Choosing the Right Stock for Your Design

When it comes to poster printing, the design is only half the story. The paper you choose has just as much impact on how your final print looks, feels and performs. From lightweight promotional posters to premium display pieces, selecting the right stock can elevate your work from ordinary to professional in an instant.

 

If you’re deciding between 90gsm, 120gsm and 170gsm uncoated papers, or 115gsm, 150gsm, 170gsm, 250gsm and 350gsm silk, this guide will help you understand what each option is best suited for.

Poster Paper Types: Uncoated vs Silk

Uncoated versus silk poster printing paper

Before looking at weights, it’s important to understand the two main finishes:

Uncoated paper

Uncoated paper has a natural, textured feel with no surface coating. It absorbs ink more readily, resulting in a softer, more muted print finish. It’s often used when readability and practicality matter more than visual impact.

Silk paper

Silk paper has a smooth, lightly coated surface that sits between matt and gloss. It produces sharper images, richer colours and a more polished finish, making it ideal for high-impact posters and marketing materials.

Uncoated Poster Paper Options

Uncoated stock is ideal when you want a more natural, understated look or need something cost-effective for short-term use.

90gsm uncoated

This is a lightweight option, best suited for:

  • Draft posters or internal notices
  • Large volume print runs where cost is a factor
  • Temporary signage or information sheets

It is not designed for heavy-duty display use, as it can feel thin and less durable.

120gsm uncoated

A step up in quality while still economical:

  • Office posters and notices
  • Educational materials
  • Short-term promotional displays

It offers a better balance of durability and affordability without becoming too heavy.

170gsm uncoated

The premium end of uncoated stock:

  • Artistic prints with a natural feel
  • Posters that require more durability
  • Gallery-style or typographic designs

This weight provides a more substantial feel while still maintaining the soft, non-reflective finish of uncoated paper.

Silk Poster Paper Options

Silk paper is the go-to choice for vibrant, professional-quality poster printing. It enhances colour depth and produces a smoother, more refined appearance.

115gsm silk

Lightweight but visually strong:

  • Budget marketing posters
  • Indoor advertising
  • Short-term promotional campaigns

It offers a professional finish at a lower cost.

150gsm silk

A popular mid-range option:

  • Event posters
  • Retail promotions
  • General marketing materials

This weight strikes a great balance between cost, durability and print quality.

170gsm silk

A versatile premium standard:

  • High-quality promotional posters
  • Exhibitions and trade shows
  • Professional display graphics

It produces sharper images and feels noticeably more substantial.

250gsm silk

A heavyweight option designed for impact:

  • Premium advertising posters
  • High-end branding displays
  • Long-term indoor signage

This stock has a strong, board-like feel and holds up well in high-visibility environments.

350gsm silk

The ultimate premium finish:

  • Luxury promotional posters
  • Presentation pieces
  • Display prints where quality is everything

This is the thickest and most durable option, offering a truly high-end feel that communicates quality instantly.

Key Factors for Poster Printing

Key factors For poster printing

Choosing the best paper depends on three key factors:

1. Purpose of the poster

  • Temporary notice → lighter uncoated stock
  • Marketing or advertising → silk paper
  • Premium branding → heavyweight silk (250gsm or 350gsm)

2. Viewing distance

  • Posters viewed up close benefit from smoother silk finishes
  • Large wall or outdoor-facing posters may not require heavy stock but should still be durable

3. Budget vs impact

  • Lower gsm = more economical
  • Higher gsm = more durable and premium appearance

Final Thoughts

There is no single “best” paper for poster printing—it all depends on how your design will be used. If you want a natural, understated look, uncoated paper is ideal. If you want vibrant colours and a professional finish, silk paper is the clear winner.

 

For most marketing and promotional work, 150gsm or 170gsm silk tends to be the sweet spot, while 250gsm and 350gsm silk are perfect when you want to make a strong visual statement.
