Picking up from the first post where I had figured out a way to marry the functional purpose of the board with a space scene background illustration and was beginning to develop the illustration and game layout to be as if the board is a screen from within the players space ships. To bring about the feeling of a screen I made up the board layout in Illustrator. I created some simplified iconography for the various positions and used the lovely Economica fontface.
I purchased some sheets of 3mm acrylic from Kings Plastics and after some adjustment of the illustrator file to set it up appropriately I laser etched the design onto the plastic.
The laser cutter cuts or engraves a 0.25pt line to a set depth, so set all strokes to 0.25pt and differentiate between cut and engraved lines with colour. All text needs to be made into outlines. There are lots of resources for setting up your files on the fabrication workshop info page. The fuzzy look to the plastic while in the laser cutter is working is because I coated the acrylic in a thin film of washing up liquid which dissipates the heat and prevents any discolouration or cloudy spots from over heating the plastic.
Here you can see the acrylic placed over the a print from the etching.
After scanning and digitally touching up the etching and layering in some further illustrative elements I printed it onto acetate and screen printed the illustration onto the reverse of the plastic using water based inks. Screen printing is a well documented process but some notes on printing onto plastic;
Firstly it would have been much better to have used a larger screen as the edges of the print were susceptible to errors from the over stretching of the mesh where the squeegee approached the frame. It was essential to build a supportive frame of the same depth as the acrylic around the sheet before printing to prevent the squeegee catching on the edges as I drew it across. I attempted to print with some fluorescent acrylic which unfortunately due to the thin layer of paint applied during screen printing came out very pale.
I added a sheet of iridescent window films both to protect the print from scratching and to shine through all the blank areas in the illustration. Ultimately however I wasn’t happy with the quality of the screen print. The gradation between black and transparent lost all detail when compared against the digital file and looked flat.
The lovely Jon McNaught Suggested a method of… (going to make a separate post because this was a really interesting tip)
I experimented with digital printing onto acetate and various methods of mounting the acetate to the acrylic but since the fixative sits between the design and the acrylic even the finest misting of fixative shows as a grainy texture dulling the richness of the black.
Next I had the design printed onto vinyl window sticker by the high quality art printers Hello Blue. While the printed vinyl surface was a little fuzzier than the acetate the print quality is a lot richer than the screen print and after much practice learning to apply window film, perfectly aligned and without even the smallest of air bubbles I got the two layers of film onto the board.
While there is still some tweaking to perfect the quality of the physical artefact I feel like the illustration and end product are starting to shape up into a beautiful artefact which hopefully will draw players into the game world.
