Piatnik Doppelkopf Franz luminescent marking playing card is an Austrian traditional small paper card. It uses a smaller crowd than Modiano, Fournier and Copag international cards brands. The card’s bright characters and special numbers are easily recognizable. This double-head game with XL design is perfect for those with impaired or limited vision. Maps with a French image are particularly notable for their large corners. These cards can be read up to 5m away. Other marked cards have four corners jumbo index such as Modiano Cristallo and Modiano Peek Index. This is a great advantage.

How do we mark the Piatnik Doppelkopf Card? You can use our invisible ink pen to try this process. You might be able to find an ink that is invisible after marking, if you’re lucky. It wouldn’t work, as professional printers mark cards. Here are three types of infrared contact lens marks. It is easy to read, but also to block, a large mark in the middle cards makes it easy to miss. You can then choose the second type with four corners and mid marks. Even if you have 2 cards, it can still be clearly seen. We don’t recommend the last method, which is tiny marks on the white lines. It is possible to make a mark if you have a special suggestion.
