How to get a beautiful print result with Flash Poster?

Flash Poster lets you create and print your posters directly from your smartphone. To achieve professional-looking results, a few simple adjustments can make all the difference. Here’s everything you need to know to print your posters successfully with Flash Poster.

Available formats

Flash Poster lets you print your posters in two standard sizes:

• A4 (21 × 29.7 cm): the most common size, ideal for retail locations, storefronts, counters, and wall displays.
• A5 (14.8 × 21 cm): a compact size, perfect for small spaces, flyers, or quick table displays.

Both of these formats are supported directly by the app and are compatible with standard home printers.

What kind of paper should you choose for printing your poster?

Choosing the right paper is the most important factor in achieving a beautiful finish. After conducting several comparative tests, here are our recommendations:

Semi-gloss photo paper: the best choice

Semi-gloss photo paper is the go-to choice for printing posters with Flash Poster. It works well with all of the app’s templates, whether they are text-heavy, illustrated, or feature a photo background.

• Vivid, high-contrast color reproduction
• Slightly satin finish, without excessive glare
• Ideal for templates with a photo background or full-page image
• Compatible with all color inkjet and laser printers

Matte photo paper: for illustrated templates

Matte photo paper can also produce good results, but only with certain illustrated templates from Flash Poster. It is not recommended for templates with photo backgrounds or solid dark colors, which require the saturation provided by semi-gloss paper.

• Matte, non-reflective surface
• A softer look, perfect for minimalist and illustrated designs
• Not recommended for photo backgrounds: the colors lack depth

Standard paper: avoid

Printing on standard paper (80 gsm) is possible, but the results are significantly less professional: dull colors, visible texture, and limited durability. Reserve this option solely for test prints before the final print run.

Tips for Setting Up Your Printer

The printer settings are just as important as the choice of paper. Here are the settings you should check before each print job:

• Paper size: Make sure the selected size matches the size of your poster (A4 or A5).
• Paper type: Select "Photo Paper" or "Glossy/Semi-Gloss Paper" from the print options so that the printer can adjust the ink application.
• Print quality: Select the highest quality available (usually "High Quality" or "Photo").
• Borderless printing: Select the "Borderless" or "Full Page" option so that the poster fills the entire page.
• Orientation: Flash Poster generates its posters in portrait mode—make sure the orientation is set to Portrait.

Printing time: immediate from your home

One of the major advantages of Flash Poster is its speed. If you have the app and a home printer, the poster can be printed in just a few seconds, with no wait for delivery.

This is especially useful for retailers and artisans who need a sign right away: price changes, daily specials, or urgent information at the point of sale.

Should I laminate my poster?

Laminating is not required, but it is strongly recommended if your poster will be exposed to the elements or in a humid environment (patio, outdoor display, storefront window prone to condensation, etc.).

Laminating protects the poster from moisture, splashes, and wear and tear. Most print shops offer this service quickly, and there are also inexpensive cold laminators available for home use.

Summary: When should you laminate?

• ✅ Oui : affiche exposée en extérieur, zone humide, marché, food truck, terrasse
• ⬜ Facultatif : affiche en intérieur avec peu de manipulation
• ❌ Not required : affiche temporaire ou test d’impression
