Paper and Card Stock

The whole printing process begins with paper. Paper comes in a variety of weights and finishes, and every printing company offers different options depending on their paper suppliers and presses. You’ll find the widest variety of paper options when working with offset printers because operators are able to calibrate the press based on thickness and coatings. On the other hand, digital printers used for print-on-demand have a limited amount of paper options.

Parent Sheet Size

Parent sheets are large pre-cut pieces of paper, typically designed to fit 4–16 pages of a project on each side or 55 poker cards. They come in many weights and are often pre-coated with gloss or matte.

One of the major factors in the cost of a printing project is how many parent sheets will be used, which is why certain standard sizes (8.5″ x 11″, 6″ x 9″, 9″ x 12″) and page counts (multiples of 16) are usually the most cost-effective choices since they can maximize the parent sheets used.

Paper Weight

Paper weight refers to a particular thickness of paper stock. There are many different weight classifications, including text, cover, index, bond, bristol, and more, as well as the metric system classification of grams per square meter. When comparing within a specific classification of paper, a lighter weight indicates a thinner paper.

Text

Text is a classification of paper most commonly used for the interiors of books. Text stocks are usually measured in pounds (noted lb. or #).

Cover

Cover is a thicker classification of paper most commonly used for book covers, measured in points (noted pt.) and sometimes in pounds (noted lb.).

GSM

GSM (grams per square meter) is the metric system's universal measure for paper weight and can be converted into lb. and pt. For example, 80 gsm is 55 lb. text and 350 gsm is 14 pt. cover. Typically used to describe card paper.

Make sure to include both weight and classification when comparing paper stocks, especially when comparing quotes from different countries. For example, many US printers may give you a quote for “80 lb. cover” which is much heavier than “80 lb. text”. If you’re not sure where to begin, you can always use our industry standards pages to help with your decision.

Cardstock

The GSM (grams per square meter) measurement mentioned in the paper weight section above often applies to playing card stock. The higher the number (300 gsm, 310 gsm, 330 gsm, 350 gsm), the thicker the cardstock. When selecting a paper weight for your playing cards you need to also consider the core, the material placed between the two pieces of paper that make up your card (e.g., 300 gsm Blue Core, 330 gsm Black Core).

What Does a Card Core Do?

The job of the core is to make your card less transparent and more durable. From lowest quality to highest, the cores range from: coreless, grey, white, blue, and black. Many card printers use different terms to explain the cores, so be wary of the name and request a sample when possible. You can determine a cards core by ripping the card in half — the core color should be visible.

Selecting a Card Core

Most often board game creators will select a coreless cardstock since their cards will not be handled frequently. On the other hand, our card game creators lean towards blue and black core since their games revolve around cards, which are typically held in players’ hands the entire game.

Paper Coating

Coating is applied during the paper manufacturing process. Coating affects the way that inks are absorbed by the paper, making halftone dots and text stay sharp. Any paper weight can have a coating, and which coating to choose is largely a creative decision. Here are the three most popular options:

Gloss

Gloss coating gives a deliberate shine that causes colors to pop. This coating is very reflective.

Matte

Matte coating, sometimes also referred to as semi-gloss or dull, provides a more subtle shine. There is less light reflection than with gloss, and the reflection is more diffused.

Uncoated

As the name implies, no coating is applied to uncoated paper. Uncoated paper is rough to the touch and perfect for projects that need to be written on, such as workbooks. However, it also has less protection from everyday dirt compared to coated paper.
