Black Core means a black central layer
Black Core means paper with a black central layer. For your playing cards, it is a first point of comparison between papers. Colour reproduction and feeding also depend on the finish, inks and settings; this specification alone does not guarantee a resemblance to another brand’s card.
What this information can help you compare
With the same finish, it helps identify the black-core references in the catalogue. To choose a sheet, also compare the finish, basis weight, stated thickness, sold format and packs that are actually available.
The matte references currently include a 300 gsm version listed without a retail pack and a 330 gsm version offered in A4. Availability and pack details remain those displayed by the shop when you visit.
What Black Core does not prove
A black core is not a test of opacity, stiffness, cutting, drying or double-sided printing. These outcomes depend on the complete medium, file, inks, feed and settings. Keep a test sheet and record the equipment used if you want to reproduce the result.
