Vinyl Banners 101: Everything Sign Shops Need to Know About Wholesale Banner Printing

Banners are one of the most reliably profitable product categories for sign shops. They have high perceived value relative to production cost, clients order them repeatedly for events and promotions, and the wide range of applications — from retail sale signs to trade show displays to outdoor event banners — means nearly every business you serve can benefit from a well-made banner program.

This guide breaks down everything you need to know to spec, sell, and profitably order wholesale banners through a trade-only printing partner: the difference between 13oz and 15oz vinyl, when to use each, what finishing options mean and when they matter, how to handle double-sided applications, and common mistakes that create expensive reprints.

13oz vs. 15oz Vinyl: The Most Common Spec Decision in Banner Printing

When a client orders a banner, the first material decision is weight. Banner vinyl is measured in ounces per square yard, and the most common wholesale options are 13oz and 15oz. Understanding the difference helps you spec the right product and avoid callbacks from clients whose banners fail prematurely — or cost them more than the job warranted.

13oz Standard Vinyl

The 13oz material is the industry workhorse. It is lighter, slightly less expensive, and handles most standard banner applications without issue. It is the appropriate choice for:

The 13oz vinyl is translucent enough that it is not ideal for applications where the banner is backlit or where show-through from one side to the other would be noticeable.

15oz Blockout Vinyl

The 15oz blockout vinyl is heavier, more opaque, and significantly more durable for extended outdoor exposure. The "blockout" refers to the construction: a solid black core between two vinyl faces that completely eliminates light and image transmission through the material. This makes 15oz blockout the correct choice for:

When in doubt for outdoor applications, spec 15oz. The cost difference is modest and the durability advantage is significant. Clients who get a banner that fails after two weeks of outdoor exposure will not return; clients who get a banner that still looks good after six months will.

Finishing Options: What They Mean and When to Use Each

Finishing is where many banner jobs get complicated — and where miscommunication between sign shop and client causes the most grief. Understanding exactly what each finishing option provides lets you confirm the spec before you order and deliver exactly what the client expects.

Standard Grommets

Standard grommet placement means grommets are placed at the four corners of the banner and approximately every 24 inches along the perimeter. This is appropriate for most banner applications where the client will be using bungee cords, rope, or zip ties to attach the banner to a fence, railing, scaffolding, or frame. Standard grommet placement is the default and is suitable for the vast majority of orders.

Custom Grommet Placement

Custom grommet placement allows you to specify exactly where grommets should be positioned — useful when the banner is being mounted to a specific structure with fixed attachment points, or when the client needs grommets centered on specific panel sections for visual balance. If a client provides a mounting diagram or specifies attachment point locations, note these in the order and include the grommet placement spec in your artwork files or order notes.

Pole Pockets

A pole pocket is a hemmed sleeve sewn along one or both edges of the banner through which a pole, dowel, or horizontal rail can be inserted. Pole pockets are used when the banner will be hung from a banner stand, suspended between two uprights, or displayed in a sleeve-style bracket. For trade show banner stands, retractable stands, and lobby display systems, always confirm the pole diameter required — pole pockets should be sized to fit the specific hardware the client is using.

Hemming

Hemming folds and welds the edges of the banner back on itself before grommets are added, significantly reinforcing the perimeter and reducing the risk of tears propagating from grommet holes under tension. All finished banners from SignMaster include hemming as standard — it is a sign of quality finishing and makes the banner more durable in windy outdoor applications.

Double-Sided Banners: Getting Them Right

Double-sided banners are one of the most frequently misspecced products in the industry. There are two approaches, each with a different workflow.

Double-Sided Print on Blockout Vinyl

This is the premium approach: print two separate images, one on each face of 15oz blockout vinyl. The blockout core prevents either side's image from showing through to the opposite face. This produces the cleanest, most professional result. It requires two separate artwork files and is priced accordingly. Use this approach for street banners, suspended lobby banners, and any application where both sides are equally prominent.

Back-to-Back Banners

Some shops produce "double-sided" banners by printing two separate single-sided banners and then zip-tying or sewing them together back-to-back. This is a workable field solution for simple rectangular formats but adds labor and complexity. The blockout vinyl approach above is cleaner and more reliable for most applications.

Maximum Sizes and When Roll Printing Makes Sense

SignMaster can produce finished banners up to 10 feet by 20 feet — covering the vast majority of outdoor banner applications. For banners larger than this, or for situations where your client handles their own hemming and grommeting, our banner roll program ships your order unfinished on a roll at up to 10 feet by 150 feet.

Banner rolls make sense for:

File Preparation for Wholesale Banner Orders

Resolution

For banners viewed at close range (under 10 feet), supply artwork at 100-150 DPI at the finished size in CMYK. For large outdoor banners viewed from a distance, 72-100 DPI at full size is acceptable and produces excellent results — the viewing distance means high resolution is not necessary and very large files create unnecessary complexity.

Bleed

Always supply artwork with a 0.5" to 1" bleed on all sides. Banners are hemmed and the hem consumes some of the edge area — without bleed, you risk seeing a white border at the edge of the finished product.

Grommet Clearance

Keep critical design elements (logos, text, phone numbers) at least 2 inches from the edge of the banner to avoid them being obscured by grommets or hems. If you are ordering custom grommet placement, note grommet positions in the artwork file or order notes.

Common Banner Mistakes to Avoid

Here are the most frequent banner ordering mistakes that result in reprints, callbacks, or unhappy clients:
