Blank A4 cardstock for card printing

Held in the EU.Printed by you.

Black core and foil sheets, delivered across the EU. No customs form, nothing extra to pay at your door, no three-week wait.

Rainbow Holo

A4 · 210 × 297 mm

Rendered preview. Move or drag across the sheet to move the light.

01 / The core

Light stops in the middle.

A coloured layer runs through the centre of every sheet. Hold a printed card up to a lamp and the back does not show through the front.

About 0.35 mm, against about 0.32 mm for a standard card. That 0.03 mm is thinner than a human hair, so even a 100-card double-sleeved deck is virtually indistinguishable.

02 / Finishes

Ten finishes. Every spec we have, stated.

Every figure has a source.

05 / The guide

Cardstock for printing your own card designs.

Blank A4 sheets for printing your own card designs at home. Every sheet is blank, so the artwork is yours.

What core cardstock is

Core cardstock has an opaque layer through the middle of the sheet. It stops light coming through, so the back of a printed card does not ghost through the front when you hold it up to a lamp.

Holographic and foil cardstock

Foil cardstock carries a holographic film on the face of the sheet, so a printed card catches the light. The finishes run from rainbow holo and surge foil to twill, halo, fractured, facet, galaxy and gold mirror.

Inkjet printing on thick sheets

Check the printable side of each stock first. Black Core prints on both sides, and Rainbow Holo is for printing on its matte side. Thick sheets feed best one at a time through a straight or rear paper path.

How many cards fit on an A4 sheet

An A4 sheet gives nine cards at card size 63 × 88 mm, three across and three down. A 60-card deck takes seven sheets. Work out your paper cost.

Card printing paper in Europe

We deliver across the EU, so there is no customs form and nothing extra to pay at your door.

06 / Questions

Before you order.

Will it feed through my printer?

These are thick sheets. Use a printer with a straight or rear feed path rated for heavy media, one sheet at a time. Check your printer's maximum media thickness against the spec of the stock you pick. Tested on an Epson ET-8550. We are not affiliated with Epson. For more, message us and we will help you out.

Which sides can I print on?

Each stock lists it. Black core prints on both sides. Rainbow holo is foil on one side and matte on the other; we only promise the matte side for inkjet.

Are the moving sheets photos?

No. They are rendered previews that show how each finish catches light. Some finishes also have a Photo view with pictures of the real sheet.

Where do you ship?

Across the EU. Orders are usually dispatched within 24h of purchase, and shipping depends on the shipping line you choose. Postage is calculated at checkout by weight and zone.

Can I return it?

Yes. You will have 14 days from delivery to withdraw. Full terms go up when orders open.

How many cards can I print on an A4 sheet?

Nine cards at card size 63 × 88 mm, three across and three down.

Is the cardstock blank?

Yes. Every sheet is blank, and the artwork you print is your own.
