With multicoloured foil, you can turn a wide range of CMYK colours, into multicoloured foils. Our multicoloured foil uses a special processed foil system that is applied under the four colour printing process to create an array of foil colours. It’s simple, affordable, and makes your prints stand out from the crowd.
For a multicoloured foil job, you must include a multicoloured foil/mask file along with your CMYK file. The mask file indicates where the foil will be placed. The file process is the same as spot UV—100% black where foil is placed, 0% where the foil is not placed.
Normal CMYK file
Multicoloured Foil Mask File
Use 100% black to indicate where you would like the Multicoloured Foil.
White will indicate no Foil.
Here are some more things to keep in mind when creating your multicoloured foil artwork:
Make sure the mask and CMYK print file are aligned and match up properly.
Multicoloured foil works best on lighter colours. The darker the CMYK colour, the less the multicoloured foil look.
Do not use very thin or small text and artwork with multicoloured foil. Use san serif fonts above 12 point for best results.
If you would like only silver foil to print in select areas, make sure to have at least 15% black in the selected area on the CMYK file. White in the CMYK file that is 100% black in the multicoloured foil mask will still appear as plain silver. However, for a higher quality plain silver foil, we recommend to have at least 15% black in your selected area on the CMYK file.
When creating knockouts in the multicoloured foil mask or in the CMYK print file, beware there might be a “Halo” of white around the knockout area. To prevent this, grow/stroke the multicoloured foil area in the mask by 1–2 pixels. This will allow the multicoloured foil to bleed into the CMYK area, reducing the white “Halo” effect. You can also fill in the knockout with a color to reduce the effect further.
