We've decided to print the maps for this year's Ellicottville Adventure Run at a scale of 1:10,000. The maps will be more readable and we'll be able to cover more territory by using two maps. Our hope is to print the maps back to back on one sheet. The date is Saturday August 24, 2019. Register today!
Dave, it may be better to use two sheets back to back. Even with thick paper, printing both sides of a single sheet can have a bit of a bleed-thru effect. And although we all want to save trees, I don't think you'll find much if any price difference for color between printing two sides, or one side of 2 separate sheets. Definitely take a look at one against a strong back-light before you print them all, and then maybe realize that you and competitors won't be as happy with the quality.
Would maps be typically viewed in competition with a strong back light?
Depends if there is bright sun. I've seen 2-sided prints I thought were great under indoor lighting and then been disappointed in outdoors conditions. Maybe back lighting isn't the best explanation, but definitely look at them outdoors in sunlight and shadow conditions.
I regularly print maps on 120 GSM paper or 115 GSM Pretex, and have never had an issue with 'bleed thru effect'
May be entirely different paper, machinery, and map files, but a "map flip" is becoming more common round here. I'm involved in map printing and after initial worries, we don't take any special steps for two-sided printing.
For our recent urban map adventure, we printed the map 2-sided, using HP Bright White Paper (24-pound weight). None of the competitors brought up any issues with map legibility. I just took one of the copies outside, in the bright sun. I could not detect anything from the back side being visible from the front side, unless I held the map up to the sky, which would be an odd way of reading a map. So my sense is that BFLO should have no significant legibility issues printing 2-sided, although I'd suggest using a slightly heavier than normal paper, like what we used. But that also enhances legibility even if printed single-sided.
Thanks for the comments. We use what's referred to as an 80 pound paper. The sheet will be 13 x 19 inches. We'll be sure to do a proper test. I should have also mentioned there will be a 1:5,000 insert map of a "rock city" that's on the map. (Same as last year.)
Legibility aside, an advantage of two sheets is that you can put them side-by-side for route planning.
80 pound should be fine. Good luck!
wow... just to let you know, was sitting on the fence on whether to come this year, but with my vision the way it is now and having to carry a magnifier glass on competitions, this change surely tilts me from the fence to "GO!"
As a potential competitor I would Much prefer single sided. Double would by no means be a deal breaker, but thought I’d throw my vote in.
Hadn't thought of single-sided's advantage for route planning. Thanks @arthurd. Certainly worth serious consideration.
