Blockout posters are a cost-effective solution when you need bold visuals that won’t let any background distractions show through. Made from thick 12pt C2S stock, these posters are created by laminating two coated sheets with a black inner layer that completely blocks light, ensuring 100% opacity and crisp, vibrant graphics from edge to edge.
The semi-gloss finish offers just the right touch of shine while keeping colors sharp and professional. Perfect for indoor use, blockout posters are a smart choice for P.O.P. displays, trade shows, event signage, political campaigns, product launches, and grand openings.
Whether you're promoting a sale, boosting visibility at an event, or showcasing your brand in-store, blockout posters deliver high impact without the high cost.

Design guidelines

We recommend using our templates and guides for preparing your print-ready PDF.

You can download our guides and templates in the template section. Remember to delete the template layers before exporting your design to PDF.

If you already have a design, no worries; we accept other file formats, including JPEG, PNG, or EPS.

For photographic content, high-resolution JPEGs are recommended, preferably without compression. For graphics or text-based content, we recommend print-ready, vector-based PDFs. For content that is a combination of graphics and photography, we suggest using print-ready PDFs to ensure the best quality.

Use CMYK as the color mode.

Prepare your files using CMYK as the color mode, not RGB. Use color mode FOGRA39 (ISO Coated v2). If you are unsure of the color mode of your file, don't worry we can always convert this for you. Keep in mind this can cause the colours to differ from the original file.

Resolution of at least 300 dpi.

Make sure the resolution of the images and graphics in your artwork are at least 300 dpi.

Add 0.125(in) bleed and keep 0.125(in) safety margin

During production, there might be a slight cut deviation. To avoid any issues, we recommend the following:

Add a 0.125 inch bleed around all edges of your design.
Keep important elements 0.125 inches away from the edge or folding lines.
Avoid using borders or frames on smaller formats like labels or business cards.

Text and fonts specifications (Min. font size is 6 pt)

For this product, the minimum font size is 6 pt. To avoid any issues, we recommend the following:

Fonts must be embedded or outlined.
If your design contains small black text, make sure it is 100 % black (Cyan: 0 Magenta: 0 Yellow: 0 Black: 100).

Note that we don't check spelling or typographical errors.

Check line thickness.

Lines should be at least 0.25 pt. Negative lines should be at least 0.5 pt.

Check your artwork for overprint.

Make sure no elements in your artwork are set on overprint unless you want this effect in your design.

Make sure the ink coverage isn't higher than 300%.

Force Color Images to CMYK with a 260% ink limit (in Photoshop > Convert Color Profile > Photoshop 5 Default CMYK). Make sure the ink coverage isn't higher than 300%.

Using a border/frame is not recommended

It is recommended to count with a margin of error when stacks of copies are trimmed during the production process. This slight cutting deviation is usually not noticeable, however we recommend avoiding adding borders smaller than 0.125 inches in your design otherwise, the design might end up looking off-center.

Frequently asked questions

What are blockout posters?

Blockout posters are printed on thick 12pt C2S stock and include a black inner layer that blocks all light from passing through. This makes them ideal for double-sided printing or situations where background distractions need to be completely hidden.

What is 12pt C2S paper?

12pt C2S stands for 12-point Coated 2 Sides paper. It’s a thick, durable stock with a smooth, semi-gloss coating on both sides—perfect for rich color and professional-looking prints.

Why choose a blockout poster over a regular poster?

Blockout posters ensure 100% opacity, so no light or background visuals show through. This is especially useful for window displays, hanging signage, or mounting over other graphics where clean presentation matters.

Where are blockout posters typically used?

They’re great for P.O.P. displays, trade shows, political campaigns, product launches, retail promotions, and event signage—anywhere you need bold visuals with zero bleed-through.

Are blockout posters suitable for outdoor use?

Blockout posters are primarily intended for indoor use. If you need something for outdoor environments, we recommend waterproof or weatherproof materials like EndurACE for outdoor posters.
