- A printable matte finish on both faces.
- Black core and paper weight describe different properties.
- Choose the media for the paper path you can use.
What a matte finish changes
A matte surface diffuses light and limits strong reflections. It is a practical option for reading text under a lamp, but blacks and solid areas also depend on the image, ink and driver.
The front and back are printable. Black Core means the black middle layer; the name does not promise equivalence with an official card or identical shuffling behaviour.
Compare the two products
The 300 and 330 gsm products share a matte finish. Weight measures mass per area; use the thicknesses on current product specifications to compare what will pass between the rollers.
Choosing the heaviest paper is not always useful. If the printer documents weight and thickness limits, observe both when available. Missing information remains an uncertainty.
Make a comparable test
To compare the papers, keep the same sheet artwork, driver and lighting. Check feeding first, then printed detail, the back and cutting. This helps you choose for your use rather than the weight number alone.
- Check the manual and the path intended for thick media.
- Print one sheet of each product without changing several settings at once.
- Let them dry and compare in the same sleeves if you use them.

Questions about this guide
Is 330 gsm always better?
No. Printer feeding, the thickness you want and intended use matter more than a higher weight alone.
Does Black Core mean matte?
No. The core is in the middle and the finish is on the surface. Luster also has a black core with a satin surface.
