Hi damois !
I will try to bring my little knowledges if it helps
1. As far as I know, there is no perfect paper in stores to be able to print in both sides, without having the ink to pass through it :/
If you want to print many booklets, you should try heading to a professionnal printer and show him the result you want, and what his price would be.
2. The website aleary gives you the ability to download a zip file containing oredered pages ready to print. Select the "Download for printing purpose" button.
3. Woops, maybe I have merged topics too fast. I don't understand what Spiral booklet is talking about. But if the booklet is named as a custom, then it is an original creation. If it is named by a world region, event restored it remains the same as the scanned one.
4. +1, don't see the point
5. You have 2 options to achieve that. First, you have enough money to buy you something like that (sorry I don't know how this is called in english) :
Or, you can use and empty pen, or something else hard and edge rounded, and then press it along to a rule to get the mark. But be carefull not to cut the box, and use a paper between the box and the pen to avoid scratching the ink.
6. You have also many options here:
- Use a 330g/m² inkjet photo paper
- Enhance the result with a protective transparent sticker (used for children school books for instance).
- Use a printable sticker and buy a thick paper to glue the sticker to it.
- Go to a professionnal printer and ask him for papers and price. We found some professionnal printers here in Frane with the same king of paper as guenuine boxes, and for a price less than 2 Euros per box !
Gook luck, and enjoy making your boxes.
