We've spoken to the manufacturer regarding the print and received some more detailed information. The print is going to be silkscreened onto the rulers and they are sprayed with an UV protection, to ensure further durability. In their 12 years of operation and manufacturing they haven't had a single case where the print has worn off. After speaking with them we think it is safe to say that the print will be durable!
You’re right, you can’t really measure pixels with a ruler since all screens have a different PPI. So what we did was to simulate 150PPI in order to get a sense of scale that will help you translate those physical sketches onto digital ones. So it’s more about drawing the sketches than measuring devices.
The shipping is based on the cheapest option we've found where tracking for both partners is included. We are not aiming towards making any profit off the shipping, but we try and be realistic since some Kickstarters fail to even deliver because they set the international shipping too low and thus lost money on every sale. So we're doing our best in order to actually deliver every ruler and tracking those rulers are important to us so that you guys don't have to worry about them getting lost.
