling is not suited to alignment with fine detail, such as small type, or shapes with thin lines.

Our rule of thumb:

  1. avoid positive lines thinner than 0.5mm, and
  2. avoid reversed-out lines thinner than 2 mm.

You’ll get best results when you don’t try to match the Foiling to printed objects, and instead treat it as a design element in its own right Seperate Foiled elements should have a minimum spacing of 1mm. Placing elements too close to each other will result in them becoming one shape and filling in.

Avoid using Foiling on small text. Fine fonts, particularly those with Serifs or tapered lines do not produce good results. The thinnest part of the font must be 1mm in width.

Avoid large Foiled areas over the page edge

Avoid having areas of Foiling bleeding to the edge as chipping and flaking of the Foiling area may occur once the job has been guillotined.

Vectors only for Foil Blocking

Foil Blocked elements must be supplied in vector format; any text shapes to be spot-varnished must be converted to paths/outlines.

Solid Foiling only; no tints

Foiling cannot be specified as a gradient or tint, i.e. a changing tint from 100% to 0% over an area of artwork.

Foiling Imprint

The process of foiling leaves a faint cross hatch effect on the reverse of the product where foiling is applied on the front. Foil residue can also be present on the edges of foiled areas. This is inherent in the foiling process.
