Set Your Files Up Correctly For A Perfect Finish

Creating amazing metallic foil print means making sure your finished artwork is high quality and correctly set up. In this blog, we'll try to explain the best way to set up your artwork and suggest things that you'll need to check and avoid so the flow from purchase to print is streamlined.

To make this blog easier to understand you can download the example foiling file PDF which we've used throughout the content. This should make following along simple.

The FInished Product

Don't worry, the tips are coming, but here's a finished photo of the example we'll be using. Take note that in this example we're using colour print and foil together to create some lovely highlights but still keep the flyer readable.

Understanding the basics  

Understanding The Basics

The first thing to grasp is that the foil is printed separately to everything else. It is the final step in the printing process as the foil layer always sits on top of everything else. So in the example above, which is single sided, the colour print in the middle will be laid onto the paper first, and then that print will be sealed off with a laminate (foil sticks to bare toner so we need to cover up the bits that don't want to be foiled). The next step is the precursor to foil which involves printing everything for foiling in 100% black which you can see on the left (0% Cyan, 0% Magenta, 0% Yellow, 100% Black). Once we print this layer, it's time to run it through the foil laminator which heats both the black toner and foil to over 100°C and fuses it with pressurised rollers.

Movement in our printer  

Movement In Our Printer

No matter the machine or process used for foiling, from us or anyone else, there will always be a movement for where the metallic foil can land. Micro-movement is an attribute that is unavoidable and should be taken into consideration when designing your artwork. Our tolerance is 1.5mm out in any direction. The cause is due to the paper moving around in our printers. For most peoples artwork this won't be an issue, and you'd find it hard to notice, but on some very intricate designs, it can mean we have to come back to you and suggest some tweaks to make it printable. You can see our example above which illustrates two scenarios of the foil landing 1.5mm out in different directions.

Splitting Your Artwork

Creating separate artboards is crucial for foil printing, it creates clear instructions for what is to be foiled and what is for print. We call these the foil layer and print layer. If you only have a single-sided print, you can expect to have one of each. If your print is double-sided, then we'd usually expect four artboards which consist of the front foil layer, front print layer, back foil layer and back print layer. If you're having double-sided print but only have one side foiled, then you should omit the foil layer from the side you're not having foil printed to.

We Always Print In CMYK

One common mistake we often come across is that people sometimes supply their artwork in RGB. It is impossible to print in the RGB format, and it's worth noting that when converting to CMYK, some RGB colours look different. That's why when you first start designing your artwork it's always best to start and finish in CMYK for consistency sake. We can convert it on our end but can't guarantee the colours will be 100% the same tone.

Foil Print & Pantones

Similar to RGB, we also can't print Pantone colours you've chosen off your computer monitor. This is because all monitors are calibrated differently. If you happen to have a Pantone booklet and pick a colour from there. We can create a CMYK makeup that will be very close to it, but not 100%. One thing to keep in mind is when we laminate for foiling, the layer can darken the shade of your print, so you could say this defeats the point of using a Pantone colour, to begin with. A good rule of thumb is to supply your artwork a little brighter than you want it.

Other Settings For Your Foil Artwork

Although the most important step to foiled artwork is splitting out your layers, there are still some other guidelines we need to make you aware of:

2mm of bleed
300 DPI
Vector (will also take bitmap however this can produce jagged edges on foil)
Supplied as PDF, embedded AI, EPS, TIF or JPG
