Earlier this year CRAMBA took on a project to install durable trail marking at River Bends Park using fiberglass marking posts and decals from Rockart. After installation a significant lingering issues was the visibility of the decals for the Single Track: Yellow (Main Trail) sections. The stock Rockart decals (eg: 10-124) are a single color printed over a reflective white base, and even with ordering gold color decals (eg: 10-124-10, a darker yellow) the contrast was so low that the arrow was hard to see.
We considered a few different options including custom decals, hand-tracing the arrows with markers, or re-coloring this loop, but settled on retrofitting the existing decals with cut vinyl outlines. One of our volunteers — Ken Markiewicz — made short work of getting us enough cut vinyl to fix up all the signs in the park, and as seen above it’s radically improves the visibility of the decals.
So that others running into similar decal contrast problems can do the same, I am providing the templates here under the Creative Commons Attribution-ShareAlike 4.0 International license, for all to use: vinylcut_toppers_for_yellowgold.zip
This template contains outlines for both the 10-124 (straight) and 10-125 (diagonal) decals. Outlines are 2.5mm wide with the outer curved square placed evenly over outer colored/white edge and the arrow inset on the white area. We found this provided the best result for keeping the arrow visually separate from the outline.
