Designing for Foil
The left-hand card in this photograph is the non-foil version, while the right-hand side is the exact same artwork printed on holographic foil.
This is not the “wrong” way to do it, as this subtle effect might be desired. If you want a more pronounced holographic effect, though, there are some changes you can make to your artwork to get the most out of our holographic foil.
The key to making the foil stand out is to create a lot of contrast between background and foreground, and a lot of contrast with your text and graphics. Keep in mind that dark colors will only be slightly holographic, light colors will show a lot of the holographic effect, and white will be fully holographic.
To make a special foil edition of this card in particular, a few tweaks were made. The most obvious is that the dark background is changed to completely white so the holographic foil will be at its brightest instead of muted by dark colors.
The smaller changes focus on creating contrast between the foil and the important graphic elements. The icons on the bottom half of the page have a white border that would cause them to get lost in the white background, so a black border was added around them. The saluting figure was changed to blue for the same reason. The card icon in the upper right-hand corner now has a black outline, as the white outline was indiscernible from the light-gray fill color when printed on foil. The transparent fill color behind the text was made considerably more opaque to bring out the white text.
Before and after optimizing the image for holographic foil
The holographic result of the changes to the card design. The tweaked design is printed on non-foiled paper on the left-hand side and foil on the right-hand side for comparison’s sake.
Now when the card is printed on foil, the holographic effect jumps out immediately while all important elements of the card are still easy to read.
The areas of your artwork where you want to really show off the holographic effect can be more than just a field of white. You can add faint patterns to areas of foil to change the appearance of the foil without diminishing the sheen by much. A light gray hexagon pattern in the background drastically changes the presentation of this card.
Adding a faint pattern can produce interesting effects on the holographic foil.
The main drawback to this printing process is the silver iridescent foil becomes the brightest color achievable, meaning you will not get bright whites anywhere. All colors will appear slightly darker than if they were printed on brilliant white paper. You can simulate the effect this will have on your artwork during the process of creating your game, or you can use the holographic patterns provided below (or on the product page). Import the appropriate foil pattern file into your art program, make sure it is on top of all the other layers, and set the blend mode of the imported file’s layer to Multiply.
