What does Metal FX colour mean?

Metal FX®: For ultimate effects! Metal FX® is a process which allows any number of metallic colours to be incorporated into a conventional CMYK (Cyan, Magenta, Yellow, Black) print job. An ultra opaque fast drying silver is applied in various tints in the areas to be metallisized and tints of CMYK inks are applied on top to produce the metallics. The eye-catching effects that can be achieved are possible without the excessive extra cost normally associated with process plus spot colour print. NB. The Metal FX® process is most effective on Gloss Art Paper. Whilst good results can also be achieved on Silk Art (Business Cards) or Matt Art (Handouts) the results are less predictable. There are currently no economical ways of proofing Metal FX®. We would always recommend a small print run to ‘prove’ the artwork before a large Metal FX® job is printed.
