What is Cardstock?
Cardstock, also known as cover stock, is a heavy-weight paper material made from wood pulp. It is designed to be rigid enough to hold shape for packaging and invitations, while still bending slightly for folds and assembled inserts. Cardstock is measured in terms of weight (pounds or GSM) and thickness (points or mils), which determine its durability and suitability for specific uses.
Properties of Cardstock
Cardstock has various properties, including high durability, smooth surface texture, and a range of thicknesses (10pt–32pt) and weights (60–120 lbs), making it versatile for printing, packaging, and creative projects.
- Durability: Cardstock is highly durable, ensuring longevity and reliability in applications such as packaging and greeting cards.
- Thickness: Measured in points (pt), with1 pt is commonly treated as 0.001 inches. Common thicknesses range from 10pt to 32pt.
- Weight: Typically ranges from 60 lbs to 120 lbs (147 GSM to 640 GSM), with 80 lbs being standard for most applications.
- Surface Smoothness: It offers a smooth texture that enhances print quality and design integrity.
- Versatility: Suitable for diverse applications, including packaging, branding, and professional printing.
Types of Cardstock
Common cardstock types for packaging are uncoated (for writeability and matte graphics), coated (for brighter color and smooth printing), solid bleached (for clean white appearance), colored-core (for distinctive edges after die-cutting), and recycled (for lower-form waste claims).
- Coated cardstock for sharp graphics and smooth color blocks, if the artwork uses halftones, small type, and fine line work.
- Uncoated cardstock for softer ink spread and a more absorbent surface, if your brand uses matte looks with legible text and controlled dot gain.
- Dyed-colored cardstock where the sheet color shows through at edges, if packaging is cut or die-shaped and edge visibility matters.
- Specialty textured cardstock for visible surface patterns and tactile differentiation, if your design uses spot effects and requires consistent texture under viewing.
Print and Finish Driven Distinctions
Surface finish changes ink behavior and the results of downstream coating. Coated grades reduce visible paper grain and support higher contrast, while uncoated grades increase ink absorption and can shift perceived shade under matte finishes.
- Matte-coated cardstock for reduced glare, if the package sits in retail lighting where reflections reduce readability.
- Gloss-coated cardstock for stronger reflectance and deeper blacks, if the brand relies on photo-like contrast.
- Natural or linen-finish cardstock for a pronounced fiber look, if you want texture that reads across distance and close-up.
- Velvet or soft-touch cardstock for low-glare tactility, if the packaging uses spot highlights and touch-points.
Cardstock Thickness and Weight
The thickness and weight of cardstock are critical factors that influence its durability, flexibility, and suitability for specific applications. These attributes are measured in points (pt) and pounds (lbs) or grams per square meter (GSM).
Thickness
Cardstock thickness is measured in points, with one point equal to 0.001 inches. Common thicknesses include:
- 12pt: 0.012 inches, suitable for lightweight applications.
- 14pt: 0.014 inches, ideal for premium and sturdy applications.
- 16pt: 0.016 inches, used for professional and durable materials.
- 24pt: 0.024 inches, preferred for upscale and formal uses.
Weight
Cardstock weight is measured in pounds (lbs) or GSM. Common weight ranges include:
- 65 lbs to 80 lbs: Lightweight and flexible, suitable for crafting and decorative purposes.
- 100 lbs to 120 lbs: Heavier and more durable, ideal for packaging and professional printing.
How is Cardstock Manufactured?
Cardstock is manufactured by pressing and drying layers of wood pulp under high pressure. The process involves several stages:
- Raw Material Preparation: Wood pulp is mixed with water to form a slurry.
- Sheet Formation: The slurry is spread into thin sheets and pressed to remove excess water.
- Drying and Calendaring: The sheets are dried and smoothed to achieve the desired texture and thickness.
- Coating and Finishing: Optional coatings, such as matte or glossy finishes, are applied to enhance appearance and functionality.
Uses of Cardstock
Cardstock is a versatile material used in various industries. Its durability and ability to take finishes (matte/gloss/foil) make it a practical choice when you need crisp branding on packaging or print pieces.
- Packaging: Cardstock is widely used in custom packaging for products such as cosmetics, electronics, and food items. Its rigidity and smooth surface allow for high-quality printing and branding.
- Business Cards and Marketing Materials: The professional appearance and durability of cardstock make it ideal for business cards, brochures, and postcards. It supports intricate designs and vibrant colors, enhancing brand visibility.
- Invitations and Announcements: Cardstock is commonly used for wedding invitations, formal announcements, and event programs. Its thickness and finish options provide a premium feel and luxurious look.
- Custom Branding: Businesses use cardstock for custom tags, labels, and promotional materials. Its versatility allows for unique designs that align with brand identity.
Cardstock Specifications for Packaging Use Cases
Cardstock weight, thickness, and finish define how branding artwork survives handling, how cartons crease, and how inserts support the product. The ranges below map to common packaging applications that manufacturers print and assemble at commercial scale.
| Packaging application | Recommended GSM | Recommended thickness | Finish/coating notes |
|---|---|---|---|
| Retail sleeves and product wraps | 200–250 GSM | 0.30–0.45 mm | Use matte or satin finishes to reduce glare on logos and barcodes. Add aqueous coating for scuff resistance. |
| Folding cartons (1–2 panel brands) | 250–300 GSM | 0.45–0.60 mm | Choose coated stocks for consistent ink laydown on gradients and solid blacks. Use spot gloss sparingly on high-coverage areas. |
| Rigid-feel box walls and cartons | 300–450 GSM | 0.60–0.90 mm | Use soft-touch or film lamination when fingerprints and sleeve-to-table abrasion affect presentation. |
| Tray inserts and product backers | 320–450 GSM | 0.75–1.20 mm | Select finishes that resist rubbing at contact points. Confirm coating compatibility with die-cutting tolerance. |
Check the print and finishing spec together. Coatings change surface friction, ink absorption, and scuff behavior, so the final look depends on both the GSM and the finish system used for commercial printing.
Which Finishing Techniques are Used on Cardstock?
Cardstock finishing combines coatings and print effects that affect gloss level, scratch resistance, and scuff performance. Common options include aqueous or UV varnish, matte or gloss lamination, spot-UV, embossing or debossing, and foil stamping.
Which Cardstock Weight Range Fits Common Commercial Packaging Printing?
Cardstock weights typically support commercial packaging projects from about 200 to 450 gsm (0.5 to 1.0 pt). Select a basis weight that matches the required stiffness, then confirm printer feed settings for the highest thickness used in your run.
Does Cardstock Require Different Printer Settings than Standard Paper?
Yes, cardstock requires feed and thickness management. Adjust tray and gripper settings for heavier grades and test registration on the press format before full production, especially for dielines and fine line artwork.
How to Choose Cardstock for Packaging?
Choose cardstock by weight, thickness, and surface finish for the print method and packaging function, then verify compatibility with your press, coatings, and dielines. Request samples in the exact GSM/weight you plan to print, confirm stiffness and fold performance, and run a short pre-production test print to validate color, contrast, and coating adhesion.
- Weight choice: Match the board weight to the package structure (insert card, sleeve, folding box) and handling requirement. Example: 200 to 350 gsm supports many folding and wrapping formats.
- Finish selection: Pick a surface finish that supports your branding needs and finishing steps. Example: matte reduces glare for label readability, and gloss increases visual contrast on coated inks.
- Print compatibility: Select cardstock that accepts the ink and process used in production. Example: coated cardstock supports higher ink density for fine text and logos in lithography and digital toner workflows.
- Thickness and die tolerance: Verify thickness against your dieline stack-up so folds, edges, and closures seat correctly. Example: confirm edge clearances for sleeves and blister-style pack inserts.
- Finishing add-ons: Confirm the cardstock grade can take your finishing requirements. Example: foil stamping and spot UV require consistent coating coverage to avoid dull spots.
