Card Stock Explained: Black Core, Blue Core and Art Paper

Key takeaways

  • Black core blocks show-through and gives the firm snap most playing cards and TCGs are judged by.
  • Blue core is slightly softer in the hand and common in board game decks where handling is gentler.
  • Art paper is the economical option — but the laminate, not the paper alone, decides how long the deck lasts.

Card stock decides how a deck feels in the hand, how it shuffles, and how much it costs to produce. Three stocks cover most custom card projects.

Black core: the standard for playing cards and TCG

Black core board is built from layers with a black glue core that blocks light completely. At 300–350gsm it gives the snap players expect, hides artwork on the reverse side, and holds up to repeated shuffling. It is the default for playing cards, trading cards and card games.

Blue core: softer feel, slightly lower cost

Blue core uses a blue-tinted core. It is marginally softer and usually less expensive than black core, and it remains a good choice for promotional decks, flash cards and game prototypes where the premium snap is less critical.

Art paper: for tarot, oracle and booklet-style cards

Art paper (300–350gsm) is a solid board without a glued core. It takes rich, saturated print and works well for tarot and oracle decks, affirmation cards and learning cards where a softer, more paper-like feel is preferred. It is not ideal for heavy shuffling.

Which weight should you choose?

  • Playing cards and TCG: 310–350gsm black core
  • Game cards with many components: 300–330gsm blue core
  • Tarot and oracle decks: 300–350gsm art paper, matte or soft-touch laminate
  • Flash cards: 300gsm art paper with matte lamination for writability and durability

We recommend confirming stock with a physical sample: the same 350gsm can feel very different with a matte, linen or soft-touch surface. Samples take 5–7 days after specifications are confirmed.
